The melting brain

It’s not just the planet and not just our health – the impact of a warming climate extends deep into our cortical fissures.

by Clayton Page Aldern + BIO

In February 1884, the English art critic and polymath John Ruskin took the lectern at the London Institution for a pair of lectures on the weather. ‘The Storm-Cloud of the Nineteenth Century’ was his invective against a particular ‘wind of darkness’ and ‘plague-cloud’ that, in his estimate, had begun to envelope Victorian cities only in recent years. He had been taking careful meteorological measurements, he told a sceptical audience. He railed against the ‘bitterness and malice’ of the new weather in question; and, perhaps more importantly, about how it mirrored a certain societal ‘moral gloom’. You could read in us what you could read in the weather, he suggested.

It was easy that February, and perhaps easy today, to disregard any alleged winds of darkness as the ravings of a madman. Clouds are clouds: even if Ruskin’s existed – which was a question of some contemporaneous debate – it would be untoward to imagine they bore any relationship with the human psyche. As Brian Dillon observed of the cloud lectures in The Paris Review in 2019, it can be hard to tell where Ruskin’s ‘bad weather ends and his own ragged, doleful mood begins.’ In 1886, Ruskin suffered a mental breakdown while giving a talk in Oxford. By the end of his life at the turn of the century, he was widely considered insane. His ramblings on meteorology and the human spirit aren’t exactly treated with the same gravitas as his books on J M W Turner.

And yet, for Ruskin, the clouds weren’t just clouds: they were juiced up by a ‘dense manufacturing mist’, as he’d noted in a diary entry. The plague-clouds embodied the miasma of the Industrial Revolution; the moral gloom was specifically that which arose from the rapid societal and environmental changes that were afoot. Ruskin’s era had seen relentless transformation of pastoral landscapes into industrial hubs. Everything smelled like sulphur and suffering. Soot-filled air, chemical and human waste, the clamour of machinery – these were more than just physical nuisances. They were assaults on the senses, shaping moods and behaviour in ways that were not yet fully understood.

Ruskin believed that the relentless pace of industrialisation, with its cacophony of tools and sprawling factories and environmental destruction, undermined psychological wellbeing: that the mind, much like the body, required a healthy social and physical environment to thrive. This was actually a somewhat new idea. (Isaac Ray, a founder of the American Psychiatric Association, wouldn’t define the idea of ‘mental hygiene’, the precursor to mental health, until 1893.) Instability in the environment, for Ruskin, begot instability in the mind. One reflected the other.

M ore than a century later, as we grapple with a new suite of breakneck environmental changes, the plague-clouds are again darkly literal. Global average surface temperatures have risen by about 1.1°C (2°F) since the pre-industrial era, with most of this warming occurring in the past 40 years. Ice is melting; seas are steadily rising; storms are – well, you know this story. And yet, most frequently, it is still a story of the world out there: the world outside of us. The narrative of climate change is one of meteorological extremes, economic upheaval and biodiversity losses. But perhaps it is worth taking a maybe-mad Ruskin seriously. What of our internal clouds? As the climate crisis warps weather and acidifies oceans and shatters temperature records with frightening regularity, one is tempted to ask if our minds are changing in kind.

Here are some of the most concerning answers in the affirmative. Immigration judges are less likely to rule in favour of asylum seekers on hotter days. On such days, students behave as if they’ve lost a quarter-year of education, relative to temperate days. Warmer school years correspond to lower rates of learning. Temperature predicts the incidence of online hate speech. Domestic violence spikes with warmer weather. Suicide , too.

In baseball, pitchers are more likely to hit batters with their pitches on hot days

But you already know what this feels like. Perhaps you’re more ornery in the heat. Maybe you feel a little slow in the head. It’s harder to focus and easier to act impulsively. Tomes of cognitive neuroscience and behavioural economics research back you up, and it’s not all as dire as domestic violence. Drivers honk their horns more frequently (and lean on them longer) at higher temperatures. Heat predicts more aggressive penalties in sport. In baseball, pitchers are more likely to hit batters with their pitches on hot days – and the outdoor temperature is an even stronger predictor of their tendency to retaliate in this manner if they’ve witnessed an opposing pitcher do the same thing.

In other words: it would appear the plague-clouds are within us, too. They illustrate the interconnectedness of our inner and outer worlds. They betray a certain flimsiness of human agency, painting our decision-making in strokes of environmental influence far bolder than our intuition suggests. And they throw the climate crisis into fresh, stark relief: because, yes, as the climate changes, so do we.

T he London Institution closed in 1912. These days, when you want to inveigh against adverse environmental-mind interactions, you publish a paper in The Lancet . And so that is what 24 mostly British, mostly clinical neurologists did in May 2024, arguing that the ‘incidence, prevalence, and severity of many nervous system conditions’ can be affected by global warming. For these researchers, led by Sanjay Sisodiya, professor of neurology at University College London in the UK, the climate story is indeed one of internal clouds.

In their survey of 332 scientific studies, Sisodiya and his colleagues show that climatic influence extends far beyond behaviour and deep into cortical fissures. Aspects of migraine, stroke, seizure and multiple sclerosis all appear to be temperature dependent. In Taiwan, report the authors, the risk of schizophrenia hospitalisation increases with widening daytime temperature ranges. In California , too, ‘hospital visits for any mental health disorder, self-harm, intentional injury of another person, or homicide’ rise with broader daily temperature swings. In Switzerland , hospitalisations for psychiatric disorders increase with temperature, with the risk particularly pronounced for those with developmental disorders and schizophrenia.

Outside the hospital, climate change is extending the habitable range of disease vectors like ticks, mosquitoes and bats, causing scientists to forecast an increased incidence of vector-borne and zoonotic brain maladies like yellow fever, Zika and cerebral malaria. Outside the healthcare system writ large, a changing environment bears on sensory systems and perception, degrading both sensory information and the biological tools we use to process it. Outside the realm of the even remotely reasonable, warming freshwater brings with it an increased frequency of cyanobacterial blooms, the likes of which release neurotoxins that increase the risk of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig’s disease).

Experiencing natural disasters in utero greatly increases children’s risk of anxiety, depression and ADHD

Indeed, recent studies suggest that climate change may be exacerbating the already substantial burden of neurodegenerative diseases like Parkinson’s and Alzheimer’s. In countries with warmer-than-average climates, more intense warming has been linked to a greater increase in Parkinson’s cases and, as Sisodiya et al note, the highest forecasted rates of increase in dementia prevalence are ‘expected to be in countries experiencing the largest effects of climate change’. Similarly, short-term exposure to high temperatures appears to drive up emergency department visits for Alzheimer’s patients. The air we breathe likely plays a complementary role: in Mexico City, for example, where residents are exposed to high levels of fine particulate matter and ozone from a young age, autopsies have revealed progressive Alzheimer’s pathology in 99 per cent of those under the age of 30.

The risks aren’t limited to those alive today. In 2022, for example, an epidemiological study revealed that heat exposure during early pregnancy is associated with a significantly increased risk of children developing schizophrenia, anorexia and other neuropsychiatric conditions. High temperatures during gestation have long been known to delay neurodevelopment in rats. Other scientists have shown that experiencing natural disasters in utero greatly increases children’s risk of anxiety, depression, attention-deficit/hyperactivity disorder and conduct disorders later in life. Such effects cast the intergenerational responsibilities of the Anthropocene in harsh new light – not least because, as Sisodiya and colleagues write, there is a tremendous ‘global disparity between regions most affected by climate change (both now and in the future) and regions in which the majority of studies are undertaken.’ We don’t know what we don’t know.

What we do know is that the brain is emerging, in study after study, as one of climate change’s most vulnerable landscapes.

It is a useful reorientation. Return to the horn-honking and the baseball pitchers for a moment. A focus on the brain sheds some potential mechanistic light on the case studies and allows us to avoid phrases like ‘wind of darkness’. Higher temperatures, for example, appear to shift functional brain networks – the coordinated behaviour of various regions – toward randomised activity. In extreme heat, scientists have taken note of an overworked dorsolateral prefrontal cortex (dlPFC), the evolutionarily new brain region that the neuroendocrinologist Robert M Sapolsky at Stanford University in the US calls ‘the definitive rational decider in the frontal cortex’. The dlPFC limits the degree to which people make impulsive decisions; disrupted dlPFC activity tends to imply a relatively heightened influence of limbic structures (like the emotionally attuned amygdala) on behaviour. More heat, less rational decision-making.

When extreme heat reaches into your mind and tips your scales toward violence, it is constraining your choices

The physicality of environmental influence on the brain is more widespread than the dlPFC – and spans multiple spatial scales. Heat stress in zebrafish, for example, down-regulates the expression of proteins relevant to synapse construction and neurotransmitter release. In mice, heat also triggers inflammation in the hippocampus, a brain region necessary for memory formation and storage. While neuroinflammation often plays an initially protective role, chronic activation of immune cells – like microglia and astrocytes – can turn poisonous, since pro-inflammatory molecules can damage brain cells in the long run. In people, hyperthermia is associated with decreased blood flow to this region. Psychologists’ observations of waning cognition and waxing aggression at higher temperatures makes a world of sense in the context of such findings.

The nascent field of environmental neuroscience seeks to ‘understand the qualitative and quantitative relationships between the external environment, neurobiology, psychology and behaviour’. Searching for a more specific neologism – since that particular phrase also encompasses environmental exposures like noise, urban development, lighting and crime – we might refer to our budding, integrative field as climatological neuroepidemiology. Or, I don’t know, maybe we need something snappier for TikTok. Neuroclimatology? Ecological neurodynamics?

I tend to prefer: the weight of nature.

The weight forces our hands, as in the case of the behavioural effects highlighted above. When extreme heat reaches into your mind and tips your scales toward violence, it is constraining your choices. By definition, impulsive decisions are rooted in comparatively less reflection than considered decisions: to the extent that a changing climate influences our reactions and decision-making, we should understand it as compromising our perceived free will. The weight of nature is heavy. It displaces us.

It is also a heavy psychological burden to carry. You are likely familiar with the notion of climate anxiety . The phrase, which tends to refer to a near-pathological state of worry and fear of impending environmental destruction, has never sat particularly well with me. Anxiety, as defined by the Diagnostic and Statistical Manual , is usually couched in terms of ‘excessive’ worry. I’m not convinced there’s anything excessive about seeing the climatic writing on the wall and feeling a sense of doom. Perhaps we ought to consider the climate-anxious as having more developed brains than the rest of the litter – that the Cassandras are the only sane ones left.

I ’m not exactly joking. Neuroscience has begun to study the brains in question, and not for nothing. The midcingulate cortex, a central hub in the brain’s threat-detection circuitry, may hold some clues to the condition’s biological basis: in one 2024 study , for example, researchers at Northern Michigan University in the US found that people who reported higher levels of anxiety about climate change showed distinct patterns of brain structure and function in this region, relative to those with lower levels of climate anxiety – and irrespective of base levels of anxiety writ large. In particular, the climate-anxious brain appears to play host to a smaller midcingulate (in terms of grey matter), but one that’s functionally more connected to other key hubs in the brain’s salience network, a system understood to constantly scan the environment for emotionally relevant information. In the salience network, the midcingulate cortex works hand in hand with limbic structures like the amygdala and insula to prepare the body to respond appropriately to this type of information. In people with climate anxiety, this network may be especially attuned to signals of climate-related threats.

Rather than indicating a deficiency, then, a diminutive midcingulate might reflect a more efficient, finely honed threat-detection system. The brain is well known to prune redundant connections over time, preserving only the most useful neural pathways. Selective sculpting, suggest the Michigan researchers, may allow the climate-anxious brain to process worrisome information more effectively, facilitating rapid communication between the midcingulate and other regions involved in threat anticipation and response. In other words, they write, the climate-anxious midcingulate might be characterised by ‘more efficient wiring’.

This neural sensitivity to potential dangers could be both a blessing and a curse. On one hand, it may attune some people to the very real perils of the future. The midcingulate is critical for anticipating future threats, and meta-analyses have found the region to be consistently activated when people contemplate unpredictable negative outcomes. Given the looming spectre of climate catastrophe, a hair-trigger threat-detection system could be an adaptive asset.

Climate anxiety is not just a sociocultural phenomenon. It has a theoretically identifiable neural correlate

On the other hand, argue the researchers:

[T]he complexity, uncertainty, as well as temporal and geographical distance of the climate crisis, in addition to its global nature, may lead individuals to deprioritising the risks associated with climate change, or becoming overwhelmed and disengaged – a state sometimes referred to as ‘eco-paralysis’.

An overactive midcingulate has been implicated in clinical anxiety disorders, and the new findings suggest that climate anxiety shares some of the same neural underpinnings. (It’s important to recall that climate anxiety seems to be distinct from generalised anxiety, though, as the brain differences observed in the Michigan study couldn’t be explained by overall anxiety levels.)

Ultimately, while speculative, these findings suggest that climate anxiety is not merely a sociocultural phenomenon, but one with theoretically identifiable neural correlates. They provide a potential biological framework for understanding why some people may be more psychologically impacted by climate change than others. And they raise intriguing questions about whether the brains of the climate anxious are particularly well-suited for confronting the existential threat of a warming world – or whether they are vulnerable to becoming overwhelmed by it. In all cases, though, they illustrate that world reaching inward.

T here is perhaps a flipside to be realised here. A changing climate is seeping into our very neurobiology. What might it mean to orient our neurobiology toward climate change?

Such is the premise of a 2023 article in Nature Climate Change by the neuroscientist Kimberly Doell at the University of Vienna in Austria and her colleagues, who argue that the field is well positioned to inform our understanding of climate-adaptation responses and pro-environmental decision-making. In the decades since Ruskin shook his fists at the sky, environmental neuroscience has begun to probe the reciprocal dance between organisms and their ecological niches. We know now that the textures of modern environments – green spaces, urban sprawl, socioeconomic strata – all leave their mark on the brain. Climate change is no different.

