Since Donald Trump moved into the White House for his second term as president in January 2025, you’d be forgiven for thinking the US has abandoned all action to tackle climate change and is working aggressively to undermine the efforts of other countries towards that end.
This week, at the Spring Meetings of the International Monetary Fund and World Bank in Washington DC, US Treasury Secretary Scott Bessent cast doubt on the scientific consensus around global warming and pressured the two institutions to reverse what he called their “mission creep” and “myopic focus” on climate.
But this hostile rhetoric from the Trump administration and its withdrawal from the UN climate regime – coupled with its support for fossil fuels – doesn’t tell the whole story of what’s happening in the US, according to Lou Leonard, the first dean of the School of Climate, Environment, and Society at Clark University.
At the state, city and community level, as well as in business and higher education, efforts are resolutely continuing to reduce planet-heating emissions, boost clean energy and adapt to climate shocks, Leonard, an environmental lawyer, told Climate Home News in an interview from Massachusetts.
Thanks to impetus from coalitions such as America Is All In – whose predecessor group he helped launch – the US can still make significant progress towards its 2035 goals to cut emissions, research shows. Leonard, who worked as senior vice president for climate and energy at the World Wildlife Fund for over a decade, explains how US climate action and the Paris Agreement can survive Trump’s wrecking ball.
Q: Has the effect of the Trump administration’s efforts to undermine global climate action and the UN climate process been worse than you expected?
A: A thing that is striking to me, looking at the decade of the Paris Agreement… is that over the course of that decade, the United States had a hostile sort of leadership in Washington, and the agreement has endured.
And it has endured despite the United States, not because of the United States – at least from a federal standpoint. The US was really important in the formation stage but has not been as vital to the endurance of the agreement.
Q: Is it not fair to say though that the current US abandonment of the UN climate process could reduce the impact and influence of the Paris Agreement?
A: The nature of an international cooperative framework means that the aggregate ambition is as strong as the countries that make up it, right? I’m not saying that, in the dream scenario where every country was in a really aggressively positive place that we would not get more out of the international framework. There’s no question that that’s true.
I think it’s just when we’re thinking about the singular role of one country – even the United States – there’s much more in play here than that theory of how things were going to work; the centrality of the United States to all this, especially at the Washington level. I think that turned out to be wrong – at least in the longest sweep of the progress that we’ve made.
Fossil Free Zones can be on-ramps to the clean energy transition
I think the reason why what’s happening in Washington didn’t have as great an impact as it might have in the rest of the world is because the story of what’s happening in the United States is not limited to what’s happening in Washington.
And that’s the second part – which is the things that sometimes frustrate people about the American political system – the sharing of power and the federal system, and all of those things which were intentionally built into the US system.
In these moments, that structure has helped create a reality… and then the rest of the world can see for itself that there’s all these efforts through America Is All In and in other places to bring those actors and that leadership and analysis of the impact of that effort to the rest of the world. I think that that has been an important part of the story of why the Paris Agreement has endured.


Q: What have some of the most important of those subnational efforts been in your view?
A: California’s the most obvious example, because it’s the world’s sixth largest economy and it’s certainly one of the most aggressive states moving forward on climate action. But it’s more than that: if you look at the America Is All In analysis that was released at COP30 in Belém, it shows a roadmap to maintain US trajectories, as a way to keep things from really collapsing when you have these changes in federal leadership.
There’s a parallel there to what’s happening globally – this is a distributed effort. We need all of society, all over the world, to be moving in this direction in order to reach our most ambitious goals.
And I think the fact that the US has over half of the economy, at least, really leaning in this direction really helps. And then if you just look at the energy transition in the US, we have begun to reach this tipping point where the role of the markets and the role of politics are shifting to some degree.
We really needed the policy incentives, and a lot of that [earlier] signal coming from Washington and then the states to get us to a point where renewable energy penetration was significant enough to begin to have momentum on its own, and I think we’re starting to see that. In just the last two years, over 90% of the new generation capacity in the United States has been renewables.
Q: Where do you see real momentum on US climate action continuing or gathering pace despite what Washington is up to?
A: What I really think is going to take us to another level than just relying on state governments… is the catalysing of more of a collaborative “all of society” approach here.
That’s what led me to higher education. I felt like there was an understanding and an alignment within higher education of the importance of these topics – and then the bench within higher education is filled with some of the top experts in the world on climate who were already leading as it related to climate science and talking about the problem. But if we could take that capacity and bring it into more direct relationship with businesses, municipalities and states, then that has the potential to unlock more of the impact of those actors together … that’s the reason I made the move.
