At 12.33pm on Monday 28 April, most of Spain and Portugal were plunged into chaos by a blackout.
While the initial trigger remains uncertain, the nationwide blackouts took place after around 15 gigawatts (GW) of electricity generating capacity – equivalent to 60% of Spain’s power demand at the time – dropped off the system within the space of five seconds.
The blackouts left millions of people without power, with trains, traffic lights, ATMs, phone connections and internet access failing across the Iberian peninsula.
By Tuesday morning, almost all electricity supplies across Spain and Portugal had been restored, but questions about the root cause remained.
Many media outlets were quick to – despite very little available data or information – blame renewables, net-zero or the energy transition for the blackout, even if only by association, by highlighting the key role solar power plays in the region’s electricity mix.
Below, Carbon Brief examines what is known about the Spanish and Portuguese power cuts, the role of renewables and how the media has responded.
What happened and what was the impact?
The near-total power outage in the Iberian Peninsula on Monday affected millions of people.
Spain and Portugal experienced the most extensive blackouts, but Andorra also reported outages, as did the Basque region of France. According to Reuters, the blackout was the biggest in Europe’s history.
In a conference call with reporters, Spanish grid operator Red Eléctrica set out the order of events.
Shortly after 12.30pm, the grid suffered an “event” akin to loss of power generation, according to a summary of the call posted by Bloomberg’s energy and commodities columnist Javier Blas on LinkedIn. While the grid almost immediately self-stabilised and recovered, about 1.5 seconds later a second “event” hit, he wrote.
Around 3.5 seconds later, the interconnector between the Spanish region of Catalonia and south-west France was disconnected due to grid instability. Immediately after this, there was a “massive” loss of power on the system, Blas said.
This caused the power grid to “cascade down into collapse”, causing the “unexplained disappearance” of 60% of Spain’s generation, according to Politico.
It quoted Spanish prime minister Pedro Sánchez, who told a press conference late on Monday that the causes were not yet known:
“This has never happened before. And what caused it is something that the experts have not yet established – but they will.”
The figure below shows the sudden loss of 15GW of generating capacity from the Spanish grid at 12.33pm on Monday. In addition, a further 5GW disconnected from the Portuguese grid.

The Guardian noted in its coverage that “while the system weathered the first event, it could not cope with the second”.
A separate piece from the publication added that “barely a corner of the peninsula, which has a joint population of almost 60 million people, escaped the blackout”.
El País reported that “the power cut…paralysed the normal functioning of infrastructures, telecommunications, roads, train stations, airports, stores and buildings. Hospitals have not been impacted as they are using generators.”
According to Spanish newswire EFE, “hundreds of thousands of people flooded the streets, forced to walk long distances home due to paralysed metro and commuter train services, without mobile apps as telecommunications networks also faltered”.
It added that between 30,000 and 35,000 passengers had to be evacuated from stranded trains.
The New York Times reported that Portuguese banks and schools closed, while ATMs stopped working across the country and Spain. People “crammed into stores to buy food and other essentials as clerks used pen and paper to record cash-only transactions”, it added.
Spain’s interior ministry declared a national emergency, according to Reuters, deploying 30,000 police to keep order.
Both Spain and Portugal convened emergency cabinet meetings, with Spain’s King Felipe VI chairing a national security council meeting on Tuesday to discuss an investigation into the power outage, Sky News reported.
By 10pm on Monday, 421 out of Spain’s 680 substations were back online, meaning that 43% of expected power demand was being met, reported the Guardian.
By Tuesday morning, more than 99% of the total electricity supply had been recovered, according to Politico, quoting Red Eléctrica.
In Portugal, power had been restored to every substation on the country’s grid by 11.30pm on Monday. In a statement released on Tuesday, Portuguese grid operator REN said the grid had been “fully stabilised”.
What caused the power cuts?
In the wake of the power cuts, politicians, industry professionals, media outlets, armchair experts and the wider public scrambled to make sense of what had just happened.
Spanish prime minister Sánchez said on the afternoon of the blackout that the government did not have “conclusive information” on its cause, adding that it “[did] not rule out any hypothesis”, Spanish newspaper Diario Sur reported.
Nevertheless, some early theories were quickly rejected by officials.
Red Eléctrica, “preliminarily ruled out that the blackout was due to a cyberattack, human error or a meteorological or atmospheric phenomenon”, El País reported the day after the event.
Politico noted that “people in the street in Spain and some local politicians” had speculated about a cyberattack.
However, it quoted Eduardo Prieto, Red Eléctrica’s head of system operation services, saying that while the conclusions were preliminary, the operator had “been able to conclude that there has not been any type of intrusion in the electrical network control systems that could have caused the incident”.
