Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Asian extreme weather
SWELTERING: An intense heatwave is sweeping across south and eastern Asia. The Dhaka Tribune said temperatures in Bangladesh have surpassed 40C in many regions and the Daily Star reported that the country recorded at least 23 days “heatwave days” in April. Agence France-Presse reported that Thailand’s capital, Bangkok, reached 40.1C on Wednesday. The Bangkok Post added that temperatures could reach 43C in northern Thailand next week. (See Carbon Brief’s recent on-the-ground reporting on the impacts of climate change on human migration in Thailand.) Schools across the Philippines, Bangladesh and India have been forced to close due to the heat, according to BBC News.
ELECTION HEAT: In India, the heatwave coincides with the country’s six-week general election, in which nearly one billion people are eligible to vote, the New York Times reported. India’s election authorities have set up a taskforce “to review the impact of heatwave[s]” on the election after a significant decrease in voter turnout, the Indian Express said. India’s Economic Times added that temperatures in the country will peak on 27-28 April.
FLOODING: More than 110,000 people have been evacuated from China’s Guangdong province after record-breaking rainfall caused widespread flooding, state news agency Xinhua reported. China Daily said that southern China has experienced more than double the typical rainfall for April. The flooding has caused economic losses exceeding 140m yuan ($19.8m), according to the People’s Daily Online. Meanwhile, the Financial Times reported that the World Meteorological Organization has published a report warning that climate change “is causing major repercussions across Asia”.
Legal action
HISTORIC ENQUIRY: The Inter-American Court on Human Rights in Barbados is hearing the first part of a “historic” inquiry this week, the Guardian said. The New Humanitarian reported that Colombia and Chile are “asking the hearing to define states’ legal responsibility to combat climate change and prevent it from violating people’s human rights”. It added that the court will hear from Julian Medina, a Colombian fisherman, among others.
HEALTH FAILURE: A group of South Koreans is suing their government for failing to protect 200 people, including young environmental activists and children, by not tackling climate change, Reuters reported. “The proceeding is Asia’s first such climate-related litigation,” the newswire added. Meanwhile, BBC News reported that an Iraqi man is taking legal action against BP, alleging that his late-son’s leukaemia was caused by the oil company’s flaring practices.
SUSPENDED: Meanwhile in the UK, Dr Sarah Benn, a retired GP in Birmingham, has had her medical licence suspended for five months following her involvement with Just Stop Oil protests and risks being stuck off permanently, the Guardian reported. According to the Times, the 57-year-old was previously jailed for 31 days after taking part in three climate protests at an oil terminal in Kingsbury in 2022. There has been backlash to the ruling, which the British Medical Association called “very concerning”, the paper added.
Around the world
- EARTH DAY: US president Joe Biden marked “Earth Day” on Monday by announcing $7bn of investment into solar energy projects, the New York Times reported.
- CONTROVERSIAL TREATY: EU lawmakers have voted “overwhelmingly” for the bloc to leave the international energy charter treaty, according to the Financial Times. The paper called the ruling a “victory for climate advocates”, adding that many think the treaty protects fossil fuels.
- UNHELPFUL SLOGAN: Chris Stark, the outgoing chief executive of the UK’s Climate Change Committee, told the Guardian that “net-zero” has become an “unhelpful” slogan, which is often “associated with the campaigns against it”.
- MEXICAN DROUGHT: Nearly 80% of Mexico’s territory is now under drought conditions, Excélsior reported. EuroNews added that drought, combined with a surge in water demand to grow crops such as avocados, is causing rivers and lakes to dry up in the “once green and lush” state of Michoacan.
- DEADLY FLOODS: Countries across east Africa have been “lashed by relentless downpours in recent weeks”, Al Jazeera reported. The outlet warned that “deadly floods” are sweeping through Kenya’s capital Nairobi.
- CLIMATE RISK: The World Bank is advising South Africa’s national treasury on climate risk strategies, such as taking out climate insurance or setting up contingency funds, following floods which have caused billions of dollars of damage in recent years, reported Bloomberg.
2.4 billion
The number of workers globally expected to face “excessive heat conditions” at some point during their careers, according to an International Labor Organization report covered in the Associated Press.
Latest climate research
- A study in Nature Climate Change found that meteorological definitions for extreme weather events do not fully capture the negative impacts experienced by women in informal settlements.
- The area of land in east Africa affected by combined heatwaves and wildfires could increase by 940% by the end of the century, according to new research in Earth System Dynamics.
- New analysis by the World Weather Attribution service found that the heavy rainfall that hit Oman and the United Arab Emirates recently was 10-40% heavier than it would have been in an El Niño year without climate change.

