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 If the finding is repealed, it would “erase current limits” on greenhouse gas pollution from cars, factories and power plants, AP said.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.”

Palestine: Israel’s bombing has left Gaza vulnerable to climate change
Israel’s bombardment of Gaza during the conflict that broke out in October 2023 has wrecked progress towards adapting the enclave to climate change and left two million Gazans vulnerable to heatwaves, drought and disease, the Palestinian Authority (PA) said in a new climate plan submitted to the United Nations.
Palestine’s third nationally determined contribution (NDC), uploaded to the UN climate body’s website this week, says that while “the aggression on the Gaza Strip did not make the climate worse”, “it removed the housing, water and sanitation systems, health facilities, energy networks, roads and livelihoods through which people absorb a climate they were already struggling with.”
The 91-page document lists the types of infrastructure it says Israel has destroyed and notes how the destruction will worsen the impacts of climate change. It says the bombing of hospitals and rising hunger have make it harder for Gazans to cope with the health impacts of climate-driven heatwaves and waterborne diseases.
The destruction of water tanks, boreholes and desalination plants, meanwhile, have left Gazans struggling with the effects of water shortages and drought, while mass unemployment reduces people’s ability to afford climate-driven price rises. The erasure of most of the Strip’s homes makes it more difficult for people to avoid the sun’s increasing heat, the NDC said.
Many Gazans are now living in the ruins of collapsed buildings or in makeshift shelters and tents that offer little or no protection from high temperatures.
Palestine’s previous goals to cut emissions and adapt to climate change in Gaza, expressed in its last NDC five years ago, were based on a pre-war baseline that “no longer describes anything that exists”, the NDC says. Progress made since 2021 has now been destroyed, it adds.
Green reconstruction of Gaza
Instead of continuing to aim for these adaptation and emissions-reduction goals, the PA is now calling for the green reconstruction of Gaza. It says buildings should be constructed again in an energy-efficient manner with solar panels and served with modern water, waste and transport systems.
While the PA, controlled by the Fatah political party, continues to claim legitimate control of Gaza, the strip was effectively governed by Fatah’s rival Hamas between 2007 and the recent war. Control is now split between Israel and the political wing of Islamist militant group Hamas, after a US-backed ceasefire took effect in October 2025, although a UN-backed committee plans to take over.
The United Nations, European Union and World Bank have jointly estimated that Gaza needs $71.4 billion of investment in the next two years to recover and build back. This process should be Palestinian-led, they said in April.
But US President Donald Trump has said the US should “take over” and “own” Gaza and redevelop it as the “Riviera of the Middle East”. Israel’s right-wing prime minister Benjamin Netanyahu has said that Israel should control the territory with civil administration managed by Palestinians favourable to Israel.
With occupation, targets conditional
In the other part of Palestine, the West Bank, the Palestinian Authority carries out some government functions, but ultimate control rests with Israel, which has occupied the West Bank since 1967.
Because Israel controls planning in most of the West Bank, the NDC argues that the PA cannot pursue all the climate projects it wants. In addition, Israel restricts the movement of PA officials, making data collection difficult, and controls the West Bank’s electricity supply meaning that the PA cannot control whether it comes from dirty or clean sources of energy.
Given this situation, the NDC says that all of Palestine’s new climate targets are conditional but it will aim to reduce emissions 12.8% below a business-as-usual baseline by 2035 and 17.1% by 2040. If the Israeli occupation ends and Palestine regains full sovereignty over its land and resources, it will aim for reductions of 15.1% and 19.1% by 2035 and 2040 respectively under an “independence pathway”.
That could allow, for example, for greater electrification and reducing emissions per unit of growth, the document said.
To achieve the 2035 emissions-reduction target and adapt to the impacts of climate change, the PA says it needs $8.6 billion in total. This funding would be spent on measures like encouraging solar farms and rooftop solar and scaling up solar water heating to cover four-fifths of households. To complement the planned increase in solar power, the authority wants to modernise the electricity grid and install battery storage.
In the transport sector, it aims to promote the uptake of electric vehicles, develop bus rapid transit corridors and scrap old polluting trucks and buses. In Gaza in particular, it wants to deploy 66 electric buses when the conflict ends.

To adapt to climate-driven drought, the NDC includes initiatives to reuse wastewater through treatment plants, build desalination plants in Gaza to remove salt from seawater, and promote irrigation for farmers.
The new climate plan was prepared by Palestine’s Environment Quality Authority, with support from the United Nations Development Programme and the governments of Britain and Spain.
The United Nations recognised Palestine’s statehood in 2012 and it joined the UN’s climate convention and signed the Paris climate agreement – which requires countries to submit more ambitious NDCs every five years – in 2016.
The Israeli foreign ministry did not respond to a request for comment. But in late 2024, then Israeli climate envoy Gideon Behar told Climate Home News that the war and the resulting environmental destruction in Gaza was the fault of Hamas.

