Overview
- A joint World Meteorological Organization and Copernicus report finds Europe warming at roughly twice the global average, cementing its status as the fastest-warming continent.
- At least 95% of the region logged above-average temperatures in 2025, including a record three-week sub‑Arctic heatwave with temperatures near and within the Arctic Circle above 30°C.
- European seas were the hottest on record in 2025, with 86% of regional waters in strong marine heatwave conditions that damaged sensitive habitats such as Mediterranean seagrass meadows.
- Wildfires burned more than one million hectares and river flows stayed below average for 11 months, straining water supplies, harming agriculture, and exposing people to smoke and heat risk.
- Renewables supplied nearly half of Europe’s electricity in 2025 and greenhouse gas emissions fell well below 1990 levels, even as policymakers push to strengthen climate resilience.
