Heat waves, wildfires, drought: What lessons can Europe draw from its hottest summer on record?

Europe did not escape the heat wave this summer. August 2026 was the hottest month ever recorded on the continent, and Europe as a whole experienced the worst summer in its history, with temperatures 2.7°C above seasonal norms.

This exceptional heat triggered a record drought, which continues into September in several regions of the continent. At the height of summer, two-thirds of European Union territory were placed on drought alert, a situation that weakened vegetation and agriculture while facilitating the spread of forest fires.

Multiple consequences

The combined effects of heat waves, drought, and wildfires raise questions about the lessons the European Union should learn, as these extreme climate events appear to intensify year after year. European agriculture, already under pressure, was particularly hard hit by prolonged water shortages, with expected repercussions on crop yields.

The persistence of drought in September, following such a grueling summer, fuels concerns about the capacity of European ecosystems and infrastructure to cope with increasingly frequent and intense climate episodes. European authorities will likely need to reassess their adaptation strategies in light of these new records.
