China has seen a series of temperature records broken this summer, as heatwaves have struck various regions across the country.
Between mid-March and mid-July 2025, it was hit by an unprecedented number of “hot days” – where temperatures reach or exceed 35C – according to the China Meteorological Administration (CMA) .
In both May and June, heatwaves swept across northern regions, with temperatures in Xinjiang reaching as high as 46.8C.
Such a record-breaking summer is becoming increasingly common, with the CMA’s annual Climate Bulletins showing that hundreds of local heat records have been surpassed over the past decade.
The CMA says that “extreme high temperatures” have shown an “increasing trend” in China since its records began in 1961.
Experts tell Carbon Brief that heatwaves strongly affect public health, agricultural output and economic activity.
They also put significant strain on the electricity system.
In this Q&A, Carbon Brief looks at how heat extremes are changing in China, the role of climate change in making these worse and how the country is adapting to the impacts.
How are heat extremes changing in China?
The latest science report from the Intergovernmental Panel on Climate Change (IPCC) states that it is “virtually certain” that “the frequency and intensity of hot extremes have increased” across the world since 1950.
The IPCC adds that it is “virtually certain” that human-caused greenhouse gas emissions are “the main driver”.
China is no exception. In a press release for its latest 2025 “blue book on climate change in China”, the CMA says China is “susceptible to the impacts of global climate change”, noting:
“[China’s] warming rate is higher than the global average…and extreme weather and climate events are becoming more frequent and intense.”
Data from the CMA’s Climate Bulletins show how the average annual temperature in China is rising and how 2024 was the hottest year on record, as shown in the chart below.
While 2024 was the hottest year on record overall, this was a result of consistently high temperatures throughout the seasons.
At a CMA press conference in 2025, Chan Xiao, deputy director of the CMA commented:
“Temperatures were consistently high throughout the year, with significant fluctuations in temperature during winter. Spring, summer and autumn temperatures were all record highs for the same period.”
In contrast, more heat records were broken during 2022, even though it was not quite as hot overall. Explaining this, Prof Yang Chen from Chinese Academy of Meteorological Sciences, which falls under the CMA, tells Carbon Brief:
“[For] the annual mean air temperatures, every day counts. So even if the 2022 was exceptional for its large number – actually also very long duration-consecutive days and high-magnitude – of hot extremes, mainly during summer and in the Yangtze River Valley, it does not mean the remaining days were hotter than the counterparts in 2024.”
The CMA defines a “hot day” or “high temperature day” as one that reaches or exceeds 35C. It adds that “high temperatures for several consecutive days constitute a heatwave”.
As the global climate has warmed, the number of “hot days” that China is experiencing has been on the rise, shown in the figure below.
The year 2022 set a new record, with meteorological stations in China recording an average of 16.4 hot days. This was 7.3 more than the average for 1991-2020. The year 2024 came close to this record, with 15.6 hot days. These two years have also seen China’s hottest summers on record.
In 2022, more than 1,000 meteorological stations in China reported heatwaves, with 441 breaking “historical records”. For 2024, 74 stations reported “consecutive high temperature days” and 81 of them broke records.
Xiao said at a press conference in 2023 that “continuous high temperatures” in China’s central and eastern regions lasted for 79 days in the summer of 2022. The provinces of Gansu and Xinjiang in north-west China, Hubei in central China and Sichuan in south-west China all reported their “highest temperatures since 1961”.
In addition, the “maximum daily temperature [in the summer of 2022] at 361 national meteorological stations – accounting for 14.9% of the total number of stations in the country – reached or exceeded historical extremes”, Xiao added.
The CMA has also highlighted that summer is arriving earlier for much of China. In 2024, for example, summer in regions including most of Hainan province in south China, central Yunnan province in south-west China as well as central and southern Xinjiang province in north-west China arrived more than 20 days earlier than average.
“If a year’s spring and summer are longer, the potential heatwaves…will also be longer,” Prof Wenjia Cai, from the department of earth system science of Tsinghua University, tells Carbon Brief.
Cai notes that there are more ways to define heatwaves than CMA’s absolute threshold of 35C.
For example, a heatwave can also be defined by how long the hot weather persists, or based on “the daily maximum temperature, daily average temperature, or even nighttime temperature”, she tells Carbon Brief.
However, regardless of the definition used, the “number of heatwave days is definitely increasing as a result of climate change”, she adds.
What role does human-caused climate change play?
A field of climate science called “attribution” has emerged over the past two decades to establish the role that human-caused warming plays in individual extreme weather events, including heatwaves, floods, droughts and storms.
Attribution studies can also be used to find the “fingerprint” of human-caused climate change in longer-term trends, such as the gradual increase in surface temperatures over multiple decades.
Heat is the most-studied extreme event in attribution literature, as it is mainly driven by thermodynamic influences – in other words, it is relatively easy to study.
In contrast, storms and droughts are more strongly affected by complex atmospheric dynamics and, as such, can be trickier to simulate in a model. Cai tells Carbon Brief:
“High temperature is the most obvious trend against the background of climate change. Heatwaves, in comparison to events such as rainfall and typhoons, are also more predictable.”