The thing that drew me to [Clark] was you had a small university with really a national research capacity. And in Massachusetts, you have the only state in the country that has a chief climate officer that reports to the governor. You’ve got policy that’s been put in place related to green banks and zoning rules related to decarbonisation of buildings. And a state-based climate law that’s aligned with the Paris Agreement goals and has decarbonisation or net zero emissions by mid-century. You’ve got that policy piece in place, and then it’s how can you begin to catalyse some more of the collaboration that’s going be necessary to actually meet those goals? I think that’s really exciting.
Iran war could boost fossil fuel phase-out push, says Colombian minister
Another place where we’re seeing these ingredients come together is Pennsylvania. Just a month ago, the state of Pennsylvania created a new programme called Prepare PA, which is both about preparing for climate impacts and reaching goals related to the energy transition and the like. And they’re putting Penn State University at the centre of trying to help them implement a plan that involves businesses and municipalities. I think you’re seeing more and more of this kind of experimentation.
… This was always going to be an all-of-society effort, and the more we can see that, and the more we can make it real – how we all have roles to play at the local level, at the state level, in the private sector, in universities, in civil society, the more we have the opportunity to avoid this sense of powerlessness [about climate change] that can lead us to nihilism.

Ugandan farmers launch UK court case against East African oil pipeline
Four Ugandan farmers filed a case with London’s High Court on Tuesday, aiming to stop the East African Crude Oil Pipeline (EACOP) from starting to operate by asking the court to apply Uganda’s laws against the project’s UK-registered company.
The controversial 1,443-kilometre (897-mile) pipeline, majority-owned by French energy company TotalEnergies, aims to carry crude from Ugandan fields for export through neighbouring Tanzania. About 80% has been built so far, according to its developers.
The pipeline’s first oil exports are expected as soon as October, according to its developers, and the campaign group Avaaz, which is backing the farmers’ crowdfunded lawsuit, called it “one final chance to stop one of the worst oil pipelines on the planet”.
The claim, filed by London law firm Leigh Day, argues that EACOP Ltd’s role in developing and operating the pipeline breaches Ugandan laws that protect citizens’ right to a clean and healthy environment.
One of the claimants, Racheal Tugume, told a press conference she had been displaced from her land due to the pipeline’s construction, which she said had damaged local rivers, wildlife and ecosystems that communities depend on for their livelihoods just as erratic weather linked to climate change takes an increasing toll.
“I am very happy that there are people in countries like the UK who are listening to us, who are behind us and who have come to support us,” Tugume said, adding that she hoped the case would bring justice to communities affected by the pipeline.
Ugandan law in UK court
While the pipeline is a joint venture led by TotalEnergies, with smaller stakes owned by Ugandan, Tanzanian and Chinese national oil firms, it is operated by EACOP Ltd, a company registered to an office in London’s Canary Wharf financial district.
EACOP Ltd did not respond to a request for comment.
The claim appears to be the first attempt to have Uganda’s climate and environmental protections enforced in a foreign court, partly reflecting concerns over whether cases challenging the multibillion-dollar pipeline would get a fair trial in Uganda.
Ugandans living near new oil pipeline let down by compensation programmes
Concerns about access to a fair hearing are among the issues the court will consider when deciding if it should take on the case, said Matthew Renshaw, partner at Leigh Day.
Renshaw said that precedents including the Nigerian oil pollution case against Shell have shown that claims against British-registered companies for harms overseas can be successfully fought in UK courts.
“We are proud to represent the four brave principled individuals,” Renshaw said.
Constitutional protections
The pipeline project has already been subject to repeated lawsuits in several countries, none of which have succeeded. A climate lawsuit filed in Uganda more than a decade ago by a group of young people has yet to conclude. Another at the East African Court of Justice, brought by campaign groups against Uganda and Tanzania, was rejected on procedural grounds last November.
A separate ongoing lawsuit in TotalEnergies’ home country of France – a refiled version of an earlier failed claim – cannot stop EACOP going ahead, but it does seek damages from TotalEnergies for affected communities.
With the newly launched case, Leigh Day’s legal adviser Marc Willers said the claim draws on specific Ugandan laws in a bid to stop EACOP’s operations.
Uganda may see lower oil revenues than expected as costs rise and demand falls
These include the Ugandan constitution, a 2019 environmental law and the National Climate Change Act 2021, which gives Ugandans the right to bring a case before a court in circumstances where anyone or any entity threatens the country’s ability to mitigate climate change.
