Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
‘Catastrophic’ climate impacts
RECORD HEAT: Western Europe experienced its hottest June on record – some 3C above average – according to analysis covered by the Guardian. It said the finding came “as the UK enters its third heatwave of the year and wildfires ravage France and Spain”. Le Monde said 10,000 people had been evacuated due to wildfires in southern France.
‘EXCESS DEATHS’: The June heatwave killed more than 2,700 people in France, according to a guest post analysis for Carbon Brief. Similar analysis for Germany said there had been more than 5,000 “excess deaths”, reported Bloomberg. Meanwhile, an ongoing heatwave in the US has killed at least 30 people, said USA Today.
STORM TEST: Floods have killed 39 people in Guangxi province in southern China, said state-run newspaper China Daily. Scientists warned that climate change and the weather phenomenon El Niño are exposing China to “catastrophic storms” that will test its resilience in 2026, reported Reuters. The nation’s latest official climate report found that “extreme weather and climate events…have become more frequent and severe”, said China National Radio.
Around the world
- EU ELECTRIFICATION: The European Commission is set to unveil a 2040 target for EU electrification on 17 July, reported Bloomberg. Citing a leaked draft, it said the plan would aim to cut oil use in half and gas use by two-thirds.
- PEAKING PLAN: China has published an “action plan” for peaking emissions during the 15th five-year plan period to 2030, reported Xinhua. It lists targets including “new energy vehicles” making up 30% of cars on the road by 2030, said Reuters.
- CLIMATE ‘FLAT EARTHER’: The Trump administration has appointed Matthew Wielicki, described by Politico as a “climate critic”, to lead the office in charge of the US national climate assessment. Common Dreams quoted a scientist describing the move as “like putting a flat-earther in charge of NASA”.
- UGANDAN SUIT: A group of farmers from Uganda have launched a legal suit in London against the East African oil pipeline, according to Climate Home News.

Captured

Carbon Brief explained – via eight facts – why air conditioning rates in some parts of Europe are relatively low, as the technology emerges as a new front in the global “culture war” over climate action. Analysis for the article illustrated that, in many parts of the world’s fastest-warming continent, air conditioning simply was not needed in the past.
Spotlight
COP31 president speaks to Carbon Brief on electrification
This week, Carbon Brief interviews Murat Kurum, president-designate of the COP31 UN climate talks in November and Turkey’s minister of environment, urbanisation and climate change, on his target to boost global electrification.
Carbon Brief: You recently launched a target for 35% of the world’s final energy to come from electricity by 2035. Where did this idea come from?
Murat Kurum: The “35 by 35” target is grounded in technical data and based on the IEA [International Energy Agency] and IRENA [International Renewable Energy Agency] analysis of what is needed to keep [the 1.5C Paris Agreement target] within reach. The level was not chosen politically. Rather, it reflects what the science and the energy modelling tell us is required.
CB: Why do you think an electrification target is important right now?
MK: The case for the target is urgent right now. The latest war in the Gulf has made energy diversification – and, in particular, renewable energy transition and electrification – a top global priority, because it is the surest and cleanest way to protect citizens around the world from high and volatile energy prices.
At a time of real fragmentation in international relations, a single, shared target is needed to focus global efforts by aligning governments, businesses and investors behind a common benchmark and to send a clear market signal.