Captured

The past 10 months have all set new all-time monthly global temperature records, with April 2024 on track to extend this streak to 11, wrote Dr Zeke Hausfather in his latest quarterly “state of the climate” report for Carbon Brief. The graph shows monthly temperatures over 1940-2024, plotted with respect to a 1850-1900 baseline. Based on the year so far and the current El Niño forecast, Carbon Brief estimates that global temperatures in 2024 are likely to average out at around 1.5C above pre-industrial levels.
Spotlight
Climate science in the courtroom

Last week, a group of 2,000 Swiss women won a landmark case in the European Court of Human Rights. The women, mostly in their 70s, said that their age and gender made them particularly vulnerable to heatwaves linked to climate change. The court ruled that Switzerland’s efforts to meet its emissions targets had been “woefully inadequate”.
At the annual European Geosciences Union (EGU) general assembly in Vienna, Carbon Brief interviews Prof Wim Thiery – a scientist who was involved in multiple conference sessions on climate change and litigation. This interview was edited for length.
Carbon Brief: What types of climate science are used in litigation?
Prof Wim Thiery: Just like how there’s a range of different subfields in climate science, we have a range of different climate cases. For example, there’s attribution science which supports reparation cases. We are seeing carbon budget research and fair-share emission pathways research supporting cases on climate policies. And we’re also seeing future climate impact projections supporting cases that are started by young people around the world.
CB: What science was used in the recent European case?
WT: Impact attribution research played a key role. Recent studies by [Oxford University researcher] Dr Rupert Stewart-Smith and [Swiss epidemiologist] Dr Anna Vicedo-Cabrera, for example, showed that all women in Switzerland are disproportionately at risk of heat-related mortality in Switzerland. So, these are recent scientific publications that were directly mentioned in court and that played an influence on the final court ruling.
CB: Do you think the methods used in attribution science are changing to better support litigation?
WT: We are seeing an evolution in attribution science, whereby we move from the traditional science of long-term trends in climate variables, to the operational ability to – in almost real time – establish the link of climate change with the occurrence of individual extreme events. And we’re seeing a new evolution whereby communities are increasingly looking at impact-relevant variables. Think about inundated areas, lake levels, heatwave mortalities. These are the new target variables of attribution science. This is a new frontier and we are seeing that those studies are directly usable in court cases.
CB: Do you ever worry about your research, or that of your colleagues, becoming ‘too political’?
WT: We are used to, in climate science, working with policymakers and with society. Our research is of direct societal relevance and this is just a new example. For me, this is just another example of working with stakeholders – lawyers are a new group of stakeholders for our community.
There is a very direct and tangible impact when you see that an attribution study or a particular scientific publication is used in a court case and has a direct effect on its evolution. It’s very tangible, the outcomes, and I think that’s something which motivates climate scientists in engaging in this community.