The Majorca Daily Bulletin reported that Spain’s High Court said it would open an investigation into whether the event was the result of a cyberattack.
Initial reporting by news agencies blamed the power cuts on a “rare atmospheric phenomenon”, citing the Portuguese grid operator REN, according to the Guardian. The newspaper added that REN later said this statement had been incorrectly attributed to it.
The phenomenon in question was described as an “induced atmospheric vibration”.
Prof Mehdi Seyedmahmoudian, an electrical engineer at Swinburne University of Technology in Australia, explained in the Conversation that this was “not a commonly used term”.
Nevertheless, he said the phenomenon being described was familiar, referring to “wavelike movements” in the atmosphere caused by sudden changes in temperature or pressure.
In general terms, Reuters explained that power cuts are often linked to extreme weather, but that the “weather at the time of Monday’s collapse was fair”. It added that faults at power stations, power distribution lines or substations can also trigger outages.
Another theory was that a divergence of electrical frequency from 50 cycles per second (Hz), the European standard, could have caused parts of the system to shut down in order to protect equipment, France 24 explained.
Some analysts noted that “oscillations” in grid frequency shortly before the events in Spain and Portugal could be related to the power cuts. Tobias Burke, policy manager at Energy UK, explained this theory in his Substack:
“The fact these frequency oscillations mirrored those in Latvia…at the other extreme of the Europe-spanning ENTSO-E network, might suggest complex inter-area oscillations across markets could be the culprit.”
This phenomenon can be seen in a chart shared by Prof Lion Hirth, an energy researcher at Hertie School, on LinkedIn.
With many details still unknown, much of the media speculation has focused on the role that renewable energy could have played in the blackouts. (See: Did renewable energy play a role in the cut?)
Many of the experts cited in the media emphasised the complexity of determining the cause of the outages. Eamonn Lannoye, managing director at the Electric Power Research Institute Europe, was quoted by the Associated Press stating:
“There’s a variety of things that usually happen at the same time and it’s very difficult for any event to say ‘this was the root cause’.”
Nevertheless, there are several efforts now underway to determine what the causes were.
Portugal’s prime minister, Luís Montenegro, announced on Tuesday that the government would set up an independent technical commission to investigate the blackouts, while stressing that the problem had originated in Spain, according to Euractiv.
Finally, EU energy commissioner Dan Jørgensen has indicated that the EU will open a “thorough investigation” into the reasons behind the power cuts, BBC News noted.
Did renewable energy play a role in the blackouts?
As commentators began to look into the cause of the blackout, many pointed to the high share of renewables in Spain’s electricity mix.
On 16 April, Spain’s grid had run entirely on renewable sources for a full day for the first time ever, with wind accounting for 46% of total output, solar 27%, hydroelectric 23% and solar thermal and others meeting the rest, according to PV Magazine.
Spain is targeting 81% renewable power by 2030 and 100% by 2050.
At the time of the blackout on Monday, solar accounted for 59% of the country’s electricity supplies, wind nearly 12%, nuclear 11% and gas around 5%, reported the Independent.
The initial “event” is thought to have originated in the south-western region of Extremadura, noted Politico, “which is home to the country’s most powerful nuclear power plant, some of its largest hydroelectric dams and numerous solar farms.”
On Tuesday, Red Eléctrica’s head of system operation services Eduardo Prieta said that it was “very possible that the affected generation [in the initial ‘events’] could be solar”.
This sparked further speculation about how grids that are highly reliant on variable renewables can be managed so as to ensure security of supply.
Political groups such as the far-right VOX – which has historically pushed back against climate action such as the expansion of renewables – also pointed to the blackout as evidence of “the importance of a balanced energy mix”.
However, others rejected this suggestion, with EU energy chief Dan Jørgensen telling Bloomberg that the blackout could not be pinned on a “specific source of energy”:
“As far as we know, there was nothing unusual about the sources of energy supplying electricity to the system yesterday. So the causes of the blackout cannot be reduced to a specific source of energy, for instance renewables.”
Others have sought to highlight that, while it was possible solar power was involved in the initial frequency event, this does not mean that it was ultimately the cause of the blackout.
Writing on LinkedIn, chief technology officer of Arenko, a renewable energy software company, Roger Hollies, noted:
“The initial trip may well have been a solar plant, but trips happen all the time across all asset types. Networks should be designed to withstand multiple loss of generators. 15GW is not one power station, this is the equivalent of 10 large gas or nuclear power stations or 75 solar parks.”
Others pointed to what they said was insufficient nuclear power on the grid – a notion that prime minister Sánchez rejected, according to El País.
