The Copernicus Climate Change Service (C3S) has released the 2025 Global Climate Highlights report, summarising the key trends in global and regional climates for the year.

2025 was the third warmest year on record globally, following 2023 and 2024. Average global temperatures over the 2023–2025 period exceeded 1.5°C above pre-industrial levels (1850–1900), marking the first time a consecutive three-year span has surpassed this level. 

2025 was the third-warmest year on record for Europe, with an average temperature of 10.41°C, 1.17°C above the average for the 1991-2020 reference period.

This data visualisation, produced using data from C3S, shows surface air temperature anomalies and extremes in 2025. It highlights that the Northern Hemisphere experienced warmer temperatures than average.
