In the midst of a record-breaking heatwave in Europe, the UK city of Exeter recently played host to the second international conference on “tipping points”.

The event was billed as a “call to action” to the “research community, policymakers and business to raise awareness and understanding of the importance of tipping points and to accelerate the required action”.

As human activity drives global temperatures to record highs, multiple parts of the Earth system are at risk of being pushed beyond thresholds that would see them shift irreversibly into a new state.

The conference also focused heavily on “positive tipping points”, where large-scale, self-propelling social change can reduce the impact of humans on the climate.

Hosted jointly by the Global Systems Institute at the University of Exeter, the Potsdam Institute for Climate Impact Research and the Max Planck Institute of Geoanthropology, the conference was the second event dedicated to global tipping points, following the first in 2022.

A statement issued by conference convenors – and endorsed by hundreds of delegates – warned that the window for preventing tipping points is “rapidly closing”.

It called for “immediate, unprecedented action from policymakers worldwide and especially from leaders” at the forthcoming COP30 climate talks in Brazil.

The meeting was part of a week-long Exeter Climate Forum, which also included a separate Climate Conference and a series of community and business-focused events.

In this article, Carbon Brief draws together some of the key talking points, new research and ideas that emerged from the four-day event.

Climate tipping points

As he opened the conference, Prof Tim Lenton – director of the University of Exeter’s Global Systems Institute and one of three convenors of the event – introduced tipping points and set out the direction of the upcoming four days of talks.

He explained that tipping points are caused by “amplifying feedbacks” in a system becoming “self propelling”. He said these systems are “very hard to reverse and it could be quite abrupt”.

Lenton warned that since the last tipping points conference in 2022, global temperatures have risen, bringing many Earth system tipping points closer.

However, he told the conference that not all tipping points are harmful, distinguishing between a “bad tipping point in the climate or a positive one in societies and technologies”.

Lenton told the conference that “there is a compelling case that we could accelerate out of trouble”, adding that we could “lift [many people] out of harm” by focusing on positive tipping points.

Prof Johan Rockström, director of the Potsdam Institute for Climate Impact Research (PIK) and joint convenor of the conference, talked about the importance of considering planetary boundaries in tipping-points research. This framework sets out nine interlinked thresholds that would ensure a “safe operating space for humanity”.

Rockström told the conference that using this “whole Earth approach” can highlight that thresholds for tipping points may be lower than when only considering climate change.

For example, he said the Amazon rainforest is at risk of crossing a tipping point that could trigger “dieback” at around 3-5C of global warming above pre-industrial levels. However, he said that “transgressing” other thresholds, such as deforestation and moisture levels, could cause the system to tip sooner.

Rockström also argued that Earth system risks have now reached the “global catastrophic” level – defined by the Global Challenges Foundation as an event or process that “would kill or seriously harm more than 10% of the human population”.

He said the collapse of the Greenland and West Antarctic ice sheets, the dieback of the Amazon rainforest and the shutdown of the Atlantic Meridional Overturning Circulation (AMOC) present the greatest risk, as they have a high severity of impact and probability of occurrence.

He closed by arguing that scientists need to better communicate the risks of tipping points to encourage more action.

Prof Ricarda Winkelmann, the third convenor of the conference and professor of climate system analysis at PIK, discussed tipping of the Greenland and West Antarctic ice sheets, which together hold enough ice to raise global sea levels by 65 metres.

Winkelmann encouraged the delegates to consider timescales. She described tipping of the ice sheets as “slow-onset systems”, but highlighted that they can also “undergo quick and abrupt changes”.

To demonstrate this, she played a video of “calving” from the Ilulissat glacier in western Greenland. This was the largest calving ever caught on camera, which saw chunks of ice up to 1,000-metres thick break off the main ice sheet, she said.

Winkelmann described a “time clash” between the long-term changes in biophysical systems and short-term changes in socioeconomic systems. She concluded:

“The choices and actions implemented in this decade really have impacts now and also for the next 1,000 years.”

Also in the opening plenary session, Dr Carlos Nobre, a former Earth system scientist at the University of São Paulo, discussed tipping in the Amazon rainforest.

He said that decades of “high-level deforestation and degradation” across the Amazon have resulted in “much less water recycling”, as well as droughts and forest fires, that are creating a “tremendous health problem” for people.

Nobre noted that higher levels of deforestation push down the temperature threshold at which the rainforest could tip from lush rainforest to dry savannah.

He also discussed “nature-based solutions” and the importance of combining scientific knowledge with Indigenous knowledge and local communities.

Dr David Obura, the founding director of CORDIO East Africa and chair of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), highlighted the importance of the IPBES framing, which emphasises the need to connect nature and people.

He flagged the state of the world’s coral reefs, telling delegates that, as of the end of last year, 44% of the 800 coral reef species studied by the International Union for Conservation of Nature (IUCN) are “threatened”.

Obura added that “ocean temperatures have shot up in the last few years”. However, he warned that looking at temperature alone is insufficient, arguing that there are other physical and socioeconomic factors that need to be understood.

In the panel discussion that followed, Nobre stressed the importance of the COP30 talks in Brazil this year “looking at solutions” to the changing climate. Obura said that humanity has “extracted wealth from nature into economic systems”, arguing that this money must “come back into nature”.

When asked why the risk of tipping points is not being discussed at the UN security council, Rockström flagged an “inability to handle timescales” and said that language around uncertainty allows politicians to “kick the can down the road”.

When asked about the media, Rockström said it is “unfortunate” that humanity is allowing a media landscape that “underplays risk” and allows only “soundbites” from scientists. He added that the “media has a huge responsibility” in the current framing of climate change.

However, Winkelmann said the media “can play an incredibly important role in moving things forward”.

Broader focus

While the central themes of the 2022 conference were the two main areas of climate tipping points and positive tipping points, the 2025 event took a broader focus that encompassed social systems and governance.

Prof Winkelmann told Carbon Brief that this reflected how the tipping points “community” is much larger now than it was three years ago:

“The community has grown a lot since [2022] and it especially also includes not just the scientific community, both on the biophysical side and the social side, but also a lot of people from policy, governance and business. So I think it is really brilliant to have this community here together, thinking about tipping dynamics and the impacts in this holistic approach.”