Stopping a “carbon bomb”
The pipeline, which will link Uganda’s Lake Albert oil fields to Africa’s east coast in Tanzania, has already displaced thousands of people and cuts through the Lake Victoria basin, one of East Africa’s major freshwater systems and a critical water source for around 40 million people.
According to the BankTrack non-profit, when the pipeline is at peak production, it will carry 216,000 barrels of crude oil per day and release over 33 million tonnes of carbon emissions each year. Over its full lifetime of 25 years, it is estimated to release about 379 million tonnes of greenhouse gas emissions across its value chain including construction, refining and product use.
A May 2026 report from Earth Insight also warns that the pipeline and related infrastructure could affect 158 wetlands in Uganda, 11 rivers, 44 protected areas and seven key biodiversity areas while disrupting about 2,000 square km of protected wildlife habitats.
This is why the primary focus of the UK court case is to stop the operation of the pipeline in its tracks, Leigh Day’s Willers said, calling it a “carbon bomb” that would worsen the world’s climate crisis.
Long wait for first hearing
While the purpose of the case is to stop the pipeline from launching operations, Renshaw said it could take about 12 months before the case gets a first hearing and about 18 months before it goes to trial.
Billions unlocked as Green Climate Fund agrees to spend more and save less
The farmers are, however, seeking an injunction to stop EACOP Ltd from proceeding with operations. In the event that shipments begin, the lawsuit will still seek to stop the pipeline from then on, Renshaw said.
“We will be doing what we can to expedite matters but it is possible that EACOP will have started operating the pipeline before the claim is heard. If that is the case, the claim would intend to halt operations from that point. For example, the pipeline may operate for just one year rather than 30-plus, resulting in far less harm,” he said.

Cited 7 July 2026: ‘Impossible’ heat | Global ocean record | Climate change and the ozone hole
Welcome to Cited, your essential guide to new climate research.
In the news
‘HEAT ALERT’: At least 25 people died as a “heat dome” smothered the eastern half of the US, reported the Guardian, with more than 20 states under “stifling temperatures more than 100F (38C)”. More than 140 million people were under heat alerts, the outlet said, with dead bodies found in “homes with no air conditioning, outside their residences, on the street and in parked cars”. Analysis by World Weather Attribution (WWA) found that the combined heat and humidity would have been “virtually impossible” without human-caused warming, reported the New York Times.
‘MORTALITY WILL RISE FURTHER’: Meanwhile, extreme heat continued to hit Europe, with Le Monde reporting on temperatures of 40C in France, Portugal and Spain again this past weekend, alongside “devastating” wildfires. Public Health France doubled its preliminary estimate of the “excess deaths” from the extreme heat in late June, from 1,000 to more than 2,000, according to the Guardian. The higher figure was still “probably an underestimate”, the agency said. Analysis published by Carbon Brief put the figure at 2,700 heat-related deaths. A WWA attribution study, covered by Carbon Brief, found that Europe’s June heatwave would have been “virtually impossible” even 50 years ago.
‘BOOST TO GLOBAL TEMPERATURES’: The UN World Meteorological Organization (WMO) “raised its forecast for the rapid emergence of a strong El Niño in the coming months, warning that the phenomenon is likely to drive global temperatures higher”, reported Reuters. A WMO scientist told the newswire that “El Niño conditions have emerged in the equatorial Pacific and there is a remarkable agreement between forecast models that this will be a strong El Niño”.

On 21 June, global average sea surface temperature (SST) reached a record high for the day of the year, according to the Copernicus Climate Change Service (C3S). Daily SST for the global ocean, excluding polar regions, reached 20.86C on 21 June, exceeding the 20.83C reached on the same day in both 2023 and 2024, the C3S said. Global SST has remained at record levels for every day since. The conditions “could indicate the beginning of a new phase, leading, once more, to uncharted territory”, said C3S director Carlo Buontempo.
56 hours and 30 hours
The amount of time that the average lifespan of tropical cyclones in the north-east and north-west Pacific has shortened, respectively, over 1982-2024, according to a study in npj Climate and Atmospheric Science. This shorter lifespan “compresses the time available for weather forecasting and disaster preparedness”, the authors said.
Spotlight
The ozone hole and climate change
As a new “thought experiment” asks whether the hole in the ozone layer could, theoretically, have been identified decades before it was discovered, Carbon Brief explores the interactions between climate change and the ozone hole.
It is now more than 40 years since the discovery of the hole in the ozone layer over Antarctica, detailed in the journal Nature in 1985.
