January 2025 Breaks Record as Hottest Month Globally

Global temperatures reached unprecedented levels despite ongoing La Niña conditions, surprising climate scientists.

January 2025 recorded global temperatures 1.75°C above pre-industrial levels, surpassing the previous record set in January 2024.
This record-breaking heat occurred during a La Niña phase, which typically cools global temperatures, defying expectations.
Scientists are investigating potential factors behind the anomaly, including recent volcanic activity and changes in marine shipping fuels.
The start of 2025 contrasts with predictions that global temperatures would cool after the strong El Niño event of 2023-2024.
Weather models suggest global temperatures may drop in February due to predicted cooling in the Northern Hemisphere.
