Key developments
‘Tricks’ and ‘cover-ups’
LIVESTOCK EMISSIONS: Climate scientists speaking to the Financial Times accused the governments of New Zealand and Ireland of using an “accounting trick” to “cover up” methane emissions from their livestock sectors. An open letter from 26 climate scientists and covered by the newspaper said that New Zealand’s “proposed new methane targets risk setting a dangerous precedent”. The title added that scientists have separately raised concerns about Ireland’s approach.
POTENTIAL PROBLEMS: The controversy hinges on a way for measuring the impact of methane emissions on climate change, called “global warming potential star” (GWP*), the FT said. This method “estimates [methane’s] contribution to warming based on how emissions are changing relative to a baseline”. By contrast, the “long-established approach” used by most countries “compares the total warming impact of a given mass of methane to the same mass of [carbon dioxide] over a 100-year period”, the newspaper said.
‘MISAPPLICATION’: The scientists told the FT that some governments are “misapplying” GWP* to justify setting “no additional warming” targets, which allow methane emissions to remain flat rather than decline. The governments of Ireland and New Zealand did not respond to the newspaper’s requests for comment. But the newspaper added that “proponents” of the GWP* typically argue that it “better reflects methane’s short-lived nature in the atmosphere compared to the long-lasting effects of CO2”. One of the scientists behind the letter explained more of his thoughts in a LinkedIn post. A scientist not involved in the letter also posted a response.
SOMETHING FISHY: Elsewhere, an investigation by DeSmog and the Guardian has alleged that several UK supermarkets have sold seabass linked to “devastating overfishing” in Senegal. The two publications said that the retailers are accused of selling fish from Turkish farms that import large quantities of “fishmeal” – ground up fish used as feed – sourced from the African nation. Overfishing for fishmeal in Senegal is linked to “unemployment” and “food insecurity”, according to the Guardian. Responding to the claims, several of the supermarkets said they do not currently source from the implicated farms, but declined to say whether they had in the past.
Wild weather worldwide
EARLY MONSOON MAYHEM: An “unprecedented” early monsoon caught India’s farmers off guard, with “massive crop losses in states such as Tamil Nadu, Maharashtra, Telangana and Gujarat”, IndiaSpend reported. Climate scientists attributed the pre-monsoon thunderstorms to “unusual sea surface temperature patterns in the Pacific since 2023” and a higher frequency of “western disturbances” – extratropical storms originating over the Mediterranean. In the past week, north-eastern India has been battered by flash floods and landslides, with “at least 32 people killed and tens of thousands displaced”, the Independent reported. The newspaper noted that “studies show the monsoon in south Asia is getting worse due to the climate crisis”.
DELUGE AND DROUGHT: BBC News reported that more than 700 people are believed to be dead after “devastating” floods hit Nigeria, with the farming region of Mokwa witnessing “the worst [floods] in the area for 60 years”. Separately, Reuters reported that China’s south-western Yunnan province was hit by “flash floods and mudslides”, triggered by heavy rainfall. In unconnected reporting, Bloomberg said that China had stepped up cloud seeding to “bolster rainfall across parched wheat-growing areas” in the north, adding that the country had ramped up “weather modification” investments as “climate change heightens food security risks.”
CANADA BURNS: Canada’s prairie provinces continued to reel from “record-breaking” early-season wildfires, the Guardian reported. It pointed out that in Manitoba alone, wildfires have burned “about 200,000 hectares already this year” – three times “the recent full-year average”. Manitoba premier Wab Kinew said that simultaneous fires “in every region” were a “sign of a changing climate that we are going to have to adapt to”. The Guardian added that First Nations peoples in Saskatchewan – one of three recognised Indigenous peoples in Canada – “have been particularly affected, with some entire communities evacuated”.
Spotlight
UK’s former lead negotiator on UN nature talks
In this Spotlight, Carbon Brief speaks to the UK’s former lead UN negotiator about the successes and challenges of international nature talks.
Will Lockhart OBE represented the UK in UN nature negotiations from 2021 until the end of COP16 talks in Rome in February of this year.
In 2022, he helped to negotiate the Kunming-Montreal Global Biodiversity Framework (GBF), a landmark deal which has a headline “mission” to “halt and reverse” nature loss by 2030.