Lenton told Carbon Brief the conference was “bigger and more diverse” than the 2022 edition. This, he said, was likely due to “demand for knowledge of the subject”, alongside a wider range of “stakeholders, voices and actors” being engaged in discussions about tipping points.

While tipping points are well-defined in natural sciences, they are less so in the social sciences, Rockström told Carbon Brief:

“I would even argue that many social scientists – even some social scientists at this conference – are even uncomfortable in using the term social tipping point, or positive tipping point, and are much more academically grounded in defining ‘social transformations’, ‘social transitions’ or ‘social change’. I have a strong respect for that. It is really important to humbly recognise that the social sciences come at this with very different methods and theories.”

In a plenary session on social-ecological tipping points, Dr Patricia Pinho – deputy science director at the Amazon Environmental Research Institute (IPAM) – argued that “we can’t really model forest resilience if we ignore the people that are on the frontline”.

According to her presentation, “Indigenous and traditional communities are already experiencing and resisting socio-ecological tipping points”.

Global warming and land-use change have led to forest degradation in 36% of the region, Pinho said. Combined with increasing forest fires, heat and drought, communities are seeing impacts on “food security, health [and] loss of biodiversity”, she added:

“So what we are seeing is loss of identity, place, attachment. People are losing their relationship [with the Amazon] and livelihoods and culture.”

Another plenary considered the positive tipping points in “socio-technical systems”.

Among the talks, Simon Sharpe, former deputy director of the UK government’s COP26 unit and now managing director of the non-profit research group S-Curve Economics, outlined the progress towards positive tipping points in the sectors of power generation, road transport and steel production.

While the power-sector transition is “going quite well” and light road transport is already seeing electric vehicles (EVs) make up “20% of new car sales globally”, the steel transition is in its “very early stages”, Sharpe explained.

For the steel industry, the “tipping point that we have to cross is in terms of risk perception”, Sharpe said:

“You have to get to the point where industry feels that actually it’s no longer the ‘first-mover risk’ that is the biggest risk – it’s the ‘late-mover risk’ that’s the biggest risk.”

Sharpe argued that this was best achieved by a clean-steel subsidy, noting that “we’ve seen for the brief period where the US had its [Inflation Reduction Act] and was strongly subsidising clean industrial production”. He continued:

“That resulted in a big shift of industry lobbying in Japan and the EU, where all the steel companies suddenly said, ‘Oh, can we have clean-steel subsidies as well, please?’”

Focusing specifically on EVs, Dr Jean-Francois Mercure from the University of Exeter described his forthcoming study on the tipping point “that is unfolding now”.

This has been driven by a feedback loop between the falling cost of EVs and the rise in how many are being purchased, Mercure explained:

“The cost coming down helps people buy more electric vehicles; more electric vehicles [being bought] causes the cost to come down.”

While there is “exponential growth” in EV sales, Mercure showed how the sales market share in conventional cars has been “plunging” in “Germany, UK, France and especially China” since 2019:

“So we’re kind of saying, yes, the system has started to tip into this new electric vehicle regime.”

However, Mercure added, “it’s fragile” as it could be bogged down by policy reversals. He also noted that there are barriers, such as China’s dominance in producing batteries, which is “becoming problematic” and led to tariffs in the EU and US.

From the audience, Prof Joyeeta Gupta of the University of Amsterdam questioned whether EVs are seeing a “long-term” tipping point when the global south is considered:

“Electric cars are going up the global north, but the old petrol cars are going south. Basically, what you’re seeing is that when certain things improve in the global north, the older stuff just gets dumped on the global south.”

Governance

The conference also emphasised the importance of governance, with multiple breakout sessions and a plenary dedicated to the topic.

In one breakout session, author Herb Simmens explained that governance is a “system of rules, processes and practices by which public institutions are managed and controlled”, which aim to “establish how decisions are to be made, and then to ensure that those responsible for making them do so”.

He argued that setting out to limit tipping points should be considered policymaking, not governance. However, he said that strong global governance is needed in order to oversee the implementation of policies to stop global warming. He also added that local governance is needed in many instances – for example, to stop deforestation in the Amazon in order to prevent the rainforest from tipping.

Dr Manjana Milkoreit – a postdoctoral researcher at the University of Oslo – chaired a plenary session on governance. She told delegates that the 2023 tipping points report identifies “two major domains of governance involved” in managing global tipping points. These are “prevention” and “reorganisation”, she said.

Sandrine Dixson-Decleve, co-president of the not-for-profit Club of Rome, stressed the importance of discussing how to “integrate planetary emergency at the top level into constitutional law”. She concluded:

“If we can’t get the governance to work right now, we have to think about other types of governance frameworks at the local level, community level, that start to create the feedback loop all the way back up to the international level.”

Durwood Zaelke, founder and president of the Institute for Governance & Sustainable Development, highlighted the success of the Montreal Protocol – an agreement signed in 1987 by nearly 200 countries to limit emissions of “ozone-depleting substances” in an effort to stem the damage to the ozone layer.

He argued that governance on cutting emissions must be binding, as the Montreal Protocol was, rather than voluntary.

He also argued that cutting CO2 emissions is “essential, but a slow process” and advocated for more emphasis on cutting emissions of “short-lived super-pollutants”.

Prof Per Olsson, deputy science director at the Stockholm Resilience Centre, said there has been a “deeply problematic” backlash in the past five years, in the form of “political polarisation”, “war”, “democratic backsliding” and the “dehumanisation of people that think differently from you”. He warned that these “threaten to derail many processes”.

Oliver Morton is a senior editor at the Economist and serves on the board of trustees of the Degrees Initiative – a non-government organisation that focuses on promoting expertise on solar radiation management in the global south. (However, he said at the start of his talk that he was not speaking in these capacities.)

Morton argued for a greater emphasis on solar geoengineering in the tipping points community.

Morton told delegates that the lengthy 2023 global tipping points report featured only a few paragraphs on solar geoengineering, stating that the technology “might” help limit temperature rise, he said:

“I would really be interested in that ‘might’. But that’s not, in fact, what this community does. It’s not what people particularly seem to want to talk about.”