CB: Which countries are supporting this target so far?
MK: The reaction so far has been extremely positive and, while we presented our target at the UN June climate meetings in Bonn, our earlier conversations with parties at both the Petersberg and Copenhagen climate dialogues paved the way for this launch.
For example, the EU, UK, and Canada have welcomed the target, as have the Brazilian COP30 and Ethiopian COP32 presidencies. All have confirmed it will be central to discussions at COP31.
This support has been reflected in the business community as well, with polling by the We Mean Business Coalition showing that 90% of businesses expect to have largely electrified their operations by 2035 and that 88% expect electrification will make their business more competitive.
CB: How do you hope and expect to see this taken forward at the COP? Could it be in the formal COP outcomes, or part of the second global stocktake?
MK: We are now taking electrification forward as an “action agenda” initiative to bring actors together and drive progress. The action agenda and the [formal COP] negotiations are separate, but complementary, with different processes and thresholds, and it is too early to say what all countries might be able to agree in the negotiations. That is for parties to determine as the year progresses.
We are focused and determined to use COP31 as a moment to spark a global conversation about electrification.
CB: What are the key priorities for reaching the target?
MK: The critical sectors for reaching the target are buildings, transport and industry, which together account for around 45% of global emissions. Financial support for the developing world and investment in grids and infrastructure is also crucial.
The target also builds on COP28’s target to triple renewable energy capacity and seeks to take advantage of the tumbling cost of renewable power and other technologies critical to the energy transition. This is a journey that Turkey itself is taking ambitious steps on, including our plan to reach 120GW [gigawatts] of renewable capacity by 2035.

‘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.”

Correcting climate ‘misperceptions’ may not boost climate action
The general public often underestimate support for climate action, while overestimating the real-world actions taken by other people to address the problem, according to new research.
The study, published in Nature Climate Change, explores the differences between people’s support for climate change, their behaviour and their assumptions about other people’s behaviour.
It is based on multiple surveys of more than 5,000 people across Germany and the US.
The study expands on previous research on how the general public systematically underestimate the climate commitment of their peers.
The difference between actual and perceived support for climate action among the public is sometimes known as a “perception gap”.
The surveys tested how people’s perceptions of climate attitudes and behaviours relate to their own willingness to contribute and undertake “climate-friendly” actions.
One of the authors tells Carbon Brief that this perception gap is not due to “ignorance or bias”, but because “people are just not good at making good estimations”.
The research also reveals that people’s opinions and behaviours are more “nuanced than previously assumed” and suggests that simply “correcting misperceptions” does not automatically lead to greater climate action.
Measuring climate actions
The study notes that correcting the perception gap is often seen as a “cost-effective” way to promote public engagement and drive action to reduce the intensification and impacts of climate change.
Most studies that explore the perception gap have primarily focused on surveys that have asked people to report their willingness to support climate change.
In other words, researchers have relied upon people saying they would support efforts to tackle climate change, rather than measuring people’s real-world actions, such as financial donations, attending protests or changing their behaviour.
To fill this gap, the researchers behind the new study surveyed a total of more than 5,000 people in Germany and the US over 2024-25. Surveys were split across five different experiments, each focused on public perceptions of climate attitudes and how they relate to individuals’ actual behaviour:
| Experiment | What they did |
| Survey one | Participants were asked if they were willing to donate 1% of their household income to WWF – and then were given the chance to do so. Follow-up questions asked participants to predict how many of their peers said “yes” and how many actually donated to the charity. |
| Survey two | Participants read a constitutional complaint against the German government, led by Greenpeace, which demands for stricter climate policies. They were asked if they were willing to participate as a claimant and/or donate to the cause – and then were given the chance to do so. Follow-up questions asked participants to predict how many of their peers said “yes” and how many went on to support the complaint. |
| Survey three | Participants were requested to complete an online “work for environmental protection task” where the more “pages” they completed resulted in more donations to WWF. They then predicted how many pages their peers completed. Participants also rated their individual behaviours and support for eight climate policies and then estimated the same for other people. |
| Surveys four and five | Participants were split into three groups that were either informed that 4% of participants had donated 1% of their household income to WWF, that “68% were willing to contribute” or given no information. They then had to state whether they were willing to support WWF and then were given the opportunity to do so. |
The authors note that Germany and the US are two of the “top 10 CO2 emitters” and are places where climate action is “especially necessary”. However, they add that the two countries are not reflective of “diverse cultural contexts” and further research is needed across the world.
The perception gap
The researchers find that most of their participants supported climate action, but much fewer actually performed verifiable behaviours.
For example, survey one finds that 37% of participants said they were willing to donate to WWF, yet just 4% did when given the opportunity.
Participants generally overestimated the climate actions of their peers, predicting that 23% of other people donated. Willingness, on the other hand, was slightly underestimated with respondents averaging around 34%.
The results from survey three suggest that this perception gap is likely due to general cognitive processes within the human brain that make accurate estimations about large groups difficult, say the authors.
The chart below shows the actual percentage of people who supported different environmental policies and performed climate-friendly behaviours (blue dots) compared to average predictions from the surveys (red dots).
They reveal a “consistent pattern” where “small proportions were overestimated and large ones were underestimated”, the authors say, driving predictions towards the middle. This phenomenon is known as “regression to the mean”.
In other words, where public support for a policy was high, participants in the survey estimated it was lower than it was. When the support was lower, estimates would be higher.

