Editor’s note: Climate change predictions have repeatedly demonstrated to be estimating disasters much later than they arrive. In spite of that, climate scientists still continue to make similar predictions. In this piece, the author – a psychologist – explores the technical and psychological reasons behind this.
One of the clichés of climate change reporting is climate scientists claiming to be ‘surprised’, ‘shocked’ or ‘baffled’ by extreme events happening so much faster than predicted by their models and research studies.
These consistent underestimations are often explained by their ‘cautious’ approach which sounds reasonable, until you realise this has led the International Panel on Climate Change (IPCC) — whose role is to advise humanity on the seriousness of the climate crisis — to get their advice consistently wrong.
COP27 reinforced this problem when, as ever, the IPCC based their warnings exclusively on a synthesis of climate scientist’s reports that, they knew, underdetermined both what’s already happening and the speed of catastrophic future change.
This means most people, including those in power and in the media, genuinely don’t know how desperate things already are. Even many directly engaged with the subject, in NGOs and protest groups, don’t realise concepts like limiting warming to a ‘safe’ 1.5C global average are now meaningless — because scientists won’t tell them.
People know it’s bad but not how bad. This gap in understanding remains wide enough for denialists and minimisers to legitimise inadequate action under the camouflage of empty eco-jargon and false optimism. This gap allows nations, corporations and individuals to remain distracted by short-term crises, which, however serious, pale into insignificance compared with the unprecedented threat of climate change.
Alongside those vested interests who minimise climate change assessments, underestimates by scientists have potentially devastating consequences for humanity’s efforts to react to this threat to our survival. You don’t need to be a scientist to know that misjudging the seriousness of a situation compromises any response.
This article explains why traditional climate science methods cannot keep up with rapid change. It provides an analysis of the psychological defences that prevent most climate scientists from admitting this in public when, unofficially, they all do and say they are afraid. In conclusion, we consider how scientists can overcome this irrational position, for the good of us all
How wrong are climate scientists?
The list of new climate phenomena and related extreme events that ‘surprise’ climate scientists is endless, because it literally grows by the day.
This statement of fact is not ‘doomist’ or disputed by anyone serious, including scientists themselves. Roger Harrabin, the BBC’s environment and energy correspondent, recently confessed he is ‘scared’ — because he has listened for years to scientists telling him things were far worse than they could say officially and this is evident in today’s climate extremes.
The unprecedented 40C-plus temperatures of 2022’s UK and French heatwaves that provoked Harrabin’s disclosure, were forecast in 2019 to occur sometime after 2050 by the modelling of their national meteorological organisations. Multiple UK locations then saw 40C in 2022, while elsewhere in Europe they got closer to 50C. This led Professor Hannah Cloke of the University of Reading to admit, “Even as a climate scientist… this is scary.”
More, unusually public, panicked-sounding comments from scientists followed because these unprecedented extremes in Europe, undoubtedly caused they knew by humanity’s impact on the climate, were also experienced across the entire Northern Hemisphere, not least China which suffered ‘the worst drought in human history’ and vast areas of western USA.
These, plus epic and terrible related events like extremes of drought in the Horn of Africa, floods in Pakistan (covering an area the size of the UK), Australia and Niger, heatwaves in India and Argentina, and many others — were not anticipated anything like this soon by climate science models.
Worse, this was nothing new, recent history records an accelerating number of similar phenomena including:
· The 2021 ‘heatdomes’ in British Columbia and elsewhere — predicted to occur only every 10 years after average global temperature increased by 2C i.e. again, sometime after 2050. These led Michael E. Mann, a ‘go-to’ climate scientist/commentator, to state the climate models were wrong.
· The mega Australian wildfires of 2019 — predicted to occur by 2050 by only one climate scientist who, when he said so in 2007, was ridiculed by his peers for being alarmist.
So, the answer to the question, ‘how wrong are climate scientists?’ is — disastrously. The fact is, no mainstream research paper or climate model predicted where we are now.
Why don’t the methods work?
These ‘peer-reviewed’ methods cannot keep up in a time of rapid climate change because they…
1. take years from proposal to publication — so are always out-of-date
2. must limit themselves to the consideration of fragments of the climate system, to satisfy the high statistical standards of ‘certainty’ required
3. don’t include known variables, such as methane, when measurement is problematic — these are allocated zero values which works for the maths but not for real-life
4. cannot make provision for variables they know must be significant but cannot say so ‘scientifically’ yet, including many ‘feedback loops’
5. cannot co-ordinate well with other, equally-limited studies
6. cannot consider the whole planetary system or, usually, even major system components
7. were designed for the study of nature’s usual, long-term (thousands/millions of years) pace of climate change, not the unprecedented speed of anthropogenic change.
The IPCC
The IPCC rely exclusively on data they ‘synthesise’ from scientific papers and models complying with these methods to tell humanity what is happening, though they know these are flawed for this purpose.
They will not consider better data until a scientist has referred to this using the same process.
In addition, they use a ‘consensus’ filter — this disregards ‘outlier’ results, so those few studies that sound more realistic alarms are discounted.
All this is compounded by the IPCC’s mind-bogglingly complicated 7-year review and reporting structure. Though designed to be thorough, this has no chance of keeping up.
This modus operandi was established at their inception in 1988 but, as Naomi Oreskes, the Harvard science historian says, the IPCC ‘set the bar of proof too high’ for their vital advisory role.
For clarity, this is the bar set by the IPCC for their synthesis of scientific evidence, not for their summaries issued to policymakers. These summaries are built on the foundation of this understated evidence but are further watered-down, under external pressures, by dubious factors such as the estimated impact of unproven technologies.
The Arctic Circle
This is where these methods get it most wrong.
Significant, unambiguous new observational evidence emerged in the summer of 2022, from Svalbard and the Barents Sea, to reveal an increase of 10C there in the past 30 years alone. Accounts of Alaskan and Northern Russian land masses recording even higher temperature anomalies have been routine for decades; in this context the Siberian wildfires of 2020 surpassed in area the rest of the world’s fires put together.
We now know the temperature across the entire Arctic Circle has increased by between 4C and 10C in four decades i.e. way above the current ‘global average’ of 1.2C, and the now-unachievable ‘safe’ limit of 1.5C. The drastic climatic consequences of these astonishingly fast increases include already altering the path and speed of the jet streams, 50–100 years faster than expected.
These increases were not built into climate models prior to 2022, one of the major reasons all bar one of the IPCC’s current ‘trajectories’ for future change have already been surpassed. Additional incorrect assumptions are regularly highlighted — a December 2022 study indicates the rate of melt of Greenland’s glacier fronts has been significantly underestimated in the models due to erroneous comparisons with events in Antartica.
The effect on leaders’ and the public’s (mis)understanding is significant. At the time of writing, on the back of the summer temperature extremes of 2022, 2/3 of the landmass of the USA is in the grip of a vast winter storm, while much of Europe experiences an unprecedented winter heatwave. Any climate scientist, informally, will say these events must be related to climate change caused by human activity. But they won’t say so publicly, because their methods cannot show this yet, so the media report the cause is subject to ‘scientific debate’ — creating a false impression of uncertainty and reducing warranted alarm.
We see similar misguided misreporting in relation to changes in other major climate elements including ocean temperatures, deep ocean currents, Antarctica, glacier retreat and biodiversity loss.
Another cliché of climate reporting is the surprise expressed at so many extreme events happening at ‘only’ 1.2C but given what’s actually happened in the Arctic Circle and elsewhere — as opposed to what the models predicted — it’s no surprise at all.
They do know – So why can’t climate scientists tell us?
This is where psychology comes into it. Climate scientists are extremely clever people but they are as human, and as vulnerable to sub-conscious needs and fears, as the rest of us.
They do know
It is worth reiterating that these highly-educated professionals do know everything outlined above to be true — they know EVERY new live observation and better-quality study or model shows this.
And it isn’t only Roger Harrabin, with his significant sample size, who says so.
The problem is also well-illustrated by the fiasco of the 1.5C average ‘limit’ which at COP27, using their methodology, the IPCC still declared realistic in spite of the fact that in 2022:
· the UN’s own Environment Program declared there was no credible path to limiting warming to 1.5C
· the journal Nature broadly surveyed climate scientists and ecologists on the average global temperature rise by 2100; 96% said it would be higher than 1.5C and 60% said it would be 3C or more
· an event at the University of East Anglia asked 60 climate scientists whether 1.5C was ‘still alive’? — 100% said no.
But, because most climate scientists will not say so in public, they enable COP27, virtually all media outlets and influential figures like Sir David Attenborough to keep misrepresenting reality.
All while, everyone agrees, every fraction of a degree beyond 1.5C of warming represents exponentially-worse consequences for humanity — and more than 3C could be unsurvivable.
The psychological reasons
Scientists nonetheless repress the fact all this points to an urgent need to change their behaviours to allow them to report ‘live’ – what they know is actually happening.
This repression process is automatic — it is a sub-conscious, psychological defence mechanism activated in response to the perceived threat that changing their ways of working represents.
The superficial element of this threat is to their basic needs; climate scientists in general are not motivated by material gain but they still need to eat. All of them, from the most junior to those contributing work to the IPCC, simply cannot vary from these prescribed ‘scientific’ methods in their activities — if they do, their work will not be accepted.
More significant for climate scientists, however, is the profound psychological importance to them of their professional standing, this is fundamental to their sense of themselves — we might say their egos ‘identify’ with this. The threat to this status that the possibility of abandoning these methods represents is experienced as a kind of mortal danger, a killing of themselves.
