This week
Long hot winter
‘WORLD’S WARMEST’: Record heat has affected “everywhere from northern Siberia and central and north-west America to parts of South America, Africa and Australia” this winter, reported the Financial Times. BBC News reported that last month was the world’s warmest February “in modern times”, the ninth month in a row to be the hottest on record since June 2023. This puts the world temporarily above the 1.5C threshold, noted the Guardian.
‘WEIRD’ WINTER HEAT: The New York Times reported that the “fingerprints of climate change” were detectable on the “weird” winter heat, including in Iran’s capital city Tehran, which was 4.2C warmer than average during the winter months. Morocco experienced the hottest January since measurements began, the country’s meteorological department told Agence France-Presse, at 3.8C above normal.
SMOKEHOUSE SCAR: Record winter heat continued to fan the flames of the “largest wildfire on record” in Texas, reported Axios. It added the blazes had left “a burn scar so large it is clearly visible from space”. Known as the Smokehouse Creek fire, it has burned more than 1.2m acres and “killed two people and thousands of cattle”, reported BBC Future. The publication explained that the fire has a “complex link” with climate change.
China’s pivotal ‘two sessions’ meeting
WHAT, WHEN, WHERE: China’s “two sessions” meeting, which sees the annual parliamentary gathering of the National People’s Congress and the Chinese People’s Political Consultative Conference, is currently underway in Beijing, Carbon Brief’s China Briefing newsletter reported. Its centrepiece is the “government work report”, a speech traditionally delivered by the premier that outlines priorities for the year ahead.
CLIMATE TARGETS: One of the few quantitative climate targets China set in the report is to reduce energy consumption per unit of GDP by 2.5% over the coming year, a goal that Bloomberg described as “modest”. The target was lower than analysts’ expectations of 4%, the outlet added.
FOSSIL FUELS REMAIN: The work report also restated a commitment to boosting fossil fuels in the name of “energy security”, Reuters reported. The newswire noted that China also aims to step up exploration of “strategic minerals”.
Around the world
- SURPRISE SNOW: Pakistan experienced unusual snowfall and heavy rains, resulting in the death of at least 35 people, including 22 children, reported BBC News.
- CORAL BLEACH: The world is on the brink of a fourth global mass coral bleaching event, which could see many tropical reefs killed by extreme ocean temperatures, reported Reuters. The Guardian reported that Australia’s Great Barrier Reef is facing its fifth mass coral bleaching event in eight years.
- FUNDING THREAT: Individuals from global south climate groups that depend on finance from the German government “feel unable to criticise Israel’s military action in Gaza” due to pressure from their German-funded employers, Climate Home News reported.
- MISSING MONEY: A UN official said that “Africa will be $2.5tn short of the finance it needs to cope with climate change by 2030”, noted Reuters, despite the continent producing the lowest emissions and experiencing the worst effects.
- NEW ZEALAND LAWSUIT: An elder of the Ngāpuhi and Ngāti Kahu tribes “won the right to sue seven New Zealand-based corporate entities”, including fuel, coal and gas companies and dairy exporters, for their contribution to climate change, noted the Guardian.
- NOTHING TO SEE HERE: The UK’s spring budget announcement was one of the “least green budgets in recent years” experts told the Guardian, with disappointment around electric vehicles and North Sea oil and gas. Carbon Brief had all the details.
2 billion
The amount of land in hectares that has been degraded by human activity over the past 500 years, reported Bloomberg.
Latest climate research
- A Nature Climate Change study found that, while climate change drives population growth in lizards “when trees are present”, deforestation could reverse this effect and even exacerbate the negative impacts of climate change.
- Under an additional 1C of warming, around 800 million people in the tropics will live in areas where “heavy work should be limited for over half of the hours in the year” due to the heat, a One Earth review paper found.
- The severe “Tinderbox drought” in southeast Australia, which preceded the country’s largest wildfires on record from 2019-20, was intensified by human-caused climate change, according to a Science study.