Morton noted that many delegates of the recent Arctic Repair Conference, which was held in Cambridge in June, were present at the tipping points conference, highlighting the “overlap” between the two fields.

He recognised the challenges with the governance of solar geoengineering, but added that there are challenges “for all governance”. He also emphasised that “everyone in the solar geoengineering community” says that the technology would “complement, not replace, mitigation”.

Morton emphasised the need for expertise on solar geoengineering in the global south. He concluded that “sidelining” research on geoengineering, which potentially could reduce harm, opens up the tipping-points community to criticism for not considering all options. He referred to this as “choice-editing”.

Finally, Prof Joyeeta Gupta, spoke about the divide between the global north and global south.

She said that she is working to introduce a global constitution “to try to understand how to regulate the public and private sector” and she invited the audience to participate by sending in submissions.

When asked whether the phrase “tipping points” has been watered down, Sandrine said that words like “regenerative” and “sustainable development” are overused and agreed that we “can’t keep playing with the language until it becomes nonsensical”. She called on conference delegates to come together to define key terms.

At a breakout session, Prof Karen Morrow, a professor of environmental law at Swansea University, explained that the legal system currently does not deal well with any issue at the planetary scale, as global problems cannot be reduced to a “nice, tidy jurisdictional issue”.

She said that the irreversibility of Earth system tipping points is “horriffic”. However, she noted that the language of uncertainty in science can make it hard to “find a foothold” legally, arguing that the irreversibility may help with this by providing more certainty.

She added that there are currently laws around “obligation to prevent harm”, but said that there are “not enough”, arguing that we need laws that dictate a “substantive restraint on human activities”.

Positive tipping points

A significant portion of the conference was dedicated to “positive tipping points” – described to Carbon Brief by Rockström as “social transformations” that generate “feedbacks that are self-enforcing”, making them difficult to reverse.

Examples of these social transformations that featured in plenaries and research sessions included the rapid rollout of EVs in Norway, tree-planting schemes in Uganda, investments in “regenerative” cotton farming and the falling costs and rising adoption of solar energy around the world.

In a breakout session, Dr Jean-Francois Mercure said the “positive tipping point narrative is good because it changes the policy narrative”. He explained:

“We used to have this narrative, which goes – ‘we tax [and] we price the externality because prices need to reflect costs’. This is demanding because it is politically difficult to tax and subsidies need to be justified. [That narrative says] we are pushing a thing that gets harder the more we do it – so there is a limit to climate action.

“This is not how it really works. When you look at the solar revolution, we had to push up to a certain point, after which it went off on its own. Electric vehicles, too. This [narrative] changes what policymakers need to do and think. They need to work to push over the initial hurdle.”

In a plenary session, Kate Raworth, an ecological economist at the University of Oxford, highlighted how a growing number of states, cities and regions around the world had adopted her “doughnut” theory of economics.

Doughnut economics” is a framework which imagines a global economy which prioritises meeting the needs of people without overshooting planetary boundaries.

Raworth highlighted how more than 50 municipal governments had publicly adopted the framework since 2019 – and added there are “another 50 doing it behind the scenes”. She said that “peer-to-peer inspiration” has been a powerful force in driving momentum behind the framework’s popularity.

Jameela Mahmood, executive director of the Sunway Centre for Planetary Health at Sunway University in Kuala Lumpur, described how her organisation’s advocacy had led to the Malaysian government’s adoption of a planetary health framework in its forthcoming economic development plan. She also said planetary health would become a mandatory part of the nation’s undergraduate curriculum from 2026.

Túlio Andrare, chief strategy and alignment officer for the COP30 presidency, described the Brazilian government’s plans to convene a “global mutirão”, which encourages individuals, communities and organisations to make self-determined commitments to take actions to tackle climate change. (Mutirão is a word from the Indigenous Tupi-Guarani language family that refers to collective action). He said:

“The global mutirão is about inviting people to think about who they are and what they can offer. It is also about designing potential positive tipping points. Because if we have different initiatives that are self-organised, we can integrate those local initiatives in a global framework.”

In a separate plenary session on tipping points within food systems, Rune Baastrup, director of development at Democracy X, a private foundation focused on deliberate democracy, presented on a project to shift eating habits in Denmark.

The project, which he said is grounded in “sociological literature”, is to encourage a push towards plant-based eating from a local level, by funding and coordinating communal meals that citizens arrange for and with each other. Baastrup explained:

“It’s not about politicians going out pointing fingers at citizens. It is about citizens engaging and then mobilising each other – not necessarily because they want to save the world, but because they want to do interesting and cool things with their neighbours.”

According to Democracy X’s theory of change, reaching “one in 10 Danes” through this work would be enough to galvanise a “profoundly more deep green transition” in the Scandinavian country, Baastrup said.

In the same session, journalist and author George Monbiot said it was “questionable” whether the global food system could achieve a “positive tipping point”.

However, he said there were a number of actions that could be taken to create a food system which maintains high yields, reduces environmental impacts while remaining diversified and leaving space for nature restoration and recovery. He argued that these included: switching away from an animal-based diet to a plant-based diet; the embrace of perennial grain and arable crops; and production of food outside the farming system, including through precision fermentation.

Monbiot said the conversation around food systems was “going backwards”, pointing to the growing popularity of “simple living, grow-your-own soul food” tropes on social media:

“There is this complete confusion between what looks nice – between the bucolic, romantic, aesthetic and cottagecore that you can post up on Instagram – and what we actually need in order to intervene effectively in this huge Leviathan of a system which is going to crush us into dust.”

In his closing remarks, Lenton mused that the research community was on a quest to discover the “recipe” behind positive tipping points. He explained:

“We’re passionate as researchers to seek out the early opportunity signals that systems we want to get rid of might be able to get tipped out of.”

Having a toolkit for identifying the “generic” signals of when an incumbent system is showing signs of destabilising could guide efforts from activists, policymakers and investors to drive positive change for the planet, he said.