This ego-identification of scientists with their special status is not a new concept; it’s widely accepted as a kind of anodyne, hard-earned, superiority complex that’s generally beneficial in its consequences for society. Historically this was often seen in popular culture as an inferiority complex, producing the malevolent ‘mad scientist’, but in the era of advanced technology the isolated ‘nerd’ archetype has emerged from this shadow to enjoy elevated status and influence. The tendency towards social awkwardness of many in this group is also affectionately portrayed in shows like ‘The Big Bang Theory’.
But most scientists still feel psychologically different. They grew up apart because they were more intellectually capable than those around them. Even if surrounded by good-intentions, childhood inevitably featured isolation, in the absence of many who could connect with them at their level. Worse, a significant subset of this population experience bullying for their exceptional abilities.
Academia provides a psychological refuge among a social group of their peers, but they also discover here a competitive environment with rigid and complex rules of behaviour. These rules, to which these research methods are fundamental, are reinforced over years. They are the code they must abide by to confirm and retain their membership of the group.
It follows that any threat to this membership, as breaking these rules represents, is deeply psychologically painful. The defences and complexes activated, linked to early maturational experiences, are the most difficult to shift. They provoke sub-conscious, primitive fears. Rational argument, normally the goal of scientists, becomes difficult to engage.
These fears are reinforced by the absence of an alternative group to join if they leave — outcast, back in the ‘real’ world they would find no safe community.
Thus, ongoing repression and ‘business as usual’; thousands of limited studies and inaccurate models still flow from academia, and on to the IPCC — in spite of the desperate, wider consequences.
This is an example of collective cognitive dissonance, a behaviour which denies reality, often seen in human groups where individuals place high value on their membership.
Another crucial barrier to these scientists changing their behaviours is the near absence of any external pressure to do so — indeed the opposite is the case. Efforts to dilute climate warnings continue but even those who acknowledge the problem, enmeshed in their own obligations and related defences, don’t want to hear things are worse than scientists are already saying.
The psychology of the IPCC
The continued insistence of the IPCC on basing their advice on evidence produced by methods they know under-estimate the problem, is an extension of this collective cognitive dissonance.
Their behaviour makes no sense in the context of humanity’s failure to respond to catastrophic threat. IPCC lead scientists are not pathologically-inclined to cause harm — but they too feel unable to abandon the constraints of methods within which they are psychologically secure.
It is also likely the IPCC reinforces their emphasis on these flawed in-group methods, as a primitive defence against those non-scientific vested interests who challenge and ‘bully’ them, including in the production of their summaries for policymakers.
There is, nonetheless, one psychological factor that could shift these ‘ego-identified’ complexes and that is peer pressure, especially if this comes from senior leaders across the climate science community.
The truth is ‘unscientific’
Roger Harrabin reports scientists saying they can’t tell the truth because to do so would be ‘unscientific’. This apparent insanity, given the consequences, can be understood psychologically.
But scientists are not the only ones who need urgent analysis in this incredible context. Prioritising survival in their roles at the expense of rational behaviour is accepted, even expected, among corporate leaders and politicians, both as individuals and the collective.
It’s notable all these people come from a similar demographic— mostly white, male, middle-aged, privileged — or, if not, they are obliged to conform with the culture and social norms established by this group. It may be easier for scientists though, given the importance to them of objectivity, to break through their defences and change their behaviours.
The same but different – Divergence among climate scientists
The climate science community, like the science itself, is many-faceted and includes specialists in atmospheric sciences, fluid dynamics, meteorology, geo-science and others, as well as climatologists. More than one hundred thousand work in research, corporations, environment/habitat management, public administration, NGOs etc. Most have no direct connection to the IPCC or the media.
Only their leaders have these connections and it is no surprise, in this extreme situation, that this instinctively-conservative community is fragmenting. They currently fall into 5 main groups.
1. More of the same
In classic defence-mechanism style many scientists double-down on their existing flawed methods in response to their fears. Disappearing down the rabbit-hole of another 5-year study or designing another complex model is psychologically comfortable. Most research papers still end with the recommendation ‘more study is required…’, which rationalises this defensive behaviour but diminishes the impact of conclusions and plays into the hands of minimisers.
Ineffectual attempts have been made to change things up like, ‘attribution studies’. These calculate (using a questionable comparison to an imaginary world where human influence had not occurred) the probability of anthropogenic causation as opposed to ‘weather’ variations. Their findings are published faster than standard studies but still cause delays of many months and even then are not conclusive. Thus the summer 2022 droughts were reported in January 2023 to have been ‘calculated’ by the UK Met Office as ‘160 times more likely’ to have been caused by climate change, when any scientist would have said, informally, when they were happening, there was no chance it was anything else. Others produce ludicrous individual event estimates like ‘1000 times more…’
Anything to avoid a declaration of certainty at the time of the event, because this is not allowed by scientific method. Such convoluted compromises only make sense within the climate science community where adherence to the rules is sacrosanct — even though they know these will still cause delay in communication and misunderstanding elsewhere.
2. More of the same — but magically better
Senior climate scientist and Oxford Professor Tim Palmer told Roger Harrabin: “It’s impossible to say how much of an emergency we are in because we don’t have the tools to answer the question.’’
Former Met Office chief scientist Professor Dame Julia Slingo told BBC News in 2021: “We should be alarmed because the IPCC (climate computer) models are just not good enough.’’ She went on, “(We need) an international centre… like that at Cern… with expensive new mega-computers — to deliver the quantum leap to climate models that capture the fundamental physics that drive extremes”. Such computers — everyone knows — would take years to develop, time humanity does not have, and could anyway never be ‘mega’ enough to keep up.
It is difficult to imagine clearer cases of bad workmen blaming their tools, not least as they design the tools themselves — but it’s not that a Professor Dame and an Oxford Professor can’t see the wood for the trees, it is that they are the trees.
Most climate scientists still live deep in this area of a forest of their own creation. Their irrational obsession with improving ‘scientific’ methods as a response to this problem, clearly links to their subconsciously-driven resistance to saying anything in public without reference to these; they are looking for justification (within the rules of their community) to speak out, as they know they should. Off the record, Tim and Julia and the rest will say it is 100% certain humanity caused this unprecedented climate mayhem and — using their powerful brains instead of their limited models — can give accurate ideas of what’s coming next.
3. Ongoing denial
A small group of hardliners still refuse to look beyond conclusions derived within the limited parameters of individual studies and models. They disregard the fact these, and the big picture the IPCC obtains by considering them together, cannot tell us what’s actually going on. For them if something can’t be ‘proved’ yet by their methods — it’s not happening.
Thus many refused to accept jet streams had (inevitably) shifted because of the relative speed of Arctic warming — because their models could not yet demonstrate this. Their peer-reviewed work was published in credible journals, even when other scientists like Jennifer Francis pointed out obvious flaws, such as their inability to include the impact of the warming of land masses across the Arctic Circle. This purist group were quietened by the observations and events of 2022 but they remain influential.
Crucially, the IPCC itself belongs here — as they continue to reference only data from studies and models which they know cannot reflect reality.
4. Underestimation to ‘avoid panic’
Some scientists attempt to rationalise underestimation by claiming this avoids the paralysis the resultant panic would provoke. This, psychologically-speaking, is nonsense; history tells us the mass ‘freeze response’ they allude to will not be provoked by credible experts telling the truth. Not telling people, however, does risk confusion, paralysis and no meaningful action — which is what has played out.
These scientists collude with the ‘stubborn optimists’ in public life, people like the UN’s Cristiana Figueres who advocate maintaining a belief in things getting better, even when they look bleak — which sounds okay but, has led to magical thinking such as faith in non-viable techno-solutions and the untenable insistence on ‘keeping 1.5C alive’.
This group includes public-facing scientists like Katherine Hayhoe and Michael E Mann, popular because they say what people want to hear. Mann now acknowledges there has been no meaningful action. He still insists ‘progress’ made on ‘policy’ is ‘hopeful’, however, which is like praising the driver of a runaway train for jamming down the accelerator, before going back to talk with passengers about slowing down. So, he hasn’t found his way out of this group yet.
5. Going public
Some scientists are breaking ranks to tell it much more like it is. They include some whose reputations are established, like Sir David King, or are retired/emeritus professors like Peter Wadhams, or they are the more confident and the boldest, people like James Hansen, Makifo Sato, Jennifer Francis, Ye Tao, Bill McGuire, Peter Carter, Kevin Anderson, Tim Lenton, Jason Box, David Spratt, James Dyke and Peter Kalmus. They are not rooted so deeply within the forest and have in common the psychological trait that the existential fear in them provoked by this situation, has become stronger than any psychological threat.
Some are organising in groups such as Scientist Rebellion, The Climate Crisis Advisory Group, Scientists Warning, and Scholars Warning. Some of the youngest are breathing fire — Capstick et al in 2022 in the journal Nature Climate Change, argue that all climate scientists must get involved in civil disobedience to provoke action. Others focus on practical suggestions — but do so in silos which receive minimal attention, such as the Centre for Climate Repair.
Other academics are also realistically engaged including Jem Bendell, professor of Sustainable Leadership and Rupert Read, Associate Professor of Philosophy.
Though in touch with reality themselves, and connecting with probably several million others now across the globe, none of these or others like them have had a meaningful impact on the behaviour of governments, corporations and most individuals, nor on humanity’s omnicidal trajectory.