Captured

A victory for Donald Trump (red line) in November’s US presidential election could lead to an additional 4bn tonnes of greenhouse gas emissions by 2030, compared with Joe Biden’s plans (blue line), new Carbon Brief analysis revealed. It is based on an aggregation of modelling by various US research groups. For context, 4bn tonnes of greenhouse gases is equivalent to the combined annual emissions of the EU and Japan, or the combined annual total of the world’s 140 lowest-emitting countries. “Regardless of the precise impact, a second Trump term that successfully dismantles Biden’s climate legacy would likely end any global hopes of keeping global warming below 1.5C,” the analysis added.
Spotlight
Female climate activist Angel Arutura

On International Women’s Day, Carbon Brief speaks to Angel Arutura, a social and climate justice activist in Northern Ireland passionate about “connecting people and the planet” through social media.
Carbon Brief: How long has environmental activism been part of your life?
Angel Arutura: I’ve always been interested in the world around me, but it goes back to school, where geography was a subject that grabbed me. My teacher made lessons engaging and I became interested in how different parts of the world are affected by issues. I think my mixed-race heritage also helped. I have a multifaceted identity so, naturally, it made sense for me to think about how actions from the global north affected communities in the global south. I’m half Irish, half Zimbabwean, so I’ve been able to see that not just from an academic standpoint, but an emotional standpoint. Since then, I’ve been committed to connecting people to our true nature of love and protection and harbouring that loving connection for the people and the world around us.
CB: How has your identity as a woman shaped your activism, particularly your identity as a Black woman?
AA: I really started being vocal with my activism around the time of the Black Lives Matter protests in 2020, where the conversation was heavily on social justice. Growing up in a 98% White country, I experienced a lot of racism and my experience as a Black woman living in Ireland has been overwhelmingly negative. I rejected my Zimbabwean culture, my heritage, for so long. I went through a transformation at 17 where I started to connect with my heritage and it was through those years of self-reflection that I was able to speak at the protests. That’s when I found my voice. But, I thought to myself, hold on. Why are we just talking about social justice here? From then, I talked about the intersectionality of climate and social justice. As a Black woman, the driving power behind this was, in a weird way, finding that self-love.
CB: Why is it important to lift up the voices of women, particularly women of colour, when it comes to climate change?
AA: The majority of the time, when people talk about climate change and sustainability, they only talk about the exploitation of the planet. Think about fast fashion and women’s rights violations, and how those brands do sustainability initiatives and all this greenwashing. But how can you talk about the exploitation of the planet and not also the exploitation of women in the global south? The climate crisis, social justice, women’s rights, it’s all interconnected. An intersectional approach is the only one we need to take when it comes to climate change. It’s imperative if we want to create real, sustainable change. One of the best ways we can do this is through storytelling, in particular, elevating and uplifting the voices of the most vulnerable, especially those from the global south. And, unfortunately, that is women.

UN chief warns climate crisis “in overdrive” as El Niño threatens to fuel the fire
The United Nations Secretary-General and foreign ministers from the UK, France and Spain have blamed the deadly wildfires engulfing Europe on climate change, using the disaster to renew calls for faster cuts to greenhouse gas emissions.
António Guterres told journalists on Friday that the “climate crisis is in overdrive”, adding that global heat seen so far is just a “warm up act” as a phenomenon known as El Niño intensifies “adding fuel to a planet already on fire”.
A new World Meteorological Organisation (WMO) report published on Friday predicts that the weather pattern will grow into a “strong event” between now and October, increasing the risk of higher than normal temperatures across much of the world and disrupted rainfalls.
“That risks shattering every seasonal record – and driving even more severe effects worldwide,” Guterres said.
El Niño builds on top of an already warming world, driven primarily by the burning of fossil fuels. A WMO scientist, who did not want to be named, told journalists that all the heatwaves and other climate impacts seen so far this year are “before the effects of El Niño are really kicking in at a global scale”.
Fossil fuellling the fires
Fires have broken out across much of Europe but are threatening the most people in the south-west of France near Bordeaux and in Central Spain near Madrid. Nearly a quarter of a million people have been evacuated in France with hundreds of homes destroyed while in Spain 80,000 people have had to leave their homes and at least 13 died in one village.
A scientific study published on Friday by the World Weather Attribution group found that man-made climate change made deadly fires in France twice as likely and those in Spain twenty times more likely. Smaller fires in the UK were not analysed by the study.
UN Climate Change leader Simon Stiell blamed fossil fuels for the fires, as well as storms in Chile and heatwaves in North America and Japan in recent weeks. “The climate alarm is blaring”, he said on Wednesday.
Guterres criticised new fossil fuel production projects and fossil fuel subsidies for causing hardship across the world. Discussing his speech, a senior UN official – who did not want to be named – said the subsidies amounted to trillions of US dollars a year and criticised pension funds and institutional investors, including insurance companies, for continuing to invest in fossil fuel projects.