A study more than a decade earlier had predicted that chlorine-based substances – such as chlorofluorocarbons (CFCs) – could lead to the destruction of ozone in the stratosphere.
So, in theory, how early could the ozone hole have been detected?
New research, published in the Proceedings of the National Academy of Sciences, explored this very question.
Study co-author Prof Susan Solomon from the Massachusetts Institute of Technology is a leading atmospheric scientist. In the late 1980s, Solomon and colleagues identified the mechanism behind how CFCs were causing ozone depletion.
The new study is a “thought experiment”, Solomon told Carbon Brief, asking when scientists could have discovered the ozone hole had they had access to modern satellite observations.
“We found that depletion could have been detected as early as 1957 in the tropical upper stratosphere, where natural variability is especially small,” explained Solomon.
This would have been before the use of CFCs became widespread, Solomon added. Instead, early ozone depletion was caused by carbon tetrachloride, a chemical used as a cleaning agent, as well as in fire extinguishers and for producing refrigerants.
For many decades, the ozone hole and global warming have often been confused by the public and the media, Solomon explained:
“It’s common to imagine that because ozone is so important at shielding us from the UV [ultraviolet] light that causes skin cancer, then having less ozone must mean the Earth would warm up.”
For example, in a 1995 editorial, the Los Angeles Times congratulated the Nobel prize-winning chemists who identified the threat of CFCs to the ozone layer. The newspaper noted that these processes “threaten calamitous global warming by damaging the Earth’s protective layer of ozone”.
However, said Solomon, “the Earth is warmed much more by visible light – UV doesn’t really contribute, so ozone depletion doesn’t cause significant warming”.
Regional impacts
The depletion of ozone actually has a very small cooling effect at the Earth’s surface. But this is more than outweighed by the warming impact of CFCs and other ozone-depleting substances.
This warming impact means that efforts to reverse ozone depletion have had a beneficial impact on the climate.
The Montreal Protocol, a 1987 international agreement to phase out CFCs, “has played – and is playing – a very substantial role in safeguarding climate too”, said Solomon:
“It turns out that the CFCs and their replacement gases HCFCs [hydrochlorofluorocarbons] are strong greenhouse gases, so phasing out their production has not only avoided a lot of ozone depletion that would otherwise have occurred, it also had a big influence on global warming.”
HCFCs were considered as “transitional substitutes” for CFCs – they still damaged ozone, but to a lesser extent – until ozone-safe alternatives were commercially available.
Hydrofluorocarbons (HFCs), which are not ozone depleting, began to be used widely in the 1990s. However, HFCs are also potent greenhouse gases. HFCs and similar replacements are now being phased out under the 2016 Kigali Amendment to the Montreal Protocol.
While the ozone hole itself has only a very small impact on global temperatures, it does have a clear impact on the regional climate over Antarctica.
Prof David Thompson from Colorado State University, working with colleagues including Solomon, has published research demonstrating that “changes in southern-hemisphere winds linked to the stratospheric ozone losses extend all the way down to the ground in some seasons”, explained Solomon.
This has “reduc[ed] warming that would have occurred in interior Antarctica and enhanc[ed] warming in the Antarctic Peninsula region”, she said.
The knock-on impacts include “wind changes [that] actually extend beyond Antarctica to the mid-latitudes of the southern hemisphere, where they even affect rainfall”, she added.

Guest post: France’s June heatwave caused more than 2,700 heat-related deaths
In June 2026, a record-breaking heatwave swept across Europe, with France among the first and hardest hit countries.
In a new analysis, we estimate that the extreme conditions caused more than 2,700 heat-related deaths in France.
We also show how France’s extreme temperatures in June exceeded projections from climate models.
Our findings illustrate the human toll of extreme weather as the world warms.
We also highlight the challenges in projecting the magnitude of future heatwaves and their impacts on people.
Outpacing projections
For most of this century, Europe has seen summer heat extremes that outpace projections from climate models.
Several different factors likely explain this trend, including reductions in planet-cooling aerosols as nations have cleaned up their air pollution, as well as changes in atmospheric circulation patterns, which models struggle to represent.
In June 2026, daily high temperatures averaged across France reached 36.9C, shattering the previous June record set in 2022 by 2.4C.
[For more on the impacts and coverage of Europe’s June heatwave, see Carbon Brief’s explainer.]
The rise in observed temperatures in France has outpaced projections made by climate models, with June maximum temperatures more in line with what was expected for the 2070s.
This is illustrated in the figure below, which shows how France’s average maximum daily high temperature for June recorded in 2026 (black line) compares to climate model projections (blue and orange lines).