Following his departure from government, he spoke to Carbon Brief about his highs and lows, whether the world is making progress towards meeting its biodiversity goals and the role of UN summits – called COPs – in tackling environmental issues.
Carbon Brief: When you look back at your time heading up biodiversity negotiations, what are your highlights?
Will Lockhart: It’s all still emotionally raw. From a global perspective, the agreement of the GBF was a huge personal highlight. That was a really, really complicated negotiation. The notion that you could have frontpage news that was about an international agreement on nature, that was immensely exciting.
CB: In your view, is it possible to achieve the GBF’s mission to halt and reverse biodiversity loss by 2030?
WL: The trajectory right now would suggest, no, it’s looking incredibly hard to achieve. But, even then, with exactly the right interventions at exactly the right scale, it might still be possible. A fair question might be was it ever possible?…There has always been a contested evidence base about whether it could ever have been achieved.
The important thing is that people spent a lot of time thinking about why we were setting certain kinds of targets…We wanted them to be specific, measurable and achieveable. What does achievable mean? What does ambitious mean? What message are we trying to send? This is politics, this isn’t necessarily science.
If the answer is that it was never possible in the first place, then the question is: ‘Why did the world agree to it?’ And the answer to that is: ‘Because it matters that we try.’
CB: Could there be a better way for countries to address biodiversity loss than the current system?
WL: It’s a very complicated question. A question that everyone has to bear in mind is: ‘What [is the] value [of] the COPs?’ You pour a huge amount of time and resource into a global dialogue, which results in a very, very carefully negotiated outcome. It’s extremely important, in my view, that you have a space where the whole world can come together in a room and agree that it wants to do something. The question is, where does the world locate that process?
I worry that the world is simultaneously asking too much and too little of COPs. It’s asking too much in the sense that there’s so much coverage and intense scrutiny of ‘this person’s arrived’, ‘this comma has moved’…There’s an extraordinary media circus. [There is] extreme expectation on each individual meeting.
And, at the same time, it’s simultaneously asking too little of them. It’s like: ‘Great, this word was in so it was a good COP’ or ‘this word was out so it was a bad COP’. And of course COPs are just one tiny part of this huge global process that needs to happen if we’re going to tackle these problems. I rather worry – and I know that colleagues feel the same – they’re just viewed as ends in themselves.

News and views
RECORD FOREST LOSS: Tropical forest loss hit its highest level in a two-decade record in 2024 – double the level of 2023 – according to satellite data from Global Forest Watch covered by New Scientist. The report authors “attributed the surge in forest loss to the El Niño weather phenomenon and the warming global climate, which made the rainforest a tinderbox”, the magazine said. Climate Home News added that the rate of forest loss was the equivalent of losing 18 football pitches every minute.
RATIFY THIS: The EU ratified the UN “High Seas Treaty” last Wednesday, “joining a global effort to protect the ocean, curb environmental damage, tackle climate change and preserve biodiversity”, Jurist News reported. The EU’s ratification of the landmark treaty was joined by six of its member states: Cyprus, Finland, Hungary, Latvia, Portugal and Slovenia. The EU also pledged €40m as part of a Global Ocean Programme to support African, Caribbean and Pacific countries, according to an EU Commission press release.
THOUSAND CUTS: A “cornerstone” ecological research programme could potentially be culled by the Trump administration, the New York Times reported. Abolishing the Ecosystems Mission Area (EMA) “was an explicit goal of Project 2025, the blueprint for shrinking the federal government”, the story added. However, the budget cut “still needs to be approved by Congress”, with scientists rallying to save the EMA, the paper wrote. On Monday, the Trump administration announced plans to “eliminate federal protections across millions of acres of Alaskan wilderness” that could open the region to drilling and mining, according to another New York Times story.
NET NATURE LOSS?: In the UK, the Guardian reported that the “nature-friendly farming budget is set to be slashed” for “all but a few farms” in an upcoming spending review. Meanwhile, legal analysis of the Labour government’s new planning and infrastructure bill showed that “more than 5,000 of England’s most sensitive, rare and protected natural habitats are at high risk of being destroyed by development”, per another Guardian story. A key concern for green groups, it added, is a “cash for trash” clause that allows developers to “inflict adverse effects on the integrity of a protected site” if they pay into a fund to restore nature elsewhere.
