The world should prepare for the possibility of a "climate endgame" due to the effects of global warming, scientists have warned.
They say temperature changes could become “catastrophic” for humanity if they are worse than many predict or cause cascades of events yet to be considered.
The potential for climate change to lead to worldwide societal collapse or even human extinction is a “dangerously underexplored topic”, the international team of researchers say.
Dr Luke Kemp, from the University of Cambridge’s Centre for the Study of Existential Risk, said: “There are plenty of reasons to believe climate change could become catastrophic, even at modest levels of warming.
“Climate change has played a role in every mass extinction event.
“It has helped fell empires and shaped history.
“Even the modern world seems adapted to a particular climate niche.
“Paths to disaster are not limited to the direct impacts of high temperatures, such as extreme weather events.
“Knock-on effects such as financial crises, conflict and new disease outbreaks could trigger other calamities, and impede recovery from potential disasters such as nuclear war.”
They propose a research agenda for facing up to worst-case scenarios. These include outcomes from a loss of 10 per cent of the global population to eventual human extinction.
More research is needed about “plausible worst cases”, the group of scientists led by the University of Cambridge have argued in a paper published in the journal Proceedings of the National Academy of Sciences.
They write that there are “ample reasons to suspect that climate change could result in a global catastrophe”.
They say that analysing potential extreme consequences of climate change could “help galvanise action, improve resilience and inform policy, including emergency responses”.
The authors say that climate breakdown would likely exacerbate other “interacting threats”: from rising inequality and misinformation to democratic breakdowns and even new forms of destructive AI weaponry.
One possible future highlighted in the paper involves “warm wars” in which technologically enhanced superpowers fight over both dwindling carbon space and giant experiments to deflect sunlight and reduce global temperatures.
More focus should go on identifying all potential tipping points within “Hothouse Earth”, say researchers: from methane released by melting permafrost to the loss of forests that act as “carbon sinks”, and even potential for vanishing cloud cover.
The researchers have called on the Intergovernmental Panel on Climate Change to dedicate a future report to catastrophic climate change.
Dr Kemp and his colleagues argue that the consequences of 3°C warming and beyond, and related extreme risks, have been underexamined.
The team behind the paper proposed a research agenda that includes what they call the “four horsemen” of the climate endgame: famine and malnutrition, extreme weather, conflict and vector-borne disease.
Co-author Prof Johan Rockstrom, director of the Potsdam Institute for Climate Impact Research, said: “The more we learn about how our planet functions, the greater the reason for concern.
“We increasingly understand that our planet is a more sophisticated and fragile organism.
“We must do the maths of disaster in order to avoid it.”
Modelling done by the team shows areas of extreme heat (an annual average temperature above 29°C), could cover two billion people by 2070. These areas are not only some of the most densely populated, but also some of the most politically fragile.
“Average annual temperatures of 29°C currently affect around 30 million people in the Sahara and Gulf Coast,” said co-author Chi Xu of Nanjing University.
“By 2070, these temperatures and the social and political consequences will directly affect two nuclear powers, and seven maximum containment laboratories housing the most dangerous pathogens. There is serious potential for disastrous knock-on effects."
Last year’s IPCC report suggested that if atmospheric CO2 doubles from pre-industrial levels — something the planet is halfway towards — then there is an 18 per cent chance of temperatures rising beyond 4.5°C.
However, Dr Kemp co-authored a “text mining” study of IPCC reports, published this year, which found that IPCC assessments have shifted away from high-end warming to focus increasingly on lower temperature rises.
This builds on previous work he contributed to, showing that extreme temperature scenarios are “underexplored relative to their likelihood”.
“We know least about the scenarios that matter most,” he said.

How it works
Each player begins with one of the great empires of history, from Julius Caesar's Rome to Ramses of Egypt, spread over Europe and the Middle East.
Round by round, the player expands their empire. The more land they have, the more money they can take from their coffers for each go.
As unruled land and soldiers are acquired, players must feed them. When a player comes up against land held by another army, they can choose to battle for supremacy.
A dice-based battle system is used and players can get the edge on their enemy with by deploying a renowned hero on the battlefield.
Players that lose battles and land will find their coffers dwindle and troops go hungry. The end goal? Global domination of course.

What is Reform?
Reform is a right-wing, populist party led by Nigel Farage, a former MEP who won a seat in the House of Commons last year at his eighth attempt and a prominent figure in the campaign for the UK to leave the European Union.
It was founded in 2018 and originally called the Brexit Party.
Many of its members previously belonged to UKIP or the mainstream Conservatives.
After Brexit took place, the party focused on the reformation of British democracy.
Former Tory deputy chairman Lee Anderson became its first MP after defecting in March 2024.
The party gained support from Elon Musk, and had hoped the tech billionaire would make a £100m donation. However, Mr Musk changed his mind and called for Mr Farage to step down as leader in a row involving the US tycoon's support for far-right figurehead Tommy Robinson who is in prison for contempt of court.
Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”