Counting the death toll of climate change
The downstream impacts of these extreme temperatures are lethal.
Scientists are able to estimate the death toll of high temperatures in many locations, depending on the availability of mortality and climate data.
There are several ways to do this.
One option is to examine death certificates to see which deaths have been directly recorded by physicians as related to heat. However, there is strong evidence that this method significantly undercounts heat-related deaths, as most death certificates do not consider environmental factors such as heat when diagnosing the cause of death.
Alternatively, it is possible to calculate the rate of total (“all-cause”) mortality in a given time period relative to previous time periods – for example, by comparing the total number of deaths in June 2026 compared to the average of previous Junes. This “excess deaths” figure can be used as an estimate of the deaths from a heat wave.
Using this approach, Public Health France attributed around 2,000 deaths in France to the extreme heat in the week of 22-28 June.
Finally, scientists can use long-term data on overall mortality and correlate changes in mortality with changes in temperature to understand the statistical relationship between the two.
Research published in Proceedings of the National Academy of Sciences in 2025 that used this third approach found that mortality rates in France increase rapidly in cold or hot conditions as daily maximum temperatures depart further from approximately 20C.
This pattern of a U-shaped response of mortality to temperature – shown in the figure below – is very consistent across time periods and regions around the world.

To calculate the death toll of the June 2026 heatwave in France, we compared observed temperatures over 12-29 June to their baseline average over 1980-2025.
The difference between these two temperatures helps us understand how many more people died than they would have in the absence of such extreme conditions.
Over 12-29 June, we found that France has experienced around 2,700 heat-related deaths above the average baseline. Day-to-day heat-related mortality rates rose from less than 100 to almost 300 on the hottest days of 24 and 25 June.
This is shown in the graph below, which illustrates the cumulative total heat-related deaths seen in France over the two-and-a-half week period. The inset shows how heat-related deaths fluctuated on a day-to-day basis during this time.

Recent analysis by World Weather Attribution has already shown that human-caused climate change increased the frequency and intensity of the June heat wave across Europe.
Meanwhile, previous research has shown there is substantial evidence that heat-related mortality in Europe has already been elevated by greenhouse gas emissions.
As a result, we can be confident that at least some of the more than 2,700 deaths already seen in France are directly due to the burning of fossil fuels.
Calculating climate risk
In April, the UN-led body responsible for coordinating the work of climate modelling centres – the Coupled Modelling Intercomparison Project (CMIP) – unveiled a set of seven new emissions scenarios.
These are designed to replace the previous scenarios that have been used by scientists to understand how the climate might change in the future. They will feed into the upcoming seven assessment report (AR7) of the Intergovernmental Panel on Climate Change (IPCC).
The range of future emissions in the new CMIP scenarios is smaller, with scenarios of very high or very low emissions no longer on the table.
The retirement of the very-high emissions scenario – known as “RCP8.5” – led to certain commentators in the media and in politics, including US president Donald Trump, arguing that the risks of climate change had been “overstated”.
[For more on false and misleading claims around the new emissions scenarios, see Carbon Brief’s factcheck.]
Our analysis of June’s heat-related deaths in France suggests that, even if the most severe emissions pathways are no longer needed, climate impacts are taking a heavy toll on society.
Moreover, the temperatures seen in France show that climate models continue to underpredict the magnitude of heatwaves for a particular level of global warming.
This is because greenhouse gas emissions are only a first step in estimating the impacts of climate change.
The second step is converting emissions to changes in the climate at both the global and local levels – or hazards. This includes heatwaves, flash floods and droughts.
The third step is to determine how changes in the hazards will affect local populations. This can be determined by calculating people’s exposure and vulnerability to hazards.
Substantial uncertainty persists at every stage of this sequence.
For example, scientists do not know exactly how the global climate will react to ever-rising greenhouse gas emissions – nor the extent to which global temperature increases will drive local climate hazards. We also do not know how climate change at a local level impacts human health outcomes.
Managing the future of heat risk
Almost all heat-related deaths are preventable.
Adaptation options, such as air conditioning, heat action plans and social support for isolated people, will be crucial as the climate moves away from the typical conditions that people are used to.
Our previous research showed that France made a lot of progress reducing heat-related mortality after the deadly 2003 summer heatwave by taking many of these actions.
Adaptation can reduce deaths, but it cannot eliminate the risk created by continued warming.
Without a move away from fossil fuels, future heatwaves will keep testing the limits of public health systems and more people will die.
