LONDON — A heat wave near the Arctic, a warmer Mediterranean and wildfires and floods across Europe were part of a year of extremes in 2025, further evidence of how human activity is changing the continent’s climate, European scientists said in a report on Wednesday. At least 95% of Europe had above-average annual temperatures in 2025, according to the report. Wildfires burned more than 1 million hectares of land, the most on record.