Asked why world leaders and the public are not prioritising climate action, Guterres said they are distracted by wars in Ukraine, the Middle East, Sudan and elsewhere and sometimes forget “other aspects that are a sometimes even more dangerous threat”.
Also the fossil fuel industry and “some countries” are campaigning to pretend that climate change does not exist, he said, adding that the UN should be more active in “naming the situations as they are and the responsibilties as they are and mobilising the public opinion”.
After meetings in Paris and Madrid earlier in the week, the UK’s new foreign minister Ed Miliband issued joint statements with his French and Spanish counterparts – Jean-Noël Barrot and José Manuel Albares Bueno – calling on the world to reduce its dependence on fossil fuels.
They promised to do more to reduce emissions and protect their people and encouraged other governments to do the same.
The UK-French statement called on governments to publish UN climate plans, known as nationally determined contributions (NDCs), which are aligned with the Paris Agreement’s goal to limit global average temperatures to 1.5C above pre-industrial levels.
According to Climate Action Tracker, only three countries – the UK, Nigeria and Norway – have submitted NDCs with 2035 emissions reduction targets which are compatible with 1.5C. Fifty-two countries – including Egypt, Vietnam and Argentina – have yet to submit an NDC at all.
Defending science
Beyond action on emissions, the ministers also intervened in an ongoing dispute over the timing of the Intergovernmental Panel on Climate Change’s (IPCC)’s next flagship assessment.
Miliband and Barrot’s statement said they “underline the importance” of scientific report feeding into governments’ next global stocktake of progress on climate action in two years’ time, calling it a “critical input” to that process.
The timing of this report has been a contentious issue in government negotiations at the IPCC and at June’s climate talks in Bonn. While a group of nations calling themselves the “friends of science” want the report before the stocktake, others like Saudi Arabia and India have argued that this would make the report of a worse quality and less inclusive of developing countries’ scientists.
Science ‘under attack’ from fossil fuel interests at UN climate talks
The UK-Spanish statement weighed in less explicitly on this issue but said that they “recall the importance of scientific evidence and acknowledge the work of the IPCC in this respect.”
The British and French ministers said they would seek to accelerate reductions of emissions in methane, a particularly potent greenhouse gas, at COP31 in November. They encouraged governments “to work jointly to develop a marketplace for fossil fuels with near-zero methane intensity.”
Methane leaks from oil, gas and coal production are a major contributor to global warming. Over a 20-year period, methane traps around 80 times more heat than carbon dioxide.

The UK and Spanish statement emphasised the importance of supporting the Global South and underlined the need to mobilise sustainable financing “at scale with the challenge we face”. The previous UK government, in which Miliband was energy minister, cut climate finance to developing countries to pay for increases in military spending.
The UK government led by new Prime Minister Andy Burnham has yet to outline any major changes to climate finance in its two weeks in power but has announced it will convert some finance from grants to loans in order to free up money to subsidise bus travel in England.
More adaptation needed
Guterres said that “it is time to stop treating each disaster as an isolated tragedy and recognise the systemic risk that is unfolding before our eyes.” A recent study found that three-quarters of UK media reports about the British June heatwave did not mention climate change.
As well as reducing emissions, the UN Secretary-General called for measures to adapt vulnerable people to extreme heat. Specifically, he said that buildings should be built and retrofitted for extreme heat and that every city and country should have heat-health action plans and early warning systems. Over 250 cities have joined the UN’s ‘beat the heat’ initiative, he said.
The Portuguese diplomat called for governments and employers to do more to protect their workers from heat, criticising global fashion brands for not setting heat standards for the factories that supply them. “No one should have to risk their life to earn a living,” he said.