UN chief urges countries to adopt fossil fuel transition plans with timelines
The head of the United Nations has called on all countries to deliver plans for phasing out their production and consumption of fossil fuels, as rising oil prices and climate shocks threaten energy and human security.
In his farewell speech to the UN General Assembly (UNGA) in New York on Tuesday, outgoing UN Secretary-General António Guterres for the first time urged “every government to adopt a national plan to transition away from fossil fuels” aligned with limiting warming to 1.5C. The plans, he said, should include “clear timelines and protection for affected workers and communities”.
“We know fossil fuel interests won’t step aside on their own. For decades, Big Oil has treated the atmosphere as an open sewer – and cashed in on the consequences,” Guterres told diplomats in his speech opening the leaders’ segment of the assembly, also calling out the industry’s windfall profits after Russia’s invasion of Ukraine.
At last year’s COP30 climate summit in Belém, a group of about 80 governments led a failed push to develop a global roadmap to transition away from fossil fuels. Brazil instead proposed to draft a voluntary report that will be presented this year ahead of COP31 after countries and organisations submitted their views to the process.
Governments first agreed to transition away from fossil fuels in energy systems at COP28 in Dubai in 2023, but have since failed to agree at UN climate talks on how to move forward with that commitment, as efforts to do so have been effectively blocked by large fossil fuel-producing countries.
France, Netherlands issue plans
A few countries have moved forward with their own transition plans. France launched the first one at an international conference on the issue in April and the Netherlands followed suit this month. Not being major fossil fuel producers, both European nations aim to end their coal, oil and gas consumption by 2050, although the Dutch plan was criticised for not setting specific phase-out dates for the dirty fuels.
Adão Soares Barbosa, climate ambassador from Timor-Leste and chair of the Least Developed Countries (LDC) group in the UN climate negotiations, told a press briefing on Tuesday that last year’s discussions on shifting away from fossil fuels need to continue at COP31, adding that developed countries should lead the way with transition plans and curb their use of fossil fuels.
“We are expecting that we can make a request to major-emitting countries to limit emissions from this sector,” he said. “For LDCs, we’ll also try to reduce fossil fuel use, but it will depend on national circumstances.”
Samoa’s lead negotiator Anna Rasmussen said small island states have outlined their energy transition plans in their nationally determined contributions (NDCs) – countries’ plans for meeting the Paris Agreement goals – but added “we’re still waiting” for climate finance to help implement those plans.
Despite the global push to clean up the energy mix, countries leading climate talks are themselves also expanding fossil fuel production. COP31 co-presidents Australia and Türkiye have both recently given the green light to mine and drill more coal, oil and gas, and still depend on fossil fuels for 60% and 56% of their electricity production respectively.
Fossil fuel expansion threatens COP31 hosts’ credibility, experts warn
COP30 host nation Brazil has also persisted with its plans to explore potential new oil reserves near the mouth of the Amazon River – a region known as the Equatorial Margin.
These are moving ahead despite President Luiz Inácio Lula da Silva announcing last year at the Belém climate summit that the country would develop its own fossil fuel phase-out plan. This is still under development with little information about its progress and may be hampered by elections next month.
“We have achieved our self sufficiency in oil and will continue to explore the potential of new reserves, such as those in the Equatorial Margin,” Lula said in his speech to the UNGA on Tuesday. “But we will not abandon the environmental agenda,” he insisted. “We will move forward with the roadmap for the decarbonisation of the Brazilian economy.”
Transition far cheaper than status quo
Speaking at the main Climate Week NYC venue, Mads Christensen, executive director of Greenpeace International, said given the fast-shifting cost dynamics for both fossil fuels and renewables, countries should revise their existing energy plans because they are now out of date.
Gas power generation now costs around 150 euros per megawatt compared with around 50 euros for solar with battery storage – making the latter two-thirds cheaper.
“If these plans were updated, I think we would have a much faster transition because it simply makes good financial sense,” he said.


Tzeporah Berman, founder and chair of the Fossil Fuel Treaty Initiative, told Climate Home News that the Santa Marta process for transitioning away from fossil fuels (TAFF), launched at April’s conference, could help countries discuss, design and develop their national roadmaps, as well as mobilise the international cooperation required to actually deliver them.
“Many countries want not only national roadmaps but a global roadmap off the highway to hell,” she added. “A global plan is necessary to ensure the rules aren’t rigged against those who want to do the right thing and so all countries can make credible commitments.”
The second TAFF conference will be held in the Pacific island nation of Tuvalu next spring, co-chaired by Ireland. In New York, Tuvalu’s climate minister Maina Vakafua Talia called for stepped-up efforts to tackle the fossil fuel use that is threatening his country’s “demise” by driving global warming.
“The world is running out of time, and so I ask every government to come to… Tuvalu with solutions – real solutions, not false solutions – for us to ensure that we have a pathway and a way forward,” he urged.