Lenton said upcoming research, set to be published in Sustainability Science, represented a “first attempt” at a methodology “for anyone who wants to ask whether a system has the potential for a positive tipping”. The methodology in question would also seek to answer the following questions, he said:

“If [a system] has [the potential to tip], how close is it? What factors would influence it? In particular, what could bring it forward? And then what actions could influence those factors to tip other systems?”

Lenton urged scientists at the conference to help him “refine and apply” the methodology. He also urged colleagues to keep “documenting” evidence of positive tipping over the years ahead. He explained:

“There is a theory of change here. We have got to enable each other to learn faster [and] to spread these initiatives better.”

New science

Modelling projects

Along with the main plenaries, the conference included around 50 breakout meetings, split between “research sessions” and “action workshops”.

Among the new research being presented at these sessions were early results from the “TIPMIP” international modelling project.

Rockström told Carbon Brief the “biggest change” in tipping-points science since the first conference in 2022 is the launch of TIPMIP. He said:

“The most solid scientific basis in the IPCC are all the ‘MIPs’, the modelling comparison programmes. The biggest one is CMIP [the Coupled Model Intercomparison Project], which gives us the data and the scenarios to be able to deliver the Paris Agreement.

“Now, we finally have a MIP for tipping points – and the tipping point comparison community is here at the conference, as well as [scientists from] the big Earth system models. Big tipping modelling analysis [is underway] on AMOC risks, on the Amazon rainforest, on permafrost and the ice sheets. That is a major advancement.”

Dr Jeremy Walton, who leads the software engineering team for the UK Earth System Model at the Met Office Hadley Centre, kicked off one research session by unpacking the Earth system modelling “experiment protocol” within TIPMIP. This is a “framework for the modelling and investigation of climate overshoot and tipping points”, he explained, which sets out a consistent set of “idealised” – or simplified – experiments for scientists to conduct in order to build up a large dataset of results from lots of climate models.

The figure below illustrates these experiments, which include control runs with no global warming (black line), runs where warming is stabilised, such as at 2C or 4C (green lines) and further runs where warming is subsequently reduced via carbon removal (blue lines).

In all cases, warming first “ramps up” at a rate of 0.2C per decade “because that matches the observed rate in recent years”, Walton said.

Antarctica

Prof Colin Jones from the University of Leeds presented some initial results from the idealised experiments for the Antarctic ice sheet, carried out by Dr Sophy Oliver of the National Oceanography Centre in Southampton.

The analysis focuses on the massive Ross and Filchner-Ronne ice shelves, which float on the ocean and hold back land ice behind them. At the moment, Jones explained, they are both “cold-water cavities”, in that the ocean water beneath the shelves is “below the freezing point of sea ice”. However, if they “tip” to “switch to being warm-water cavities, then there’s a risk for rapid loss of ice”, he said.

The switch happens because melting of Antarctic ice adds freshwater beneath the ice shelves. This reduces the “density barrier” between the cavity and warmer open ocean, said Jones, reaching a “sudden point where the salinity is sufficiently low that the density has changed and it allows open ocean water” to get into under the ice shelves.

Their model runs suggest that there is a “danger zone” for the Ross ice shelf of around 3.5-4C, Jones said:

“If you go more than 4C, it will always tip [in model runs]…If you stay below about 3C, it will never tip.”

For the Filchner-Ronne ice shelf, “it is basically the same mechanism, but it happens at a higher warming level”, noted Jones, with a “danger zone” around 5-5.5C.

Also focusing on Antarctica, Sacha Sinet from Utrecht University presented analysis on the interactions between AMOC and the polar ice sheets, with results suggesting that the loss of the Antarctic ice sheet could actually stabilise the AMOC and prevent it from collapsing.

Sinet’s research is currently being reviewed before potential publication.

Another study on Antarctica was published on the opening day of the tipping points conference. The research, led by Dr Alessadro Silvano from the National Oceanography Centre, uses satellite data to reveal a marked increase in surface salinity across the Southern Ocean since 2015, coinciding with a “dramatic decline” in Antarctic sea ice.

The findings suggest that the Southern Ocean “might have entered a new system”, Silvano said. He explained how he has been observing an increase in salinity in the top 100 metres of the ocean. This is “counterintuitive”, he said, as “you think the more melting of ice, then you should freshen the ocean instead”.

The increase is because the ocean is becoming “less stratified”, meaning that warm water – which is also more salty – is “able to reach the surface of the ocean more”, making is harder for sea ice to regrow. he explained:

“And this is circumpolar. So it’s happening everywhere you see the increase in salinity.”

This has the potential to drive a self-reinforcing feedback loop, Silvano wrote in an article for the Conversation:

“We may have passed a tipping point and entered a new state defined by persistent sea ice decline, sustained by a newly discovered feedback loop.”

When asked by an audience member whether solar geoengineering could help, Silvano noted: “The problem for Antarctica is that melting is driven by the ocean. You cannot stop warming in the ocean, so that, to me, is an impossible task.”

Ecological shifts

Away from Antarctica, Dr Bette Otto-Bliesner of the US National Center for Atmospheric Research introduced another “MIP” – the What If Modeling Intercomparison Project (WhatIfMIP), which aims to investigate the consequences of what happens if a tipping point is crossed.

In particular, the programme will look at the cascading effects of one tipping element on another, including Amazon dieback, shifts in boreal forests, AMOC collapse, permafrost loss and the collapse of the Greenland and West Antarctic ice sheets, Otto-Bliesner explained.

One area of focus will be on the potential implications of “Sahel greening”, Otto-Bliesner said:

“We don’t think the Sahara is going to green in the next few centuries. But there is a project in the Sahel region called the Great Green Wall Initiative, where they’re actually planting trees. They’ve already started this…So what are the consequences of that, in terms of precipitation, drought, but also…heatwaves?”

In another talk, Caroline Wallington – from the Centre for Sustainability Transitions at Stellenbosch University in South Africa – presented a global analysis of ecosystems and people at risk of 21 different ecological “regime shifts”.

The findings show that 26% of the global land area is at risk of at least one ecological shift, covering 3.4 billion people, or 43% of the global population.

