How warm was Europe in 2025? 🔍 It was the third‑warmest year on record for Europe, with an average temperature of 10.41°C, 1.17°C above the 1991–2020 average and 0.30°C below the record year of 2024. #CopernicusClimate #GCH2025 🔗 climate.copernicus.eu/global-clima... @ecmwf.int

🌡️ WMO confirms 2025 was one of warmest years on record. 2025 was one of the 3 warmest years on record, with the global average surface temperature at 1.44°C ± 0.13°C above the 1850-1900 average, according to WMO’s consolidated analysis of 8 datasets. 🔗 https://bit.ly/49xpkWP

In 2025, the annual average sea surface temperature (SST) outside of the polar regions ranked 3rd‑warmest on record. Monthly extra‑polar SST stayed among the top four throughout 2025, despite the absence of an El Niño event. Details in #GCH2025 ➡️ climate.copernicus.eu/global-clima... @ecmwf.int

Carlo Buontempo, Director of the Copernicus Climate Change Service (C3S) @ECMWF emphasises how the global average temperature exceeded 1.5°C over a three-year period (2023–2025) – the first time in the #ERA5 record – bringing us closer to the Paris Agreement threshold. @ecmwf.int ⬇️

In 2025, global sea ice extent saw a record low: In February, combined Arctic + Antarctic sea ice extents fell to the lowest level in the satellite records. @ecmwf.int ⬇️

🌍🌐 Our first AI DestinE blog of the year looks at a prototype ML sea ice model developed in the framework of the #DestinE initiative, learning from decades of data to predict sea ice and surface-ocean changes. Read more ➡️ destine.ecmwf.int/news/destine...

Which latitudes saw the largest temperature anomalies in 2025? While the tropics contributed less to 2025’s global temperature anomaly than in 2024 and 2023, the Antarctic region recorded its warmest year on record and the Arctic its 2nd warmest. 🔗 climate.copernicus.eu/global-clima... @ecmwf.int

The global warming trend continued in 2025. Each of the past 11 years (2015–2025) has been among the 11 warmest on record. Explore more data from #CopernicusClimate in the Global Climate Highlights 2025. #GCH2025 🔗 climate.copernicus.eu/global-clima... @ecmwf.int

🌡️ 2025 was the third-warmest year on record, with a global average temperature 0.59°C above the 1991–2020 average & 1.47°C above the 1850–1900 pre-industrial level. It was 0.13°C below 2024, the warmest year on record, and only 0.01°C cooler than 2023. @ecmwf.int ⬇️

Today @copernicusecmwf.bsky.social released the Global Climate Highlights report 2025. ECMWF Director-General Florian Pappenberger noted that "it confirms that the world is in the warmest decade on record and that the EU’s investment in Copernicus remains critical”. ➡️ www.ecmwf.int/en/about/med...