Accordingly, argue Doell et al, scientists and advocates alike can integrate findings from neuroscience to improve communications strategies aimed at spurring climate action. They want to turn the tables, taking advantage of insights from neurobiology and cognitive neuroscience to more effectively design climate solutions – both within ourselves and for society as a whole.

The Anthropocene’s fever dream is already warping our wetware

We have models for this type of approach. Poverty research, for instance, has long implicated socioeconomic conditions with subpar health. In more recent years, neuroscience has reverse-engineered the pathways by which poverty’s various insults – understimulation, toxic exposures, chronic stress – can erode neural architecture and derail cognitive development. Brain science alone won’t solve poverty, yet even a limited understanding of these mechanisms has spurred research in programmes like Head Start, a family-based preschool curriculum that has been shown to boost selective attention (as evident in electrophysiological recordings) and cognitive test scores. While the hydra of structural inequity is not easily slain, neuroscientists have managed to shine some light on poverty’s neural correlates, flag its reversible harms, and design precision remedies accordingly. This same potential, argue Doell and her colleagues, extends to the neuroscience of climate change.

To realise this potential, though, we need to further understand how the Anthropocene’s fever dream is already warping our wetware. Social and behavioural science have begun cataloguing the psychological fallout of a planet in flux, but a neural taxonomy of climate change awaits. The field’s methodological and conceptual arsenal is primed for the challenge, but honing it will demand alliances with climate science, medicine, psychology, political science and beyond.

Some are trying. For example, the Kavli Foundation in Los Angeles, US, recognising a need for answers, last year put out a call for scientists to investigate how neural systems are responding to ecological upheaval. With a trial $5 million, the foundation aims to illuminate how habitat loss, light pollution and other environmental insults may be influencing the molecular, cellular and circuit-level machinery of brains, human and otherwise. The central question is: in a biosphere where change is the only constant, are neural systems plastic enough to keep pace, or will they be left struggling to adapt?

The first wave of researchers to take up Kavli’s challenge are studying a diverse array of creatures, each uniquely positioned to reveal insights about the brain’s resilience in the face of planetary disruption. Wolfgang Stein at Illinois State University in the US and Steffen Harzsch at University of Greifswald in Germany, for example, focus on crustaceans, seeking to understand how their neural thermal regulators cope with rising temperatures in shallow and deep waters. Another group has targeted the brains of cephalopods, whose RNA-editing prowess may be key to their ability to tolerate plummeting oxygen levels in their increasingly suffocating aquatic habitats. A third Kavli cohort, led by Florence Kermen at University of Copenhagen in Denmark, is subjecting zebrafish to extreme temperatures, scouring their neurons and glial cells for the molecular signatures that allow them to thrive – even as their watery world heats up.

These initial investments have sparked federal curiosity. In December 2023, the US National Science Foundation joined forces with Kavli, inviting researchers to submit research proposals that seek to probe the ‘modulatory, homeostatic, adaptive, and/or evolutionary mechanisms that impact neurophysiology in response to anthropogenic environmental influence’. We may not be in arms-race territory yet, but at least there’s a suggestion that we’re beginning to walk in the right direction.

T he brain, that spongy command centre perched atop our spinal cord, has always been a black box. As the climate crisis tightens its grip, and the ecological ground beneath our feet grows ever more unsteady, the imperative to pry it open and peer inside grows more urgent by the day. Already, we’ve begun to glimpse the outlines of a new neural cartography, sketched in broad strokes by the likes of Sisodiya and his colleagues. We know now that the brain is less a static lump of self-regulating tissue than it is a dynamic, living landscape, its hills and valleys shaped by the contours of our environment. Just as the Greenland ice sheet groans and buckles under the heat of a changing climate, so too do our synapses wither and our neurons wink out as the mercury rises. Just as rising seas swallow coastlines, and forests succumb to drought and flame, the anatomical borders of our brains are redrawn by each new onslaught of environmental insult.

But the dialogue between brain and biosphere is not a one-way street. The choices we make, the behaviours we pursue, the ways in which we navigate a world in crisis – all of these decisions are reflected back onto the environment, for good or for ill. So, I offer: in seeking to understand how a changing climate moulds the contours of our minds, we must also reckon with how the architecture of our thoughts might be renovated in service of sustainability.

Bit by bit, synapse by synapse, we can chart a course through the gathering plague-cloud

The cartographers of the Anthropocene mind have their work cut out for them. But in the hands of neuroscience – with its shimmering brain scans and humming electrodes, its gene-editing precision and algorithmic might – there is something approaching a starting point. By tracing the pathways of environmental impact to their neural roots, and by following the cascading consequences of our mental processes back out into the world, we might yet begin to parse the tangled web that binds the fates of mind and planet.

This much is clear: as the gears of the climate crisis grind on, our brains will be swept along for the ride. The question is whether we’ll be mere passengers, or whether we’ll seize the controls and steer towards something resembling a liveable future. The weight of nature – the immensity of the crisis we face – is daunting. But it need not be paralysing. Bit by bit, synapse by synapse, we can chart a course through the gathering plague-clouds. It was Ruskin, at a slightly more legible moment in his life, who offered: ‘To banish imperfection is to destroy expression, to check exertion, to paralyse vitality.’ Even if we somehow could, we ought not banish the alleged imperfections of environmental influence on the mind. Instead, we ought to read in them an intimate, vital relationship between self and world.

In this, climatological neuroepidemiology – young and untested though it may be – is poised to play an outsized role. In gazing into the black box of the climate-altered mind, in illuminating the neural circuitry of our planetary predicament, the field offers something precious: a flicker of agency in a world that often feels as if it’s spinning out of control. It whispers that the levers of change are within reach, lodged in the squishy confines of our crania, waiting to be grasped. And it suggests that, even as the weight of nature presses down upon us, we might yet find a way to press back.

Her research employs multimodal discourse analysis of elementary students engaged in a collaborative engineering design challenge in order to examine students’ decision-making practices. Prior to resuming graduate studies, she was a secondary science teacher and conducted molecular biology research.

Subject(s): Earth Science
Topic: Climate Change and Sustainability
Grade/Level: 9-12 (can be adapted to grades 6-8)
Objectives: Students will be able to write a scientific argument using evidence and reasoning to support claims. Students will also be able to reflect on the weaknesses in their own arguments in order to improve their argument and then respond to other arguments.
Suggested Time Allotment: 4-5 hours (extra time for extension)

This lesson is derived from Dr. Peter Buckland’s sustainability presentation for the Center for Global Studies . Dr. Peter Buckland, a Penn State alumnus, is a postdoctoral fellow for the Sustainability Institute. He has drawn together many resources for teaching about climate change, sustainability, and other environmental issues.

While there are many resources for teaching about climate change and sustainability, it may be tough to figure out where to start. There are massive amounts of data available to the general public and students need help searching for good sources of evidence. Prior to launching into a search, it would be worthwhile figuring out what the students already know about climate change, where they learned it, and how they feel about efforts to reduce our carbon footprint. There are many options for eliciting prior knowledge, including taking online quizzes, whole-class discussion, or drawing concept maps. For this initial step, it is important that students feel comfortable to share, without engaging in disagreements. The main idea is to increase students’ understanding about global warming, rather than focus on the potential controversial nature of this topic.

A major goal of this unit is to engage students in co-constructing evidence-based explanations through individual writing, sharing, re-writing, group discussion, and whole group reflection. The argumentation format presented here contains claims supported by evidence and reasoning (Claims Evidence Reasoning – CER). Argumentation in this sense is different from how the word “argument” is used in everyday language. Argumentation is a collaborative process towards an end goal, rather than a competition to win (Duschl & Osborne, 2002). Scientific argumentation is the process of negotiating and communicating findings through a series of claims supported by evidence from various sources along with a rationale or reasoning linking the claim with the evidence. For students, making the link between claim and evidence can be the most difficult part of the process.

Where does the evidence come from?

Evidence and data are often used synonymously, but there is a difference. Evidence is “the representation of data in a form that undergirds an argument that works to answer the original question” (Hand et al., 2009, p. 129). This explains why even though scientists may use the same data to draw explanations from, the final product may take different forms depending on which parts of the data were used and how. For example, in a court case experts from opposing sides may use the same data to persuade the jury to reach different conclusions. Another way to explain this distinction to students is “the story built from the data that leads to a claim is the evidence” (Hand et al., 2009, p. 129). Evidence can come from many sources – results from controlled experiments, measurements, books, articles, websites, personal observations, etc. It is important to discuss with students the issue of the source’s reliability and accuracy. When using data freely available online, ask yourself: Who conducted the study? Who funded the research? Where was it published or presented?

What is a claim and how do I find it?

A scientific claim is a statement that answers a question or an inference based on information, rather than just personal opinion.

How can I connect the claim(s) with the evidence?

That’s where the justification or reasoning comes in. This portion of the argument explains why the evidence is relevant to the claim or how the evidence supports the claim.

Implementation

Learning context and connecting to state standards.

This interdisciplinary unit can be used in an earth science class or adapted to environmental science, chemistry, or physics. The key to adapting the lesson is guiding students to sources of data that fit the discipline they are studying.

For earth science , students can explain the difference between climate and weather, describe the factors associated with global climate change, and explore a variety of data sources to draw their evidence from. Pennsylvania Academic Standards for earth and space science (secondary): 3.3.12.A1, 3.3.12.A6, 3.3.10.A7.

For environmental science , students can analyze the costs and benefits of pollution control measures. Pennsylvania Academic Standards for Environment and Ecology (secondary): 4.5.12.C.

For chemistry and physics , students can explain the function of greenhouse gases, construct a model of the greenhouse effect, and model energy flow through the atmosphere. Pennsylvania Academic Standards for Physical Sciences (secondary): 3.2.10.B6.

New Generation Science Standards (NGSS) Connections

Human impacts and global climate change are directly addressed in the NGSS. Disciplinary Core Ideas (DCI): HS-ESS3-3, HS-ESS3-4, HS-ESS3-5, HS-ESS3-6.

Lesson 1: Introduction to climate change

What are greenhouse gases and the greenhouse effect? (sample answer: greenhouse gases like carbon dioxide and methane contribute to overall heating of the atmosphere; these gases trap heat just like the glass in a greenhouse or in a car)
What is the difference between weather and climate? (sample answer: weather is the daily temperature and precipitation measurements, while climate is a much longer pattern over multiple years)

Drawing of the greenhouse effect – as individuals or in pairs, have students look up the greenhouse effect and draw a diagram to represent it; share out with the class

Optional: figure out students’ beliefs about global warming using the Yale Six Americas Survey (students answer a series of questions and at the end they are given one of the following categories: alarmed, concerned, cautious, disengaged, doubtful, dismissive).

Lesson 2: Searching for and evaluating evidence

Compare different data sources and assess their credibility
Temperature
Precipitation
Storm surge
Ask the students to think about what types of claims they can make about climate change using the data they found (Sample claims: human activity is causing global warming or sea-level rise in the next fifty years will affect coastal cities like Amsterdam, Hong Kong, or New Orleans).

Lesson 3: Writing an argument using evidence

Claim – an inference or a statement that answers a question
Evidence – an outside source of information that supports the claim, often drawn from selected data
Reasoning – the justification/support for the claim; what connects the evidence with the claim
Extending arguments – have students exchange papers and notice the strengths of the other arguments they are reading (can do multiple cycles of reading); ask students to go back to their original argument and expand it with more evidence and/or more justification for why the evidence supports the claim
Anticipate Rebuttals – ask students to think and write about any weaknesses in their own argument

Lesson 4: Argumentation discussion

rebuttal – challenges a component of someone’s argument – for example, a challenge to the evidence used in the original argument
counterargument – a whole new argument that challenges the original argument
respect group members and their ideas
wait for group members to finish their turns before speaking
be mindful of your own contributions to the discussion (try not to take over the whole discussion so others can contribute too; conversely, if you didn’t already talk, find a way to bring in a new argument, expand on an existing argument, or challenge another argument)
Debate/discussion – In table groups have students share their arguments and practice rebuttals and counterarguments
Whole-group reflection – ask students to share key points from their discussion

Lesson 5: Argumentation in action case study

Mumbai, india case study.

Rishi is a thirteen year old boy who attends the Gayak Rafi Nagar Urdu Municipal school in Mumbai. There is a massive landfill called Deonar right across from his school. Every day 4,000 tons of waste are piled on top of the existing garbage spanning 132 hectares (roughly half a square mile). Rishi ventures out to the landfill after school to look for materials that he can later trade for a little bit of extra money to help his family. He feels lucky that he gets to go to school during the day; others are not so lucky. One of his friends, Aamir, had to stop going to school and work full time after his dad got injured. They often meet to chat while they dig through the garbage with sticks. Occasionally, they find books in okay shape, which aren’t worth anything in trade, but to them they are valuable.

One day Rishi was out to the market with his mom and saw the sky darken with a heavy smoke that blocked out the sun. They both hurried home and found out there was a state of emergency and the schools closed for two days. It took many days to put out the fire at Deonar. He heard his dad say that the fire was so bad that it could be seen from space. He wonders what it would be like to see Mumbai from up there. Some days he wishes the government would close down Deonar and clean it up. Other days he wonders what would happen to all the people that depend on it to live if the city shuts down Deonar.

Mumbai is one of the coastal cities that are considered vulnerable with increasing global temperature and sea level rise. The urban poor are most affected by climate change. Their shelter could be wiped out by a tropical storm and rebuilding would be very difficult.

Write a letter to a public official who may be able to influence policy in Mumbai.

What would you recommend they do? Should they close Deonar? What can they do to reduce air pollution in the city and prepare for possible storms? Remember to use evidence in your argument.