Speaking on Tuesday, he said that those arguing the blackouts showed a need for more nuclear power were “either lying or showing ignorance”, according to the newspaper. It said he highlighted that nuclear plants were yet to fully recover from the event.
One key aspect of the transition away from electricity systems built around thermal power stations burning coal, gas or uranium is a loss of “inertia”, the Financial Times highlighted.
Thermal power plants generate electricity using large spinning turbines, which rotate at the same 50 cycles per second (Hz) speed as the electrical grid oscillates. The weight of these “large lump[s] of spinning metal” gives them “inertia”, which counteracts changes in frequency on the rest of the grid.
When faults cause a rise or fall in grid frequency, this inertia helps lower the rate of change of frequency, giving system operators more time to respond, noted Adam Bell, director of policy at Stonehaven, in a post on LinkedIn.
Solar does not include a spinning generator, and therefore, critics pointed to the lack of inertia on the grid due to the high levels of the technology as a cause of the blackout.
As Bell pointed out, this ignores the inertia provided by nuclear, hydro and solar thermal on the grid at the time of the blackout, alongside the Spanish grid operator having built “synchronous condensers” to help boost inertia and grid stability.
Bell added:
“A lack of inertia was therefore not the main driver for the blackout. Indeed, post the frequency event, no fossil generation remained online – but wind, solar and hydro did.”
While the ultimate cause of the blackouts remains to be seen, they have highlighted the need for an increased focus on grid stability, particularly as the economy is electrified.
A selection of comments from experts published in Review Energy emphasises the need for further resilience to be built into the grid as it transitions away from fossil fuels.
How has the media responded to the power cut?
As the crisis was still unfolding and its cause remained unknown, several climate-sceptic right-leaning UK publications clamoured to draw a link between the blackouts and the nations’ reliance on renewable energy.
It comes as right-leaning titles have stepped up their campaigning against climate policy over the past year.
On Tuesday, the Daily Telegraph carried a frontpage story headlined: “Net-zero blamed for blackout chaos.”
But the article contradicted its own headline by concluding: “What exactly happened remains unclear for now. And the real answer is likely to involve several factors, not just one.”
None of the experts quoted in the piece blamed “net-zero” for the incident.
The Daily Telegraph also carried an editorial seeking to argue renewable energy was the cause of the blackouts, which claimed that “over-reliance on renewables means a less resilient grid”.
The Daily Express had an editorial (not online) claiming that the blackout shows “relying on renewables is dim”.
Additionally, the Standard carried a comment by notorious climate-sceptic commentator Ross Clark breathlessly blaming the blackout on “unreliable” renewables, with a fear-monguering warning that the “same could happen in the UK”.
The Daily Mail published a comment by Rupert Darwall, a climate-sceptic author who is part of the CO2 Coalition – an organisation seeking to promote “the important contribution made by carbon dioxide to our lives” – which claimed that the blackout showed “energy security is being sacrificed at the altar of green dogma”.
Climate-sceptic libertarian publication Spiked had a piece by its deputy editor Fraser Myers titled: “Spain’s blackouts are a disaster made by net-zero.” The article claimed that “our elites’ embrace of green ideology has divorced them from reality”.
In Spanish media, Jordi Sevilla, the former president of Red Eléctrica, wrote in the financial publication Cinco Días that, while it is not known what caused the blackout, it is clear that the country’s grid “requires investments to adapt to the technical reality of the new generation mix”. He continued:
“In Spain, in the last decade, there has been a revolution in electricity generation to the point that renewable technologies ([solar] photovoltaic and wind, above all) now occupy the majority of the energy mix. This has had very positive impacts on CO2 emissions, lower electricity prices and increased national autonomy.
“But there is a technical problem: photovoltaic and wind power are not synchronous energies, whereas our transmission and distribution networks are designed to operate only with a minimum voltage in the energy they transport. Therefore, to operate with current technology, the electrical system must maintain synchronous backup power, which can be hydroelectric, gas or nuclear, to be used when photovoltaic and wind power are insufficient, either due to their intermittent nature (there may be no sun or wind) or due to the lack of synchronisation required by the generators to operate.”
For Bloomberg, opinion columnist Javier Blas said that “Spain’s blackout shouldn’t trigger a retreat from renewables”, but shows that “an upgraded grid is urgently needed for the energy transition”. He added:
“The world didn’t walk away from fossil-fuel and nuclear power stations because New York suffered a massive blackout in 1977. And it shouldn’t walk away from solar and wind because Spain and Portugal lost power for a few hours.
“But we should learn that grid design, policy and risk mapping aren’t yet up to the task of handling too much power from renewable sources.”

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.”
