French firefighters battled a wildfire of "exceptional scale" in the Fontainebleau forest south-east of Paris on Monday as a heatwave gripped much of Europe, forcing the evacuation of 900 homes and exposing the vulnerability of critical infrastructure to climate-driven extreme weather. The blaze had raced across about 800 hectares in the forest about 40 miles from the French capital, while the latest French heatwave forced the temporary shutdown of three nuclear power stations to avoid the discharge of warm cooling water into overheated waterways.
Interior Minister Laurent Nunez said the fire may have been deliberately set, with about 10 fire ignition points within a perimeter of 1,000 meters suggesting it could have been started intentionally. No home had yet been burned and no one had been injured, he said. An investigation was under way to determine the cause of the fire. The mayor of Fontainebleau, Julien Gondard, said, "This exceptional area is consumed by flames, we've never seen anything like this." He added, "The forest is fragile and it's in a critical condition."
Climate Crisis Reaches the Capital
Fire officials said it could take several days to several weeks to fully contain the fire, which they described as "very virulent" and of "exceptional scale." Pierre Ory, the prefect of Seine et Marne department, said by Monday afternoon it had not been contained and "continued to progress moderately." The Paris region remained under the highest heatwave alert. Eric Brocardi, of France's national federation of firefighters, said it was the first time firefighting planes had been sent up from the normally drier and hotter south of the country to extinguish fires in the Paris region. He said, "The aim is to save lives and property." Two firefighting helicopters and an observation aircraft were also helping to tackle the blaze.
About 400 firefighters were working to contain the fire, which erupted two days before the 14 July Bastille Day national holiday. Half of the 700 residents of the village of Le Vaudoué were evacuated, and firefighters were operating in several other towns in the area. Olivier Compta, who was overseeing the firefighting operation, said that without the use of firefighting planes, other villages would already have been evacuated.
Transport Disruption and Economic Impact
The fire began late on Sunday afternoon and blocked the A6 highway linking Paris with Lyon and the south. It also disrupted high-speed train services, with SNCF saying there were delays of up to eight hours for trains arriving at or leaving from Gare de Lyon in Paris. On Monday morning, rail services were returning to normal. Earlier, a fire had also blocked a highway running east from Paris and disrupted a high-speed train line to the south of France.
French authorities said an estimated 32,000 hectares of land, roughly the size of Orlando, Florida, had burned so far this year, more than in the whole of 2025. Julien Marion, director general of civil security in France, said on Friday that since the start of this year wildfires had covered some 25,000 hectares of land in France. Organisers of the Tour de France shortened Sunday's stage by 30 kilometers as temperatures neared 40C.
Europe's Warming Crisis
The Paris region, along with large parts of the rest of France, has had a succession of heatwaves since May, and temperature records have been broken in several other countries across Europe. Scientists said climate change is driving up temperatures around the world, Europe is the fastest warming continent, and the heatwaves are causing increased summer heatwaves, greater pressure on Europe's water supply and more intense wildfires. The record-breaking temperatures across Europe this summer have led to major wildfires, most notably in Spain, where at least 13 people were killed by Thursday's wildfire in Almeria, one of the country's deadliest ever. In the UK, a large wildfire in north Wales was declared a major incident by emergency services on Sunday, as firefighters tackled fires across England and Wales.
Why This Matters:
The Fontainebleau wildfire brings the climate crisis to France's doorstep in unprecedented fashion — firefighting planes deployed in the Paris region for the first time, nuclear reactors shut down because rivers are too warm to cool them, and 32,000 hectares burned in seven months. This isn't a southern European problem anymore. It's a systemic threat to infrastructure, public health, and economic stability across the continent. The temporary shutdown of three nuclear power stations during a heatwave exposes the fragility of energy systems designed for a climate that no longer exists. Scientists warn that Europe is the fastest warming continent, and the succession of heatwaves since May confirms what climate models have long predicted: more intense, more frequent, more deadly summers. Without massive public investment in climate adaptation — firebreaks, water management, grid resilience, and emergency services — these crises will only multiply. The EU's Green Deal must accelerate, and member states must fund the infrastructure and personnel needed to protect communities from a warming world.
