European State of the Climate 2025
Key Messages:
At least 95% of Europe experienced above-average annual temperatures in 2025.
A record three-week #heatwave affected sub-Arctic #Fennoscandia, with temperatures near to and within the Arctic Circle exceeding 30°C.
#Glaciers in all European regions saw a net mass loss, with #Iceland recording its second-largest glacier loss on record; snow cover was 31% below average; the #Greenland Ice Sheet lost 139 gigatonnes (139 billion tonnes) of ice.
The annual sea surface temperature for the European region was the highest on record, and 86% of the region experienced at least ‘strong’ marine heatwaves.
#Wildfires burnt around 1,034,550 hectares, the largest area on record.
#River flows were below average for 11 months of the year across #Europe, with 70% of rivers seeing below-average annual flows.
#Storms and #flooding affected thousands across Europe, though extreme #rainfall and flooding were less widespread than in recent years.
#Renewables supplied nearly half (46.4%) of Europe’s electricity in 2025, with solar power reaching a new contribution record of 12.5%.
#Biodiversity is vital for a sustainable future, but #ClimateChange is a major cause of its degradation. Climate change and biodiversity are strongly connected within European policy and frameworks.