Differentiated Instruction

For visual learners – use diagrams, encourage students to map out their arguments prior to writing them
For auditory learners – use the lines of evidence video
For ESL students – provide them with a variety of greenhouse gases diagrams, allow for a more flexible argument format and focus on general meaning-making – ex. using arrows to connect their sources of evidence to claims
For advanced learners – ask them to search through larger data sets and make comparisons between data from different sources; they can also research environmental policies and why they stalled out in congress
For learners that need more support – print out excerpts from articles; pinpoint the main ideas to help with the research; help students connect their evidence with their claims; consider allowing students to work in pairs to accomplish the writing task

Argument write-up – check that students’ arguments contain claims supported by evidence and reasoning and that they thought about possible weaknesses in their own arguments.

Case study letter – check that students included evidence in their letter.

Greta Thunberg’s Climate Change Speech at the 2019 UN Climate Action Summit

Leonardo dicaprio’s climate change speech at the 2014 un climate summit, yeb sano’s climate change speech at the united nations climate summit in warsaw, greta thunberg’s speech at houses of parliament.

In September 2019 climate activist Greta Thunberg addressed the U.N.’s Climate Action Summit in New York City with this inspiring climate change speech:

Here’s the full transcript of Greta Thunberg’s climate change speech. It begins with Greta’s response to a question about the message she has for world leaders.

My message is that we’ll be watching you.

This is all wrong. I shouldn’t be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope. How dare you!

You have stolen my dreams and my childhood with your empty words. And yet I’m one of the lucky ones. People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction, and all you can talk about is money and fairy tales of eternal economic growth. How dare you!

For more than 30 years, the science has been crystal clear. How dare you continue to look away and come here saying that you’re doing enough when the politics and solutions needed are still nowhere in sight.

You say you hear us and that you understand the urgency. But no matter how sad and angry I am, I do not want to believe that. Because if you really understood the situation and still kept on failing to act, then you would be evil. And that I refuse to believe.

The popular idea of cutting our emissions in half in 10 years only gives us a 50% chance of staying below 1.5°C, and the risk of setting off irreversible chain reactions beyond human control.

Fifty per cent may be acceptable to you. But those numbers do not include tipping points, most feedback loops, additional warming hidden by toxic air pollution or the aspects of equity and climate justice. They also rely on my generation sucking hundreds of billions of tons of your CO 2 out of the air with technologies that barely exist.

So a 50% risk is simply not acceptable to us — we who have to live with the consequences.

To have a 67% chance of staying below a 1.5°C global temperature rise – the best odds given by the Intergovernmental Panel on Climate Change – the world had 420 gigatons of CO 2 left to emit back on January 1st, 2018. Today that figure is already down to less than 350 gigatons.

How dare you pretend that this can be solved with just ‘business as usual’ and some technical solutions? With today’s emissions levels, that remaining CO 2 budget will be entirely gone within less than 8 and a half years.

There will not be any solutions or plans presented in line with these figures here today, because these numbers are too uncomfortable. And you are still not mature enough to tell it like it is.

You are failing us. But the young people are starting to understand your betrayal. The eyes of all future generations are upon you. And if you choose to fail us, I say: We will never forgive you.

We will not let you get away with this. Right here, right now is where we draw the line. The world is waking up. And change is coming, whether you like it or not.

Leonardo DiCaprio gave an impassioned climate change speech at the 2014 UN Climate Summit. Watch it now:

Here’s a transcript of Leonardo DiCaprio’s climate change speech in case you’re looking to quote any part of it.

Thank you, Mr Secretary General, your excellencies, ladies and gentleman, and distinguished guests. I’m honoured to be here today, I stand before you not as an expert but as a concerned citizen. One of the 400,000 people who marched in the streets of New York on Sunday, and the billions of others around the world who want to solve our climate crisis.

As an actor, I pretend for a living. I play fictitious characters often solving fictitious problems.

I believe humankind has looked at climate change in that same way. As if it were fiction, happening to someone else’s planet, as if pretending that climate change wasn’t real would somehow make it go away.

But I think we know better than that. Every week, we’re seeing new and undeniable climate events, evidence that accelerated climate change is here now . We know that droughts are intensifying. Our oceans are warming and acidifying, with methane plumes rising up from beneath the ocean floor. We are seeing extreme weather events, increased temperatures, and the West Antarctic and Greenland ice sheets melting at unprecedented rates, decades ahead of scientific projections.

None of this is rhetoric, and none of it is hysteria. It is fact. The scientific community knows it. Industry and governments know it. Even the United States military knows it. The chief of the US Navy’s Pacific Command, Admiral Samuel Locklear, recently said that climate change is our single greatest security threat.

My friends, this body – perhaps more than any other gathering in human history – now faces that difficult task. You can make history or be vilified by it.

To be clear, this is not about just telling people to change their light bulbs or to buy a hybrid car. This disaster has grown BEYOND the choices that individuals make. This is now about our industries, and governments around the world taking decisive, large-scale action.

I am not a scientist, but I don’t need to be. Because the world’s scientific community has spoken, and they have given us our prognosis. If we do not act together, we will surely perish.

Now is our moment for action.

We need to put a price tag on carbon emissions and eliminate government subsidies for coal, gas, and oil companies. We need to end the free ride that industrial polluters have been given in the name of a free-market economy. They don’t deserve our tax dollars, they deserve our scrutiny. For the economy itself will die if our ecosystems collapse.

The good news is that renewable energy is not only achievable but good economic policy. New research shows that by 2050 clean, renewable energy could supply 100% of the world’s energy needs using existing technologies, and it would create millions of jobs.

This is not a partisan debate; it is a human one. Clean air and water, and a livable climate are inalienable human rights. And solving this crisis is not a question of politics. It is our moral obligation – if, admittedly, a daunting one.

We only get one planet. Humankind must become accountable on a massive scale for the wanton destruction of our collective home. Protecting our future on this planet depends on the conscious evolution of our species.

This is the most urgent of times, and the most urgent of messages.

Honoured delegates, leaders of the world, I pretend for a living. But you do not. The people made their voices heard on Sunday around the world and the momentum will not stop. And now it’s YOUR turn, the time to answer the greatest challenge of our existence on this planet is now.

I beg you to face it with courage. And honesty. Thank you.

The Philippines’ lead negotiator Yeb Sano addressed the opening session of the UN climate summit in Warsaw in November 2013. In this emotional and powerful climate change speech he called for urgent action to prevent a repeat of the devastating storm that hit parts of the Philippines:

Transcript of Yeb’s Climate Change Speech

Here’s a transcript of Yeb’s climate change speech:

Mr President, I have the honour to speak on behalf of the resilient people of the Republic of the Philippines.

At the onset, allow me to fully associate my delegation with the statement made by the distinguished Ambassador of the Republic of Fiji, on behalf of G77 and China as well as the statement made by Nicaragua on behalf of the Like-Minded Developing Countries.

First and foremost, the people of the Philippines, and our delegation here for the United Nations Climate Change Convention’s 19 th Conference of the Parties here in Warsaw, from the bottom of our hearts, thank you for your expression of sympathy to my country in the face of this national difficulty.

In the midst of this tragedy, the delegation of the Philippines is comforted by the warm hospitality of Poland, with your people offering us warm smiles everywhere we go. Hotel staff and people on the streets, volunteers and personnel within the National Stadium have warmly offered us kind words of sympathy. So, thank you Poland.

The arrangements you have made for this COP is also most excellent and we highly appreciate the tremendous effort you have put into the preparations for this important gathering.

We also thank all of you, friends and colleagues in this hall and from all corners of the world as you stand beside us in this difficult time.

I thank all countries and governments who have extended your solidarity and for offering assistance to the Philippines.

I thank the youth present here and the billions of young people around the world who stand steadfastly behind my delegation and who are watching us shape their future.

I thank civil society, both who are working on the ground as we race against time in the hardest-hit areas, and those who are here in Warsaw prodding us to have a sense of urgency and ambition.

We are deeply moved by this manifestation of human solidarity. This outpouring of support proves to us that as a human race, we can unite; that as a species, we care.

It was barely 11 months ago in Doha when my delegation appealed to the world… to open our eyes to the stark reality that we face… as then we confronted a catastrophic storm that resulted in the costliest disaster in Philippine history.

Less than a year hence, we cannot imagine that a disaster much bigger would come. With an apparent cruel twist of fate, my country is being tested by this hellstorm called Super Typhoon Haiyan, which has been described by experts as the strongest typhoon that has ever made landfall in the course of recorded human history.

It was so strong that if there was a Category 6, it would have fallen squarely in that box. Up to this hour, we remain uncertain as to the full extent of the devastation, as information trickles in an agonisingly slow manner because electricity lines and communication lines have been cut off and may take a while before these are restored.

The initial assessment shows that Haiyan left a wake of massive devastation that is unprecedented, unthinkable, and horrific, affecting 2/3 of the Philippines, with about half a million people now rendered homeless, and with scenes reminiscent of the aftermath of a tsunami, with a vast wasteland of mud and debris and dead bodies.

According to satellite estimates, the US National Oceanic and Atmospheric Administration also estimated that Haiyan achieved a minimum pressure between around 860 mbar (hPa; 25.34 inHg) and the Joint Typhoon Warning Center estimated Haiyan to have attained one-minute sustained winds of 315 km/h (195 mph) and gusts up to 378 km/h (235 mph) making it the strongest typhoon in modern recorded history.

Despite the massive efforts that my country had exerted in preparing for the onslaught of this monster of a storm, it was just a force too powerful, and even as a nation familiar with storms, Super Typhoon Haiyan was nothing we have ever experienced before, or perhaps nothing that any country has every experienced before.

The picture in the aftermath is ever so slowly coming into clearer focus. The devastation is colossal. And as if this is not enough, another storm is brewing again in the warm waters of the western Pacific. I shudder at the thought of another typhoon hitting the same places where people have not yet even managed to begin standing up.

To anyone who continues to deny the reality that is climate change, I dare you to get off your ivory tower and away from the comfort of your armchair.

I dare you to go to the islands of the Pacific, the islands of the Caribbean and the islands of the Indian Ocean and see the impacts of rising sea levels; to the mountainous regions of the Himalayas and the Andes to see communities confronting glacial floods, to the Arctic where communities grapple with the fast dwindling polar ice caps, to the large deltas of the Mekong, the Ganges, the Amazon, and the Nile where lives and livelihoods are drowned, to the hills of Central America that confront similar monstrous hurricanes, to the vast savannahs of Africa where climate change has likewise become a matter of life and death as food and water becomes scarce.

Not to forget the massive hurricanes in the Gulf of Mexico and the eastern seaboard of North America. And if that is not enough, you may want to pay a visit to the Philippines right now.

The science has given us a picture that has become much more in focus. The IPCC report on climate change and extreme events underscored the risks associated with changes in the patterns as well as the frequency of extreme weather events.

Science tells us that simply, climate change will mean more intense tropical storms. As the Earth warms up, that would include the oceans. The energy that is stored in the waters off the Philippines will increase the intensity of typhoons and the trend we now see is that more destructive storms will be the new norm.

This will have profound implications on many of our communities, especially who struggle against the twin challenges of the development crisis and the climate change crisis. Typhoons such as Yolanda (Haiyan) and its impacts represent a sobering reminder to the international community that we cannot afford to procrastinate on climate action. Warsaw must deliver on enhancing ambition and should muster the political will to address climate change.

In Doha, we asked, “If not us then who? If not now, then when? If not here, then where?” (borrowed from Philippine student leader Ditto Sarmiento during Martial Law). It may have fell on deaf ears. But here in Warsaw, we may very well ask these same forthright questions. “If not us, then who? If not now, then when? If not here in Warsaw, where?”

What my country is going through as a result of this extreme climate event is madness. The climate crisis is madness.

We can stop this madness. Right here in Warsaw.

It is the 19 th COP, but we might as well stop counting because my country refuses to accept that a COP30 or a COP40 will be needed to solve climate change.

And because it seems that despite the significant gains we have had since the UNFCCC was born, 20 years hence we continue to fail in fulfilling the ultimate objective of the Convention.

Now, we find ourselves in a situation where we have to ask ourselves – can we ever attain the objective set out in Article 2 – which is to prevent dangerous anthropogenic interference with the climate system? By failing to meet the objective of the Convention, we may have ratified the doom of vulnerable countries.

And if we have failed to meet the objective of the Convention, we have to confront the issue of loss and damage.

Loss and damage from climate change is a reality today across the world. Developed country emissions reduction targets are dangerously low and must be raised immediately. But even if they were in line with the demand of reducing 40-50% below 1990 levels, we would still have locked-in climate change and would still need to address the issue of loss and damage.

We find ourselves at a critical juncture and the situation is such that even the most ambitious emissions reductions by developed countries, who should have been taking the lead in combatting climate change in the past two decades, will not be enough to avert the crisis.

It is now too late, too late to talk about the world being able to rely on Annex I countries to solve the climate crisis. We have entered a new era that demands global solidarity in order to fight climate change and ensure that the pursuit of sustainable human development remains at the fore of the global community’s efforts. This is why means of implementation for developing countries is ever more crucial.

It was the Secretary-general of the UN Conference on Environment and Development, Earth Summit, Rio de Janeiro, 1992, Maurice Strong who said that “History reminds us that what is not possible today, may be inevitable tomorrow.”

We cannot sit and stay helpless staring at this international climate stalemate. It is now time to take action. We need an emergency climate pathway.

I speak for my delegation. But more than that, I speak for the countless people who will no longer be able to speak for themselves after perishing from the storm. I also speak for those who have been orphaned by this tragedy. I also speak for the people now racing against time to save survivors and alleviate the suffering of the people affected by the disaster.

We can take drastic action now to ensure that we prevent a future where super typhoons are a way of life. Because we refuse, as a nation, to accept a future where super typhoons like Haiyan become a fact of life. We refuse to accept that running away from storms, evacuating our families, suffering the devastation and misery, having to count our dead, become a way of life. We simply refuse to.

