Forests Under Siege
A landmark study published in the journal Science has delivered the most comprehensive assessment to date of how climate change will reshape European forests over the coming decades. The research, which synthesized data from thousands of forest plots across the continent and ran projections through multiple climate scenarios, concludes that forest disturbances — including fires, insect outbreaks, and storm damage — will increase dramatically throughout the twenty-first century, with some regions facing two to three times their current disturbance rates by 2100.
The findings have significant implications for European climate policy, timber industries, biodiversity conservation, and the continent's ability to use forests as carbon sinks. Forests currently absorb roughly ten percent of Europe's annual carbon dioxide emissions, but that absorption capacity is threatened if disturbances outpace forest regrowth.
Fire Leads the Threat
Wildfire represents the most dramatic projected increase among all disturbance types. Southern European countries that already experience significant fire seasons — including Spain, Portugal, Greece, and southern France — face particularly severe intensification. But the study also projects a northward expansion of fire risk into regions that have historically been too cool and wet to support large wildfires. Scandinavia, the Baltic states, and central European countries could see meaningful fire activity by mid-century under higher-emission scenarios.
The mechanism is straightforward. Rising temperatures and shifting precipitation patterns create drier conditions during summer months, extending the fire season and increasing the flammability of forest fuels. Warmer winters also reduce snowpack duration, meaning forests dry out earlier in spring and remain fire-prone for a longer portion of the year.
