Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Trump to overturn ‘endangerment finding’
EPA OVERTURNING: The Trump administration announced its plan to overturn the 2009 finding that has been the “central basis” for US action to regulate greenhouse gas emissions, the Associated Press reported. A new Environmental Protection Agency proposal would rescind the “endangerment finding”, which determined that carbon dioxide and other greenhouse gases endanger public health and welfare, according to the newswire. If the finding is repealed, it would “erase current limits” on greenhouse gas pollution from cars, factories and power plants, AP said.
‘MISLEADING’ REPORT: The proposal is supported by a new Department of Energy report that uses “misleading and inaccurate” statements to argue that climate science has “overstated” the risks of a warming planet, Politico reported. The report, which also argues that climate science is “underestimating” the societal benefits of burning fossil fuels, was written by five scientists who “are known” for “denying accepted climate science”, the outlet added.
‘WINDMILL DISGRACE’: Wind development on federal lands and waters may be halted by the Trump administration, Bloomberg reported. Interior secretary Doug Burgum ordered a comprehensive review of the agency’s approval process, it said. According to Renewable Energy News, the department said more than 3.5m acres offshore were designated as “wind energy areas” by the last administration and that “terminating” these areas is “safeguarding” local environments and economies from “unchecked development”. This followed from Trump’s recent comment that “windmills are a disgrace”, the publication added.
Floods and heatwaves
SEVERE FLOODING: Torrential rains triggered a devastating flood in northern Nigeria, leaving at least 23 people dead, Deutsche Welle reported. The flooding has displaced 5,560 people and left dozens injured, according to the National Emergency Management Agency. More than 200 people have been killed in floods in Nigeria since the start of the rainy season in May this year, according to DW. The outlet reported that scientists have said climate change is fuelling many of these extreme weather occurrences.
BEIJING RAINS: China faced “another deadly rainy season” after 60 people were killed following days of torrential rain in Northern Beijing, reported Reuters. The outlet said climate change has made extreme weather “more frequent and intense”. Elsewhere, floodwaters from the Indus and Chenab rivers have “inundated” more than a dozen villages across Pakistan’s Punjab province, said India’s Tribune.
RECORD TEMPERATURE: Japan recorded its hottest day on record as temperatures reached 41.2C in southwest Tokyo, Al Jazeera reported. There were 16 heat-related deaths and more than 10,800 people were hospitalised with heatstroke last week, the outlet said. Meanwhile, the Iraqi government issued an official holiday in seven of its provinces as temperatures topped 50C, said Gulf News.
‘MILLIONS’ INSIDE: Temperatures soaring in the US have led to “millions” of Americans being warned to stay inside as some areas reach 48.8C, noted Newsweek. Heat warnings and advisories have been issued by the National Weather Service, according to the outlet.
Around the world
- ENERGY PLEDGE: The European Union has pledged to buy $750bn of energy from the US in exchange for a lower tariff rate under its trade deal with Trump. “Significant purchases” of US oil, liquified natural gas and nuclear fuel to replace Russian fossil fuels are included in the deal, CNBC reported. The Financial Times quoted energy experts saying the deal is a “pie in the sky” given that “US fossil fuel supplies [in 2024] to the bloc accounted for just $75bn”.
- COP30 COSTS: The UN held an “urgent meeting” over “sky-high” accommodation costs ahead of the COP30 climate summit in Brazil, Reuters reported. Meanwhile, the last US climate negotiators have been fired by the Trump administration, leaving the nation with “no official presence” at the summit, said CNN.
- ‘MELTING RAPIDLY’: Glaciers in Turkey’s southeast are melting rapidly due to rising global temperatures “amid human-caused climate change”, Al Jazeera reported.
- ‘SEWAGE CRISIS’: The US and Mexico have signed a deal to end the Tijuana “sewage crisis”, committing to update outdated wastewater infrastructure to handle higher flows triggered by worse flooding, said Inside Climate News.
- RENEWABLE ENERGY: Australia’s government has pledged to “substantially increase” its renewable energy underwriting scheme following concerns the nation will struggle to meet its 2030 power target, noted the Guardian. Meanwhile, New Zealand’s government has voted to resume gas and oil drilling despite an “outcry” from the opposition and environmental groups, reported the New Zealand Herald.
- ‘UNHELPFUL TUSSEL’: UN climate chief Simon Stiell paid a visit to Australia and urged the nation and Turkey to resolve their “long-running tussle” over who will host the COP31 summit, calling the delay “unhelpful and unnecessary”, Reuters reported.