‘Ride the wave of momentum’: Australia announces once-in-a-decade Marine Parks Network review
In response to the federal government announcing its once-in-a-decade review of Australia’s Marine Parks Network, the following lines can be attributed to Elle Lawless, Senior Campaigner at Greenpeace Australia Pacific:
“Greenpeace Australia Pacific welcomes today’s announcement that the Albanese Government will review Australia’s Commonwealth Marine Parks Network. This is a rare, once-in-a-decade opportunity to strengthen our marine parks and ban industrial fishing in Australia’s marine protected areas.
“Australians would be appalled to know that more than half of Australia’s Marine Parks Network currently allows for extractive industries, like longlining, bottom trawling and oil and gas mining. These so-called ‘protected’ areas were designed to safeguard our beloved ocean wildlife and underwater ecosystems – that is what Australians expect. Damaging industrial industries should not be given a free pass to trawl, fish, drill or extract from our marine parks.”
“With the first Ocean COP just around the corner, and off the back of Australia’s move to ratify the Global Ocean Treaty earlier this year, the Australian government has a unique opportunity to ride the wave of this momentum and solidify itself as a true global ocean leader.
“Greenpeace Australia Pacific is calling for industrial activities to be banned from our protected waters and for at least 30% of Australia’s ocean to be protected as ocean sanctuaries. This review presents a rare opportunity to create more ocean sanctuaries, true blue havens where ocean life can recover, thrive and repopulate the surrounding waters.”

Factcheck: No, Europe is not having its ‘quietest’ year for wildfires
In recent days, prominent climate sceptics and rightwing commentators have shared charts on social media incorrectly implying that Europe is having its “quietest” year for wildfires in 2026.
These include Dr Matthew Wielicki, a former University of Alabama geochemist and self-described “professor in exile”, who was recently appointed by the Trump administration to lead the US Global Change Research Program.
However, these charts paint a misleading picture as they are skewed by encompassing the entirety of Russia in the data – including the vast plains of Siberia.
These charts also use data that include fires that are deliberately lit to manage cropland, which is a declining practice across much of Europe.
In this factcheck, Carbon Brief shows that the area burned by wildfires across the European Union in 2026 is second only to 2022 for this time of year.
The latest data from the European Forest Fire Information System (EFFIS) also shows that France has set a new modern record for area burned and Spain’s wildfire season is among the worst on record.
The fires have displaced more than a third of a million people across south-western Europe, while an impending heatwave has also raised fears of the fires worsening in the coming days.
‘Quietest year’
On 27 July, as wildfires raged across multiple European countries, former Conservative peer and climate-sceptic commentator Matt Ridley posted on Twitter that “2026 is the quietest year for wildfires in Europe by some distance”.