COP31 electrification pledge leaves out clean power commitment
COP31’s flagship initiative to accelerate the electrification of the world’s economy has been criticised for failing to include a commitment to produce the power from clean energy.
Governments that sign the voluntary pledge at this year’s UN climate summit will commit to increasing electricity’s share of total energy consumption to 35% globally by 2035 in line “with pathways consistent with keeping 1.5C alive”, the text unveiled by the Turkish presidency on Tuesday says.
While the document says that the electrification goal is “complementary to efforts to expand renewable energy and improve energy efficiency”, governments are not explicitly asked to commit to producing the extra power with clean sources and driving down greenhouse gas emissions.
The text instead says the “use of clean electricity” will vary according to national circumstances. Fossil fuels are not mentioned by name, although the pledge cites the COP28 Global Stocktake decision, which called for “transitioning away from fossil fuels” in energy systems.
COP31 president Murat Kurum said earlier this month that the push to make electrification more “widespread” – through measures like the rollout of electric vehicles and heat pumps – will “automatically” lead to a reduction in the use of fossil fuels.
But many campaigners disagree, criticising the proposed pledge for failing to give an explicit signal on the fossil fuel transition.
Lack of clarity on energy sources
“Let’s not let electrification become the Trojan horse of our times, used to hide new fossil fuel consumption rather than promote renewable energy,” Claire Smith from civil society umbrella group Beyond Fossil Fuels said in reaction to the pledge’s publication.
She added that the commitment will only help address the climate crisis if electrification is powered by a flexible energy system where solar and wind are complemented by enhanced grids and storage.
The pledge’s text says that the electricity goal should be supported by “diverse and sustainable energy sources”, but it stops short of explaining what these sources are.
Alden Meyer, an international climate policy expert and senior associate at think-tank E3G, said the details of the pledge matter to how effective it will be in helping bring planet-heating emissions down.
“It has to be clean, and we haven’t got enough clarity on a guarantee that it will be a decarbonisation move,” he told Climate Home News.
China’s industrial engine starts to break its fossil fuel habit
According to an annual electricity review from energy think-tank Ember, in 2025 renewables edged ahead of coal power for the first time in 100 years. Continued growth in solar and wind pushed the share of renewables above a third of global electricity generation to just under 34%, compared with coal at 33%, it said.
Janet Milongo, energy Transition lead at CAN International, said success cannot be measured simply by how much of the world’s final energy consumption becomes electric.
“We must ask what generates that electricity, who has access to it, who owns the infrastructure, and whether it is helping communities transition away from fossil fuels,” she added.
Electrification alone can’t meet climate goals
Analysis published by the IEA on Tuesday, alongside the pledge, found that it would already be cost-effective to raise electricity’s share of global energy use from 23% today to around 33% with existing technologies, putting the COP31 goal “within striking distance”. Based on current policies, however, the share reaches only about 30% by 2035.
Hitting the 35% target would cut fossil fuel importers’ import bills by around $400 billion a year by 2035, the IEA said. At the higher prices caused by the conflict in the Middle East, that saving rises to more than $500 billion.
Speaking at New York Climate Week on Tuesday, IEA executive director Fatih Birol said the agency’s figures show that in 2026, about 80% of all new power plants built will run on renewables, with a few percentage points coming from nuclear power and the rest from fossils fuels. “So therefore, electrification itself will lead reduction of the [greenhouse gas] emissions,” he added.