We must stop calling events like these as natural disasters. It is not natural when people continue to struggle to eradicate poverty and pursue development and get battered by the onslaught of a monster storm now considered as the strongest storm ever to hit land. It is not natural when science already tells us that global warming will induce more intense storms. It is not natural when the human species has already profoundly changed the climate.

Disasters are never natural. They are the intersection of factors other than physical. They are the accumulation of the constant breach of economic, social, and environmental thresholds.

Most of the time disasters are a result of inequity and the poorest people of the world are at greatest risk because of their vulnerability and decades of maldevelopment, which I must assert is connected to the kind of pursuit of economic growth that dominates the world. The same kind of pursuit of so-called economic growth and unsustainable consumption that has altered the climate system.

Now, if you will allow me, to speak on a more personal note.

Super Typhoon Haiyan made landfall in my family’s hometown and the devastation is staggering. I struggle to find words even for the images that we see from the news coverage. I struggle to find words to describe how I feel about the losses and damages we have suffered from this cataclysm.

Up to this hour, I agonize while waiting for word as to the fate of my very own relatives. What gives me renewed strength and great relief was when my brother succeeded in communicating with us that he has survived the onslaught. In the last two days, he has been gathering bodies of the dead with his own two hands. He is hungry and weary as food supplies find it difficult to arrive in the hardest-hit areas.

We call on this COP to pursue work until the most meaningful outcome is in sight. Until concrete pledges have been made to ensure mobilisation of resources for the Green Climate Fund. Until the promise of the establishment of a loss and damage mechanism has been fulfilled. Until there is assurance on finance for adaptation. Until concrete pathways for reaching the committed 100 billion dollars have been made. Until we see real ambition on stabilizing greenhouse gas concentrations. We must put the money where our mouths are.

This process under the UNFCCC has been called many names. It has been called a farce. It has been called an annual carbon-intensive gathering of useless frequent flyers. It has been called many names. But it has also been called “The Project To Save The Planet”. It has been called “Saving Tomorrow Today”. We can fix this. We can stop this madness. Right now. Right here, in the middle of this football field.

I call on you to lead us. And let Poland be forever known as the place we truly cared to stop this madness. Can humanity rise to the occasion? I still believe we can.

Finally, in April 2019, Greta spoke at the Houses of Parliament in the UK. Here she gave this powerful climate change speech to the UK’s political leaders:

Transcript of Greta’s Climate Change Speech

Here is the full transcript of Greta’s climate change speech:

My name is Greta Thunberg. I am 16 years old. I come from Sweden. And I speak on behalf of future generations.

I know many of you don’t want to listen to us – you say we are just children. But we’re only repeating the message of the united climate science.

Many of you appear concerned that we are wasting valuable lesson time, but I assure you we will go back to school the moment you start listening to science and give us a future. Is that really too much to ask?

In the year 2030, I will be 26 years old. My little sister Beata will be 23. Just like many of your own children or grandchildren. That is a great age, we have been told. When you have all of your life ahead of you. But I am not so sure it will be that great for us.

I was fortunate to be born in a time and place where everyone told us to dream big. I could become whatever I wanted to. I could live wherever I wanted to. People like me had everything we needed and more. Things our grandparents could not even dream of. We had everything we could ever wish for and yet now we may have nothing.

Now we probably don’t even have a future anymore.

Because that future was sold so that a small number of people could make unimaginable amounts of money. It was stolen from us every time you said that the sky was the limit and that you only live once.

You lied to us. You gave us false hope. You told us that the future was something to look forward to. And the saddest thing is that most children are not even aware of the fate that awaits us. We will not understand it until it’s too late. And yet we are the lucky ones. Those who will be affected the hardest are already suffering the consequences. But their voices are not heard.

Is my microphone on? Can you hear me?

Around the year 2030, 10 years 252 days and 10 hours away from now, we will be in a position where we set off an irreversible chain reaction beyond human control, that will most likely lead to the end of our civilisation as we know it. That is unless, in that time, permanent and unprecedented changes in all aspects of society have taken place, including a reduction of CO 2 emissions by at least 50%.

And please note that these calculations are depending on inventions that have not yet been invented at scale, inventions that are supposed to clear the atmosphere of astronomical amounts of carbon dioxide.

Furthermore, these calculations do not include unforeseen tipping points and feedback loops like the extremely powerful methane gas escaping from rapidly thawing arctic permafrost.

Nor do these scientific calculations include already locked-in warming hidden by toxic air pollution. Nor the aspect of equity – or climate justice – clearly stated throughout the Paris Agreement, which is absolutely necessary to make it work on a global scale.

We must also bear in mind that these are just calculations. Estimations. That means that these “points of no return” may occur a bit sooner or later than 2030. No one can know for sure. We can, however, be certain that they will occur approximately in these timeframes because these calculations are not opinions or wild guesses.

These projections are backed up by scientific facts, concluded by all nations through the IPCC. Nearly every single major national scientific body around the world unreservedly supports the work and findings of the IPCC.

Did you hear what I just said? Is my English OK? Is the microphone on? Because I’m beginning to wonder.

During the last six months, I have travelled around Europe for hundreds of hours in trains, electric cars, and buses, repeating these life-changing words over and over again. But no one seems to be talking about it, and nothing has changed. In fact, the emissions are still rising.

When I have been travelling around to speak in different countries, I am always offered help to write about the specific climate policies in specific countries. But that is not really necessary. Because the basic problem is the same everywhere. And the basic problem is that basically nothing is being done to halt – or even slow – climate and ecological breakdown, despite all the beautiful words and promises.

The UK is, however, very special. Not only for its mind-blowing historical carbon debt but also for its current, very creative, carbon accounting.

Since 1990 the UK has achieved a 37% reduction of its territorial CO 2 emissions, according to the Global Carbon Project. And that does sound very impressive. But these numbers do not include emissions from aviation, shipping, and those associated with imports and exports. If these numbers are included the reduction is around 10% since 1990 – or an average of 0.4% a year, according to Tyndall Manchester. And the main reason for this reduction is not a consequence of climate policies, but rather a 2001 EU directive on air quality that essentially forced the UK to close down its very old and extremely dirty coal power plants and replace them with less dirty gas power stations. And switching from one disastrous energy source to a slightly less disastrous one will of course result in a lowering of emissions.

But perhaps the most dangerous misconception about the climate crisis is that we have to “lower” our emissions. Because that is far from enough.

Our emissions have to stop if we are to stay below 1.5-2 ° C of warming. The “lowering of emissions” is of course necessary but it is only the beginning of a fast process that must lead to a stop within a couple of decades or less. And by “stop” I mean net-zero – and then quickly on to negative figures. That rules out most of today’s politics.

The fact that we are speaking of “lowering” instead of “stopping” emissions is perhaps the greatest force behind the continuing business as usual. The UK’s active current support of new exploitation of fossil fuels – for example, the UK shale gas fracking industry, the expansion of its North Sea oil and gas fields, the expansion of airports as well as the planning permission for a brand new coal mine – is beyond absurd.

This ongoing irresponsible behaviour will no doubt be remembered in history as one of the greatest failures of humankind.

People always tell me and the other millions of school strikers that we should be proud of ourselves for what we have accomplished. But the only thing that we need to look at is the emission curve. And I’m sorry, but it’s still rising. That curve is the only thing we should look at.

Every time we make a decision we should ask ourselves; how will this decision affect that curve? We should no longer measure our wealth and success in the graph that shows economic growth, but in the curve that shows the emissions of greenhouse gases. We should no longer only ask: “Have we got enough money to go through with this?” but also: “Have we got enough of the carbon budget to spare to go through with this?” That should and must become the centre of our new currency.

Many people say that we don’t have any solutions to the climate crisis. And they are right. Because how could we? How do you “solve” the greatest crisis that humanity has ever faced? How do you “solve” a war? How do you “solve” going to the moon for the first time? How do you “solve” inventing new inventions?

The climate crisis is both the easiest and the hardest issue we have ever faced. The easiest because we know what we must do. We must stop the emissions of greenhouse gases. The hardest because our current economics are still totally dependent on burning fossil fuels, and thereby destroying ecosystems in order to create everlasting economic growth.

“So, exactly how do we solve that?” you ask us – the schoolchildren striking for the climate.

And we say: “No one knows for sure. But we have to stop burning fossil fuels and restore nature and many other things that we may not have quite figured out yet.”

Then you say: “That’s not an answer!”

So we say: “We have to start treating the crisis like a crisis – and act even if we don’t have all the solutions.”

“That’s still not an answer,” you say.

Then we start talking about circular economy and rewilding nature and the need for a just transition. Then you don’t understand what we are talking about.

We say that all those solutions needed are not known to anyone and therefore we must unite behind the science and find them together along the way. But you do not listen to that. Because those answers are for solving a crisis that most of you don’t even fully understand. Or don’t want to understand.

You don’t listen to the science because you are only interested in solutions that will enable you to carry on like before. Like now. And those answers don’t exist anymore. Because you did not act in time.

Avoiding climate breakdown will require cathedral thinking. We must lay the foundation while we may not know exactly how to build the ceiling.

Sometimes we just simply have to find a way. The moment we decide to fulfil something, we can do anything. And I’m sure that the moment we start behaving as if we were in an emergency, we can avoid climate and ecological catastrophe. Humans are very adaptable: we can still fix this. But the opportunity to do so will not last for long. We must start today. We have no more excuses.

We children are not sacrificing our education and our childhood for you to tell us what you consider is politically possible in the society that you have created. We have not taken to the streets for you to take selfies with us, and tell us that you really admire what we do.

We children are doing this to wake the adults up. We children are doing this for you to put your differences aside and start acting as you would in a crisis. We children are doing this because we want our hopes and dreams back.

I hope my microphone was on. I hope you could all hear me.

Hopefully, these climate change speeches will encourage you to take action in your local community. If you need more inspiration then head to my post on the best TED Talks on climate change , my guide to the best YouTube videos on climate change , and the sustainability poems to inspire you.

You Asked: What’s the Best Way To Talk About Climate Change?

This story was published as part of our Climate Week NYC coverage. Learn more about Climate Week, read our other stories , and check out our upcoming events .

More Americans today are worried about climate change than ever before. From 2014 to 2020, the proportion of people who said they felt “alarmed” by global warming nearly tripled, according to research from the Yale Program on Climate Change Communication. But while public awareness for climate change is at an all-time high, dinner tables and debate stages can still feel boobytrapped with uncomfortable conversations. As part of State of the Planet’s “You Asked” series, Columbia scientists, journalists, and content creators spoke to why that is and how, through thoughtful climate communication, it doesn’t have to be.

The Evolution of Climate Communication

Climate scientist and Columbia Climate School professor Kate Marvel remembers when the main story about climate change had to do with whether or not it existed. Experts not unlike herself were pitted against skeptics on live television with little time for well-meaning discussion. The relatively few stories that did uplift climate science focused on what was happening in the natural world; for mainstream publications—and the majority of their readers—that meant climate change was synonymous with polar bears trapped on melting icebergs or rainforests burning in the Amazon.

Andrew Revkin was an environmental reporter with The New York Times for over 15 years before joining the Earth Institute as the director of the Initiative on Communication and Sustainability. He said the “newsroom norm” of prioritizing what had happened that day made it difficult for issues with incremental developments and long-term time horizons to get top billing. It is only in the last handful of years, he noted, that climate change has begun to “infuse itself into other coverage,” with reporters writing about its impact on other pressing social issues such as public health and racial justice.

At the same time, climate solutions have become more visible and scalable, resulting in coverage that considershow the crisis can be mitigated, rather than just its consequences. Sabine Marx, former managing director of Columbia’s Center for Research on Environmental Decisions, said this shift has offered a psychological advantage in how the threat of climate change is communicated. “If I know there are steps that I can take towards actionable solutions, then I am much more likely to accept that there’s a problem,” she explained.

Climate communication has also been supported by the proliferation of new forms of media. Sustainable Development student Lauren Ritchie , for example, founded the online platform The EcoJustice Project to make climate education and action more accessible to her generation.

“Gen Z is eager to learn and trying to get involved,” said Ritchie. “Most of the time, I’m making content based on what I would want to consume.”

Through social media features like Instagram Live, Ritchie provides her tens of thousands of followers with the opportunity to hear firsthand from people experiencing and responding to climate change in their communities.

How To Talk About Climate Change

Whether it is in person, in print, or online, climate communication often begins where it ends—with the audience. Marx explained that the experiences and values of a person inherently shape the way that they choose to engage with climate change, if at all. As a result, what resonates with a financial investor in New England might not be what resonates with a farmer in the Southeast.

“Knowing your audience will allow you to get beyond the information deficit so that you can look at filling a motivation deficit,” said Marx.

With no shortage of prospective audiences, climate communicators are constantly adapting the way that they frame the issue, a process that Marvel has found to be really empowering. “I don’t like feeling like a robot,” she said. “I think if you decide that there’s only one way to communicate about this, and you have to say the same thing over and over, then you’re going to burn out really quickly.”

Journalist Brian Kahn will use any combination of analogies, examples, and recent climate events in his work to connect with his readers—including the ones who send him hate mail. “As long as they’re not threatening my life, I’ll usually respond,” he said. “There’s a surprising amount of common ground between folks where you might not expect it.”

While finding common ground does not always equate to changing someone’s mind, Marvel noted that it is often the “human conversations without ulterior motives” that are the most productive. “When I talk about climate change, I want other people to understand this thing that’s really important to me,” she said, “and I want to learn from other people.”

It is a strategy that Marx refers to as “leading to ” climate change, rather than “leading with ” climate change. By starting with what is relatable—raising kids, owning a home, enjoying long walks on the beach—the impacts of climate change can be tethered to the shared reality of what is at stake. “We want to open the door with something that is meaningful to people, something that they care about,” she said.