Carbon Brief has produced an interactive map showing every attribution study published up to November 2024. In total, 114 extremes and trends in China have been the subject of an attribution study, including more than 20 relating specifically to extreme heat.
One study included on the map looks at the change in the intensity and frequency of extreme temperatures across China over 1951-2018. The authors say that, over this time period, “more intense and more frequent warm extremes” were observed across “most regions” in China – and that “greenhouse gas forcing plays a dominant role” in this.
Looking at individual extreme events, one analysis by the “rapid attribution” group World Weather Attribution investigates the then-record-breaking heat across China in July 2023. The analysis says that temperatures exceeded 50C in north-west China, adding that Sanbao, in Xinjiang, hit 52.2C on 16 July of that year.
The study finds that, in a world without climate change, such an extreme heat event would have been “extremely rare” and would only have happened once every 250 years. However, in today’s climate, as a result of human-caused climate change, a heatwave of this intensity is now expected once every five years.
This means China’s extreme heat of July 2023 was 50 times more likely due to climate change. The study also finds that in a world without climate change, the heatwave over China would have been 1C cooler.
A separate study finds that human-caused climate change also caused a more than 60-fold increase in the likelihood of the extremely warm 2013 summer, compared to the early 1950s.
It adds that other factors such as urbanisation and changes in atmospheric circulation patterns can also make heat extremes more intense and frequent.
What impact are these heatwaves having?
Heatwaves have a wide variety of impacts on human activities, such as public health, crop yields and economic output.
Older people are particularly vulnerable to extreme heat. The 2024 report from the Lancet Countdown on Health and Climate Change found that, in 2023, demographic changes alone could have driven a 65% increase in heat-related deaths among over-65s, compared to the 1990-99 average.
Cai, who is also the lead author of the Lancet Countdown’s China report, tells Carbon Brief that older people are the “most commonly mentioned vulnerable group” and that the number of people affected by heatwaves will grow as societies age.
However, heatwaves also “affect outdoor activities” regardless of age group, she adds, as well as having impacts on sleep and allergies:
“We don’t want anyone to think they are in a group of people unaffected by heatwaves.”
Cai says that heat exposure can increase the incidence of certain dangerous behaviours, such as domestic violence, as well as a wide range of diseases – including cardiovascular diseases and respiratory diseases – and mental health disorders.
In 2023, more than 30,000 deaths were related to heatwaves in China – 1.9 times higher than the average over 1986-2005, according to Cai and her colleagues’ China report.
This was a result of increased heat exposure – the average number of “heatwave exposure days” per person reached 16 days in 2023, more than three times the historical average (1986-2005), the report adds.
A 2022 attribution study on China notes that extreme heat can also increase the risk of preterm births. The authors find that over 2010-20, an average of 13,262 premature births were recorded in China due to heatwave exposure. The study linked one-quarter of these early births to climate change.
Another profound impact of heatwaves is that they can exacerbate droughts, with knock-on impacts for agriculture.
Reuters reported last June that “China’s agriculture ministry said…searing temperatures have adversely impacted summer planting and that fighting drought and protecting summer planting were arduous tasks”.
Droughts in 2024 hit more than 11 million people in China, with more than 1.2m hectares of affected crops and direct economic losses topping nearly 8.4bn yuan ($1.2bn), the Ministry of Emergency Management said in early 2025.
Heat-related economic losses could reach nearly 5% of China’s GDP by 2060, according to a recent guest post for Carbon Brief. Authors Prof Guan Dabo and doctoral student Sun Yida from Tsinghua University wrote:
“By 2060, China’s heat-induced economic losses could total about 1.5% of total GDP under 1.5C of global warming, 3% under 2C of warming and 4.9% under 2.5C of warming.”
Those predicted losses include “indirect economic losses”, which “could be due to changes in production, consumption or employment” in the global supply chain, including crop failures and labour slowdowns, they explained.
The figure below, based on their study, shows Chinese GDP losses under three different scenarios of future emissions, called “shared socioeconomic pathways” (SSPs).
The SSP1-1.9, SSP2-4.5 and SSP5-8.5 scenarios project average global temperature rises of around 1.5C, 2C and 2.5C by mid-century, respectively.
Economic losses are split into indirect losses (dark blue), labour losses (blue) and health losses (light blue).
Sectors such as the extractive industries, construction and non-metallic manufacturing “could see the highest losses” of about 4.6-6.4% of their “value-added” – the increase in worth of a product or service as it moves through different stages of production – largely because they are in Chinese “regions with significant warming”, according to Guan and Sun.
Those industries also have close business connections with south-east Asia, Africa and South America, which are “expected to face heightened exposure to production volatility caused by high temperatures”, they add.
The total economic loss globally could reach up to 4.6% by 2060, according to their study, and manufacturing-heavy countries such as China and the US, in particular, could be “strong[ly] hit”.
Other than manufacturing, electricity supplies in China have also been frequently reported to be affected by hot days.