Around 31% of corals are at risk of a regime shift, Wallington said, while 30% of tundra is at risk from a transition to boreal forest and 28% of tropical forests are at risk of tipping into savannah.

The regions of the world at highest risk include the south Pacific, south-east Asia and central America, Wallington noted. Some of the most populous countries in the world are at risk from these regime shifts, she added, including China, India, the US and Indonesia.

Paris limits

Dr Nico Wunderling, from the Center for Critical Computational Studies at Goethe University Frankfurt and the Potsdam Institute for Climate Impact Research, presented on how tipping point risks are affected by “overshooting” temperature goals, such as the Paris Agreement’s 1.5C limit.

His work indicates that “tipping risks are even non-negligible now at global warming levels of 1.3-1.5C”, while overshooting 2C would mean “entering a very high risk zone for climate tipping elements”.

Wunderling presented some early results – currently undergoing peer review – on how the risk of Amazon dieback depends on both the levels of warming and deforestation.

When only warming is considered, current pathways to 2.7-2.8C above pre-industrial levels “seem to still relatively keep the Amazon rainforest at a safe level”, he said. However, he added, when deforestation is included, tipping risks become much closer – “to levels that are well within the Paris Agreement, so about 1.5-2C”.

Wunderling recently wrote a Carbon Brief guest post on “cascading” tipping points, indicating that the “majority of interactions between tipping elements will lead to further destabilisation of the climate system”.

Where next?

In the closing plenary, Rockström confirmed that PIK would host a tipping points conference in Berlin in 2027.

He also revealed that plans were afoot to host a tipping points conference in 2026 in Malaysia, following discussions with Jameela Mahmood of the Sunway Centre for Planetary Health in Kuala Lumpur.

Rockström said this reflected the need to host the conference in the global south and the importance of “building momentum” around tipping point risks and opportunities.

He added that the Malaysia-hosted conference could be held “in connection” with the COP31 climate summit, should Australia’s bid to host the UN talks in 2026 prove successful.

Meanwhile, a second global tipping points report is earmarked for the latter half of 2025.

(Carbon Brief covered the first global tipping point report in 2023).

Lenton told Carbon Brief the upcoming report will be “tighter” than its predecessor and “major” on governance issues.

Explaining the rationale for giving governance top billing in the report, Lenton said:

“We want to lead on the things we need. We clearly need some improvements in governance and institutions to get on top of both the tipping point risks and, arguably, the opportunities. Everyone can see that – it has been repeated several times already at this meeting. So, it is important to be clear what differences [governance] makes and what different kinds of governance we are calling for.”

The report will also offer an “update on tipping point risks and opportunities”, Lenton said, and include three case studies looking at Earth system tipping points – the shutdown of AMOC, Amazon dieback and coral die-off. It will also feature one “localised” example of a glacier tipping point and its consequences.

The case studies are designed to provide “more specific and concrete guidance” on how to avoid tipping risks, according to Lenton.

In addition, Ricarda Winkelmann told Carbon Brief that she and her colleagues will be answering a “call on the scientific community to put together a robust risk assessment on tipping dynamics”. This will involve “creating a first global atlas of tipping financial risks”, she explained – in time to feed into the seventh assessment report (AR7) of the Intergovernmental Panel on Climate Change (IPCC).

Discussing AR7 with Carbon Brief, Rockström said he was “very disappointed” that, at a meeting last year, countries decided not to include a special report on tipping points in the IPCC’s AR7 cycle.

This happened because the topic “makes policymakers and some member countries around the world very uncomfortable”, Rockström said.

Despite the “illogical” decision, the AR7 assessment reports will “see much more tipping-point science”, added Rockström, “for the simple reason that we have TIPMIP [and] we have a much broader community now – it’s entering the mainstream of Earth system modelling”.

This is “so important” in order to narrow uncertainty ranges in projections of tipping points, Rockström argued:

“I am of the view that one reason why we’re not acting faster on the climate crisis – one of many reasons – one fundamental reason is that we in the scientific community are not able to communicate precision on risk.

“Science on tipping point risk is so important because so many actors are using the uncertainty ranges as an excuse for not acting. So, as long as the AMOC continues to have medium confidence, then you can go on forever kicking the can down the road.”

The Exeter meeting comes against a backdrop of cuts to climate science funding in the US, including to the budget of the National Oceanic and Atmospheric Administration (NOAA).

Lenton said the tipping-point community was “traumatised” by the developments – “especially [on behalf] of colleagues in the US” who had lost their jobs. He added:

“It is already influencing things. If we lose NOAA and we lose our state-of-the-art assessment of the state of the oceans – these are dangerous erosions of our ability to sense whether the Earth system is destabilising or not. This is a fundamental loss.”

During the conference, the convenors drafted a conference statement, which they encouraged delegates to endorse.

With global warming approaching the Paris Agreement 1.5C limit, the statement warns that this places “humanity in the danger zone where multiple climate tipping points pose catastrophic risks to billions of people”.

It says that the “window for preventing these cascading climate dynamics is rapidly closing”, adding:

“We join the COP30 presidency in calling on governments to enact policies that help trigger positive tipping points in their economies and societies, which generate self-propelling change in technologies and behaviours towards zero emissions.”

The statement concludes by arguing that “decisive policy and civil society action” is needed for the world to “tip its trajectory from facing unmanageable climate tipping point risks to seizing positive tipping point opportunities”.

DeBriefed 27 February 2026: Trump’s fossil-fuel talk | Modi-Lula rare-earth pact | Is there a UK ‘greenlash’? 

Published

on

Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.

This week

Absolute State of the Union

‘DRILL, BABY’: US president Donald Trump “doubled down on his ‘drill, baby, drill’ agenda” in his State of the Union (SOTU) address, said the Los Angeles Times. He “tout[ed] his support of the fossil-fuel industry and renew[ed] his focus on electricity affordability”, reported the Financial Times. Trump also attacked the “green new scam”, noted Carbon Brief’s SOTU tracker.

COAL REPRIEVE: Earlier in the week, the Trump administration had watered down limits on mercury pollution from coal-fired power plants, reported the Financial Times. It remains “unclear” if this will be enough to prevent the decline of coal power, said Bloomberg, in the face of lower-cost gas and renewables. Reuters noted that US coal plants are “ageing”.