Scientists, collectively, telling the unvarnished truth about the desperate seriousness of the situation, right now, is something that could have this impact.
How can climate scientists allow themselves to tell the truth?
1. Admit the problem
Climate scientists must admit they are still the only ones who know the extent of the climate iceberg below the surface.
They must accept, in the face of this unprecedented threat, their primary professional responsibility now is to provide up-to-date information to humanity — about what’s really happening to our climate and to our essential habitat. This is the single most important task any group of scientists has ever faced.
They have to admit that rigid adherence to their academic methods, in this astonishingly rapid context, leads directly to their failure to communicate the truth.
They have to acknowledge the confusion this failure has provoked facilitates inadequate action, empty pledges, fantasy techno-solutions, and false-optimism.
Scientists must concede humanity urgently needs them to find new ways to communicate what they already know, not only what their methods, or some future super-computer, will allow.
2. Unite and co-ordinate
Pointing to accelerating climate-extreme events happening ahead of their predictions — and the failure of humanity to respond linked, in part, to these underestimations — senior scientists must build a new ‘permanent-emergency’ coalition of IPCC and climate science leaders from all disciplines.
This strong new coalition must overcome their psychological resistances to agree an urgent new direction for the climate science community, finding a way through the politics to co-ordinate this.
The attraction of civil disobedience as a potential catalyst is understandable — and the climate science community should support members who get involved.
Accurate information communicated effectively, however, has the best chance of provoking meaningful action, in the form of impulses to radically change originating from within governments and corporations, including fossil fuel companies.
The new coalition must collectively acknowledge it is climate scientists themselves who need to lead in these communications and ensure they are effective. To do this they will need to engage with psychological and comms experts to break through the defences of leaders in all spheres of human activity, as well as the wider population.
3. Plan and Act
This coalition must initiate a plan of action that could look something like this.
1. Announce the permanent-emergency
Getting ahead of the likely unprecedented new extremes of the 2023/2024 El Niño, issue statement to all media platforms (simultaneously from all national agencies, IPCC, NASA, NOAA, NSDIC, UK Met Office and equivalents, all university Climate Change departments, Institutes etc), declaring:
· A new state of climate ‘permanent-emergency’ is here. Comparisons with the past are now irrelevant — our climate has irrevocably changed, at a speed unprecedented in this planet’s history and will change ever faster, with devastating impacts much faster than expected.
· Traditional climate science methods could not predict this and cannot keep up — ‘live’ observation, interpretation and communication of this new climate reality will now be the priority of scientists.
· Humanity has to react without further delay. 1.5C is gone. Paris 2015 goals, COP pledges, carbon budgets etc are obsolete — radical new policies are needed.
· These must promote urgent, meaningful action in all areas of human activity, based on new ‘live’ information.
2. Initiate new Permanent-Emergency Climate Science Code of Practice
· All institutions and individual climate scientists required to adopt
· Requires all activity (teaching, funding, research, modelling, other activity) prioritises live observations, analysis and reporting.
· Requires senior climate scientists behave congruently in their professional actions — eg 40% of time allocated to external facing comms/education and personally ensuring colleagues adopt this code.
3. Co-ordinate global climate scientific resources as a permanent-emergency response
· Create new 24/7 network of climate hubs, based in existing institutions, with the primary purpose of live analysis of weather/climate events, probable future events and related parameters — all individuals and institutions to prioritise their work for these hubs.
· Ensure hubs are co-ordinated to cover and connect planet-wide climate activity.
· Task hubs with improving quality of live observations including in remote locations. Advance computer capabilities — without delaying communication of live information.
· Set up central ‘planet hub’ at the IPCC — the coalition base — operates 24/7 to co-ordinate/ integrate/synthesise work of individual hubs.
· Using psychological approaches, engage with resistance from within the climate science community and related disciplines.
· Promote emergency-first mobilisation of all academic disciplines.
· All in co-ordination with government, corporate, NGO, health, education, social care and arts etc sectors — includes delivery of rolling information programs.
4. Set up 24/7 primary communication centre at IPCC ‘Planet Hub’
· Provides rolling analysis in planet-wide report, continuously synthesises and translates technical work of individual hubs into accessible language — replaces 7-yearly reporting cycle.
· Pro-actively engages with psychological resistance in leaders and the wider public to ensure effective communications.
· Supervises parallel/reciprocal communication functions in all climate hubs.
· Engages and trains media-friendly scientists.
· Targets rolling comms/education programs at all media platforms — eradicates misconceptions, replaces with accurate narrative.
Conclusion and questions for scientists
This article is aimed primarily at climate scientists, related professions and the media, written by a psychotherapist/friend. Someone with enough post-graduate education to understand the scientific papers and the climate models, and their shortcomings, but without the professional authority to do more than hold a psychological mirror up to this group.
The aim is to encourage scientists to overcome their resistances to communicating what they know. Because if they don’t — then we all face the prospect of the end of civilised society, including academia, also much faster than expected.
It is beyond the scope of this article to argue how bad the situation is or what appropriate responses should look like. The truth is no-one knows if we have 5 years or 50 before societal collapse sets in — but there is no doubt, whatever the timeframe, the situation is desperate and there is still no sign this is properly understood.
The climate science community could have a crucial influence in closing this gap in understanding — no-one else in this arena gets close to their hard-earned authority.
From this point the author only has questions because, as we say in psychotherapy, ‘insight is half the battle’. Changing behaviours is the difficult other half. It is for scientists themselves to answer the following:
· Can climate scientists overcome the subconsciously-driven defences that prevent most of them from telling the truth in public?
· Can they re-organise themselves to take responsibility for the effective communication of the true severity of this unprecedented ‘permanent-emergency’?
· Can they lower their self-imposed ‘bar of proof’ to a rational level that allows them to competently perform, at last, this vital role — so minimisers can be negated and meaningful actions initiated?
· Can they engage with parallel psychological resistances in leaders, the media and the public to receiving this information?
· Can they play the unique part, only their expertise allows them to play, in reducing harm to billions of human beings and other species?
“All ethics so far evolved rest upon a single premise: that the individual is a member of a community of interdependent parts. The land ethic simply enlarges the boundaries of the community to include soils, waters, plants and animals, or collectively the land.” – Aldo Leopold, The Land Ethic, A Sand County Almanac.
Land change is a scientific term you’re not likely to hear in mainstream climate conversation, which is a shame, because what it refers to, the climatic effects of human damage to living landscapes, is a big part of the climate crisis. I talk in greater detail about land change and how it got left out of the climate narrative in an earlier Resilience piece, called Putting the Land Back in Climate. Here, I want to consider the effects of this omission, not only in the practical terms of climate policy, but in terms less definitive. What does it mean to our treatment of the land that it’s gotten to be left out of our picture of climate? Or another way of putting it: how does not knowing that our local landscapes hydrate, cool and stabilize our climates, affect our relationship with those landscapes or lack thereof?
But first I want to be clear that nothing here questions or counters the danger of carbon emissions, the greenhouse effect, or subsequent global warming. Land change should be seen as being in addition to these things, or more to the point, intimately entwined with them. The climate, when fully comprehended, emerges as a constellation of actors and effects, physical and biological, with an unimaginable complexity of feedbacks and signals. To reduce it all to quantities of carbon, and speak only of that, is to miss the thing itself.
So let’s quickly review what land change is and how it got left out the climate picture.
One way to think of land change is as original climate change. We began changing climates as soon as we started draining marshes and plowing soil, as observed in the time-worn adage: desert follows the plow, and seen now in deserts like those of the Middle East, which were once lush with marshlands and cypress-draped hills. The reason has to do with water cycles, which are largely invisible to us. We don’t see the roots underground, interlinking with extravagant webbings of soil fungi, soaking up spongelike massive quantities of water, around 600 liters per day for the average tree. Nor do we see the water evaporating from microscopic pores under the surfaces of leaves and needles, which like all evaporation, is profoundly cooling. And we don’t see the columns of vapor rising from trees and fields, feeding the clouds overhead to rain somewhere else and continue the cycle. Lastly, we don’t see the soil absorbing and holding that moisture, banking the landscape against drought and flood. Life not only sequesters carbon, it sequesters water as well. The two, it turns out, go hand in hand.
Scientists refer to this with the term evapotranspiration and know it to be fundamental to the hydration, cooling and moderation of local and regional climates. It follows then, that when we damage, or “change” land it dries out, heats up, and becomes prone to hydrological extremes like drought, floods and heatwaves. Sound familiar?
When coal and oil was discovered, a new cause of climate change entered the picture: emissions of greenhouse gasses. And early climate science treated it that way, as an additional cause, not the cause. Mediterranean-climate expert Millan Millan remembers that time, referring to it as a “two-legged” climate understanding—one leg for land change and hydrological effects and a second leg for carbon emissions and the greenhouse effect. So how then did we arrive at an official narrative which describes only carbon emissions as the cause of climate change? What happened to the land leg?
A clue can be found in the titles of the IPCC’s periodical Assessment Reports, such as the most recent assessment Global Climate Change 2021: The Physical Science Basis. What is meant by those last four words? The easiest answer is to think of the physical science basis is as the mathematic, or quantitative basis, the basis necessary for the computer modelling of climate. When CO2 emissions emerged as a climate threat, science immediately turned to computer modelling to ascertain and predict the effects. Carbon emissions, well dispersed in the atmosphere, proved highly amenable to such modeling, while the biological/hydrological processes of land change were the opposite. Though we can feel the effects of land-change, and are surrounded by it in the form of wastelands and vanished species, it is almost impossible to render in quantitative terms. The processes are too detailed, complex, varied and changing.
