Spain's fires broke records in June and kept going. By mid-July, a blaze in the Fontainebleau forest near Paris prompted France's biggest aerial firefighting response on record — and an arson investigation. Then fires in Ávila and Madrid merged into one monster blaze that officials called possibly the largest in Spain's modern history. France's Gironde-Landes fire generated a pyrocumulonimbus cloud with lightning and forced 4,000 people off the Atlantic coast on Tuesday alone. The EU dispatched planes, helicopters, and ground teams to both countries — and then its civil protection coordinator said the mechanism was "out of capacity." A fourth Spanish heatwave is arriving today, with temperatures forecast to reach 42°C by midweek. Spain's interior minister said Tuesday that "the coming hours will be absolutely decisive." Three very different arguments about what caused all this are now a genuine political fight.

The Climate Made This Inevitable

Pedro Sanchez and European scientists say these fires are the predictable result of a climate that the data showed was getting more dangerous every year.

These fires were predictable from the temperature record. Spanish PM Pedro Sanchez visited firefighters outside Madrid and said the crisis is "the most painful manifestation of a climate emergency that is making wildfires more voracious and heatwaves more frequent." He's called for a national "State Pact in the face of the Climate Emergency" and a new government scientific panel.

The numbers are stark. June 2026 was the hottest June ever recorded for Western Europe — 3.06°C above the modern average, per the Copernicus Climate Change Service. Spain received just 12.4 mm of rain in June, 39% of its normal total. France saw 3.4 times its annual average fire count this year; Spain, 1.7 times its average.

Scientists have a name for what results. Prof. Domingos Xavier Viegas at the University of Coimbra, Europe's leading wildfire specialist, calls them "sixth-generation fires" — blazes so intense they generate their own wind systems. Direct suppression is impossible above 10 megawatts per meter of fire front. Recent fires hit 60 MW/m — six times that threshold. Viegas says they're likely to become increasingly common as climate change intensifies.

Nine in Ten Fires Here Start With a Human

French Interior Minister Laurent Nuñez points to 162 arson-related arrests and says the math is simple: heat and drought explain why a fire spreads, not why it starts.

People start 9 out of 10 wildfires in France — campfires, unextinguished cigarettes, negligence, or deliberate arson, according to French authorities including the Ministry of Agriculture. Heat and drought explain why a fire spreads. They don't explain why it starts.

The Fontainebleau fire near Paris was likely deliberate. Interior Minister Laurent Nuñez said investigators found "about 10 fire ignition points within a perimeter of 1,000 meters," a pattern he said "suggests that it could have been deliberately set." Two people were formally indicted, including a volunteer firefighter. Police arrested an 18-year-old with soot on his hands and a lighter.

Since July 6, France has made 162 arson-related arrests. President Macron responded with a direct threat: "We are going to be intractable in the treatment and judicial follow-up, wherever there is negligence as well as criminals." Deliberately starting a wildfire in France carries up to 15 years in prison.

Europe Built Its Own Tinderboxes

Scientists and land managers say decades of suppressing small fires — and EU restoration rules that limit clearing — have left forests dangerously loaded with fuel.

Suppressing small fires makes the big ones catastrophic. Wildfire expert José Miguel Pereira at the University of Lisbon put it plainly: "We're actually saving fuels to have them burn under the most severe meteorological conditions." When every small fire gets extinguished, undergrowth builds up. When conditions finally defeat suppression, there's nothing to stop a megafire. Proven methods exist — controlled burns, clearing undergrowth, reintroducing grazing animals — but the Christian Science Monitor reported that "none of this is happening at a scale to make a real difference."

EU restoration rules have made clearing harder in protected areas. Daniel Lacalle, chief economist at Madrid-based investment firm Tressis, said: "Policies of nature restoration and building have made it hard in some cases to clear the brush that piles up." The European Agroforestry Federation criticized the EU Nature Restoration Regulation for using deadwood as a biodiversity indicator — calling it "inappropriate for forests of medium or high fire-risk" because deadwood is exactly the fuel that drives catastrophic burns. Inside France, France 24 documented a direct standoff: firefighters want brushwood cleared; forest rangers say cutting protected habitat is off-limits.

The EU's own institutions are now split. The EU Council formally endorsed prescribed burning in June 2026, calling on member states to review their permitting rules. But the EU Commission's flagship March 2026 wildfire strategy — issued months before this summer — spent its resources on suppression: 12 additional firefighting planes, 5 helicopters. It included no specific fuel-management provisions. The mechanism it funded is now, by the Commission's own admission, out of capacity.

Where This Lands

Spain's firefighting costs could reach up to €3.275 billion this year, a fourth heatwave is arriving today, and the fires are still burning. Sanchez is pursuing a national climate pact. France is pursuing criminal prosecutions. Scientists and land managers are calling for prescribed burns that EU restoration rules currently complicate in protected areas. The EU Council endorsed those burns in June; the EU Commission's wildfire strategy didn't fund them. None of these tracks are waiting for the others. By the time this season ends, each side will argue its diagnosis was the one that mattered.
