Study: Human-Driven Heat Has Sharply Worsened Europe’s 2026 Drought

Overview

• A World Weather Attribution analysis shows human-caused warming made the 2026 European drought far worse by increasing extreme heat and evaporation rather than mainly by lowering rainfall.
• The study quantified large changes versus a roughly 1.4°C cooler climate: agricultural soil drought is about five times more likely in Western Europe and 11 times more likely in Eastern Europe.
• Conditions favorable to evaporation were dramatically more common between January and June, with WWA finding roughly 80 times higher odds in Western Europe and 40 times higher odds in Eastern Europe.
• Copernicus data identify June 2026 as the hottest June in Western Europe, and low river and reservoir levels have already disrupted river navigation, farming and industry while prompting national water restrictions and drought emergency declarations.
• Scientists say the findings link fossil-fuel-driven warming to near-term threats to food, energy and transport systems and strengthen the case for urgent water management and adaptation measures.