The Future of Climate Communication

Given that climate communication has changed so much in the last two decades, it can be difficult to predict what will come next for the field as a whole. For Revkin, the future of climate communication will involve convening more stakeholders for in-depth conversations rather than writing for traditional media outlets.

“Climate and sustainability communication is different from telling another good story,” he said. “It’s getting brains into a place and having them think about something they might not otherwise, to collaborate on something that they can do more effectively together than alone.”

Through his “Sustain What?” webcast series, Revkin has already hosted a wide variety of experts to discuss issues ranging from global ecological restoration to the future of nuclear energy . In the last year and a half, he has recorded over 220 episodes that have engaged an estimated one million listeners.

The creation of new shared spaces like the “Sustain What?” webcast series can also function to champion greater diversity in climate discourse—something that Ritchie, Marvel, and Kahn stressed is desperately needed moving forward. “There is so much nuance to climate change,” said Ritchie, “and yet we tend to look at it through this privileged, white lens.”

Marvel agreed. “It’s an existential problem if climate communication is a monolith,” she said. “No one person or group of people is going to be able to talk to all communities, so we need to uplift diverse voices.”

Perhaps then the most important part of climate communication is that it keeps happening in more places with more people, especially in the face of what Kahn referred to as an “epidemic of climate silence” in the United States and around the world.

“People should not be afraid to talk about this stuff,” he said. “Having these conversations—even if they feel hard—is the first step to actually acting, passing climate policy, and getting this work done.”

Essay on Global Warming

Updated on
Apr 27, 2024

Being able to write an essay is an integral part of mastering any language. Essays form an integral part of many academic and scholastic exams like the SAT, and UPSC amongst many others. It is a crucial evaluative part of English proficiency tests as well like IELTS, TOEFL, etc. Major essays are meant to emphasize public issues of concern that can have significant consequences on the world. To understand the concept of Global Warming and its causes and effects, we must first examine the many factors that influence the planet’s temperature and what this implies for the world’s future. Here’s an unbiased look at the essay on Global Warming and other essential related topics.

Short Essay on Global Warming and Climate Change?

Since the industrial and scientific revolutions, Earth’s resources have been gradually depleted. Furthermore, the start of the world’s population’s exponential expansion is particularly hard on the environment. Simply put, as the population’s need for consumption grows, so does the use of natural resources , as well as the waste generated by that consumption.

Climate change has been one of the most significant long-term consequences of this. Climate change is more than just the rise or fall of global temperatures; it also affects rain cycles, wind patterns, cyclone frequencies, sea levels, and other factors. It has an impact on all major life groupings on the planet.

What is Global Warming?

Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century, primarily due to the greenhouse gases released by people burning fossil fuels . The greenhouse gases consist of methane, nitrous oxide, ozone, carbon dioxide, water vapour, and chlorofluorocarbons. The weather prediction has been becoming more complex with every passing year, with seasons more indistinguishable, and the general temperatures hotter.

The number of hurricanes, cyclones, droughts, floods, etc., has risen steadily since the onset of the 21st century. The supervillain behind all these changes is Global Warming. The name is quite self-explanatory; it means the rise in the temperature of the Earth.

What are the Causes of Global Warming?

According to recent studies, many scientists believe the following are the primary four causes of global warming:

Deforestation
Greenhouse emissions
Carbon emissions per capita

Extreme global warming is causing natural disasters , which can be seen all around us. One of the causes of global warming is the extreme release of greenhouse gases that become trapped on the earth’s surface, causing the temperature to rise. Similarly, volcanoes contribute to global warming by spewing excessive CO2 into the atmosphere.

The increase in population is one of the major causes of Global Warming. This increase in population also leads to increased air pollution . Automobiles emit a lot of CO2, which remains in the atmosphere. This increase in population is also causing deforestation, which contributes to global warming.

The earth’s surface emits energy into the atmosphere in the form of heat, keeping the balance with the incoming energy. Global warming depletes the ozone layer, bringing about the end of the world. There is a clear indication that increased global warming will result in the extinction of all life on Earth’s surface.

Solutions for Global Warming

Of course, industries and multinational conglomerates emit more carbon than the average citizen. Nonetheless, activism and community effort are the only viable ways to slow the worsening effects of global warming. Furthermore, at the state or government level, world leaders must develop concrete plans and step-by-step programmes to ensure that no further harm is done to the environment in general.

Although we are almost too late to slow the rate of global warming, finding the right solution is critical. Everyone, from individuals to governments, must work together to find a solution to Global Warming. Some of the factors to consider are pollution control, population growth, and the use of natural resources.

One very important contribution you can make is to reduce your use of plastic. Plastic is the primary cause of global warming, and recycling it takes years. Another factor to consider is deforestation, which will aid in the control of global warming. More tree planting should be encouraged to green the environment. Certain rules should also govern industrialization. Building industries in green zones that affect plants and species should be prohibited.

Effects of Global Warming

Global warming is a real problem that many people want to disprove to gain political advantage. However, as global citizens, we must ensure that only the truth is presented in the media.

This decade has seen a significant impact from global warming. The two most common phenomena observed are glacier retreat and arctic shrinkage. Glaciers are rapidly melting. These are clear manifestations of climate change.

Another significant effect of global warming is the rise in sea level. Flooding is occurring in low-lying areas as a result of sea-level rise. Many countries have experienced extreme weather conditions. Every year, we have unusually heavy rain, extreme heat and cold, wildfires, and other natural disasters.

Similarly, as global warming continues, marine life is being severely impacted. This is causing the extinction of marine species as well as other problems. Furthermore, changes are expected in coral reefs, which will face extinction in the coming years. These effects will intensify in the coming years, effectively halting species expansion. Furthermore, humans will eventually feel the negative effects of Global Warming.

Essay on Global Warming Paragraph in 100 – 150 words

Global Warming is caused by the increase of carbon dioxide levels in the earth’s atmosphere and is a result of human activities that have been causing harm to our environment for the past few centuries now. Global Warming is something that can’t be ignored and steps have to be taken to tackle the situation globally. The average temperature is constantly rising by 1.5 degrees Celsius over the last few years.

The best method to prevent future damage to the earth, cutting down more forests should be banned and Afforestation should be encouraged. Start by planting trees near your homes and offices, participate in events, and teach the importance of planting trees. It is impossible to undo the damage but it is possible to stop further harm.

Essay on Global Warming in 250 Words

Over a long period, it is observed that the temperature of the earth is increasing. This affected wildlife, animals, humans, and every living organism on earth. Glaciers have been melting, and many countries have started water shortages, flooding, and erosion and all this is because of global warming.

No one can be blamed for global warming except for humans. Human activities such as gases released from power plants, transportation, and deforestation have increased gases such as carbon dioxide, CFCs, and other pollutants in the earth’s atmosphere. The main question is how can we control the current situation and build a better world for future generations. It starts with little steps by every individual.

Start using cloth bags made from sustainable materials for all shopping purposes, instead of using high-watt lights use energy-efficient bulbs, switch off the electricity, don’t waste water, abolish deforestation and encourage planting more trees. Shift the use of energy from petroleum or other fossil fuels to wind and solar energy. Instead of throwing out the old clothes donate them to someone so that it is recycled.

Donate old books, don’t waste paper. Above all, spread awareness about global warming. Every little thing a person does towards saving the earth will contribute in big or small amounts. We must learn that 1% effort is better than no effort. Pledge to take care of Mother Nature and speak up about global warming.

Essay on Global Warming in 500 Words

Global warming isn’t a prediction, it is happening! A person denying it or unaware of it is in the most simple terms complicit. Do we have another planet to live on? Unfortunately, we have been bestowed with this one planet only that can sustain life yet over the years we have turned a blind eye to the plight it is in. Global warming is not an abstract concept but a global phenomenon occurring ever so slowly even at this moment. Global Warming is a phenomenon that is occurring every minute resulting in a gradual increase in the Earth’s overall climate. Brought about by greenhouse gases that trap the solar radiation in the atmosphere, global warming can change the entire map of the earth, displacing areas, flooding many countries, and destroying multiple lifeforms. Extreme weather is a direct consequence of global warming but it is not an exhaustive consequence. There are virtually limitless effects of global warming which are all harmful to life on earth. The sea level is increasing by 0.12 inches per year worldwide. This is happening because of the melting of polar ice caps because of global warming. This has increased the frequency of floods in many lowland areas and has caused damage to coral reefs. The Arctic is one of the worst-hit areas affected by global warming. Air quality has been adversely affected and the acidity of the seawater has also increased causing severe damage to marine life forms. Severe natural disasters are brought about by global warming which has had dire effects on life and property. As long as mankind produces greenhouse gases, global warming will continue to accelerate. The consequences are felt at a much smaller scale which will increase to become drastic shortly. The power to save the day lies in the hands of humans, the need is to seize the day. Energy consumption should be reduced on an individual basis. Fuel-efficient cars and other electronics should be encouraged to reduce the wastage of energy sources. This will also improve air quality and reduce the concentration of greenhouse gases in the atmosphere. Global warming is an evil that can only be defeated when fought together. It is better late than never. If we all take steps today, we will have a much brighter future tomorrow. Global warming is the bane of our existence and various policies have come up worldwide to fight it but that is not enough. The actual difference is made when we work at an individual level to fight it. Understanding its import now is crucial before it becomes an irrevocable mistake. Exterminating global warming is of utmost importance and each one of us is as responsible for it as the next.

Essay on Global Warming UPSC

Always hear about global warming everywhere, but do we know what it is? The evil of the worst form, global warming is a phenomenon that can affect life more fatally. Global warming refers to the increase in the earth’s temperature as a result of various human activities. The planet is gradually getting hotter and threatening the existence of lifeforms on it. Despite being relentlessly studied and researched, global warming for the majority of the population remains an abstract concept of science. It is this concept that over the years has culminated in making global warming a stark reality and not a concept covered in books. Global warming is not caused by one sole reason that can be curbed. Multifarious factors cause global warming most of which are a part of an individual’s daily existence. Burning of fuels for cooking, in vehicles, and for other conventional uses, a large amount of greenhouse gases like carbon dioxide, and methane amongst many others is produced which accelerates global warming. Rampant deforestation also results in global warming as lesser green cover results in an increased presence of carbon dioxide in the atmosphere which is a greenhouse gas. Finding a solution to global warming is of immediate importance. Global warming is a phenomenon that has to be fought unitedly. Planting more trees can be the first step that can be taken toward warding off the severe consequences of global warming. Increasing the green cover will result in regulating the carbon cycle. There should be a shift from using nonrenewable energy to renewable energy such as wind or solar energy which causes less pollution and thereby hinder the acceleration of global warming. Reducing energy needs at an individual level and not wasting energy in any form is the most important step to be taken against global warming. The warning bells are tolling to awaken us from the deep slumber of complacency we have slipped into. Humans can fight against nature and it is high time we acknowledged that. With all our scientific progress and technological inventions, fighting off the negative effects of global warming is implausible. We have to remember that we do not inherit the earth from our ancestors but borrow it from our future generations and the responsibility lies on our shoulders to bequeath them a healthy planet for life to exist.

Climate Change and Global Warming Essay

Global Warming and Climate Change are two sides of the same coin. Both are interrelated with each other and are two issues of major concern worldwide. Greenhouse gases released such as carbon dioxide, CFCs, and other pollutants in the earth’s atmosphere cause Global Warming which leads to climate change. Black holes have started to form in the ozone layer that protects the earth from harmful ultraviolet rays.

Human activities have created climate change and global warming. Industrial waste and fumes are the major contributors to global warming.

Another factor affecting is the burning of fossil fuels, deforestation and also one of the reasons for climate change. Global warming has resulted in shrinking mountain glaciers in Antarctica, Greenland, and the Arctic and causing climate change. Switching from the use of fossil fuels to energy sources like wind and solar.

When buying any electronic appliance buy the best quality with energy savings stars. Don’t waste water and encourage rainwater harvesting in your community.

Tips to Write an Essay

When will climate change turn life in the U.S. upside down?

Jump to a section of this essay

What is a dangerous level of climate change, climate change’s impacts will be highly asymmetric, an immediate u.s. climate change threat: an insurance crisis, a second potential immediate u.s. climate change threat: a global food shock, “black swan” and “gray swan” extreme weather events, a “new normal” of extreme weather has not yet arrived, longer-range concerns: global catastrophic risk events, devastating impacts from climate change are accelerating, paleolithic emotions, medieval institutions, and godlike technology, hope for the future via ‘cathedral thinking’.

Although there is a major climate change hurricane approaching, we’re busy throwing a hurricane party , charging up our planetary credit card to pay for the expenses, with little regard to the approaching storm that is already cutting off our escape routes. This great storm will fundamentally rip at the fabric of society, creating chaos and a crisis likely to last for many decades.

The intensifying climate change storm will soon reach a threshold I think of as a category 1 hurricane for humanity — when long-term global warming surpasses 1.5 degrees Celsius above preindustrial temperatures, a value increasingly characterized over the last decade as “dangerous” climate change .

For humanity as a whole, this amount of warming is risky, but not devastating. Global warming is currently at about 1.2-1.3 degrees Celsius above preindustrial temperatures and is likely to cross the 1.5-degree threshold in the late 2020s or early 2030s .

Assuming that we don’t work exceptionally hard to reduce emissions in the next 10 years, the world is expected to reach 2 degrees Celsius of warming between 2045 and 2051. In my estimation, that will be akin to a major category 3 hurricane for humanity — devastating, but not catastrophic.

Allowing global warming to exceed 2.5 degrees Celsius will cause category 4-level damage to civilization — approaching the catastrophic level. And warming in excess of 3 degrees Celsius will likely be a catastrophic category 5-level superstorm of destruction that will crash civilization.

We must take strong action rapidly to rein in our emissions of heat-trapping gases to avoid that outcome — and build great resilience to the extreme climate of the 21st century that we have so foolishly brought upon ourselves.