OIL STAY: The US Supreme Court agreed to hear arguments brought by the oil industry in a “major lawsuit”, reported the New York Times. The newspaper said the firms are attempting to head off dozens of other lawsuits at state level, relating to their role in global warming.

SHIP-SHILLING: The Trump administration is working to “kill” a global carbon levy on shipping “permanently”, reported Politico, after succeeding in delaying the measure late last year. The Guardian said US “bullying” could be “paying off”, after Panama signalled it was reversing its support for the levy in a proposal submitted to the UN shipping body.

Around the world

  • RARE EARTHS: The governments of Brazil and India signed a deal on rare earths, said the Times of India, as well as agreeing to collaborate on renewable energy.
  • HEAT ROLLBACK: German homes will be allowed to continue installing gas and oil heating, under watered-down government plans covered by Clean Energy Wire.
  • BRAZIL FLOODS: At least 53 people died in floods in the state of Minas Gerais, after some areas saw 170mm of rain in a few hours, reported CNN Brasil.
  • ITALY’S ATTACK: Italy is calling for the EU to “suspend” its emissions trading system (ETS) ahead of a review later this year, said Politico.
  • COOKSTOVE CREDITS: The first-ever carbon credits under the Paris Agreement have been issued to a cookstove project in Myanmar, said Climate Home News.
  • SAUDI SOLAR: Turkey has signed a “major” solar deal that will see Saudi firm ACWA building 2 gigawatts in the country, according to Agence France-Presse.

Captured

The constituency of Richard Tice MP, the climate-sceptic deputy leader of Reform UK, is the second-largest recipient of flood defence spending in England, according to new Carbon Brief analysis. Overall, the funding is disproportionately targeted at coastal and urban areas, many of which have Conservative or Liberal Democrat MPs.

Spotlight

Is there really a UK ‘greenlash’?

This week, after a historic Green Party byelection win, Carbon Brief looks at whether there really is a “greenlash” against climate policy in the UK.

Over the past year, the UK’s political consensus on climate change has been shattered.

Yet despite a sharp turn against climate action among right-wing politicians and right-leaning media outlets, UK public support for climate action remains strong.

Prof Federica Genovese, who studies climate politics at the University of Oxford, told Carbon Brief:

“The current ‘war’ on green policy is mostly driven by media and political elites, not by the public.”

Indeed, there is still a greater than two-to-one majority among the UK public in favour of the country’s legally binding target to reach net-zero emissions by 2050, as shown below.

Steve Akehurst, director of public-opinion research initiative Persuasion UK, also noted the growing divide between the public and “elites”. He told Carbon Brief:

“The biggest movement is, without doubt, in media and elite opinion. There is a bit more polarisation and opposition [to climate action] among voters, but it’s typically no more than 20-25% and mostly confined within core Reform voters.”

Conservative gear shift

For decades, the UK had enjoyed strong, cross-party political support for climate action.

Lord Deben, the Conservative peer and former chair of the Climate Change Committee, told Carbon Brief that the UK’s landmark 2008 Climate Change Act had been born of this cross-party consensus, saying “all parties supported it”.

Since their landslide loss at the 2024 election, however, the Conservatives have turned against the UK’s target of net-zero emissions by 2050, which they legislated for in 2019.

Curiously, while opposition to net-zero has surged among Conservative MPs, there is majority support for the target among those that plan to vote for the party, as shown below.

Dr Adam Corner, advisor to the Climate Barometer initiative that tracks public opinion on climate change, told Carbon Brief that those who currently plan to vote Reform are the only segment who “tend to be more opposed to net-zero goals”. He said:

“Despite the rise in hostile media coverage and the collapse of the political consensus, we find that public support for the net-zero by 2050 target is plateauing – not plummeting.”

Reform, which rejects the scientific evidence on global warming and campaigns against net-zero, has been leading the polls for a year. (However, it was comfortably beaten by the Greens in yesterday’s Gorton and Denton byelection.)

Corner acknowledged that “some of the anti-net zero noise…[is] showing up in our data”, adding:

“We see rising concerns about the near-term costs of policies and an uptick in people [falsely] attributing high energy bills to climate initiatives.”

But Akehurst said that, rather than a big fall in public support, there had been a drop in the “salience” of climate action:

“So many other issues [are] competing for their attention.”

UK newspapers published more editorials opposing climate action than supporting it for the first time on record in 2025, according to Carbon Brief analysis.

Global ‘greenlash’?

All of this sits against a challenging global backdrop, in which US president Donald Trump has been repeating climate-sceptic talking points and rolling back related policy.

At the same time, prominent figures have been calling for a change in climate strategy, sold variously as a “reset”, a “pivot”, as “realism”, or as “pragmatism”.

Genovese said that “far-right leaders have succeeded in the past 10 years in capturing net-zero as a poster child of things they are ‘fighting against’”.

She added that “much of this is fodder for conservative media and this whole ecosystem is essentially driving what we call the ‘greenlash’”.

Corner said the “disconnect” between elite views and the wider public “can create problems” – for example, “MPs consistently underestimate support for renewables”. He added:

“There is clearly a risk that the public starts to disengage too, if not enough positive voices are countering the negative ones.”

Watch, read, listen

TRUMP’S ‘PETROSTATE’: The US is becoming a “petrostate” that will be “sicker and poorer”, wrote Financial Times associate editor Rana Forohaar.

RHETORIC VS REALITY: Despite a “political mood [that] has darkened”, there is “more green stuff being installed than ever”, said New York Times columnist David Wallace-Wells.
CHINA’S ‘REVOLUTION’: The BBC’s Climate Question podcast reported from China on the “green energy revolution” taking place in the country.

Analysis: Constituency of Reform’s climate-sceptic Richard Tice gets £55m flood funding

Published

on

The Lincolnshire constituency held by Richard Tice, the climate-sceptic deputy leader of the hard-right Reform party, has been pledged at least £55m in government funding for flood defences since 2024.