A good many scientists are currently working to resolve the matter, quantifying land change effects and bringing them into global computer models, and we can expect the next round of IPCC assessments to include some of this work. But that’s still five to six years off, and by then trillions will have been spent on industrial infrastructure causing how much land change?
This must be the first and most tragic effect of leaving land change and water cycles out of the analysis. Nature disappears, reduced to quantities of carbon, buried under tech jargon, sacrificed all over again for a new era of human device and progress. To the plow, the ax and cattle drive, we now add the solar farm, transmission corridor and a new generation of mines.
Environmentalism has suffered mightily from this formulation, and now confronts a kind of ecological Sophie’s Choice: either sacrifice the land or sacrifice the climate. It can be that stark. Consider the US state of Virginia, who’s recently passed climate legislation is resulting in thousands of acres of forest being cut for solar farms and transmission corridors, much of it to support data centers for tech corporations like Google and Microsoft. Meanwhile, those citizens who elect to protect their forests rather than sacrifice them for energy generation are labeled NIMBYs.
But there’s more. With this big industrial push comes a parallel push for what is being called “permit reform.” The Inflation Reduction Act, recently passed in the US, contains 1.2 billion dollars to staff up permitting agencies in an attempt to rush this infrastructure. And I noticed, when Senator Joe Manchin tried to attach a “permit reform” bill to the IRA, the official environmental opposition was carefully directed at only the permitting reform around fossil fuels. Presumably, they are for it when it comes to industrial infrastructure deemed “green” or “clean.” Thus, another dichotomy: big green working to take away permitting power from little green, the locals defending their own land bases. Ask yourself how long you think such contradictions can last.
There’s a personal dimension here as well. I know for myself, once I began learning about the biological, water-based aspects of climate, my view of climate and the natural world transformed. Muir’s oft-quoted observation, “when we try to pick out anything by itself, we find it hitched to everything else in the universe” suddenly came alive. I discovered, over and over, that when I grabbed the thread called “climate” it was hitched to everything on Earth, part of something very much alive and capable of recovery. And with that my doom, not my worry and concern and grief, but that powerless sense of doom vanished. I stood on different ground, having come to know its power.
Now I see my surroundings, my climate-shed if you will, not as climatically helpless against rising CO2 emissions, but the very basis for climate healing and recovery. This is what happens when you bring the living land back into the climate equation, it comes alive. The land turns ally, and a new clarity emerges, with a very different set of priorities.
First, protect all remaining wild and semi-wild places. They are the last living links to the once cool, wet Holocene climate, which we can still save. Understand that where land is at its healthiest, so it’s climate function.
Second, restore the lands we’ve already damaged. Here is where hope literally grows. For buried within the sad fact that half of Earth’s land has been converted to human use, is the stunning comprehension of just how much land is available and waiting for restoration, bringing new carbon sequestration and water cycling to the climate system at game-changing scale.
Third, stop “changing” land. Housing developments, logging, road building, solar farming, all continue with no public awareness of the climate damage being done. Integrate land change into the environmental review process.
Fourth, slow down, cool down—the only thing that ever has reduced emissions. The land is telling it needs rest and recovery, not to be subjected to a new industrial revolution.
Do we really need decades of climate modelling to figure these things out? Might there be other ways of approaching this crisis?
We are not alone in this. For the land, though degraded, still retains its potential for regeneration. Given a little protection, ecosystems recover. Even the poorest soils contain ancient seeds of bygone life, awaiting only water. And in the field, the land’s enthusiasm for reemergence continually exceeds the expectations of those working to restore it. It turns out that regeneration, and the passion for regeneration, is in the very grain and fiber of all that surrounds us.
Those seeds are in us too. That’s the invitation. But only the land, and the processes of life, can bring the water.
Editor’s Note: Global warming is a serious threat to our planet, and, along with mass extinction, wildlife population collapse, habitat destruction, desertification, aquifer drawdown, oceanic dead zones, pollution, and other ecological issues, is one of the primary symptoms of overshoot and industrial civilization.
This paper, published last month in the Proceedings of the National Academy of Sciences, explores the prospect of catastrophic global warming, noting that “There is ample evidence that climate change could become catastrophic… at even modest levels of warming.”
With outcomes such as runaway global warming, oceanic hypoxia, and mass mortality becoming more certain with each passing day, the justifications for Deep Green Resistance are only becoming stronger.

Prudent risk management requires consideration of bad-to-worst-case scenarios. Yet, for climate change, such potential futures are poorly understood. Could anthropogenic climate change result in worldwide societal collapse or even eventual human extinction? At present, this is a dangerously underexplored topic. Yet there are ample reasons to suspect that climate change could result in a global catastrophe. Analyzing the mechanisms for these extreme consequences could help galvanize action, improve resilience, and inform policy, including emergency responses. We outline current knowledge about the likelihood of extreme climate change, discuss why understanding bad-to-worst cases is vital, articulate reasons for concern about catastrophic outcomes, define key terms, and put forward a research agenda. The proposed agenda covers four main questions: 1) What is the potential for climate change to drive mass extinction events? 2) What are the mechanisms that could result in human mass mortality and morbidity? 3) What are human societies’ vulnerabilities to climate-triggered risk cascades, such as from conflict, political instability, and systemic financial risk? 4) How can these multiple strands of evidence—together with other global dangers—be usefully synthesized into an “integrated catastrophe assessment”? It is time for the scientific community to grapple with the challenge of better understanding catastrophic climate change.
How bad could climate change get? As early as 1988, the landmark Toronto Conference declaration described the ultimate consequences of climate change as potentially “second only to a global nuclear war.” Despite such proclamations decades ago, climate catastrophe is relatively under-studied and poorly understood.
The potential for catastrophic impacts depends on the magnitude and rate of climate change, the damage inflicted on Earth and human systems, and the vulnerability and response of those affected systems. The extremes of these areas, such as high temperature rise and cascading impacts, are underexamined. As noted by the Intergovernmental Panel on Climate Change (IPCC), there have been few quantitative estimates of global aggregate impacts from warming of 3 °C or above (1). Text mining of IPCC reports similarly found that coverage of temperature rises of 3 °C or higher is underrepresented relative to their likelihood (2). Text-mining analysis also suggests that over time the coverage of IPCC reports has shifted towards temperature rise of 2 °C and below https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022EF002876. Research has focused on the impacts of 1.5 °C and 2 °C, and studies of how climate impacts could cascade or trigger larger crises are sparse.
A thorough risk assessment would need to consider how risks spread, interact, amplify, and are aggravated by human responses (3), but even simpler “compound hazard” analyses of interacting climate hazards and drivers are underused. Yet this is how risk unfolds in the real world. For example, a cyclone destroys electrical infrastructure, leaving a population vulnerable to an ensuing deadly heat wave (4). Recently, we have seen compound hazards emerge between climate change and the COVID-19 pandemic (5). As the IPCC notes, climate risks are becoming more complex and difficult to manage, and are cascading across regions and sectors (6).
Why the focus on lower-end warming and simple risk analyses? One reason is the benchmark of the international targets: the Paris Agreement goal of limiting warming to well below 2 °C, with an aspiration of 1.5 °C. Another reason is the culture of climate science to “err on the side of least drama” (7), to not to be alarmists, which can be compounded by the consensus processes of the IPCC (8). Complex risk assessments, while more realistic, are also more difficult to do.
This caution is understandable, yet it is mismatched to the risks and potential damages posed by climate change. We know that temperature rise has “fat tails”: low-probability, high-impact extreme outcomes (9). Climate damages are likely to be nonlinear and result in an even larger tail (10). Too much is at stake to refrain from examining high-impact low-likelihood scenarios. The COVID-19 pandemic has underlined the need to consider and prepare for infrequent, high-impact global risks, and the systemic dangers they can spark. Prudent risk management demands that we thoroughly assess worst-case scenarios.
Our proposed “Climate Endgame” research agenda aims to direct exploration of the worst risks associated with anthropogenic climate change. To introduce it, we summarize existing evidence on the likelihood of extreme climate change, outline why exploring bad-to-worst cases is vital, suggest reasons for catastrophic concern, define key terms, and then explain the four key aspects of the research agenda.
Worst-Case Climate Change
Despite 30 y of efforts and some progress under the United Nations Framework Convention on Climate Change (UNFCCC) anthropogenic greenhouse gas (GHG) emissions continue to increase. Even without considering worst-case climate responses, the current trajectory puts the world on track for a temperature rise between 2.1 °C and 3.9 °C by 2100 (11). If all 2030 nationally determined contributions are fully implemented, warming of 2.4 °C (1.9 °C to 3.0 °C) is expected by 2100. Meeting all long-term pledges and targets could reduce this to 2.1 °C (1.7 °C to 2.6 °C) (12). Even these optimistic assumptions lead to dangerous Earth system trajectories. Temperatures of more than 2 °C above preindustrial values have not been sustained on Earth’s surface since before the Pleistocene Epoch (or more than 2.6 million years ago) (13).