Ridley, who sits on the academic advisory council of the Global Warming Policy Foundation (GWPF), a UK-based climate-sceptic lobby group that refuses to reveal the sources of its funding, was responding to an article by Daily Telegraph columnist Tim Stanley.
Stanley’s column, headlined: “Climate change is real – and the right needs to get serious about it”, warned:
“This is no longer a matter of speculation: the wildfires of Europe, pitiless and persistent, are the way we live now.”
Ridley included a chart from Our World In Data, showing the cumulative area burned by wildfires by week for Europe. The chart puts 2026 as having the smallest area for this time of year in a dataset going back to 2012.
Ridley’s post was widely shared by prominent rightwing figures – including Richard Tice, deputy leader of the hard-right, climate-sceptic Reform UK party, former Conservative cabinet minister Jacob Rees-Mogg and multiple commentators.
Separately, Wielicki also shared a chart on Twitter to imply that wildfires in Europe are declining. Wielicki has previously claimed that the “science is not settled on climate change”.
The charts posted by Ridley and Wielicki both use data from the Global Wildfire Information System (GWIS). The GWIS category for “Europe” encompasses all the countries on the continent and includes the whole of Russia.
As a result, Russia accounts for about 74% of the area included in the GWIS definition of “Europe”.
Wildfires in Russia typically account for 80-90% of the burned area in the GWIS Europe dataset. In 2026, fires in Russia are substantially below average. Therefore, including Russia in this comparison creates the false impression that wildfire activity across Europe is unusually low.
Dr Calum Cunningham, a research fellow at the University of Tasmania’s Fire Centre, says that such claims are “highly misleading”, noting that “they rely on aggregating fire activity across an enormous and climatically diverse region”. He tells Carbon Brief:
“A relatively quiet season in Russia can easily mask an exceptionally active season in France or Spain. If the analysis is focused on the regions actually experiencing the current fires, the picture is very different.
“The reality is that western Europe has experienced an extraordinary sequence of climate conditions this year.”
In contrast, the EFFIS provides a subset of wildfire data specifically for the area covered by the 27 nations of the EU, which, therefore, excludes Russia.
Another difference between the two datasets is that GWIS monitors all fires – including those on agricultural land that are intentionally set alight. The burned area as measured by GWIS contains significant cropland area.
By contrast, EFFIS uses land-cover data and other information to filter specifically for forest fires.
Looking at the EU-only data from EFFIS reveals that Europe is far from having its “quietest” year. The bloc’s burned area, as of 29 July, is almost 435,000 hectares (ha) – second only to 2022 for this time of year.

Notably, Wielicki has actually continued to post charts based on GWIS data, even after acknowledging that “includ[ing] all of Russia, including vast areas of Siberia…isn’t a good proxy for Europe”.
French fires
Even looking at EU-wide data misses the scale of this year’s wildfires for some individual countries.
The chart below shows the surge in burned area in France since mid-July.
For much of the first half of the year, the country was having a wildfire season that was only slightly above average in terms of total burned area. However, a notable uptick began in the first week of July.
The third week of the month saw France break its previous cumulative annual record by more than 19,000ha. That gap has widened as the fires continue to burn; as of 29 July, the cumulative burned area in France during 2026 was nearly 24,700ha above the previous record.

The fires in France follow a record-breaking June heatwave that “dried out vegetation across the region, allowing fires to spread quickly”, wrote the New York Times.
On 27 July, French president Emmanuel Macron called a “crisis cabinet meeting” in order to address the fires “ravaging several areas of south-west France”, said France 24.
More than 220,000 people have been evacuated due to the Gironde fire, west of Bordeaux, in “what may be France’s largest peacetime evacuation”, reported the Associated Press.
In the Conversation, Cunningham and two other University of Tasmania researchers write that evacuation orders “protec[t] human lives, but makes it more likely houses and other structures will burn if there’s no one to defend them”. They add:
“There is little doubt climate change has made France and Spain’s wildfires worse. They represent yet another reason to redouble our efforts to tackle climate change and stabilise our climate.”
Central Spain scorched
While Spain’s fire season has not broken records in the same way that France’s has, it is on track to be among the worst since EFFIS began reporting data in 2006.
The chart below shows the rapid increase in burned area in Spain since 8 July. The latest data from EFFIS reveal that, as of 29 July, Spain has almost matched its previous record at this point in the year. It is also nearly five times the average area burned for this time of year.

In Spain, the wildfires have been concentrated in the central part of the country, near Madrid.
BBC News reported that the fires outside the capital have burned “an area more than twice as large as the city itself”.
Nearly 90,000 people were forced from their homes in central Spain by the fires, said the Associated Press.
Pedro Sánchez, Spain’s prime minister, called the fires a “painful expression” of climate change.
Meanwhile, the UK, French and Spanish governments have issued joint statements this week in response to the fires. The UK/Spain statement begins:
“This summer’s wildfires demonstrated that climate change was now a national security emergency facing Europe and threatening our way of life.”
