Europe's Wildfire Crisis Demands Climate Action and Fire Prevention Investment

Europe is burning in ways that would have seemed impossible a generation ago. This summer, wildfires have consumed more than 6,000 square kilometers of forest across Spain, France, Portugal, Greece, Italy, and even the cooler reaches of the UK, Ireland, and Norway. By early August, the bill had reached €15 billion. Hundreds of thousands of people have been forced to abandon their homes. The heat is relentless. The drought is deep. And scientists studying the pattern say what we are seeing now is only a preview of what's coming.

Researchers at the Potsdam Institute for Climate Impact Research published a study this week in Global Change Biology that lays out the mathematics of the crisis ahead. Even if the world makes a serious commitment to cutting emissions—even if we meet the climate targets we've promised—39 percent more land will be burning annually by the end of this century than burns today. If we continue on our current path, if global temperatures rise by 3.6 degrees Celsius, the burned area could triple. The Mediterranean will be hit hardest, but western and central Europe, regions that have historically seen few large fires, will also face a transformation. Maik Billing, the study's lead author, put it plainly: wildfires will become much more frequent, especially in places that have not prepared for them.

The international community agreed years ago to limit warming to 1.5 degrees Celsius, or at least to well below 2 degrees. We are nowhere close to meeting that target. And the consequences are already visible. By early August this year, twice as much land had burned across Europe as in recent years during the same period. The heat and drought have created conditions that turn forests into kindling.

But Europe is not helpless. Thomas Hickler of the Senckenberg Society for Nature Research, who contributed to the study, argues that investment in fire prevention, better training and equipment for emergency responders, and stronger coordination between forestry authorities and fire services can make a substantial difference. The European Union has committed around €2.1 billion to forest and wildfire management programs between 2021 and 2027. According to World Bank analysis, that money works: every euro spent on prevention saves up to seven euros on firefighting and reconstruction. If emissions fall rapidly and climate action accelerates, effective fire management could reduce future burned areas by as much as 90 percent.

Yet there is a limit to what management alone can achieve. Kirsten Thonicke, another co-author of the study, warns that climate change could create conditions so extreme that we eventually exceed what is technically possible to prevent and fight. The window for action is narrowing.

Meanwhile, in the High Fens, a wetland and forest region straddling the border between Germany and Belgium, around 3,000 hectares have burned in recent days—the largest wildfire Belgium has recorded in decades. This is significant because wetlands should not burn. Marshes and raised bogs are wet by definition. But when drought drains them, the peat soil beneath—formed from thousands of years of accumulated dead plant material—becomes fuel. Peat fires smoulder underground at low temperatures, producing enormous amounts of smoke but few visible flames. They are extraordinarily difficult to extinguish and can burn for months, sometimes continuing through winter.

When peat burns, carbon stored in the soil for millennia is released in weeks. Wetlands cover only about 3 percent of Earth's surface, yet they hold roughly 30 percent of all carbon in soils worldwide. A peat fire in Indonesia in 1997 burned across roughly 100,000 square kilometers and may have released between 13 and 40 percent of the world's total emissions that year. More than 200,000 people across Indonesia and neighboring countries were hospitalized for acute health problems. The disaster was severe enough that several Southeast Asian nations later adopted an agreement to combat transboundary air pollution.

For Europe, the message from the new research is unambiguous: improved wildfire management will help, but it cannot solve the problem alone. If global temperatures continue to rise as scientists predict, the continent faces a future in which fire becomes not an occasional catastrophe but a defining feature of summer. The choice is between rapid, sharp cuts to emissions now, or accepting a landscape transformed by flame.