Captured

New analysis by Carbon Brief this week revealed that 2025 is on track to be the second or third hottest year on record. The chart above draws on data from five different research groups that report global surface temperature records to illustrate how 2025 saw the second-hottest first half of the year on record.
Spotlight
‘Thirst’ exhibition maps the water crisis
This week, Carbon Brief visits a London exhibition exploring the world’s worsening water crisis.
Intricate ink drawings on cotton paper explore interconnected issues in Nepal.
Global warming has melted glaciers in the region, causing flooding and infectious diseases, displacing human and non-human life.
Yet, through his drawings, Nepalese artist Karan Shrestha has created a mosaic of the Himalayan region that shows water as a signifier of extreme weather and a life-giving source to be shared.

His piece, “Water-giver, memory-keeper and the shifting forces”, is displayed at the Wellcome Collection for its “Thirst: In Search of Freshwater” exhibition.
Brought together by Wellcome curator and lecturer Janice Li, it features 125 objects that showcase the impact of climate change on water and its role in shaping health and ecosystems.
Li’s research into the etymology of “thirst” unravelled a global interpretation of water, reflecting the exhibition’s geographical breadth. She told Carbon Brief:
“Humans have faced really brutal and critical environmental crises and have, through a really deep innate knowledge of their own specific land, been able to devise monumental infrastructure to combat the crises they face.”
Just before Shrestha’s art in the exhibition are photographs taken by M’hammed Kilito.
In one picture, Kilito’s guide, Mustapha, looks into a dried-up well in a Moroccan oasis.
Climate change and human activities have resulted in the loss of two-thirds of oases in the country, according to information displayed at the exhibition.
Speaking about the photograph, Kilito told the Guardian that it looked like Mustapha was “praying for the return of something essential: water”.
Water adopts multiple faces in the exhibition: a vital yet scarce resource in certain pieces, a spiritual entity in others – and a destructive force.
Nothing makes the latter as clear as “Deluge” by photojournalist Gideon Mendel. Five screens display footage of the aftermath of severe floods around the world, captured by Mendel over 17 years.

Li told Carbon Brief:
“[Gideon] told me that, in the last two years, there’s always been a flood of that magnitude happening somewhere. He didn’t imagine that one day it would get to a point where he would have to choose which one to go to.”
Next to “Deluge” is a dome-like space where visitors can sit on bean bags and listen to glaciers melting in the Himalayas.
Though the exhibition confronts global water challenges, Li hopes it also reminds visitors of the resource’s beauty:
“Quite a few people told me they sit in the listening room for half an hour, really enjoying themselves and then guilt hits them because they’ve forgotten they’re listening to melting ice. But, this is the beauty of art, and a lot of beauty has come out of decay, destruction and deterioration because it also, sometimes, signals rebirth.”

Climate Change
Why COP30 is critical for Australia and the Pacific
1. A Global Response Plan to address the 1.5°C emissions gap
Right now, countries’ new climate pledges — their Nationally Determined Contributions (NDCs) — still fall far short of what’s needed to keep global warming below 1.5°C. If governments don’t step up, the world is on track to blow past this critical limit, with devastating consequences for Australia, the Pacific, and the entire planet. We can’t wait for another review cycle — COP30 must deliver a strong, credible Global Response Plan that drives urgent action.
To kickstart this, world leaders at the start of COP30 need to send a clear message: the energy transition is happening, fossil fuels are on the way out, and closing the emissions gap is non-negotiable.

The 29th UN Climate Conference, COP29, takes place in Baku, Azerbaijan, from 11 to 22 November 2024. Greenpeace is at the COP to hold governments to account to make fossil fuel polluters pay for the climate crisis they have created, and put fossil fuel phase out plans at the heart of national climate action.
2. Protect Forests and Biodiversity
Forests are vital for life and climate stability — yet global pledges to protect them are fragmented and weak. COP30 must deliver a five-year Forest Action Plan to halt and reverse deforestation by 2030 and bring together all international efforts under one clear roadmap.
Biodiversity and climate are two sides of the same crisis. Addressing one without the other risks harm. COP30 must unite the three Rio Conventions on climate, biodiversity, and desertification so nature and people thrive together.