According to the Carbon Action Tracker (see tweet below), we are on track for 2.7 degrees Celsius of warming; if the nations of the world meet their targets for reducing heat-trapping climate pollution, warming will be limited to 2.1 degrees. There’s a big difference between being hit by a Cat 4 versus a Cat 3, and every tenth of a degree of warming that we prevent will be critical.

Two years on from Glasgow and our warming estimates for government action have barely moved. Governments appear oblivious to the extreme events of the past year, somehow thinking treading water will deal with the flood of impacts? https://t.co/fbM4xY9OJe pic.twitter.com/MekGIeU1Z3 — ClimateActionTracker (@climateactiontr) December 5, 2023

As climate scientist Michael Mann explains in his latest book, “ Our Fragile Moment ,” great climate science communicator Stephen Schneider once said, “The ‘end of the world’ or ‘good for you’ are the two least likely among the spectrum of potential [climate] outcomes.” So forget sci-fi depictions of planetary apocalypse. That will not be our long-term climate change fate.

But the impacts of climate change will be apocalyptic for many nations and people — particularly those that are not rich and White. People and communities with the least resources tend to be the first and hardest hit by climate change , not only because poorer people and communities are inherently more vulnerable to the impacts of any disaster, but also because the extremes induced by climate change tend to be worse in the tropics and subtropics, home to many poor nations.

In the U.S., climate change has already turned life upside down for numerous communities. For example, in North Carolina, the financially strapped, Black-majority towns of Fair Bluff and Princeville are in danger of abandonment from hurricane-related flooding (from Hurricane Floyd in 1999, Matthew in 2016, and Florence in 2018). Seven Springs, North Carolina (population 207 in 1960, now just 55) is largely abandoned.

Climate change was a key contributor to these floods; a 2021 study found that about one-third of the cost of major U.S. flood events since 1988, totaling $79 billion, could be attributed to climate change. And for the town of Paradise, California — utterly destroyed by the devastating Camp Fire of 2018, which killed 85 and caused over $16 billion in damage — climate change has been apocalyptic.

In the U.S., the most likely major economic disruption from climate change over the next few years might well be a collapse of the housing market in flood-prone and wildfire-prone states. Billion-dollar weather disasters — which cause about 76% of all weather-related damages — have steadily increased in number and expense in recent years and would be even worse were it not for improved weather forecasts and better building codes. The recent increase in weather-disaster losses has brought on an insurance crisis — especially in Florida , Louisiana , California , and Texas — which threatens one of the bedrocks of the U.S. economy, the housing and real estate market.

In California, the insurer of last resort, the FAIR plan, had only about $250 million in cash on hand as of March 2024.

“One major fire near Lake Arrowhead, where the Plan holds $8 billion in policies, would plunge the whole scheme into insolvency,” observed Harvard’s Susan Crawford, author of “Charleston: Race, Water, and the Coming Storm.”

It is widely acknowledged that higher weather disaster losses result primarily from an increase in exposure : more people with more stuff moving into vulnerable places, including those at risk of floods. Martin Bertogg, Swiss Re’s head of catastrophic peril, said in a 2022 AP interview that two-thirds, perhaps more, of the recent rise in weather-related disaster losses is the result of more people and things in harm’s way.

But this balance will likely shift in the coming decades. Increased exposure will continue to drive increased weather disaster losses, but the fractional contribution of climate change to disaster losses — at least for wildfire, hurricane, and flood disasters — is likely to increase rapidly, making the insurance crisis accelerate.

County-level property overvaluation in the U.S. from flood risk

A 2023 study (Fig. 2) drew attention to a massive real estate bubble in the U.S.: the vast number of properties whose purported value doesn’t account for the true costs of floods. The study estimated that across the U.S., residential properties are overvalued by a total of $121-$237 billion under current flood risks. This bubble will likely continue to grow as sea levels rise, storms dump heavier rains, and unwise risky development continues.

Likewise, U.S. properties at risk of wildfires are collectively overvalued by about $317 billion, according to David Burt , a financial guru who foresaw the 2008 subprime mortgage crisis. Insurers are already pulling out of the areas most at risk, threatening to make property ownership too expensive for millions and posing a serious threat to the economically critical real estate industry.

Climate futurist Alex Steffen has described the climate change-worsened real estate bubble this way:

As awareness of risk grows, the financial value of risky places drops. Where meeting that risk is more expensive than decision-makers think a place is worth, it simply won’t be defended. It will be unofficially abandoned. That will then create more problems. Bonds for big projects, loans, and mortgages, business investment, insurance, talented workers — all will grow more scarce. Then, value will crash, a phenomenon I call the Brittleness Bubble .

Something brittle is prone to a sudden, catastrophic failure and cannot easily be repaired once broken. The popping of the real estate Brittleness Bubble will potentially trigger panic selling and a housing market collapse like a miniature version of the Great Financial Crisis of 2008 but focused on the 20% of American homes in wildfire and flood risk zones. In his 2023 Congressional testimony , Burt estimated that a wildfire and flood-induced repricing of risk of the U.S. housing market could have a quarter to half the impact of the 2008 Great Financial Crisis.

However, the 2008 crisis was relatively short-lived, as fixes to the financial system and a massive federal bailout led to a rebound in property values after a few years. A climate change-induced housing crisis will likely be resistant to a similar fix because the underlying cause will worsen: Sea levels will continue to rise, flooding heavy rains will intensify, and wildfires will grow more severe, increasing risk.

Science writer Eugene Linden wrote in 2023, “as we saw in 2008, a housing crisis can quickly morph into a systemic financial crisis because banks own most of the value, and thus the risk, in housing and commercial real estate.”

Crawford of Harvard recently wrote : “Because insurance can help communities and households recover more quickly from disasters, and because so much of the U.S. economy is driven by spending on housing, the inaccessibility and unaffordability of insurance poses a threat to the stability of the entire economy.”

As Sen. Sheldon Whitehouse , a Democrat from Rhode Island, said earlier this year, “The thing about economic crises is that they come on slowly, until they come on fast.”

How the insurance crisis may play out: the “Wholly irrational and completely ad-hoc pirate capitalism” solution

In his blunt 2023 essay, “ Insurance Politics at the End of the World ,” journalist Hamilton Nolan offers these thoughts on the potential ways this climate change-induced insurance crisis could be addressed:

The rational capitalism solution here is: We accurately price your risk and that risk becomes unaffordable and people move away from areas that are stupid to live in and therefore climate adaptation is achieved. The rational socialism solution is: We collectively embrace the idea that we need to adapt to climate change and the federal government creates long-term programs that incentivize moving away from areas that are stupid to live in and disincentivize “build as much crap in South Florida flood zones as you can now to take advantage of the real estate bubble” and generally cushion the economic blow for all the people whose lives will have to change. The path we are on today, though — the path that our current political system makes likely — is the path of Wholly Irrational and Completely Ad-Hoc Pirate Capitalism: Increasing climate change-induced disasters cause panic among homeowners as a class; politicians rush to grab dollars to enable everyone to live the same as they are now for as long as possible; and eventually the whole thing crashes into the wall of reality in a way that causes uncontainable, national pain rather than just the specific, regional, temporary pain of the smarter solutions.

When will the Brittleness Bubble pop?

When might this “crash into the wall of reality” happen and the Brittleness Bubble pop? Politicians are working extremely hard to keep their jobs by delaying this day of reckoning, artificially limiting insurance rate rises and offering state-run insurance plans of last resort. This approach — the equivalent of giving a blood transfusion to the injured, without stopping the bleeding — does not fix the underlying problem and all but guarantees that the pain of the eventual national reckoning will be much larger. Insurance is designed to transfer risk, but risk is rising everywhere.

As the hurricane season is set to begin soon and wildfire risk gradually increasing, private insurers in some states are fleeing areas considered at high risk. It's leaving so-called "residual," or last resort plans, to pick up the tab. https://t.co/3sxv9m0FOS pic.twitter.com/YTkZ9OlJE3 — Axios (@axios) May 10, 2024

Crawford addressed the issue in a 2024 essay, “ Who ends up holding the bag when risky real estate markets collapse? ” Citing financial guru Burt, she concluded: “2025 or 2026 is when things give way and it becomes very difficult to offload houses and buildings in risky places where mortgages are suddenly hard to get, much less insurance.” When asked in an interview with Marketplace if the market is due for another correction, as homeowners in places with growing risk of flooding and wildfire have to pay more for insurance, Burt said:

This is actually happening right now and is probably going to happen over the next three to five years, like a full reckoning of these new costs for 15 or 20% of the homes in the U.S. … If all their equity is already gone [because of lowered property values], their costs are going up a ton, they can barely afford it, that’s when people walk away.

In the same Marketplace story, though, Ben Keys, a professor of real estate and finance at the University of Pennsylvania’s Wharton School, said, “The idea that we would expect there to be a huge wave of defaults or delinquencies feels relatively unlikely.”

But like Burt, climate change futurist Steffen predicts the real estate Brittleness Bubble will pop within five years (10 at the most).

I suspect we're less than 5 years away from a prolonged surge of value loss in real estate assets based on risk, insurability, economic brittleness and local capacities to ruggedize (or not). That kind of devaluation will echo through the whole economy. https://t.co/Qs0zyMS38g — Alex Steffen (@AlexSteffen) May 21, 2024

This reckoning could come sooner for Florida if another $100-billion hurricane hits. The Florida insurance and coastal property market did manage to withstand the $117-billion cost of Category 4 Hurricane Ian of 2022, but another blow like that might well cause a severe downward spiral in the Florida real estate market from which it might never fully recover. This vulnerability was underscored by Florida Gov. DeSantis during a 2023 radio interview with a Boston host, when DeSantis suggested homeowners should “ knock on wood ” and hope the state didn’t get hit by a hurricane in 2024.

But “knocking on wood” is not an effective climate adaptation strategy for Florida. Because of climate change, Mother Nature is now able to whip heavier bowling balls with more devastating impact down Hurricane Alley. It’s only a matter of time before she hurls a strike into a major Florida city, causing an intensified coastal real estate and insurance crisis. And the odds of such a strike are higher than average in 2024 because of record-warm ocean temperatures in the tropical Atlantic, combined with a developing La Niña event.

Watch out for increased coastal flooding in the mid-2030s

We may manage to avoid a coastal real estate market crash in the next 10 years if we get lucky with hurricanes and if our politicians continue to pump huge amounts of money to bail out the failing system.

But it will become increasingly difficult to keep the coastal property market propped up beginning in the mid-2030s, because of accelerating sea level rise combined with an 18.6-year wobble in the moon’s orbit. Thus, I expect that the longest we might stave off the popping of the coastal real estate Brittleness Bubble is 15 years.

As I wrote in my 2023 post, 30 great tools to determine your flood risk in the U.S. , beginning in 2033, the moon will be in a position favorable for bringing higher tides to locations where one high tide and low tide per day dominate. This will bring a rapid increase in high tide flooding to the coasts of the Gulf of Mexico, the Southeast, the West Coast, and Hawaii. This expected acceleration in the mid-2030s is obvious for St. Petersburg (Fig. 3), plotted using NASA’s Flooding Analysis Tool and Flooding Days Projection Tool . The rapid acceleration in coastal flooding simultaneously along a huge swathe of heavily developed U.S. coast in the mid-2030s will be sure to significantly stress the coastal housing market. And according to the Coastal Flood Resilience Project , the nation is flying blind on the possible impacts: There are no national assessments of the potential loss of major, critical infrastructure assets to coastal storms and rising seas.

Another immediate danger: a series of global extreme weather events affecting agriculture, causing global economic turmoil.

In my 2024 post, “ What are the odds that extreme weather will lead to a global food shock? ” I reviewed a 2023 report by insurance giant Lloyd’s, which modeled the odds of a globally disruptive extreme food shock event bringing simultaneous droughts in key global food-growing breadbaskets. The authors estimated that a “major” food shock scenario costing $3 trillion globally over a five-year period had a 2.3% chance of happening per year (Fig. 4). Over a 30-year period, those odds equate to about a 50% probability of occurrence — assuming the risks are not increasing each year, which, in fact, they are.

Chart of Lloyd's 2023 extreme weather leading to food and water shock scenario

Yet another concern for the U.S. is the risk of wholly unanticipated “black swan” extreme weather events that scientists didn’t see coming. As Harvard climate scientists Paul Epstein and James McCarthy wrote in a 2004 paper, “Assessing Climate Instability”: “We are already observing signs of instability within the climate system. There is no assurance that the rate of greenhouse gas buildup will not force the system to oscillate erratically and yield significant and punishing surprises.”

One example of such a punishing surprise was Superstorm Sandy of 2012, that unholy hybrid spawn of a Caribbean hurricane/extratropical storm that became the largest hurricane ever observed and one of the most damaging, costing $88 billion. And who anticipated that a siege of climate-change-intensified wildfires in western North America beginning in 2017, causing multiple summers of horrific air quality that would significantly degrade the quality of life in the West? Or the jet stream experiencing a sudden increase in unusually extreme configurations over the past 20 years, leading to prolonged periods of intense extreme weather over multiple portions of the globe simultaneously? As the late climate scientist Wally Broecker once said, “Climate is an angry beast, and we are poking at it with sticks.”

Just as concerning might be future “gray swan” events — extreme weather events that climate models anticipate could happen but exceed anything in the historical record. (“Gray swan” is an expression first coined by hurricane scientist Kerry Emanuel in his 2016 paper, “ Grey swan tropical cyclones .”) Several potential gray swan events I have written about include a $1 trillion California “ARkStorm” flood , the potential failure of the Old River Control Structure during an extreme flood that allows the Mississippi River to change course, or a storm like 2015’s Hurricane Patricia , with winds over 200 mph, hitting Miami, Galveston/Houston, Tampa, or New Orleans. The risk of gray swan events is steadily increasing.