Even if anthropogenic GHG emissions start to decline soon, this does not rule out high future GHG concentrations or extreme climate change, particularly beyond 2100. There are feedbacks in the carbon cycle and potential tipping points that could generate high GHG concentrations (14) that are often missing from models. Examples include Arctic permafrost thawing that releases methane and CO2 (15), carbon loss due to intense droughts and fires in the Amazon (16), and the apparent slowing of dampening feedbacks such as natural carbon sink capacity (17, 18). These are likely to not be proportional to warming, as is sometimes assumed. Instead, abrupt and/or irreversible changes may be triggered at a temperature threshold. Such changes are evident in Earth’s geological record, and their impacts cascaded across the coupled climate–ecological–social system (19). Particularly worrying is a “tipping cascade” in which multiple tipping elements interact in such a way that tipping one threshold increases the likelihood of tipping another (20). Temperature rise is crucially dependent on the overall dynamics of the Earth system, not just the anthropogenic emissions trajectory.
The potential for tipping points and higher concentrations despite lower anthropogenic emissions is evident in existing models. Variability among the latest Coupled Model Intercomparison Project Phase 6 (CMIP6) climate models results in overlap in different scenarios. For example, the top (75th) quartile outcome of the “middle-of-the-road” scenario (Shared Socioeconomic Pathway 3-7.0, or SSP3-7.0) is substantially hotter than the bottom (25th) quartile of the highest emissions (SSP5-8.5) scenario. Regional temperature differences between models can exceed 5 °C to 6 °C, particularly in polar areas where various tipping points can occur (https://www.pnas.org/doi/10.1073/pnas.2108146119#supplementary-materials).
There are even more uncertain feedbacks, which, in a very worst case, might amplify to an irreversible transition into a “Hothouse Earth” state (21) (although there may be negative feedbacks that help buffer the Earth system). In particular, poorly understood cloud feedbacks might trigger sudden and irreversible global warming (22). Such effects remain underexplored and largely speculative “unknown unknowns” that are still being discovered. For instance, recent simulations suggest that stratocumulus cloud decks might abruptly be lost at CO2 concentrations that could be approached by the end of the century, causing an additional ∼8 °C global warming (23). Large uncertainties about dangerous surprises are reasons to prioritize rather than neglect them.
Recent findings on equilibrium climate sensitivity (ECS) (14, 24) underline that the magnitude of climate change is uncertain even if we knew future GHG concentrations. According to the IPCC, our best estimate for ECS is a 3 °C temperature rise per doubling of CO2, with a “likely” range of (66 to 100% likelihood) of 2.5 °C to 4 °C. While an ECS below 1.5 °C was essentially ruled out, there remains an 18% probability that ECS could be greater than 4.5 °C (14). The distribution of ECS is “heavy tailed,” with a higher probability of very high values of ECS than of very low values.
There is significant uncertainty over future anthropogenic GHG emissions as well. Representative Concentration Pathway 8.5 (RCP8.5, now SSP5-8.5), the highest emissions pathway used in IPCC scenarios, most closely matches cumulative emissions to date (25). This may not be the case going forward, because of falling prices of renewable energy and policy responses (26). Yet, there remain reasons for caution. For instance, there is significant uncertainty over key variables such as energy demand and economic growth. Plausibly higher economic growth rates could make RCP8.5 35% more likely (27).
Why Explore Climate Catastrophe?
Why do we need to know about the plausible worst cases? First, risk management and robust decision-making under uncertainty requires knowledge of extremes. For example, the minimax criterion ranks policies by their worst outcomes (28). Such an approach is particularly appropriate for areas characterized by high uncertainties and tail risks. Emissions trajectories, future concentrations, future warming, and future impacts are all characterized by uncertainty. That is, we can’t objectively prescribe probabilities to different outcomes (29). Climate damages lie within the realm of “deep uncertainty”: We don’t know the probabilities attached to different outcomes, the exact chain of cause and effect that will lead to outcomes, or even the range, timing, or desirability of outcomes (, 30). Uncertainty, deep or not, should motivate precaution and vigilance, not complacency.
Catastrophic impacts, even if unlikely, have major implications for economic analysis, modeling, and society’s responses (31, 32). For example, extreme warming and the consequent damages can significantly increase the projected social cost of carbon (31). Understanding the vulnerability and responses of human societies can inform policy making and decision-making to prevent systemic crises. Indicators of key variables can provide early warning signals (33).
Knowing the worst cases can compel action, as the idea of “nuclear winter” in 1983 galvanized public concern and nuclear disarmament efforts. Exploring severe risks and higher-temperature scenarios could cement a recommitment to the 1.5 °C to 2 °C guardrail as the “least unattractive” option (34).
Understanding catastrophic climate scenarios can also inform policy interventions, including last-resort emergency measures like solar radiation management (SRM), the injection of aerosols into the stratosphere to reflect sunlight (35).
Whether to resort to such measures depends on the risk profiles of both climate change and SRM scenarios. One recent analysis of the potential catastrophic risk of stratospheric aerosol injection (SAI) found that the direct and systemic impacts are under-studied (36). The largest danger appears to come from “termination shock”: abrupt and rapid warming if the SAI system is disrupted. Hence, SAI shifts the risk distribution: The median outcome may be better than the climate change it is offsetting, but the tail risk could be worse than warming (36).
There are other interventions that a better understanding of catastrophic climate change could facilitate. For example, at the international level, there is the potential for a “tail risk treaty”: an agreement or protocol that activates stronger commitments and mechanisms when early-warning indicators of potential abrupt change are triggered.
The Potential for Climate Catastrophe
There are four key reasons to be concerned over the potential of a global climate catastrophe. First, there are warnings from history. Climate change (either regional or global) has played a role in the collapse or transformation of numerous previous societies (37) and in each of the five mass extinction events in Phanerozoic Earth history (38). The current carbon pulse is occurring at an unprecedented geological speed and, by the end of the century, may surpass thresholds that triggered previous mass extinctions (39, 40). The worst-case scenarios in the IPCC report project temperatures by the 22nd century that last prevailed in the Early Eocene, reversing 50 million years of cooler climates in the space of two centuries (41).
This is particularly alarming, as human societies are locally adapted to a specific climatic niche. The rise of large-scale, urbanized agrarian societies [editors note: civilization] began with the shift to the stable climate of the Holocene ∼12,000 y ago (42). Since then, human population density peaked within a narrow climatic envelope with a mean annual average temperature of ∼13 °C. Even today, the most economically productive centers of human activity are concentrated in those areas (43). The cumulative impacts of warming may overwhelm societal adaptive capacity.
Second, climate change could directly trigger other catastrophic risks, such as international conflict, or exacerbate infectious disease spread, and spillover risk. These could be potent extreme threat multipliers.
Third, climate change could exacerbate vulnerabilities and cause multiple, indirect stresses (such as economic damage, loss of land, and water and food insecurity) that coalesce into system-wide synchronous failures. This is the path of systemic risk. Global crises tend to occur through such reinforcing “synchronous failures” that spread across countries and systems, as with the 2007–2008 global financial crisis (44). It is plausible that a sudden shift in climate could trigger systems failures that unravel societies across the globe.
The potential of systemic climate risk is marked: The most vulnerable states and communities will continue to be the hardest hit in a warming world, exacerbating inequities. Fig. 1 shows how projected population density intersects with extreme >29 °C mean annual temperature (MAT) (such temperatures are currently restricted to only 0.8% of Earth’s land surface area). Using the medium-high scenario of emissions and population growth (SSP3-7.0 emissions, and SSP3 population growth), by 2070, around 2 billion people are expected to live in these extremely hot areas. Currently, only 30 million people live in hot places, primarily in the Sahara Desert and Gulf Coast (43).
Fig. 1.
Overlap between future population distribution and extreme heat. CMIP6 model data [from nine GCM models available from the WorldClim database (45)] were used to calculate MAT under SSP3-7.0 during around 2070 (2060–2080) alongside Shared SSP3 demographic projections to ∼2070 (46). The shaded areas depict regions where MAT exceeds 29 °C, while the colored topography details the spread of population density.
Extreme temperatures combined with high humidity can negatively affect outdoor worker productivity and yields of major cereal crops. These deadly heat conditions could significantly affect populated areas in South and southwest Asia (47).
Fig. 2 takes a political lens on extreme heat, overlapping SSP3-7.0 or SSP5-8.5 projections of >29 °C MAT circa 2070, with the Fragile States Index (a measurement of the instability of states). There is a striking overlap between currently vulnerable states and future areas of extreme warming. If current political fragility does not improve significantly in the coming decades, then a belt of instability with potentially serious ramifications could occur.
Fig. 2.
Fragile heat: the overlap between state fragility, extreme heat, and nuclear and biological catastrophic hazards. GCM model data [from the WorldClim database (45)] was used to calculate mean annual warming rates under SSP3-7.0 and SSP5-8.5. This results in a temperature rise of 2.8 °C in ∼2070 (48) for SSP3-7.0, and 3.2 °C for SSP5-8.5. The shaded areas depict regions where MAT exceeds 29 °C. These projections are overlapped with the 2021 Fragile State Index (FSI) (49). This is a necessarily rough proxy because FSI only estimates current fragility levels. While such measurements of fragility and stability are contested and have limitations, the FSI provides one of the more robust indices. This Figure also identifies the capitals of states with nuclear weapons, and the location of maximum containment Biosafety Level 4 (BS4) laboratories which handle the most dangerous pathogens in the world. These are provided as one rough proxy for nuclear and biological catastrophc hazards.
Finally, climate change could irrevocably undermine humanity’s ability to recover from another cataclysm, such as nuclear war. That is, it could create significant latent risks (Table 1): Impacts that may be manageable during times of stability become dire when responding to and recovering from catastrophe. These different causes for catastrophic concern are interrelated and must be examined together.