This investment in Boston and Skegness is the second-largest sum for a single constituency from a £1.4bn flood-defence fund for England, Carbon Brief analysis shows.

Flooding is becoming more likely and more extreme in the UK due to climate change.

Yet, for years, governments have failed to spend enough on flood defences to protect people, properties and infrastructure.

The £1.4bn fund is part of the current Labour government’s wider pledge to invest a “record” £7.9bn over a decade on protecting hundreds of thousands of homes and businesses from flooding.

As MP for one of England’s most flood-prone regions, Tice has called for more investment in flood defences, stating that “we cannot afford to ‘surrender the fens’ to the sea”.

He is also one of Reform’s most vocal opponents of climate action and what he calls “net stupid zero”. He denies the scientific consensus on climate change and has claimed, falsely and without evidence, that scientists are “lying”.

Flood defences

Last year, the government said it would invest £2.65bn on flood and coastal erosion risk management (FCERM) schemes in England between April 2024 and March 2026.

This money was intended to protect 66,500 properties from flooding. It is part of a decade-long Labour government plan to spend more than £7.9bn on flood defences.

There has been a consistent shortfall in maintaining England’s flood defences, with the Environment Agency expecting to protect fewer properties by 2027 than it had initially planned.

The Climate Change Committee (CCC) has attributed this to rising costs, backlogs from previous governments and a lack of capacity. It also points to the strain from “more frequent and severe” weather events, such as storms in recent years that have been amplified by climate change.

However, the CCC also said last year that, if the 2024-26 spending programme is delivered, it would be “slightly closer to the track” of the Environment Agency targets out to 2027.

The government has released constituency-level data on which schemes in England it plans to fund, covering £1.4bn of the 2024-26 investment. The other half of the FCERM spending covers additional measures, from repairing existing defences to advising local authorities.

The map below shows the distribution of spending on FCERM schemes in England over the past two years, highlighting the constituency of Richard Tice.

The government notes that, as Environment Agency accounts have not been finalised and approved, the investment data is “provisional and subject to change”. Some schemes cover multiple constituencies and are not included on the map. Source: Environment Agency FCERM data.

By far the largest sum of money – £85.6m in total – has been committed to a tidal barrier and various other defences in the Somerset constituency of Bridgwater, the seat of Conservative MP Ashley Fox.

Over the first months of 2026, the south-west region has faced significant flooding and Fox has called for more support from the government, citing “climate patterns shifting and rainfall intensifying”.

He has also backed his party’s position that “the 2050 net-zero target is impossible” and called for more fossil-fuel extraction in the North Sea.

Tice’s east-coast constituency of Boston and Skegness, which is highly vulnerable to flooding from both rivers and the sea, is set to receive £55m. Among the supported projects are beach defences from Saltfleet to Gibraltar Point and upgrades to pumping stations.

Overall, Boston and Skegness has the second-largest portion of flood-defence funding, as the chart below shows. Constituencies with Conservative and Liberal Democrat MPs occupied the other top positions.

Overall, despite Labour MPs occupying 347 out of England’s 543 constituencies – nearly two-thirds of the total – more than half of the flood-defence funding was distributed to constituencies with non-Labour MPs. This reflects the flood risk in coastal and rural areas that are not traditional Labour strongholds.

Reform funding

While Reform has just eight MPs, representing 1% of the population, its constituencies have been assigned 4% of the flood-defence funding for England.

Nearly all of this money was for Tice’s constituency, although party leader Nigel Farage’s coastal Clacton seat in Kent received £2m.

Reform UK is committed to “scrapping net-zero” and its leadership has expressed firmly climate-sceptic views.

Much has been made of the disconnect between the party’s climate policies and the threat climate change poses to its voters. Various analyses have shown the flood risk in Reform-dominated areas, particularly Lincolnshire.

Tice has rejected climate science, advocated for fossil-fuel production and criticised Environment Agency flood-defence activities. Yet, he has also called for more investment in flood defences, stating that “we cannot afford to ‘surrender the fens’ to the sea”.

This may reflect Tice’s broader approach to climate change. In a 2024 interview with LBC, he said:

“Where you’ve got concerns about sea level defences and sea level rise, guess what? A bit of steel, a bit of cement, some aggregate…and you build some concrete sea level defences. That’s how you deal with rising sea levels.”

While climate adaptation is viewed as vital in a warming world, there are limits on how much societies can adapt and adaptation costs will continue to increase as emissions rise.

Key developments

Food inflation on the rise

DELUGE STRIKES FOOD: Extreme rainfall and flooding across the Mediterranean and north Africa has “battered the winter growing regions that feed Europe…threatening food price rises”, reported the Financial Times. Western France has “endured more than 36 days of continuous rain”, while farmers’ associations in Spain’s Andalusia estimate that “20% of all production has been lost”, it added. Policy expert David Barmes told the paper that the “latest storms were part of a wider pattern of climate shocks feeding into food price inflation”.

NO BEEF: The UK’s beef farmers, meanwhile, “face a double blow” from climate change as “relentless rain forces them to keep cows indoors”, while last summer’s drought hit hay supplies, said another Financial Times article. At the same time, indoor growers in south England described a 60% increase in electricity standing charges as a “ticking timebomb” that could “force them to raise their prices or stop production, which will further fuel food price inflation”, wrote the Guardian.

TINDERBOX’ AND TARIFFS: A study, covered by the Guardian, warned that major extreme weather and other “shocks” could “spark social unrest and even food riots in the UK”. Experts cited “chronic” vulnerabilities, including climate change, low incomes, poor farming policy and “fragile” supply chains that have made the UK’s food system a “tinderbox”. A New York Times explainer noted that while trade could once guard against food supply shocks, barriers such as tariffs and export controls – which are being “increasingly” used by politicians – “can shut off that safety valve”.

El Niño looms

NEW ENSO INDEX: Researchers have developed a new index for calculating El Niño, the large-scale climate pattern that influences global weather and causes “billions in damages by bringing floods to some regions and drought to others”, reported CNN. It added that climate change is making it more difficult for scientists to observe El Niño patterns by warming up the entire ocean. The outlet said that with the new metric, “scientists can now see it earlier and our long-range weather forecasts will be improved for it.”