3. Make Polluters Pay and Fund Climate Action
A lack of finance is blocking progress. COP30 must create a strong accountability plan for the new global climate finance goal — starting with US$300 billion and scaling to US$1.3 trillion — ensuring funds reach First Nations, local communities, and vulnerable nations. Governments must back polluter-pays reforms so big emitters fund real climate solutions, not greenwash.

4. Towards a Pacific-Led COP31
A Pacific COP is a historic opportunity for bold climate leadership. Australia must ensure Pacific voices shape every decision — from closing the 1.5°C gap to phasing out fossil fuels and securing fair finance.
COP31 must also deliver a fast, fair fossil fuel phase-out — turning words into concrete action and signalling the end of coal, oil, and gas.

Climate-hit nations hail loss and damage fund’s debut call for proposals
Developing countries hit by extreme weather, rising seas and other climate change impacts have been asked to submit proposals for support from the Fund for Responding to Loss and Damage (FRLD) for the first time, three years after its birth at COP27 in Egypt.
Under the debut call for proposals launched at COP30 in Belém, the fund’s board said $250 million would be available for projects seeking to address a wide range of climate-related losses – from damaged infrastructure to the loss of cultural heritage, or community displacement.
Announcing the launch of the fund’s activities, FRLD Co-Chair Jean-Christophe Donnellier said the initial call for funding requests would help “test, learn and shape the fund’s long-term model”. Fellow Co-Chair Richard Sherman said it “sends an important signal to developing countries that support is available”.
Countries will be able to submit their proposals starting in mid-December for six months through to mid-June, with funding approvals beginning in July next year.
Evans Njewa, chair of the Least Developed Countries Group at the climate talks, hailed the call for proposals as “a practical step toward justice, long awaited by communities on the frontlines”, adding that the loss and damage fund “must now deliver fast, simple and accessible support”.
Demand set to outpace resources
Activists fear that could be difficult, however. They say the fund is badly short of resources and will not be able to meet the enormous needs of developing countries.
By 2030, they could require $200 billion-$400 billion a year to address loss and damage caused by storms, droughts, flooding, extreme heat and rising seas made worse by climate change, according to an Independent High-Level Expert Group on Climate Finance.
However, developed countries have only pledged $788 million, signed commitments for over $560 million, and actually transferred less than $400 million of that total.
Tax luxury air travel to fund adaptation and loss and damage
Climate activist Harjeet Singh, founding director of India’s Satat Sampada Climate Foundation, said that as climate impacts wreak havoc on countries including the Philippines and Jamaica – where Hurricane Melissa is estimated to have caused up to $7 billion in loss and damage – the FRLD “is starting with a fraction of the scale required”.
Singh said the operationalisation of the fund three years after it was agreed showed it had failed to function as a rapid response mechanism.
He called for the fund to correct its course to match “the scale of the crisis, not the scale of political convenience”.
“The countries and communities facing the worst consequences – those who had no role in causing this crisis – deserve more than an empty shell. This is not climate justice,” Singh said.
Acknowledging the need for more resources to meet the vast scale of need on the ground, Ibrahima Cheikh Diong, the FRLD’s executive director, said the fund will keep working “to mobilise additional resources to support our long-term ambitions”.
Rising call for L&D support in climate plans
Demands for the fund to expand support are reflected in the national climate plans (NDCs) submitted by developing countries to the UN climate body in the run-up to COP30.
South Africa, Vanuatu, Mauritius and Liberia are among those that have laid out demands for loss and damage support from the FRLD, emphasising that climate impacts in their countries have exceeded the limit to which they can adapt.
South Africa – which suffers prolonged droughts, destructive floods and heatwaves – said climate change is already causing “irreplaceable loss”, damaging cultural heritage sites and hurting Indigenous knowledge systems. It is also shrinking farmland, hitting economic growth and worsening health outcomes, including more heat-related illness and deaths, the country said in its NDC.
With support from the FRLD, South Africa plans to improve how the country records and understands the full impact of climate disasters, including collecting detailed information on who is affected, with particular consideration for women and marginalised groups, so that relief and rebuilding programmes can be more effectively targeted, its NDC said.
For Mauritius, climate-related disasters in 2024 caused losses equivalent to 0.07% of gross domestic product (GDP), and the country plans to seek support from the FRLD for recovery and disaster response systems in sectors including agriculture, fishing, housing and health.
The island country said it planned to use the resources to implement a Climate Compensation Fund mechanism to compensate for loss and damage in terms of personal belongings, loss of lives and inability to work due to climate-related disasters. It also plans to improve the country’s disaster response capacity by equipping emergency relief centres with food and other vital supplies.
The inclusion of loss and damage in countries’ NDCs “makes it clear that there is a cost, which must be covered”, said Mattias Söderberg, global climate lead at DanChurchAid, a Danish NGO.
“We can decide if we want to invest in [emissions] mitigation and adaptation, but when it comes to loss and damage, there is no option. When climate-related disasters happen, communities will have to respond,” he added.