Defining the Key Terms
Although bad-to-worst case scenarios remain underexplored in the scientific literature, statements labeling climate change as catastrophic are not uncommon. UN Secretary-General António Guterres called climate change an “existential threat.” Academic studies have warned that warming above 5 °C is likely to be “beyond catastrophic” (50), and above 6 °C constitutes “an indisputable global catastrophe” (9).Current discussions over climate catastrophe are undermined by unclear terminology. The term “catastrophic climate change” has not been conclusively defined. An existential risk is usually defined as a risk that cause an enduring and significant loss of long-term human potential (51, 52). This existing definition is deeply ambiguous and requires societal discussion and specification of long-term human values (52). While a democratic exploration of values is welcome, it is not required to understand pathways to human catastrophe or extinction (52). For now, the existing definition is not a solid foundation for a scientific inquiry.We offer clarified working definitions of such terms in Table 1. This is an initial step toward creating a lexicon for global calamity. Some of the terms, such as what constitutes a “plausible” risk or a “significant contributor,” are necessarily ambiguous. Others, such as thresholding at 10% or 25% of global population, are partly arbitrary (10% is intended as a marker for a precedented loss, and 25% is intended as an unprecedented decrease; see SI Appendix for further discussion). Further research is needed to sharpen these definitions. The thresholds for global catastrophic and decimation risks are intended as general heuristics and not concrete numerical boundaries. Other factors such as morbidity, and cultural and economic loss, need to be considered.
We define risk as the probability that exposure to climate change impacts and responses will result in adverse consequences for human or ecological systems. For the Climate Endgame agenda, we are particularly interested in catastrophic consequences. Any risk is composed of four determinants: hazard, exposure, vulnerability, and response (3).
We have set global warming of 3 °C or more by the end of the century as a marker for extreme climate change. This threshold is chosen for four reasons: Such a temperature rise well exceeds internationally agreed targets, all the IPCC “reasons for concern” in climate impacts are either “high” or “very high” risk between 2 °C and 3 °C, there are substantially heightened risks of self-amplifying changes that would make it impossible to limit warming to 3 °C, and these levels relate to far greater uncertainty in impacts.
Key Research Thus Far
The closest attempts to directly study or comprehensively address how climate change could lead to human extinction or global catastrophe have come through popular science books such as The Uninhabitable Earth (53) and Our Final Warning (10). The latter, a review of climate impacts at different degrees, concludes that a global temperature rise of 6 °C “imperils even the survival of humans as a species” (10).
We know that health risks worsen with rising temperatures (54). For example, there is already an increasing probability of multiple “breadbasket failures” (causing a food price shock) with higher temperatures (55). For the top four maize-producing regions (accounting for 87% of maize production), the likelihood of production losses greater than 10% jumps from 7% annually under a 2 °C temperature rise to 86% under 4 °C (56). The IPCC notes, in its Sixth Assessment Report, that 50 to 75% of the global population could be exposed to life-threatening climatic conditions by the end of the century due to extreme heat and humidity (6). SI Appendix provides further details on several key studies of extreme climate change.
The IPCC reports synthesize peer-reviewed literature regarding climate change, impacts and vulnerabilities, and mitigation. Despite identifying 15 tipping elements in biosphere, oceans, and cryosphere in the Working Group 1 contribution to the Sixth Assessment Report, many with irreversible thresholds, there were very few publications on catastrophic scenarios that could be assessed. The most notable coverage is the Working Group II “reasons for concern” syntheses that have been reported since 2001. These syntheses were designed to inform determination of what is “dangerous anthropogenic interference” with the climate system, that the UNFCCC aims to prevent. The five concerns are unique and threatened ecosystems, frequency and severity of extreme weather events, global distribution and balance of impacts, total economic and ecological impact, and irreversible, large-scale, abrupt transitions. Each IPCC assessment found greater risks occurring at lower increases in global mean temperatures. In the Sixth Assessment Report, all five concerns were listed as very high for temperatures of 1.2 °C to 4.5 °C. In contrast, only two were rated as very high at this temperature interval in the previous Assessment Report (6). All five concerns are now at “high” or “very high” for 2 °C to 3 °C of warming (57).
A Sample Research Agenda: Extreme Earth System States, Mass Mortality, Societal Fragility, and Integrated Climate Catastrophe Assessments
We suggest a research agenda for catastrophic climate change that focuses on four key strands:
Understanding extreme climate change dynamics and impacts in the long term
Exploring climate-triggered pathways to mass morbidity and mortality
Investigating social fragility: vulnerabilities, risk cascades, and risk responses
Synthesizing the research findings into “integrated catastrophe assessments”
Our proposed agenda learns from and builds on integrated assessment models that are being adapted to better assess large-scale harms. A range of tipping points have been assessed (58–60), with effects varying from a 10% chance of doubling the social cost of carbon (61) up to an eightfold increase in the optimal carbon price (60). This echoes earlier findings that welfare estimates depend on fat tail risks (31). Model assumptions such as discount rates, exogenous growth rates, risk preferences, and damage functions also strongly influence outcomes.
There are large, important aspects missing from these models that are highlighted in the research agenda: longer-term impacts under extreme climate change, pathways toward mass morbidity and mortality, and the risk cascades and systemic risks that extreme climate impacts could trigger. Progress in these areas would allow for more realistic models and damage functions and help provide direct estimates of casualties (62), a necessary moral noneconomic measure of climate risk. We urge the research community to develop integrated conceptual and semiquantitative models of climate catastrophes.
Finally, we invite other scholars to revise and improve upon this proposed agenda.
Extreme Earth System States.
We need to understand potential long-term states of the Earth system under extreme climate change. This means mapping different “Hothouse Earth” scenarios (21) or other extreme scenarios, such as alternative circulation regimes or large, irreversible changes in ice cover and sea level. This research will require consideration of long-term climate dynamics and their impacts on other planetary-level processes. Research suggests that previous mass extinction events occurred due to threshold effects in the carbon cycle that we could cross this century (40, 63). Key impacts in previous mass extinctions, such as ocean hypoxia and anoxia, could also escalate in the longer term (40, 64).
Studying potential tipping points and irreversible “committed” changes of ecological and climate systems is essential. For instance, modeling of the Antarctic ice sheet suggests there are several tipping points that exhibit hysteresis (65). Irreversible loss of the West Antarctic ice sheet was found to be triggered at ∼2 °C global warming, and the current ice sheet configuration cannot be regained even if temperatures return to present-day levels. At a 6 °C to 9 °C rise in global temperature, slow, irreversible loss of the East Antarctic ice sheet and over 40 m of sea level rise equivalent could be triggered (65). Similar studies of areas such as the Greenland ice sheet, permafrost, and terrestrial vegetation would be helpful. Identifying all the potential Earth system tipping elements is crucial. This should include a consideration of wider planetary boundaries, such as biodiversity, that will influence tipping points (66), feedbacks beyond the climate system, and how tipping elements could cascade together (67).
Mass Morbidity and Mortality.
There are many potential contributors to climate-induced morbidity and mortality, but the “four horsemen” of the climate change end game are likely to be famine and undernutrition, extreme weather events, conflict, and vector-borne diseases. These will be worsened by additional risks and impacts such as mortality from air pollution and sea level rise.
These pathways require further study. Empirical estimates of even direct fatalities from heat stress thus far in the United States are systematically underestimated (68). A review of the health and climate change literature from 1985 to 2013 (with a proxy review up to 2017) found that, of 2,143 papers, only 189 (9%) included a dedicated discussion of more-extreme health impacts or systemic risk (relating to migration, famine, or conflict) (69). Models also rarely include adaptive responses. Thus, the overall mortality estimates are uncertain.
How can potential mass morbidity and mortality be better accounted for? 1) Track compound hazards through bottom-up modeling of systems and vulnerabilities (70) and rigorously stress test preparedness (71). 2) Apply models to higher-temperature scenarios and longer timelines. 3) Integrate risk cascades and systemic risks (see the following section) into health risk assessments, such as by incorporating morbidity and mortality resulting from a climate-triggered food price shock.
Societal Fragility: Vulnerabilities, Risk Cascades, and Risk Responses.
More-complex risk assessments are generally more realistic. The determinants of risk are not just hazards, vulnerabilities, and exposures, but also responses (3, 72). A complete risk assessment needs to consider climate impacts, differential exposure, systemic vulnerabilities, responses of societies and actors, and the knock-on effects across borders and sectors (73), potentially resulting in systemic crises. In the worst case(s), a domino effect or spiral could continuously worsen the initial risk.
Societal risk cascades could involve conflict, disease, political change, and economic crises. Climate change has a complicated relationship with conflict, including, possibly, as a risk factor (74) especially in areas with preexisting ethnic conflict (75). Climate change could affect the spread and transmission of infectious diseases, as well as the expansion and severity of different zoonotic infections (76), creating conditions for novel outbreaks and infections (6,77). Epidemics can, in turn, trigger cascading impacts, as in the case of COVID-19. Exposure to ecological stress and natural disasters are key determinants for the cultural “tightness” (strictness of rules, adherence to tradition, and severity of punishment) of societies (78). The literature on the median economic damages of climate change is profuse, but there is far less on financial tail risks, such as the possibility of global financial crises.