However, the IEA warned in its new report that electrification “by itself is not enough” to meet the world’s climate targets. It noted that, if “low-emission” sources of power continue to simply grow in line with current policy scenarios, that would be only just enough to cover the extra demand from electrification, driving a modest decline in emissions.
Matt Webb, associate director of global clean power diplomacy at E3G, said the pledge is a “welcome signal of leadership” and can help COP31 be a “critical moment” for countries to double down on the energy commitments made at COP28.
But to secure the full benefits of electrification, he added, it is essential that we “urgently clean up” by speeding up the rollout of renewables and developing credible national plans to transition away from fossil fuels.

As loss and damage fund stalls, Nepal crowdfunds flood relief
People around the world have donated almost $90 million to a government-led campaign to help Nepal recover from its recent devastating Himalayan flood, according to a Nepali climate negotiator, even as the UN chief slammed the tiny amount of money in a new fund to deal with such disasters.
Individuals and companies from Nepal and abroad have chipped in from $5 to “many millions” of dollars to the Prime Minister’s Disaster Relief Fund, Manjeet Dhakal, an advisor to the poorest countries at UN climate talks, told an event on Monday focused on early warning systems.
The prompt and substantial response from the public contrasts with the slower, more limited support that is potentially on offer from the UN’s new Fund for Responding to Loss and Damage (FRLD), set up by governments to compensate developing countries for climate disasters.
Comment: Human security relies on adapting to the world’s new climate reality
Over three weeks have passed since Nepal’s finance and environment ministers asked the FRLD board to take an urgent decision to allocate funding to help Nepal protect people and restore essential services in the wake of the disaster, which caused around 1,450 deaths and left more than 5,000 people missing.
“Time is of the essence,” the ministers wrote in an appeal to the FRLD on August 31, which was swiftly followed by a letter from a group of developing-country board members urging the FRLD board’s co-chairs to organise an extraordinary meeting to come up with a response.
Loss and damage fund hesitates
Yet, despite informal online meetings, the co-chairs have yet to convene a meeting with the power to allocate funds. The board’s next scheduled meeting begins on December 15.
Dhakal said on Monday that the request has “received some positive response, but still there is some discussion ongoing about how to respond to that”.
“If they can’t respond in a timely manner, then is [the fund] fit for purpose in terms of disasters that the world would be facing in the coming years? The scale and intensity of these disasters is increasing,” he said.
With just $820 million pledged to it by rich countries and not all of that yet delivered, the FRLD has earmarked just $350 million to spend in its initial phase and without further contributions could run out of money next year.
Because of these limited funds, and a huge number of requests for funding totalling nearly $3 billion, the FRLD has said it will only give out a maximum of $20 million to each project for now. It has yet to approve funding for any projects.
Dhakal recently told The Nation magazine that this amount was just a “symbolic gesture”. Nepal’s government has estimated the costs of recovery and reconstruction at $4.8 billion, with homes, roads, bridges, hospitals and hydropower stations in the affected area needing to be repaired and rebuilt.
“Ridiculously small” funding
In a speech to the UN General Assembly on Tuesday, the body’s outgoing Secretary-General António Guterres criticised the “ridiculously small” level of funds made available by wealthy governments to the FRLD. Developed countries should “make the loss and damage fund work at scale”, he said.

The Portuguese diplomat told world leaders that when he travelled to Nepal three years ago, he had “sounded the alarm on accelerating glacier melt, warning that the rooftops of the world are caving in”.
“Some dismissed it all as overstating dangers, but as tragic events have shown, impacts are arriving sooner, hitting harder, and spreading further than many anticipated,” he said.
A recent study by scientists with the World Weather Attribution group found that climate change contributed to the rock-ice avalanche which sparked a huge flash flood along a river valley on the Nepal-Tibet border.
Speaking at a separate event in New York on Monday, leading climate scientist Johan Rockström highlighted those findings on the role of global warming in the Himalayan disaster.
“This will be potentially the first poster-child case of a loss and damage invoice, because here we have a proven case of a catastrophe which would not have occurred if it hadn’t been for human-caused climate change,” he said.