Climate is MIA in Australia and Turkiye’s bids to host COP31
Catherine Abreu is the Director of the International Climate Politics Hub
In a move straight out of the movies, the UN Secretary-General’s High Level Climate Event in September put the two prospective hosts for the 2026 global climate talks, Türkiye and Australia, back-to-back in the speaking order.
Both President Erdogan and Prime Minister Albanese confidently welcomed the world to their countries for COP31. Here at COP30, the drama continues, with the Australian and Turkish Pavilions sitting side-by-side while neither country seems prepared to step back from their bid. Get your popcorn.
Except this isn’t the movies, it’s the UN-led, multilateral process charged with helping us save ourselves from runaway climate change. And, thus far, what has been conspicuously missing from the pseudo-dramatic showdown between these two potential hosts is any meaningful discussion about how either country would aim to use its presidency of the climate talks to accelerate action on climate change, in their own country or globally. The drama, it would seem, has been misplaced.
Any country wanting to host the annual UN summit on climate change should be making the case for doing so based on their climate credentials – and their climate ambition.
While some past COPs may have made us forget this, the energy and intent of current COP President Brazil, and the conversation Brazil’s COP presidency has generated at home about the country’s climate action, serve as useful reminders of what we should be striving for in the host of the climate talks.
It would be disappointing not to have a solid plan in place for COP31 and risk losing the momentum Brazil will hopefully have generated by the end of COP30.
COP host criteria
So, what should we be looking for in a COP host? First, we need a prospective presidency to be clear about the conversations they envisage mediating in the run-up to and during their summit and how those will help us advance a just and equitable transition away from fossil fuels toward renewable energy and energy efficiency, within the framework of the Paris Agreement.
We need a COP presidency focused on the question of how they can use their platform to help improve countries’ abilities to respond to the impacts of climate change and address the losses and damages they are experiencing.
We need a presidency fully engaged with using their platform to secure commitments to provide the finance countries need to take climate action and respond to climate impacts, while advancing the need to transform global financial systems so that we are tackling the problem of climate change at its core, rather than deepening it.
Finally, and perhaps most importantly, we need a host ready to commit their COP to being an effective space for negotiating, deliberation and decision making that is free from the undue influence of actors who are there to slow us down.
In other words, is the potential host ready to commit to a COP led by science and traditional and Indigenous knowledge? Are they prepared to ensure transparent accreditation processes that will expose conflicts of interest? And are they prepared and competent to facilitate an effective COP structure so that parties are given the opportunity to have the conversations they need to have, and to land the outcomes they need to achieve, without the influence of anticlimate lobbyists in their midst? If the answers to all of these questions are not a resounding yes, this is not the Presidency we need.
Moreover, a potential COP host should be prepared to use their global platform to substantially advance climate action on the domestic level.
In the case of Australia, that should involve being steered by the wider Pacific leadership on just and equitable transitions away from fossil fuels. As the second largest coal exporter in the world and with a domestic energy mix that includes both fossil fuels and booming renewable energy growth, Australia can and should be aiming to credibly lead conversations on export market transformation and power system transitions to ethical renewable energy and improving energy efficiency.
For Türkiye, affirming a direction of travel away from coal dependency is key. So far Türkiye has been opposed to this both domestically and internationally; indeed, it did not sign up to the tripling renewables pledge at COP28, even though that target was aligned with Türkiye’s own renewable targets, because the text referred to “coal phase-down”. Türkiye moving past its opposition and opening up to a dialogue on a just transition away from coal would be a significant victory for the climate.
There are many reasons a country may want to host the UN climate summit. Foremost among those reasons, and at the heart of the UN process that decides COP hosts, should be the drive to lead national and global conversations that make a real difference in tackling the climate crisis.