WARMING WARNING: Meanwhile, the US Climate Prediction Center announced that there is a 60% chance of the current La Niña conditions shifting towards a neutral state over the next few months, with an El Niño likely to follow in late spring, according to Reuters. The Vibes, a Malaysian news outlet, quoted a climate scientist saying: “If the El Niño does materialise, it could possibly push 2026 or 2027 as the warmest year on record, replacing 2024.”

CROP IMPACTS: Reuters noted that neutral conditions lead to “more stable weather and potentially better crop yields”. However, the newswire added, an El Niño state would mean “worsening drought conditions and issues for the next growing season” to Australia. El Niño also “typically brings a poor south-west monsoon to India, including droughts”, reported the Hindu’s Business Line. A 2024 guest post for Carbon Brief explained that El Niño is linked to crop failure in south-eastern Africa and south-east Asia.

News and views

  • DAM-AG-ES: Several South Korean farmers filed a lawsuit against the country’s state-owned utility company, “seek[ing] financial compensation for climate-related agricultural damages”, reported United Press International. Meanwhile, a national climate change assessment for the Philippines found that the country “lost up to $219bn in agricultural damages from typhoons, floods and droughts” over 2000-10, according to Eco-Business.
  • SCORCHED GRASS: South Africa’s Western Cape province is experiencing “one of the worst droughts in living memory”, which is “scorching grass and killing livestock”, said Reuters. The newswire wrote: “In 2015, a drought almost dried up the taps in the city; farmers say this one has been even more brutal than a decade ago.”
  • NOUVELLE VEG: New guidelines published under France’s national food, nutrition and climate strategy “urged” citizens to “limit” their meat consumption, reported Euronews. The delayed strategy comes a month after the US government “upended decades of recommendations by touting consumption of red meat and full-fat dairy”, it noted. 
  • COURTING DISASTER: India’s top green court accepted the findings of a committee that “found no flaws” in greenlighting the Great Nicobar project that “will lead to the felling of a million trees” and translocating corals, reported Mongabay. The court found “no good ground to interfere”, despite “threats to a globally unique biodiversity hotspot” and Indigenous tribes at risk of displacement by the project, wrote Frontline.
  • FISH FALLING: A new study found that fish biomass is “falling by 7.2% from as little as 0.1C of warming per decade”, noted the Guardian. While experts also pointed to the role of overfishing in marine life loss, marine ecologist and study lead author Dr Shahar Chaikin told the outlet: “Our research proves exactly what that biological cost [of warming] looks like underwater.” 
  • TOO HOT FOR COFFEE: According to new analysis by Climate Central, countries where coffee beans are grown “are becoming too hot to cultivate them”, reported the Guardian. The world’s top five coffee-growing countries faced “57 additional days of coffee-harming heat” annually because of climate change, it added.

Nature talks inch forward

This week, Carbon Brief covers the latest round of negotiations under the UN Convention on Biological Diversity (CBD), which occurred in Rome over 16-19 February.

The penultimate set of biodiversity negotiations before October’s Conference of the Parties ended in Rome last week, leaving plenty of unfinished business.

The CBD’s subsidiary body on implementation (SBI) met in the Italian capital for four days to discuss a range of issues, including biodiversity finance and reviewing progress towards the nature targets agreed under the Kunming-Montreal Global Biodiversity Framework (GBF).

However, many of the major sticking points – particularly around finance – will have to wait until later this summer, leaving some observers worried about the capacity for delegates to get through a packed agenda at COP17.

The SBI, along with the subsidiary body on scientific, technical and technological advice (SBSTTA) will both meet in Nairobi, Kenya, later this summer for a final round of talks before COP17 kicks off in Yerevan, Armenia, on 19 October.

Money talks

Finance for nature has long been a sticking point at negotiations under the CBD.

Discussions on a new fund for biodiversity derailed biodiversity talks in Cali, Colombia, in autumn 2024, requiring resumed talks a few months later.

Despite this, finance was barely on the agenda at the SBI meetings in Rome. Delegates discussed three studies on the relationship between debt sustainability and implementation of nature plans, but the more substantive talks are set to take place at the next SBI meeting in Nairobi.

Several parties “highlighted concerns with the imbalance of work” on finance between these SBI talks and the next ones, reported Earth Negotiations Bulletin (ENB).

Lim Li Ching, senior researcher at Third World Network, noted that tensions around finance permeated every aspect of the talks. She told Carbon Brief:

“If you’re talking about the gender plan of action – if there’s little or no financial resources provided to actually put it into practice and implement it, then it’s [just] paper, right? Same with the reporting requirements and obligations.”

Monitoring and reporting

Closely linked to the issue of finance is the obligations of parties to report on their progress towards the goals and targets of the GBF.

Parties do so through the submission of national reports.

Several parties at the talks pointed to a lack of timely funding for driving delays in their reporting, according to ENB.

A note released by the CBD Secretariat in December said that no parties had submitted their national reports yet; by the time of the SBI meetings, only the EU had. It further noted that just 58 parties had submitted their national biodiversity plans, which were initially meant to be published by COP16, in October 2024.

Linda Krueger, director of biodiversity and infrastructure policy at the environmental not-for-profit Nature Conservancy, told Carbon Brief that despite the sparse submissions, parties are “very focused on the national report preparation”. She added:

“Everybody wants to be able to show that we’re on the path and that there still is a pathway to getting to 2030 that’s positive and largely in the right direction.”

Watch, read, listen

NET LOSS: Nigeria’s marine life is being “threatened” by “ghost gear” – nets and other fishing equipment discarded in the ocean – said Dialogue Earth.

COMEBACK CAUSALITY: A Vox long-read looked at whether Costa Rica’s “payments for ecosystem services” programme helped the country turn a corner on deforestation.

HOMEGROWN GOALS: A Straits Times podcast discussed whether import-dependent Singapore can afford to shelve its goal to produce 30% of its food locally by 2030.

‘RUSTING’ RIVERS: The Financial Times took a closer look at a “strange new force blighting the [Arctic] landscape”: rivers turning rust-orange due to global warming.