Past studies could be drawn upon to investigate societal risk. Relatively small, regional climate changes are linked to the transformation and even collapse of previous societies (79, 80). This could be due to declining resilience and the passing of tipping points in these societies. There is some evidence for critical slowing down in societies prior to their collapse (81, 82). However, care is needed in drawing lessons from premodern case studies. Prehistory and history should be studied to determine not just how past societies were affected by specific climate hazards but how those effects differ as societies change with respect to, for example, population density, wealth inequality, and governance regime. Such framing will allow past and current societies to be brought under a single system of analysis (37).
The characteristics and vulnerabilities of a modern globalized world where food and transport distribution systems can buffer against traumas will need to feature in work on societal sensitivity. Such large, interconnected systems bring their own sources of fragility, particularly if networks are relatively homogeneous, with a few dominant nodes highly connected to everyone else (83). Other important modern-day vulnerabilities include the rapid spread of misinformation and disinformation. These epistemic risks are serious concerns for public health crises (84) and have already hindered climate action. A high-level and simplified depiction of how risk cascades could unfold is provided in Fig. 3.

See SI Appendix for further information.
Integrated Catastrophic Assessments.
Climate change will unfold in a world of changing ecosystems, geopolitics, and technology. Could we even see “warm wars”—technologically enhanced great power conflicts over dwindling carbon budgets, climate impacts, or SRM experiments? Such developments and scenarios need to be considered to build a full picture of climate dangers. Climate change could reinforce other interacting threats, including rising inequality, demographic stresses, misinformation, new destructive weapons, and the overshoot of other planetary boundaries (85). There are also natural shocks, such as solar flares and high-impact volcanic eruptions, that present possible deadly synchronicities (86). Exploring these is vital, and a range of “standardized catastrophic scenarios” would facilitate assessment.
Expert elicitation, systems mapping, and participatory scenarios provide promising ways of understanding such cascades (73). There are also existing research agendas for some of these areas that could be funded (87).
Integration can be approached in several ways. Metareviews and syntheses of research results can provide useful data for mapping the interactions between risks. This could be done through causal mapping, expert elicitation, and agent-based or systems dynamics modeling approaches. One recent study mapped the evidence base for relationships between climate change, food insecurity, and contributors to societal collapse (mortality, conflict, and emigration) based on 41 studies (88).
A particularly promising avenue is to repurpose existing complex models to study cascading risks. The resulting network could be “stress tested” with standardized catastrophic scenarios. This could help estimate which areas may incur critical shortages or disruptions, or drastic responses (such as food export bans). Complex models have been developed to help understand past large-scale systemic disasters, such as the 2007–2008 global financial crisis (89). Some of these could be repurposed for exploring the potential nature of a future global climate crisis.
Systems failure is unlikely to be globally simultaneous; it is more likely to begin regionally and then cascade up. Although the goal is to investigate catastrophic climate risk globally, incorporating knowledge of regional losses is indispensable.
The potentially catastrophic risks of climate change are difficult to quantify, even within models. Any of the above-mentioned modeling approaches should provide a greater understanding of the pathways of systemic risk, and rough probabilistic guides. Yet the results could provide the foundation for argumentation-based tools to assess the potential for catastrophic outcomes under different levels of temperature rise (90). These should be fed into open deliberative democratic methods that provide a fair, inclusive, and effective approach to decision-making (91). Such approaches could draw on decision-making tools under uncertainty, such as the minimax principle or ranking decisions by the weighted sum of their best and worst outcomes, as suggested in the Dasgupta review of biodiversity (92).
An IPCC Special Report on Catastrophic Climate Change
The IPCC has yet to give focused attention to catastrophic climate change. Fourteen special reports have been published. None covered extreme or catastrophic climate change. A special report on “tipping points” was proposed for the seventh IPCC assessment cycle, and we suggest this could be broadened to consider all key aspects of catastrophic climate change. This appears warranted, following the IPCC’s decision framework (93). Such a report could investigate how Earth system feedbacks could alter temperature trajectories, and whether these are irreversible.
A special report on catastrophic climate change could help trigger further research, just as the “Global warming of 1.5 °C” special report (94) did. That report also galvanized a groundswell of public concern about the severity of impacts at lower temperature ranges. The impact of a report on catastrophic climate change could be even more marked. It could help bring into focus how much is at stake in a worst-case scenario. Further research funding of catastrophic and worst-case climate change is critical.
Effective communication of research results will be key. While there is concern that fear-invoking messages may be unhelpful and induce paralysis (95), the evidence on hopeful vs. fearful messaging is mixed, even across metaanalyses (96, 97). The role of emotions is complex, and it is strategic to adjust messages for specific audiences (98). One recent review of the climate debate highlighted the importance of avoiding political bundling, selecting trusted messengers, and choosing effective frames (99). These kinds of considerations will be crucial in ensuring a useful and accurate civic discussion.
Conclusions
There is ample evidence that climate change could become catastrophic. We could enter such “endgames” at even modest levels of warming. Understanding extreme risks is important for robust decision-making, from preparation to consideration of emergency responses. This requires exploring not just higher temperature scenarios but also the potential for climate change impacts to contribute to systemic risk and other cascades. We suggest that it is time to seriously scrutinize the best way to expand our research horizons to cover this field. The proposed “Climate Endgame” research agenda provides one way to navigate this under-studied area. Facing a future of accelerating climate change while blind to worst-case scenarios is naive risk management at best and fatally foolish at worst.

22 years ago on this very continent was brought to the negotiating table the crisis of climate change. Many evasive proposals, claims to turn the crisis into an opportunity for business, denials, omissions and grand tragedies embody the climate crisis in the territories. A balance of 22 years of indifference and cynicism.
Governments and transnational interests continue to invest in the destruction of forests, rivers, oceans, jungles, mashlands, mountains and deserts; living spaces that end up being sacrificed in the name of “development” and “progress”.
In these 22 years, we are far from believing that the solution will come from governments; that the market will contribute to environmental conservation, or that the commodification of nature will protect the climate.
Our view is the way of indigenous communities that have known to preserved ecosystems, in farming communities who struggle to protect their lands, in women who work caringly in the rivers, in the children that keep alive their capacity of fascination with nature, and in the inhabitants of large cities who know that they have been robbed from nature since birth. Our guardians.
Us, the very ones who we are, have come here to convince you (and convince ourselves of the certainty that the world we want already exists), as there are colors of the earth, the suns that shine us, and the ways of our guardians that defend the territories around the globe.
This is why we call to find ourselves on the road to the COP20, to join our histories, our views, and our ways that demand climate justice under these guiding principles:
1. Maintain the fossil fuels underground is not only a priority to halting environmental devastation, but to end one of the evils that has so hurt and changed the pace of the climate in very few decades.
2. Ban the financialization of forests and the commodification of the functions of nature, as they are not a solutions to reduce emissions of carbon gases into the atmosphere; strategies which represent false solutions that have increased the destruction of ecosystems, the breakdown of communitarian social fabric and organization.
3. Water, as a common good can no longer be conceived as a commodity. Dams and hydroelectric dams are part of the mining and energy industries. The production of hydroelectric power is what keeps widening the gap of environmental devastation.
The aggressiveness with which the occupation of territories intends to expand itself does not depend on the political color of governments, but rather is linked to the perpetuation of the capitalist system under the same logic of accumulation at the expense of nature and communities.
Therefore, it becomes more urgent to find one another, Us.
They are the ones who will find the solutions- It’s us, the unadaptaded, the unadaptable climate change- It is us that can and must contain the war against nature.
If you’ve been a sentient being for the last few months, you’ve probably been watching some of the most curious weather events happening throughout the world.
Of particular concern for many scientists has been the Arctic sea ices melt, which dropped to its lowest level on record last summer. In the first few months of this year, large cracks were witnessed in the sea ice, indicating a great possibility that it has entered a death spiral and will disappear completely in the summer months within the next two years.
The rapid melt (and eventual disappearance) of the ice is having drastic affects on the jet stream in the northern hemisphere, creating powerful storms and extreme weather events, largely outside the comprehension of many scientists.
Jeff Masters, meteorology director at the private service Weather Underground states: “I’ve been doing meteorology for 30 years and the jet stream the last three yeas has done stuff I’ve never seen. […] The fact that the jet stream is unusual could be an indicator of something. I’m not saying we know what it is.”
For example, in May there were wildfires caused by excessive heat in California while at the same time there was more than a foot of snow in Minnesota. Spring in Colorado started with early wildfires and was subsequently followed by massive flooding. Massive floods have been devastating much of the northern hemisphere this spring, including Canada, the United States, Europe, India, and Russia.
Last week, Alaska saw its hottest days on record where the town of McGrath, Alaska hit 94 F degrees while just a few weeks earlier the local temperature was 15 F degrees. There have also been extreme heat waves throughout the southwest United States, some temperatures above 130 F degrees, also resulting in wildfires that spread to more than 6,000 acres in two days and killed 19 firefighters in Arizona.
This is catastrophic – most scientists have recognized any significant rise above 1 C will usher in irreversible changes that will threaten nearly all biological life on this planet.
Carbon dioxide has an approximate thirty-year time lag between its release into the atmosphere and its corresponding affect on average global temperature. Even if we stop all emissions today – keeping it at 400 ppm – we still have nearly thirty years of warming and climatic changes to undergo.
And right now, nothing that we are currently observing matches up with any of the models that we have – a stark acknowledgment that this historical moment we find ourselves in exists largely beyond our ability to comprehend it let alone predict its movement.
