January 2025 was warmest on record as climate change ‘overwhelms’ La Niña’s cooling
January 2025 was the warmest January on record, surpassing the previous record set by January 2024, according to satellite data from the EU’s Copernicus program. The findings were unexpected as ongoing La Niña conditions in the Pacific typically cool down global temperatures.
The global average surface air temperature for the month reached 1.75° Celsius (3.15° F) above pre-industrial levels. The most dramatic variation, up to 6°C (10.8°F), was concentrated in northern Canada, Russia and the Scandinavian countries.