I’m often asked if the absurdly extreme weather events we’ve been experiencing recently are the new normal. “No!” I reply. “Heat is energy, so the energy to fuel more intense extreme weather events will increase until we reach net-zero emissions. At that time, the climate will finally stabilize at a new normal with a highly dangerous level of extreme weather events.”

Barring a series of extraordinary volcanic eruptions or a major geoengineering effort, even under an optimistic “low” emissions climate scenario, the earliest the climate might stabilize is in the mid-2070s (Fig. 5); thus, the weather will grow more extreme, on average, for at least the next 50 years. Considering that CO2 emissions have not yet peaked and may be following the “Intermediate” pathway shown below, there is considerable danger that the weather will still be growing more extreme when today’s children are very old early next century. But even when net zero emissions are reached, sea level rise will continue to occur at a pace difficult to adapt to, and the climate crisis will continue to intensify.

A chart showing potential global carbon dioxide pathways, from very low to very high

The high probability that the weather will grow more extreme throughout the lifetime of everybody reading this essay means that we have to take seriously some very bad long-term threats. As I wrote in my 2022 post, “ The future of global catastrophic risk events from climate change ,” a global catastrophic risk event is defined as a catastrophe global in impact that kills over 10 million people or causes over $10 trillion (2022 USD) in damage. Since the beginning of the 20th century, there have been only three such events: World War I, World War II, and the COVID-19 pandemic. But climate change is a threat multiplier, increasing the risk of five types of global catastrophic risk events:

Coastal flooding from sea-level rise and land subsidence
Collapse of the Atlantic Meridional Overturning Circulation (AMOC), the powerful currents that circulate warm water in the tropical Atlantic Ocean to the Arctic and back (an August 2024 study gave a 59% chance of an AMOC collapse occurring before 2050)

The likeliest of these is a global catastrophic risk event from sea level rise, which is highly likely to occur by the end of the century. For example, a moderate global warming scenario will put $7.9-12.7 trillion dollars of global coastal assets at risk of flooding from sea level rise by 2100, according to a 2020 study, “ Projections of global-scale extreme sea levels and resulting episodic coastal flooding over the 21st century .” Although this study did not take into account assets that inevitably will be protected by new coastal defenses, neither did it consider the indirect costs of sea level rise from increased storm surge damage, mass migration away from the coast, increased saltiness of fresh water supplies, and many other factors. A 2019 report by the Global Commission on Adaptation estimated that sea level rise will lead to damages of more than $1 trillion per year globally by 2050.

Furthermore, sea level rise, combined with other stressors, might bring about megacity collapse — a frightening possibility when infrastructure destruction, salinification of freshwater resources, and a real estate collapse potentially combine to create a mass exodus of people from a major city, reducing its tax base to the point that it can no longer provide basic services. The collapse of even one megacity might have severe impacts on the global economy, creating increased chances of a cascade of global catastrophic risk events. One megacity potentially at risk of this fate is the capital of Indonesia, Jakarta, with a population of 10 million. Land subsidence of up to two inches per year and sea level rise of about an eighth of an inch per year are causing so much flooding in Jakarta that Indonesia is constructing a new capital city in Borneo.

Is the #AMOC approaching a tipping point? Here's my take after researching this topic for over 30 years. Open access, peer-reviewed, in full colour & understandable for non-experts. https://t.co/gMu6Zw5mR7 pic.twitter.com/mrgzO9NMxR — Prof. Stefan Rahmstorf 🌏 🦣 (@rahmstorf) April 11, 2024

I also expect one or more climate change-amplified global catastrophic risk events from drought will occur this century. Mexico City, with a metro area population of 22 million, has suffered record heat over the past year, is in danger of its reservoirs running dry, and is drilling ever-deeper wells to tap an overtaxed aquifer. Though the city will muddle through the crisis now that the summer rains have come this year, what is the plan for 30 years from now, when the climate is expected to be drier and much, much hotter? Although Mexico City can greatly improve its water situation by fixing a poorly maintained system that has a 40% loss rate , it is unclear how the city will be able to survive the much hotter and drier climate of 30 years from now. And at least 10 other major cities are in a similar bind.

Technology can help us adapt to a hotter climate by providing air conditioning (if you are rich enough), but technological solutions to create more water availability when the taps run dry are much more difficult to achieve. I believe water shortages will drive a partial collapse of and mass migration out of multiple major cities 20-40 years from now, significantly amplifying global political and economic turmoil. For example, a 2010 study, “ Linkages among climate change, crop yields and Mexico-US cross-border migration ,” found that a 10% reduction in crop yields in Mexico leads to an additional 2% of the population emigrating to the United States.

In his frightening 2019 book “ Food or War ,” science writer Julian Cribb documents 25 food conflicts that have led to famine, war, and the deaths of more than a million people — mostly caused by drought. Since 1960, Cribb says, 40-60% of armed conflicts have been linked to resource scarcity, and 80% of major armed conflicts occurred in vulnerable dry ecosystems. Hungry people are not peaceful people, Cribb argues.

Though climate change itself is not accelerating faster than what climate scientists and climate models predicted , devastating impacts from climate change do seem to be accelerating. That is because the new climate is crossing thresholds beyond which an infrastructure designed for the 20th century can withstand. These breaches are occurring in tandem with an increase in exposure — more people with more stuff living in harm’s way — which is the dominant cause of the sharp increase in weather-disaster losses in recent years. It’s sobering to realize that the current U.S. insurance crisis has primarily been driven by increased exposure and foolish insurance policies that promote development in risky places — not climate change — and that climate change’s relative contribution to the crisis is set to grow significantly.

Accelerating sea level rise alone is sure to cause a massive shock to the U.S. economy; according to a 2022 report from NOAA , sea level along the U.S. coastline is projected to rise, on average, 10-12 inches (0.25-0.30 meters) in the next 30 years (2020-2050), which will be as much as the rise measured over the last 100 years (1920-2020). At this level, 13.6 million homes might be at risk of flooding by 2051 , triggering a mass migration of millions of people away from the coast.

If we add to sea-level-rise-induced migration the additional migration that will result from climate change-intensified wildfires, heatwaves, and hurricanes, we are forced to acknowledge the reality that a nation-challenging Hurricane Katrina-level climate change storm has already begun in the U.S., one which has the potential to cause catastrophic damage. As I wrote in my June post, The U.S. is finally making serious efforts to adapt to climate change , there have been some encouraging efforts to prepare for the coming mass migration. But, as I argued in my follow-up post, The U.S. is nowhere near ready for climate change , we remain woefully unprepared for what is coming.

And my subsequent post, Can a colossal extreme weather event galvanize action on the climate crisis? , argues that we should not expect that any future extreme weather event or breakdown of the climate system will galvanize the type of response needed — we’ve already had at least 13 events since 1988 that should have done so, yet have not. Even if such an event did prompt strong, transformative change, it’s too late to avoid having life turned upside-down by climate change. It’s like we’ve waited until our skin started getting red before seeking shade from the sun, and we’re only now taking our first stumbling steps toward shade. Well, it’s a long hike to shade, and a blistering sunburn is unavoidable.

Given the unprecedented nature and complexity of this planetary crisis, there is huge uncertainty on how this drama may unfold; there are climate scientists who offer a more optimistic outlook than I do (for example, Hannah Ritchie , author of “Not the End of the World”), and those who are more pessimistic ( James Hansen ).

I suggest that you make the most of the current “calm before the storm” and prepare for the chaotic times ahead, which could begin at any time. I will offer my recommendations on how to do this in my next post in this series, “What should you do to prepare for the climate change storm?”

The urgency to rapidly deal with the climate crisis was succinctly summarized by the Intergovernmental Panel on Climate Change in its latest summary report: “There is a rapidly closing window of opportunity to secure a livable and sustainable future for all.”

But taking advantage of that window of opportunity is difficult because of human psychological and political realities. In climate scientist Peter Gleick’s 2023 book, “The Three Ages of Water,” he quotes Harvard’s E.O. Wilson, father of sociobiology, who perhaps said it best: “The real problem of humanity is the following: We have Paleolithic emotions, medieval institutions, and godlike technology. And it is terrifically dangerous, and it is now approaching a point of crisis overall.”

The boat of civilization has already hit multiple rocks along the rapids of climate change and is taking on water. Perilous rapids with even more dangerous rocks and waterfalls lie before us, but the course of our boat cannot be so easily altered to avoid the rocks, because of our Paleolithic emotions and medieval institutions. As a result, we may have only a few more years — or perhaps as long as 15 years — of relative normalcy in our everyday lives here in the U.S. before the approaching climate change storm ends our golden age of prosperity. But this “golden age” was made of fool’s gold, paid for with wealth plundered from future generations.

Though this essay has dwelt on some grim realities, I am optimistic that we will prevent climate change from becoming a civilization-destroying category 5-level catastrophe. But we must fight extremely hard to correct the course of our boat and not allow its inertia to carry us into the rocks that stud the rapids of climate change. This is not a task that can be accomplished in our lifetimes.

Susan Joy Hassol, the climate communication veteran who served as a senior science writer on three National Climate Assessments, put it this way in an interview with Yale Climate Connections contributor Daisy Simmons: “This is the fight of our lives, and it’s a multigenerational task. We need what’s been called ‘cathedral thinking.’ That is, the people who started working on that stone foundation , they never saw the thing finished. It took generations to get these major works done. This is that kind of problem. And we have to all do our part. The more I act, the better I feel, because I know I’m part of the solution.”

Actions we take now will yield enormous future benefits, and the faster we undertake transformative actions to adapt to the new climate reality, the less suffering will occur. The Global Commission on Adaptation says that “every $1 invested in adaptation could yield up to $10 in net economic benefits, depending on the activity.” We should work to build our cathedral of the future with the thought that each action we take now will multiply by a factor of 10 in importance in the future.

But some of the hardest work has been done: The cornerstone of this cathedral of the future has already been laid. The clean energy revolution is here and has progressed far more rapidly than I had dared hope. Passage of the 2021 Bipartisan Infrastructure Law and 2023 Inflation Reduction Act has been instrumental in getting this cornerstone laid. Solar energy is now the cheapest source of energy in world history, and the costs of wind power and battery technology have also plummeted. Two recent reports were optimistic that climate-warming carbon dioxide emissions had finally peaked in 2023, and GDP growth has decoupled from carbon dioxide emissions in recent years, giving hope that economic growth can still occur without making the planet hotter.

At its heart, the root of the climate crisis is humanity’s spiritual inharmoniousness: We overvalue the pursuit of material wealth and we worship billionaires but undervalue growing more connected to our spiritual selves and acting to preserve and appreciate the natural systems that sustain us. Making yourself more peaceful and loving through quiet spiritual pursuits and time spent in nature will help counteract the anxiety and fear sparked by the climate crisis. But in tandem with your increased peace must come a righteous anger to “throw the money changers out of the temple” and topple the might of the fossil fuel industry and its enablers.

So put your shoulder to an oar! Help us power the boat of civilization through the rapids of climate change. All of humanity shares the same boat, and you have the opportunity to make your own unique and valuable contribution to the effort.

This is a nice way to visualize the pathway to your unique climate action. https://t.co/cjlv5XXrak — Jeff Masters (@DrJeffMasters) May 15, 2024

Why climate change is still the greatest threat to human health

Polluted air and steadily rising temperatures are linked to health effects ranging from increased heart attacks and strokes to the spread of infectious diseases and psychological trauma.

People around the world are witnessing firsthand how climate change can wreak havoc on the planet. Steadily rising average temperatures fuel increasingly intense wildfires, hurricanes, and other disasters that are now impossible to ignore. And while the world has been plunged into a deadly pandemic, scientists are sounding the alarm once more that climate change is still the greatest threat to human health in recorded history .

As recently as August—when wildfires raged in the United States, Europe, and Siberia—World Health Organization Director-General Tedros Adhanom Ghebreyesus said in a statement that “the risks posed by climate change could dwarf those of any single disease.”

On September 5, more than 200 medical journals released an unprecedented joint editorial that urged world leaders to act. “The science is unequivocal,” they write. “A global increase of 1.5°C above the pre-industrial average and the continued loss of biodiversity risk catastrophic harm to health that will be impossible to reverse.”

Despite the acute dangers posed by COVID-19, the authors of the joint op-ed write that world governments “cannot wait for the pandemic to pass to rapidly reduce emissions.” Instead, they argue, everyone must treat climate change with the same urgency as they have COVID-19.

Here’s a look at the ways that climate change can affect your health—including some less obvious but still insidious effects—and why scientists say it’s not too late to avert catastrophe.

Air pollution

Climate change is caused by an increase of carbon dioxide and other greenhouse gases in Earth’s atmosphere, mostly from fossil fuel emissions. But burning fossil fuels can also have direct consequences for human health. That’s because the polluted air contains small particles that can induce stroke and heart attacks by penetrating the lungs and heart and even traveling into the bloodstream. Those particles might harm the organs directly or provoke an inflammatory response from the immune system as it tries to fight them off. Estimates suggest that air pollution causes anywhere between 3.6 million and nine million premature deaths a year.

“The numbers do vary,” says Andy Haines , professor of environmental change and public health at the London School of Hygiene and Tropical Medicine and author of the recently published book Planetary Health . “But they all agree that it’s a big public health burden.”

People over the age of 65 are most susceptible to the harmful effects of air pollution, but many others are at risk too, says Kari Nadeau , director of the Sean N. Parker Center for Allergy and Asthma Research at Stanford University. People who smoke or vape are at increased risk, as are children with asthma.

Air pollution also has consequences for those with allergies. Carbon dioxide increases the acidity of the air, which then pulls more pollen out from plants. For some people, this might just mean that they face annoyingly long bouts of seasonal allergies. But for others, it could be life-threatening.

“For people who already have respiratory disease, boy is that a problem,” Nadeau says. When pollen gets into the respiratory pathway, the body creates mucus to get rid of it, which can then fill up and suffocate the lungs.