The study finds that individual and environmental factors played a role in shaping people’s perceptions of their peers’ climate actions, which were distinct from general misestimations.
For example, people who were already involved in climate action, had more frequent climate discussions and consumed more climate-focused news and media predicted a higher proportion of climate support “across the board”.
The results from the fourth and fifth surveys show that knowing the context of other people’s beliefs and behaviour in surveys can impact the attitudes of participants.
Participants that were told that 68% of people were willing to donate 1% of their household income to the WWF were more willing to donate.
In contrast, participants that were told that 4% of people actually donated did not report more willingness to “discuss climate change, sign petitions or donate” than the control group.
However, there was no obvious impact on actual donations for any of the three groups, the study notes.
Lead study author Dr Kevin Tiede, scientific managing director of the Institute for Planetary Health Behaviour at the University of Erfurt, tells Carbon Brief that the findings suggest that “just telling people how many people support climate action is likely not enough to really change something”.
However, Tiede adds that “direct comparability” between people saying they would donate and actually donating is “limited” and that giving people more time to answer and autonomy over where to donate might result in more people taking action.
‘Pluralistic ignorance’
Tiede explains that the study findings demonstrate the existence of “pluralistic ignorance”, where a person believes their own views differ from the majority.
For climate change, this means that the “vast majority of people around the world support climate action, but people considerably underestimate the extent of this support”, the study says.
However, the surveys reveal that pluralistic ignorance “in the climate domain” is more nuanced than previously thought, say the authors.
Prof Madalina Vascleanu, an assistant professor at Stanford University’s Doerr School of Sustainability, who was not involved in the study, tells Carbon Brief that encouraging climate action is complex.
It may take multiple and repeated “attempts” at effective communication, or for people to directly “experience” the “norm” that climate change is widely supported, she says, rather than simply being told.
“Observable” behaviours, such as “identity signalling” – which could involve anything from protesting to vegetarianism – might have more of an impact on encouraging climate action among peers than “private behaviours like donations”, she adds.
The study is a “great addition to the literature”, Vascleanu says, because “correcting” the perception gap did not have an effect on climate-friendly behaviour, as “scholars had previously assumed”. She adds that it has “sparked several new hypotheses” that her “lab is now working on”.
Prof Mauro Bertolotti, associate professor of social psychology at the Università Cattolica del Sacro Cuore, explains that the “attitude-behaviour gap” revealed by the research is a “rather common finding”.
However, he is “sceptical” of the “simplified and abstract” measures, warning that experiment environments often come with “assumptions and expectations” that are different from real life.
As a result, they might not “replicate” the process people go through when choosing to “make a donation to an environmental cause”, he says.
‘Targeted’ communication strategies
The researchers argue that it is more effective to focus on “targeted” communication strategies – encouraging climate-friendly behaviours that aim to reach the majority who already support climate action, rather than trying to convert climate sceptics.
They call for attention to be paid to the attitude-behaviour gap between people saying they support efforts to tackle climate change and following up with real-world climate actions.
The study suggests strategies for decision-makers to reduce the attitude-behaviour gap, such as “facilitating climate-friendly behaviour” with “convenience and subsidies”. They also recommend ensuring environmental policy prioritises fairness to gain visible and widespread public support.
They add that the public would benefit from understanding the “effectiveness and co-benefits” of climate action.