MIRAGE CITY: Reuters reported on Egypt’s plans to build a new desert city, 42km west of Cairo, that could reroute “about 7% of [its] annual Nile River quota” from fertile delta land. According to the story, an estimated 10m cubic metres of Nile water will flow daily to Jirian city to “pass by upscale glass-fronted housing units and eventually” irrigate a 2.28m acre “New Delta” agricultural project. Jirian city will include luxury housing, a free economic zone and even a “yacht marina”, the newswire added, noting that the country is facing “mounting water shortages, power constraints and deepening economic crisis”.
FOREST-FRIENDLY BATTERIES: Electric car batteries made using iron and phosphorus “that pose less of a threat to forests” are “rapidly replacing batteries reliant on cobalt and nickel”, according to an International Energy Agency (IEA) report covered by Climate Home News. From 2020 to 2024, the market share of lithium nickel manganese cobalt batteries has risen from one-tenth to almost half, according to the IEA data. Both cobalt and nickel are “mainly mined in rainforest countries”, such as the Democratic Republic of the Congo and Indonesia, the publication added.

REFORESTED SCHOOLS: Mongabay explored how “urban forests” in schools in Niger are helping to build “climate resilience and education”.
SO LONG, SALGADO: The New Yorker examined the visual legacy of photojournalist Sebastião Salgado, who died last week. Salgado’s Genesis series is celebrated as a “paean to natural landscapes and Indigenous ways of living”.
SECOND ACT: In an Atlantic long-read, writer Emma Marris looked at the debate calling for a law to protect ecosystems along with endangered species in the US.
PROUD, NATURALLY: CBC News reviewed Animal Pride, a new documentary about queer animal behaviour that filmmaker Connel Bradwell described as “nature’s coming-out story”.
New science
- Greater fish biodiversity can help improve nutrition and make fisheries more resilient, according to new research published in Nature Sustainability. The study found that fishing waters with complementary species could provide more than 60% in additional nutrients than a similar-sized catch of the most nutrient-rich species.
- A new study in Nature Climate Change found that “natural climate solutions” in croplands offer only “modest” mitigation benefits if reductions in crop yields are to be avoided. According to the authors, this indicates that “cropland soil will constitute a fraction of food system decarbonisation”.
- New research in Communications Earth and Environment found that global agricultural labour productivity could decrease by 18% by 2100 under a scenario of high heat-stress and labour sensitivity.

Cropped 4 June 2025: ‘Tricks’ and ‘cover-ups’; Wild weather; Former UN nature negotiator interviewed
Months after a collapsed pipe pushed nearly 250 million gallons of raw sewage into the river, residents say the area still smells.
Members of a congressional subcommittee this week questioned utility leaders and state officials about their knowledge of preexisting problems with the sewage line that collapsed on Jan. 19 near the Potomac River.
Congress Grills Officials About the Potomac River Sewage Spill
A formal petition to the U.S. government calls for sanctions on Chinese seafood imports as it highlights China’s loophole-ridden illegal shark fin trade.
For migrant workers trapped onboard Chinese distant water fishing fleets, cutting the fins off sharks as they writhe violently on rusted decks in the Indian Ocean isn’t accidental. It’s an intentional and lucrative act that marks the start of a bloody half-a-billion-dollar offshore supply chain, tacitly supported by Beijing yet covertly concealed from port inspectors globally.
New data on international climate finance for 2023 and 2024 suggests that wealthy countries are highly unlikely to have met their pledge to double funding for adaptation in developing nations to around $40 billion a year by 2025 amid cuts to their overseas aid budgets.
At the COP26 climate summit in Glasgow in 2021, all countries agreed to “urge” developed nations to at least double their funding for adaptation in developing countries from 2019 levels of around $20 billion by 2025. Funding for adaptation has lagged behind money to help reduce emissions and remains the dark spot even as the data showed overall climate finance rose to a record $136.7 billion in 2024.
A United Nations Environment Programme report warned last year that wealthy nations were likely to miss the adaptation finance target and the data released on Thursday by the Organisation for Economic Co-operation and Development (OECD) shows that in 2024 adaptation finance was just under $35 billion.
The OECD, an intergovernmental policy forum for wealthy countries, said the increase between 2022 and 2024 was “modest”, adding that meeting the doubling target would require “strong growth” of close to 20% in 2025.