Even healthy people can have similar outcomes if pollen levels are especially intense. In 2016, in the Australian state of Victoria, a severe thunderstorm combined with high levels of pollen to induce what The Lancet has described as “the world’s largest and most catastrophic epidemic of thunderstorm asthma.” So many residents suffered asthma attacks that emergency rooms were overwhelmed—and at least 10 people died as a result.

Climate change is also causing wildfires to get worse, and wildfire smoke is especially toxic. As one recent study showed, fires can account for 25 percent of dangerous air pollution in the U.S. Nadeau explains that the smoke contains particles of everything that the fire has consumed along its path—from rubber tires to harmful chemicals. These particles are tiny and can penetrate even deeper into a person’s lungs and organs. ( Here’s how breathing wildfire smoke affects the body .)

Extreme heat

Heat waves are deadly, but researchers at first didn’t see direct links between climate change and the harmful impacts of heat waves and other extreme weather events. Haines says the evidence base has been growing. “We have now got a number of studies which has shown that we can with high confidence attribute health outcomes to climate change,” he says.

Workers pick tomatoes in hot weather in California.

Most recently, Haines points to a study published earlier this year in Nature Climate Change that attributes more than a third of heat-related deaths to climate change. As National Geographic reported at the time , the study found that the human toll was even higher in some countries with less access to air conditioning or other factors that render people more vulnerable to heat. ( How climate change is making heat waves even deadlier .)

That’s because the human body was not designed to cope with temperatures above 98.6°F, Nadeau says. Heat can break down muscles. The body does have some ways to deal with the heat—such as sweating. “But when it’s hot outside all the time, you cannot cope with that, and your heart muscles and cells start to literally die and degrade,” she says.

If you’re exposed to extreme heat for too long and are unable to adequately release that heat, the stress can cause a cascade of problems throughout the body. The heart has to work harder to pump blood to the rest of the organs, while sweat leeches the body of necessary minerals such as sodium and potassium. The combination can result in heart attacks and strokes .

Dehydration from heat exposure can also cause serious damage to the kidneys, which rely on water to function properly. For people whose kidneys are already beginning to fail—particularly older adults—Nadeau says that extreme heat can be a death sentence. “This is happening more and more,” she says.

Studies have also drawn links between higher temperatures and preterm birth and other pregnancy complications. It’s unclear why, but Haines says that one hypothesis is that extreme heat reduces blood flow to the fetus.

Food insecurity

One of the less direct—but no less harmful—ways that climate change can affect health is by disrupting the world’s supply of food.

What is mpox—and how does it spread?

Extreme heat is the future. Here are 10 practical ways to manage it.

Climate change both reduces the amount of food that’s available and makes it less nutritious. According to an Intergovernmental Panel on Climate Change (IPCC) special report , crop yields have already begun to decline as a result of rising temperatures, changing precipitation patterns, and extreme weather events. Meanwhile, studies have shown that increased carbon dioxide in the atmosphere can leech plants of zinc, iron, and protein—nutrients that humans need to survive.

Malnutrition is linked to a variety of illnesses, including heart disease, cancer, and diabetes. It can also increase the risk of stunting, or impaired growth , in children, which can harm cognitive function.

Climate change also imperils what we eat from the sea. Rising ocean temperatures have led many fish species to migrate toward Earth’s poles in search of cooler waters. Haines says that the resulting decline of fish stocks in subtropic regions “has big implications for nutrition,” because many of those coastal communities depend on fish for a substantial amount of the protein in their diets.

This effect is likely to be particularly harmful for Indigenous communities, says Tiff-Annie Kenny, a professor in the faculty of medicine at Laval University in Quebec who studies climate change and food security in the Canadian Arctic. It’s much more difficult for these communities to find alternative sources of protein, she says, either because it’s not there or because it’s too expensive. “So what are people going to eat instead?” she asks.

Infectious diseases

As the planet gets hotter, the geographic region where ticks and mosquitoes like to live is getting wider. These animals are well-known vectors of diseases such as the Zika virus, dengue fever, and malaria. As they cross the tropics of Cancer and Capricorn, Nadeau says, mosquitoes and ticks bring more opportunities for these diseases to infect greater swaths of the world.

“It used to be that they stayed in those little sectors near the Equator, but now unfortunately because of the warming of northern Europe and Canada, you can find Zika in places you wouldn’t have expected,” Nadeau says.

In addition, climate conditions such as temperature and humidity can impact the life cycle of mosquitoes. Haines says there’s particularly good evidence showing that, in some regions, climate change has altered these conditions in ways that increase the risk of mosquitos transmitting dengue .

There are also several ways in which climate change is increasing the risk of diseases that can be transmitted through water, such as cholera, typhoid fever, and parasites. Sometimes that’s fairly direct, such as when people interact with dirty floodwaters. But Haines says that drought can have indirect impacts when people, say, can’t wash their hands or are forced to drink from dodgier sources of freshwater.

Mental health

A common result of any climate-linked disaster is the toll on mental health. The distress caused by drastic environmental change is so significant that it has been given its own name— solastalgia .

Nadeau says that the effects on mental health have been apparent in her studies of emergency room visits arising from wildfires in the western U.S. People lose their homes, their jobs, and sometimes their loved ones, and that takes an immediate toll. “What’s the fastest acute issue that develops? It’s psychological,” she says. Extreme weather events such as wildfires and hurricanes cause so much stress and anxiety that they can lead to post-traumatic stress disorder and even suicide in the long run.

Another common factor is that climate change causes disproportionate harm to the world’s most vulnerable people. On September 2, the Environmental Protection Agency (EPA) released an analysis showing that racial and ethnic minority communities are particularly at risk . According to the report, if temperatures rise by 2°C (3.6°F), Black people are 40 percent more likely to live in areas with the highest projected increases in related deaths. Another 34 percent are more likely to live in areas with a rise in childhood asthma.

Further, the effects of climate change don’t occur in isolation. At any given time, a community might face air pollution, food insecurity, disease, and extreme heat all at once. Kenny says that’s particularly devastating in communities where the prevalence of food insecurity and poverty are already high. This situation hasn’t been adequately studied, she says, because “it’s difficult to capture these shocks that climate can bring.”

Why there’s reason for hope

In recent years, scientists and environmental activists have begun to push for more research into the myriad health effects of climate change. “One of the striking things is there’s been a real dearth of funding for climate change and health,” Haines says. “For that reason, some of the evidence we have is still fragmentary.”

Still, hope is not lost. In the Paris Agreement, countries around the world have pledged to limit global warming to below 2°C (3.6°F)—and preferably to 1.5°C (2.7°F)—by cutting their emissions. “When you reduce those emissions, you benefit health as well as the planet,” Haines says.

Meanwhile, scientists and environmental activists have put forward solutions that can help people adapt to the health effects of climate change. These include early heat warnings and dedicated cooling centers, more resilient supply chains, and freeing healthcare facilities from dependence on the electric grid.

Nadeau argues that the COVID-19 pandemic also presents an opportunity for world leaders to think bigger and more strategically. For example, the pandemic has laid bare problems with efficiency and equity that have many countries restructuring their healthcare facilities. In the process, she says, they can look for new ways to reduce waste and emissions, such as getting more hospitals using renewable energy.

“This is in our hands to do,” Nadeau says. “If we don’t do anything, that would be cataclysmic.”

Ecology has always fascinated Australian artists. Think of landscape painters like Arthur Boyd (1920–99), who was inspired by nature and committed his career and legacy to protecting it.

Boyd spent the latter part of his life painting the Shoalhaven River at Bundanon, New South Wales. The use of the land along the river for agriculture was causing erosion, disturbing soil, plant and animal life. With increased tourism and intensified use of the river, Boyd feared further destruction, and so Boyd and his wife bought land along the river during the 1970s – gifting it to the Australian people in 1993.

Since scientific studies began showing the undeniable human impacts on the climate, ecology and art have been brought together in new and urgent ways.

Ecological art can communicate the results of scientific studies, create opportunities for community-based interventions, and can even function in their own right as restorations of ecological systems.

Ecology and art

If you have ever enjoyed Sydney Park you were visiting the integrated environmental artwork Water Falls by Jennifer Turpin and Michaelie Crawford.

Water Falls consists of two sets of terracotta troughs, arranged in dramatic zig-zagging lines. As part of a constructed wetland ecosystem, the artwork harvests stormwater from the surrounding streets, preventing flooding and providing habitat for native animals. It is experienced as the rhythmic sight and sound of falling water. Ecology as art.

Ecological artists deal with the politics, language, culture, economics, ethics and aesthetics of ecology in ways that scientists sometimes fall short.

In 2012 and 2021 , Tega Brain engineered an artificial wetland system which could also wash dirty clothes. Coin Operated Wetland shows how water, although often made invisible by the urban life it sustains, is always circulating and part of us and our cities.

Many First Nations artists have pointed out the entanglements of language and Country with ecological knowledge.

Quandamooka Artist Megan Cope makes sculptural installations that engage with local ecological systems. In her work Kinyingarra Guwinyanba (“a place of oysters”, 2022), she plants sea gardens with oysters to create “a living, generative land and sea artwork that demonstrates how art can physically heal country”.

Ecological art brings scientific language into the gallery and into our conversations. Using language in different ways can be a way of rethinking human relationships to land, water and atmosphere.

Topographies

There are currently two exhibitions in Sydney showcasing interdisciplinary research on climate change communicated in artistic ways.

Topographies at the Sydney College of the Arts engages with topography: the study of the forms and features of land surface. Curator Vicky Browne describes topographies here as “the process of marking out the shape of the world”.

Magnetic Topographies , an artist collective who are featured in the exhibition were in residence in Bundanon in 2023. They extend topographic research to “avian navigations”, “earthly togetherness” and “repellent terrain”.

Biljana Novakovic’s Listen for the Beginning (2024) is an enormous piece of light blue fabric is embroidered with coloured words and phrases layered over one another, an interpretation of Gooliyari, known as Cooks River, Sydney, and sometimes as Australia’s sickest urban river .

Ben Denham’s work A Topography of Air (2024) is a collection of multisensory ecological communications and interventions. Custom electronics, barometric pressure sensors, modular synthesisers and wooden boxes are combined with dried native grasses and “the atmosphere”. We feel as though we are in a laboratory – but we are not quite sure of the experiment, or what is being measured.

Alongside this work is another piece by Denham. Generalised Diagram (2024) employs the visual language of science in the form of a flow chart, black lines on a white page, pinned to the wall, showing feedback loops between oscillators, amplifiers, bodies, politics and the atmosphere.

Denham’s sculpture and flow chart work together to explain how to understand features on maps, in graphs, and in the terrain in sensory ways. “We see the visual form on a map, we feel pressure gradients on our skin,” Denham explains .

Living Water

At the University of New South Wales Library, Living Water celebrates 75 years of water research from faculties and institutions across NSW.

The River Ends at the Ocean is a collaborative project engaging with diverse knowledge about Gooliyari.

In 2021, Aunty Rhonda Dixon-Grovenor, Astrida Neimanis and Clare Britton led a group of approximately 60 walkers along the concreted banks, restored edges, and straightened channels of the estuary, following the tide out to Kyeemagh Beach.

At the entrance to the exhibition, a film of the walk by Aunty Rhonda Dixon-Grovenor layers over a flowing sketch by Britton of the Cooks River and its tributaries.

The drawing is based on the Cooks River Environment Survey and Landscape Design: Report of the Cooks River Project (1976) and helps us understand how the river catchment, and ecological knowledge about it, has changed over time.

Another collaborative creative work, Rippon Lea Water Story , (2023) explores waters, memory, plant and animal life, and infrastructure at Rippon Lea, a colonial estate in Melbourne on Boon Wurrung Country.

In the dark space of the gallery, we are asked to listen deeply to the sounds of Melbourne’s subterranean waterways, recorded with specialist microphones called hydrophones . These underwater microphones were developed by scientists to record biotic, abiotic and anthropogenic sounds in marine environments.

Here, these recordings allow us to hear the sounds of water flowing underneath the concrete surfaces of the city.

Moving forward with art and science

Visual artists synthesise and represent different types of knowledge and language.

The exhibitions are bringing new audiences to ecological science and developing understandings needed to convince people and organisations to take action on climate change.

Coming of Age in 2024: Explore Your Political Identity and Values

What can you show or tell us to help explain what it’s like to grow up in this political moment? Submit in words, images, audio or video, from Oct. 2 to Nov. 4.

A painting of teenagers, faces blurred, huddled around a bonfire on a beach. The background is dark.

By Katherine Schulten

Every fall since 2020, we have extended an open-ended invitation to teenagers to document, reflect on or express any aspect, big or small, of what it means to be growing up right now.

In 2020 , 2021 and 2022 , this “coming of age” contest focused chiefly on the Covid-19 pandemic and its myriad effects on young people. In 2023 , to celebrate our 25th anniversary as a site, we asked our audience of teachers and students to give us an inside view into high school today.

In this year of pivotal elections around the world , we are asking how young people are developing their political and civic identities. But far from being narrowly about, say, the presidential candidates in the U.S. election, the challenge asks teenagers to think bigger — about their experiences, values, beliefs, hopes and concerns, their roles as citizens, and their understanding of how the world works (or ought to work).

We are also connecting this contest to a series of informal Student Conversation Forums on the same questions. We hope that students across the globe will first talk with one another about these essential questions and then create entries for our contest in response.

As always, students may work alone or with others, and they may compose in the medium that expresses their thoughts best. For some, that’s an essay, poem or journal entry. For others, it’s a comic, collage, drawing or song — or a video, podcast or infographic. What might it be for you?

Everything you need to get started is listed below. But if you have additional questions, please post a comment here or write to us directly at [email protected]. You might also consider hanging this one-page announcement on your class bulletin board.
