What does the Global Change Biology study led by the Potsdam Institute for Climate Impact Research project about how Europe’s annual wildfire area could change by 2070–2100 under low- and high-emissions scenarios, how climate-driven heat, drought, and wind would affect regions su

What the current crisis shows: By 19 August 2026, fires had burned 616,202 hectares in Europe—more than double the 2006–25 average for the same point in the year, although below the exceptional 2025 level. The preceding 2025 EU fire season was the worst on record, with 1,079,538 hectares burned.

Economic stakes: Estimates for the summer 2026 fires had already exceeded €15 billion in economic costs by early August; figures vary by methodology and scope, so these should be treated as preliminary rather than a final accounting. The European Commission estimates property and infrastructure damage from wildfires at roughly €2.5 billion annually in the EU even before wider losses to health, ecosystems, farming, forests and tourism are counted.

What investment can do: Prevention—such as managing vegetation and fuels, restoring fire-resilient landscapes, defensible space around settlements, and public risk education—can reduce the likelihood that ignitions become disasters. Earlier detection, warning systems, trained local crews, and adequate ground and aerial firefighting capacity can contain many fires faster, limiting burned area and therefore avoiding much larger rebuilding and recovery bills. The EU explicitly promotes integrated wildfire-risk management and sustainable fuel management.

Why management alone is not enough: In the most extreme heat–drought–wind combinations, fires can become too fast, intense and widespread for suppression systems designed around historical conditions. That is why the researchers’ conclusion is two-track: strengthen locally tailored preparedness and prevention now, while rapidly cutting greenhouse-gas emissions to prevent the fire-weather escalation that adaptation cannot reliably manage.