More cuts likely
The OECD’s figures do not go up to 2025, but several nations announced cuts to climate finance last year. The most notable was the abandonment of US pledges to international climate funds by the new Trump administration but the UK, France, Germany and other wealthy European countries also pared back their contributions.
Joe Thwaites, international finance director at the Natural Resources Defense Council, said developed countries were “not on track” to meet the adaptation funding goal.
Power Shift Africa director Mohamed Adow said adaptation finance is needed to expand flood defences, drought-resistant crops, early warning systems and resilient health services as the world warms, bringing more extreme weather and rising seas. “When that money fails to arrive, people lose homes, harvests and livelihoods – and in the worst cases, their lives,” he warned.
Imane Saidi, a senior researcher at the North Africa-based Imal Initiative, called the $35 billion in adaptation finance in 2024 “a drop in the ocean”, considering that the United Nations estimates the annual adaptation needs of developing countries at between $215 billion and $387 billion.

UK halves Green Climate Fund contribution, as it spends more on security
After promising £1.6 billion to the UN’s flagship climate fund in 2023, the UK government has now said it will only hand over half as much
If confirmed, a failure to meet the goal is likely to further strain relations between developed and developing countries within the UN climate process. A previous pledge to provide $100 billion a year of total climate finance by 2020 was only met two years late, a failure labelled “dismal” by the UAE’s COP28 President Sultan Al Jaber and many other Global South diplomats.
Missing that goal would also raise doubts about donor governments’ commitment to meeting their new post-2025 adaptation finance goal. At COP30 last year, governments agreed to urge developed countries to triple adaptation finance – without defining the baseline – by 2035.
African and other developing countries have pointed to lack of funding as a key flaw in ongoing attempts to set indicators to measure progress on adapting to climate change.
Speaking to climate ministers from around the world in Copenhagen on Wednesday, Turkish COP31 President Murat Kurum stressed the importance of climate finance. “It is easy to say we support global climate action,” he said, “but promises must be kept.”
He said the COP31 Presidency will use the new Global Implementation Accelerator and recommendations in the Baku-to-Belem roadmap, published last year, to scale up climate finance – and will hold donors accountable for their collective finance goals.
He noted that developed countries should this year submit their first reports showing how they will deliver their “fair share” of the new broader finance goal set at COP29 in 2024, to deliver $300 billion a year in climate finance by 2035. They are due to report on this once every two years.
Broader climate finance
The OECD data shows that the overall amount of climate finance – including funding for emissions cuts – provided by developed countries grew fast in 2023 before declining in 2024. In contrast, the amount of private finance developed countries say they “mobilised” increased in both 2023 and 2024, pushing the top-line figure to a record high.
While the OECD does not say which countries provided what amounts, data from the ODI Global think-tank suggests that the 2024 cuts to bilateral climate finance were spread broadly among wealthy nations.
Thwaites of NRDC welcomed the fact that overall climate finance provided and mobilised by developed countries exceeded $130 billion in both 2023 and 2024. He said that this was “well above earlier projections” and “shows that when rich countries work together, they can over-achieve on climate finance goals”.
But Sehr Raheja, programme officer at the Delhi-based Centre for Science and Environment, said these figures are “modest” when set against the new $300-billion goal.
“While the headline total figure of climate finance remains alright,” she said, “declining bilateral climate spending raises important questions about the predictability of high-quality, concessional public finance, which has consistently been a key demand of the Global South.”
She also lamented that loans continue to dominate public climate finance and that mobilised private finance is concentrated in middle-income countries and on emissions-reduction measures rather than adaptation projects. “Private capital continues to follow bankability rather than climate vulnerability or need,” she added.
Ritu Bharadwaj, climate finance and resilience researcher at the International Institute for Environment and Development, said the figures painted an outdated picture as climate finance has since declined as rich countries shrink their overseas aid budgets and increase spending on defence.
Last month, the OECD published figures showing that international aid – which includes climate finance – fell by nearly a quarter in 2025. The US was responsible for three-quarters of this decline. The OECD projects a further decline in 2026.
With Thursday’s climate finance report, the OECD is “publishing a victory lap for 2023 and 2024 at almost the same moment its own aid statistics show the funding base eroding underneath it,” Bharadwaj said.