Climate Change
Analysis: UK solar power hits record high over summer 2026
Solar power generation in the UK reached a new record over the summer of 2026, as temperatures across the nation soared, according to new analysis by Carbon Brief.
Collectively over June, July and August, solar farms and rooftops generated 8.8 terawatt-hours (TWh) of electricity in the UK*, as shown in the chart below.

Speaking to Carbon Brief, Chris Hewett, chief executive of trade association Solar Energy UK welcomed the new record, adding that it was driven by “clear skies and continued growth in deployment”.
This surge in generation took place amid the hottest summer on record in the UK, with five heatwaves between May and August.
Summer 2026 was the sixth sunniest on record, with more than 620 hours of sunshine, according to the Met Office. England and Wales – which experienced the most extreme heat – saw their second-sunniest summers on record.
June 2026 was the hottest June in England since records began in 1884, according to Met Office data, while Wales and the UK as a whole experienced their second-warmest June.
It was the driest July for England and Wales since records began in 1836, with some parts of London seeing no rain at all in the month, while Wisley in Surrey had no rain for 62 days.
In England, temperatures peaked at 38.1C at Kew Gardens in London on 13 August.
According to the Met Office, this summer’s record mean temperature was made 130 times more likely by climate change.
Amid these hot and sunny months, solar power generation increased 23% from the same period in 2025. This is double the level of solar generation over the summer of 2021, according to Carbon Brief analysis.
While solar panels can be affected by periods of extreme heat, the longer hours of daylight and higher levels of irradiation over the summer more than offset any efficiency losses.
June, July and August all saw solar set new monthly records for solar generation – July saw the highest solar generation in a calendar month ever, with 3.3TWh meeting 15% of overall electricity demand for the month.
As of the end of August, the total UK solar generation in 2026 stood at 17TWh – 13% higher than the same point in 2025.
The number of solar farms and rooftop installations has grown substantially in recent years, helping to boost generation. Domestic rooftop solar accounts for around 29% of total capacity.
In 2025, the UK’s solar capacity reached 21 gigawatts (GW) by the third quarter of the year, according to UK government figures. This is a jump of 3GW, or 18%, year-on-year, as Carbon Brief reported in January.
(Capacity is the maximum output possible from an electricity generation, whereas generation is what was produced over a certain time period, such as a day, month or year.)
According to the University of Sheffield, the installed solar capacity is now nearly 24GW.
This includes nearly 172,000 solar installations that have been fitted across the UK since the start of 2026, according to recent government figures. In July alone, more than 19,800 rooftop solar panels were installed – the equivalent of one installation every two minutes.
In total, nearly 1.7m households in the UK now have solar panels installed.
Over 26 heatwave days this summer – periods of at least three days when temperatures exceed the Met Office’s county-level heatwave temperature threshold – UK households with rooftop solar panels avoided an estimated £86.7m in electricity costs, according to analysis by Utility Bidder.
Talking about the surge in solar generation this summer, Hewett says:
“[It] not only kept bills down for people with solar and batteries in their homes, but helped keep overall power prices much lower than they would have been if Britain had been relying on more gas generation during the day”.
Despite the record generation, no new half-hourly solar power output record was set in the summer of 2026. This still stands at 15.2 megawatts (MW) on 23 April 2026.

How this summer’s heat and drought impacted crops in Europe – in six charts
Farmers around Europe are dealing with the aftermath of a summer of extreme heat, drought and wildfires that were exacerbated by climate change.
Human-caused climate change is increasing the severity and likelihood of many extreme weather events around the world, which is increasing volatility for food producers.
This summer resulted in, for example, shrunken potatoes in the Netherlands, reduced carrot harvests in France, dried-up rice fields in Italy and scorched olive groves in parts of the Mediterranean region.
Global food prices are currently at their highest level since early 2023 due to “heatwaves and energy price dynamics”, according to the UN Food and Agriculture Organization.
Other factors such as blocked fertiliser supplies in the Strait of Hormuz and high fuel costs have also played a role in this year’s agricultural outputs.
In the six charts below, Carbon Brief provides a snapshot of the impact this summer’s extremes are considered to have had on crop production and yields across Europe.
1. Most EU countries expect to see declines in cereal production this year
2. Most countries are recording reduced crop yields
3. Around €2bn worth of cereal losses after June heatwave
4. UK yields of wheat, barley and oats are all due to drop in 2026
5. Maize production in France is due to hit a four-decade low
1. Most EU countries expect to see declines in cereal production this year