We are in uncharted territory – we are facing challenges never before experienced in the history of the human species. This presents a grave problem: if the best science we have today cannot accurately offer any model predictions for the path that we are currently on, how can we effectively plan for the future?
The honest truth: we can’t. We cannot effectively plan for a future that is beyond all known human experience.
The best that we can do now is stop exacerbating the problem – stop contributing to the rapidly accelerating decline and destruction of the Earth’s biosphere and ecosystems.
Quite literally: we have to completely dismantle the industrial economy, we have to do it soon, and really, we should have done it yesterday.
But even still, grinding industrial civilization to a complete halt today is only guaranteed to mitigate the pace at which we’re running – it is not yet clear that it will ultimately alter our direction. We have, at minimum, thirty more years of incomprehensible climate disruptions and changes to undergo no matter what happens today or tomorrow. Our only chance to still have a thriving and living planet following the coming decades is by making a complete, radical and rapid shift from the industrial economy.
The logic of industrial civilization and capitalism is immediacy – grow as quickly as possible, generate maximum profits in the shortest time, and deal with consequences and crises later (if at all). Long-term planning and strategizing is antithetical to, and bears no consequence on, the drive for capital accumulation, expansion, and domination.
This process, within the last 30-40 years alone, has resulted in such an expansive project of urbanization around the world that capitalism has triumphed over (read: conquered, murdered, and erased) all other ways of existing on this planet, human and non-human. We now live in a truly global industrial civilization – a monoculture of unprecedented scope; a totality of being and of tyranny.
To oppose this project of endless growth and centralization of control, we need to enter into the logic of a truly oppositional culture – a fundamental and radical break from of our entire material reality. This entails a complete negation of our current standard of living and entire way of being in the world. Anything short of this negation will only exacerbate the problem.
Acknowledging this does not mean that the task at hand is easy or that a majority of people will accept it as truth. In fact, even amidst collapse, most people will not resist the status quo and are likely to fight to the death to protect it.
If your experience is that your water comes from the tap and that your food comes from the grocery store then you are going to defend to the death the system that brings those to you because your life depends on that; if your experience is that your water comes from a river and that your food comes from a land base then you will defend those to the death because your life depends on them. So part of the problem is that we have become so dependent upon this system that is killing and exploiting us, it has become almost impossible for us to imagine living outside of it and it’s very difficult physically for us to live outside of it.
But this also does not mean that the task at hand is any less true. It does mean, however, that if we wish to build our struggle for a truly just and sustainable future we must first do away with our delusions, re-focus our strategies to the most effective, and be radically uncompromising in our vision.
On June 25th, Barack Obama – a president whom, despite his rhetoric of care, spent all of the last five years of his presidency completely ignoring climate change – finally addressed the nation in a speech that was supposed to signal a “serious plan forward.”
Many “environmental” groups along with the mainstream media heralded the speech as being progressive and a great commitment to the crisis at hand. In reality, much of the speech was full of nothing more than the doublespeak typical of his presidential legacy.
In a move that many considered to be a “big victory,” the president merely stated that he will ask the State Department not to approve the final construction of the Keystone XL pipeline unless it can first determine that it “will not lead to a net increase in greenhouse gas emissions.”
This is certainly a sly trick designed to pacify a building resistance, an attempt to re-frame the debate and make it appear as if our best interests are dutifully being considered. However, to even pretend that it is at all possible that this pipeline would not lead to a net increase in greenhouse gas emissions is delusional.
While the fight against the KXL has been a fight against a pipeline, it is predominantly being waged as a fight against tar sands oil production entirely. It is incredibly easy to argue that one specific pipeline will not result in significant GHG emissions if we isolate it from the very process that demands its existence in the first place.
It is the extraction process itself that is the net greenhouse gas emitter destroying the planet – not merely the nodes at which its product is transported and consumed. Although this infrastructure should be equally opposed and dismantled, stopping one pipeline being built will only mean that others will replace it or other means will be developed to export its goods.
We should settle for nothing less than a complete end to all extraction processes. It is not even close to a victory until that happens.
Despite his attempt to appease environmentalists with this speech, there were some activist groups that were rightfully confused and enraged with his hypocritical stance. In a speech meant to signal commitment to slow climate change, President Obama continued to praise and support the fossil fuel industry and hydraulic fracturing for natural gas.
Chris Williams, author of Ecology and Socialism, examines the rhetoric and reality of this latest speech, providing a great reminder of whose interests this president actually serves – those of the ruling class. He also outlines some new ideas for Obama’s consideration:
If you’re serious about stopping global warming, you need to veto KXL.
If you’re serious about moving away from dirty energy, then there needs to be a strict timeline established for the complete phasing-out of all coal and nuclear plants by 2030 and their replacement, not with natural gas or nuclear, but with wind and solar power.
If you’re really serious about carbon pollution, you can’t with any honesty discuss solutions without making massive cuts in military spending. The Department of Defense is responsible for 80 percent of the U.S. government’s energy consumption, and the U.S. military is by far the biggest polluter on the planet. Radical reductions in spending on the Pentagon are essential for human survival.
You made no mention of the need for enormous investment in and expansion of public transit. If you’re serious about addressing climate change and making our cities more livable and the air more breathable, you will take the money you just saved by cutting military expenditures and apply it to the construction of new rail, light rail, tram and bus service, between and within cities, obviating the need for cars.
These ideas are some of the more prevalent solutions that are often tossed around in environmental and social justice circles. While the intention may be sincere, simply advocating for a shift from “dirty energy” (coal, oil, nuclear) to “clean energy” (solar, wind, tidal, geothermal, etc.) does a great disservice for generating informed decision-making at such a critical historical moment.
While these energieshavemanyflaws, one of the greatest problems with their proponents is that they do not fundamentally put into question our standard of living or way of being in the world.
An often-cited study by these proponents is the work of Mark Z. Jacobson who, mere weeks after Hurricane Sandy devastated the Northeast U.S., presented the economic argument for investing in renewable energies. His plan calls for a complete shift off fossil fuels and towards a rapid investment in wind and solar power for the entire state of New York by the year 2030.
Not only was this study completed on the premise that our culture does not dramatically change its standard of living, the study fails to even acknowledge the resources required to build these new energy infrastructures.
These energy sources are not free from fossil fuels and are dependent on rare earth metals and minerals; this sort of rapid technological and social shift will require massive extractive processes – a price we simply cannot afford if we wish to stop the destruction of this planet.
If we wish to create a “sustainable” future that is also just, a question that should be immediately asked is: Where are these resources coming from? From whose land will we steal from in order to build this renewable-energy utopia? Despite the fact that New York State ranks in or near the top third of U.S. mineral production, none of the crucial metals and minerals currently used for the development of solar panels and wind turbines can be found here – we will have to steal these resources from some other land base.
Even more problematic, Jacobson’s study does not entirely take into consideration (to the extent that it is possible) the severe climatic disruptions we are unavoidably set to experience in the coming decades. The disappearance of the Arctic sea ice in the next few years will result in rising sea levels that could displace more than 400 million people globally. Is it worth the investment for an entirely new energy infrastructure that may ultimately be irrelevant by the time it can be actualized?
To continue to advocate for these “solutions,” is to continue living in the delusion that we can have our current standard of living and have a planet too. As Robert Jensen articulates in his article, “Get Apocalyptic: Why Radical is the New Normal“:
…Toughest to dislodge may be the central illusion of the industrial world’s extractive economy: that we can maintain indefinitely a large-scale human presence on the earth at something like current First-World levels of consumption. The task for those with critical sensibilities is not just to resist oppressive social norms and illegitimate authority, but to speak a simple truth that almost no one wants to acknowledge: The high-energy/high-technology life of affluent societies is a dead end. We can’t predict with precision how resource competition and ecological degradation will play out in the coming decades, but it is ecocidal to treat the planet as nothing more than a mine from which we extract and a landfill into which we dump.
We cannot know for sure what time the party will end, but the party’s over.
Our primary goal and vision for the world is a living planet. Nothing else matters. The biggest challenge to that goal is the industrial economy and it’s a moving target. If we have any chance at stopping it we cannot have a strategy that is focused solely on the injustices of today. Our actions and strategies should be based on where we’re heading – and where we’re heading is nothing short of near-term extinction.
This is not hyperbole or metaphor. 200 species went extinct today and another 200 species will go extinct tomorrow. 400,000 people die every year from climate-related deaths. A war has been declared against the living the world and we ought to start articulating which side we’re on, and we ought to seriously start fighting back.
I’m reminded of a recent quote from MEND (Movement for the Emancipation of the Niger Delta), a militant group successful at halting more than 28% of Nigeria’s oil output between 2006 and 2009, which articulates the situation succinctly:
From today, every tanker vehicle we find distributing petroleum products including propane gas has become a legitimate target in our war against injustice, corruption, despotism and oppression.
This is the kind of vigor we need to be generating in our own movement. Never before have the lines between those who seek to destroy this planet and those who seek a radically different future, been so clearly drawn and defined. Yet, there is a degree of hesitancy within the majority of activist circles in the West that is painstakingly paralyzing our movements from reaching its goals.
If we stand in solidarity with all the human and non-human lives that have been lost, or are routinely brutalized to this way of life, we must fundamentally reject our own standards of living and ideals about how to enter into relationship with each other and with the land. Knowing that we have now entered a historical moment of incomprehensible climatic disruptions and changes for the foreseeable future, we’d be better to do away with our delusions sooner rather than later.