Chinese news outlet China Business Network reports that China’s National Energy Administration said last year that summer was the hardest time to ensure sufficient electricity supply during a year and that extreme weather would make the supply even harder.
For 2025, China’s State Grid Corporation expected maximum electricity demand to exceed 1,200 gigawatts (GW), a new record.
Dr Muyi Yang, senior energy analyst at thinktank Ember, tells Carbon Brief that “when temperatures soar, electricity demand spikes – mainly due to air conditioning – and that can stretch the grid, especially in already tight systems”.
Biqing Yang, energy analyst at Ember, adds:
“In the third quarter of last year, for example, China’s residential electricity consumption rose significantly, by 17.8% year-on-year, largely due to elevated temperatures…It is clear that we are now entering an era [w]here climate change is having a real-time impact on our energy system.”
China’s electricity demand reached a new record in July 2025 after year-on-year growth of 8.6%, consuming more power in one month than Japan did in all of 2024, according to David Fishman, Shanghai-based principal at consultancy the Lantau Group.
The “staggering” July 2025 figures – including another 18% year-on-year rise in residential demand, partly due to rising household incomes, as well as air conditioning use – illustrates the impact of climate change on China’s power sector, Fishman writes on LinkedIn:
“We know it’s hot out and everyone knows every summer the intense heat seems to last for longer and longer. But these power consumption numbers are telling a story about China’s climate patterns like few other datasets can…and it’s a scary story.”
Yang, Chen and Cai tell Carbon Brief that it is important for China to adapt to the rising temperature and intensive heatwaves.
Chen specifically describes “successful” forecasts and early warnings as “critical” , saying that they are the “very first step toward adaptation”.
In his LinkedIn post, Fishman notes that the rapidly rising demand for electricity, including as a result of growing air conditioning use, also poses a “considerable challenge to China’s ability to meet rising demand solely with clean power sources”.
How is China adapting to heatwaves?
In recent years, China has implemented more and more policies aimed at adapting to heatwaves.
For example, weather forecasts and heatwave alerts have been provided.
Central and local governments have also issued labour policies aimed at protecting workers against extreme heat.
Under a policy from the Ministry of Human Resources and Social Security, for instance, outdoor works are not expected to be undertaken when temperatures exceed 40C. In addition, outdoor working hours should be shorter than six hours when the temperature is 37-40C.
Similarly, school students in some cities, such as Wuhan and Chengdu, have been advised to study from home during hot days in recent years.
Since 2021, the city of Tianjian has been sending text warnings of heatwaves to its residents, reminding people of the health risks it poses. The messages, according to Southern Metropolis Daily, warn that strokes might be triggered in the coming hot days and advises people to avoid outdoor activities and take medication if needed.
These text reminders have “significantly” reduced the number of hospitalised people in Tianjin, saving the city 140m yuan ($19.5m) since being introduced, adds the outlet.
In 2013, the central government published its first “national climate change adaptation strategy” – an attempt to implement the “clear requirement” of “enhancing our ability to adapt to climate change” included in the 12th “five-year plan” (2011-15).
In the latest version for 2035, heatwaves appear in sections related to the power sector, as well as agriculture and health.
The strategy aims to “improve” and “reinforce” nationwide “labour protection standards”, as well as “work system[s] that adapt to change and reduce agricultural disasters”. Its purpose is also to ensure the energy and electricity sectors’ abilities to “withstand extreme weather and climate events” in relation to heatwaves.
The strategy says that “health-risk assessment guidelines” and public health-related “implementation plans for adaptation under major extreme weather and climate events”, such as heat and heatwaves,in “various regions”, will be developed.
Last year, following the release of the latest overall adaptation strategy, China published the “national climate change health adaptation action plan (2024-30)”.
Cai calls the document a “very very important” blueprint for health risk management, bringing together a range of organisations, including hospitals, to form a “system related to climate change and health” that has “monitoring and early warning capabilities”.
She adds that this plan will also see heat-health alerts being issued nationwide:
“It is worth mentioning that the National Administration of Disease Control and Prevention and the China Meteorological Administration signed a joint agreement [in May 2025] on issuing [nationwide] health alerts – and that the first product is related to heatwaves.”
Ember’s Yang says that in terms of electricity, China is moving toward building a “‘new electricity system (新型电力系统)’ that is more compatible with high shares of renewables”. But, he adds, the old “planning psychology” needs to change so that it can better cope with extreme heat:
“Traditionally, the mindset has been very supply-driven – just keep adding enough generation and network capacity to meet demand…[With the new system] the demand side has to become an active player – a prosumer – that can actually support grid reliability.
“For example, during extreme heat, instead of just ramping up supply, we should also be encouraging users to reduce or shift their electricity use during peak hours, using price signals or incentives…This is the essence of what we call ‘coordinating generation, grid, load, and storage’ (源网荷储一体化) – a system that works together [and works] more efficiently and flexibly.”

Q&A: How China is adapting to ‘more frequent and intense’ heat extremes
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.”

‘Ride the wave of momentum’: Australia announces once-in-a-decade Marine Parks Network review
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.”