France, in particular, will see heavy losses in the amount of cereals – such as wheat, barley and oats – it produces this year, according to European Commission data.
French cereal production is expected to drop by almost 8 megatonnes (Mt) in 2026, compared to 2025.
The chart above shows that most European countries, aside from Bulgaria, will also see production losses this year.
Germany is due to see the second-largest losses in production, dropping by almost 4Mt compared to 2025.
Prof Til Feike, a cropping systems expert at the Julius Kühn-Institut, says many areas in Germany and Austria, as with other parts of Europe, have been “hit hard by a long-lasting dry period in combination with record-high heatwaves”.
This has resulted in dry grassland for animals and lower yields of maize, which is a “key fodder crop” for livestock. He tells Carbon Brief:
“In the long run, farming must adapt better to more extreme weather conditions, not only heat and drought, but also prolonged wet periods. So, there is no one-fits-all solution for climate change adaptation.”
2. Most countries are recording reduced crop yields
Heat and a lack of water have “substantially worsened” crop expectations this summer in western and most of central Europe, according to a recent bulletin from the EU Joint Research Centre.
Yields are expected to be “significantly reduced”, with local crop failures “likely” in areas such as France, southern Germany, northern and central Italy, and Hungary, it added.
The chart below shows that yields of cereal grains – which, here, refers to the tonnes of a grain grown per hectare of land – are expected to fall in most EU countries in 2026.

Slovakia, Austria and Hungary are expected to see the largest declines in cereal yields, reducing by more than one tonne per hectare in 2026 compared to 2025.
The recent EU bulletin noted that irrigated crops performed well in Portugal this summer – the country with the largest yield increases. Other crops relying on rainfall showed growing signs of heat stress, it added.
3. Around €2bn worth of cereal losses after June heatwave
The record heatwave that hit many parts of Europe in June contributed to an estimated €2-2.3bn in cumulative grain production losses, as shown in the chart below.

The intense June heat in western Europe would have been “virtually impossible” just 50 years ago, according to a rapid climate attribution study. It was the region’s hottest June on record.
The Energy & Climate Intelligence Unit (ECIU) thinktank analysed June and July 2026 grain forecasts from Coceral, a European grain traders association.
ECIU estimated lost supply by multiplying the change in tonnes of grains between these two months by prices for harvest delivery in 28 European countries.
Major grain producers France, Germany, Hungary and Spain accounted for 86% of the lost revenue, according to the ECIU.
Extreme heat is also expected to have a wider economic impact across the continent. Analysis from Triodos Bank found that this summer’s extreme weather could reduce the EU’s gross domestic product (GDP) by around 1% this year, or around €180bn.
4. UK yields of wheat, barley and oats are all due to drop in 2026
If current trends continue, the average yields for cereals and oilseeds will result in the UK’s worst harvest since detailed records began in 1984, according to ECIU.

Barley yields could fall by 15%, oats by 14% and wheat yields by 6% year-on-year, according to 2026 harvest surveys from the Agriculture and Horticulture Development Board, a non-departmental public body that provides agricultural data to the UK government.
ECIU said that, even if the situation improves, this year is still expected to be one of the five worst harvests on record. This means that four of the five worst harvests in the UK have occurred in the past decade.
Consumers will likely see higher prices and/or smaller vegetables in supermarkets as a result, Tim O’Malley, chairman of UK company Nationwide Produce, told BBC News in August.
Other crops, such as berries, have grown successfully in the extreme heat. But the Guardian noted fears this could dip later this year “as plants become exhausted from heavy cropping during the heatwave”.
5. Maize production in France is due to hit a four-decade low
France has been acutely affected by this summer’s extreme weather, with more than 7,300 excess deaths during heatwaves and a record number of weather stations recording temperatures of above 40C.
The country is the EU’s largest agricultural producer, but heat, drought and wildfires have affected many crops.
The chart below shows that maize production is set to drop by more than one-third (35%) year-on-year.

This could result in France’s lowest maize production since 1980, according to data from Agreste, the country’s agriculture ministry’s statistics service.
Due to the heat, “record-early” grape harvests have also been recorded in various parts of the nation since mid-July, reported Le Monde. In some cases, this means “smaller, less juicy grapes, which will yield less wine”, explained the newspaper.
6. Declines in EU grains since 2025

Overall in the EU, data and projections indicate declines in the output of cereal grains this year.
Cereal production is set to fall by 9% compared to 2025, according to the European Commission.
Just one year in the past decade – 2024 – recorded lower production levels.
Maize production is set to be particularly affected, with projections indicating a 13% drop, to 52Mt – the lowest level in the EU since 2007.
