Europe's Hottest Year: Wildfires, Seas Boil
29 Apr
Summary
- 95% of Europe saw above-average temperatures in 2025.
- Wildfires consumed over 1 million hectares, a new record.
- Annual sea surface temperatures reached an unprecedented high.
In 2025, Europe witnessed unprecedented heat, with at least 95% of the continent experiencing temperatures above average. This intense heat contributed to a record-breaking wildfire season, burning more than 1 million hectares, an area larger than Cyprus.
Overall sea surface temperatures in the region reached a yearly record high, and 86% of Europe endured significant marine heatwaves. These conditions underscore the immediate reality of climate change, emphasizing the need for more urgent action.
The continent, which is warming faster than any other globally, also faced drought. Over half of Europe experienced dry conditions in May 2025, making it one of the three driest years for soil moisture since 1992.
Cold regions also felt the heat, with sub-Arctic areas like Norway, Sweden, and Finland experiencing their most severe heatwave on record in July. Temperatures within the Arctic Circle exceeded 30 degrees Celsius, and Iceland recorded its second-largest glacier loss since data collection began.
