Climate change could dramatically increase the area of Europe affected by wildfires by the end of this century, with the annual burned area potentially rising by between 39% and 192% compared with current levels, according to a new international study published in Global Change Biology.

The research, led by scientists including Potsdam Institute for Climate Impact Research researcher Mike Billing, examines how rising temperatures and changing weather conditions could alter wildfire activity across Europe.
The researchers warn that increasingly hot, dry and windy conditions are likely to create more favourable conditions for fires, potentially putting forests, ecosystems and biodiversity under growing pressure.
Two Very Different Climate Scenarios
The study examined different levels of global warming.
Under a relatively lower-warming scenario of around 1.8°C, the researchers estimate that the area burned by wildfires across Europe could be approximately 39% higher by the end of the century than it is today.
Under a much higher-warming scenario of around 3.6°C, the increase could reach 192%.
That would mean the annual area affected by wildfire could become almost three times the current level.
The findings underline the significant difference that limiting global warming could make to Europe's future wildfire risk.
Mediterranean and Central Europe Among the Most Exposed
The study indicates that the effects will not be evenly distributed across the continent.
Central Europe, large parts of Western Europe and the Mediterranean region are expected to experience some of the strongest increases in wildfire activity.
The Mediterranean is already highly exposed to heat, drought and prolonged dry periods. Increasing temperatures could intensify these conditions, creating longer periods in which vegetation becomes highly flammable.
But the research also suggests that wildfire risk is no longer exclusively a southern European problem.
As climate conditions change, areas further north and into Central Europe could increasingly experience conditions favourable to large-scale fires.
Climate Is Not the Only Factor
The researchers stress that future wildfire activity will not be determined by climate change alone.
Land-use patterns, vegetation management, fire prevention, early detection and the ability of authorities to respond rapidly can all influence how much land ultimately burns.
This is an important distinction.
A warmer climate can create conditions that make fires more likely to spread, but effective fire management can significantly reduce the final area affected.
Better Fire Management Could Make a Major Difference
One of the study's most important findings concerns the potential impact of prevention and firefighting measures.
According to the research, improved fire management could reduce the projected burned area by as much as 92% under the 1.8°C warming scenario.
Even under the higher 3.6°C warming scenario, better fire management could reduce the projected burned area by approximately 72%.
The finding offers an important message for governments: climate adaptation and wildfire preparedness can substantially influence the eventual consequences of a warming climate.
Why Europe Should Be Concerned
Wildfires are not simply a threat to forests.
Large fires can destroy homes and infrastructure, threaten human lives, damage agricultural land, release large quantities of carbon dioxide and particulate pollution, and disrupt ecosystems.
Repeated severe fires can also change landscapes by destroying vegetation faster than ecosystems can recover.
For biodiversity, the consequences can be particularly serious when fires occur repeatedly in areas already under pressure from drought, habitat loss and other environmental stresses.
A Warning for the Future
The study's projections arrive as global temperatures continue to rise.
The source material notes that United Nations Environment Programme estimates indicate the world is currently heading towards approximately 2.8°C of warming by the end of the century under present trajectories.
If warming remains elevated, the research suggests that Europe could face substantially greater wildfire pressure than today.
But the study also provides a reason for cautious optimism.
The future is not determined by temperature alone.
Reducing emissions can limit climate-driven fire risk, while better land management, early-warning systems, prevention strategies and firefighting capacity can reduce the amount of land ultimately lost to fire.
The Bigger Climate Message
Europe's wildfire challenge is therefore becoming a two-front battle.
The first is slowing climate change by reducing greenhouse-gas emissions.
The second is adapting to the climate that is already changing.
That means investing in early detection, improving forest management, strengthening emergency response systems and ensuring that communities in high-risk areas are prepared before extreme fire conditions arrive.
The research ultimately delivers a clear warning: the hotter Europe becomes, the greater the potential wildfire threat. But the scale of future damage will also depend on how effectively governments prepare today.
