January 2025 Breaks Record as Warmest Month Ever Measured Globally

Global temperatures in January 2025 were 1.75°C above pre-industrial levels, defying expectations of cooling from La Niña conditions.

The EU's Copernicus Climate Change Service reported that January 2025 was the warmest globally recorded, with an average temperature of 13.23°C.
This temperature was 1.75°C above the pre-industrial average, continuing a trend of record-breaking heat over the past two years.
Scientists were surprised by the record, as La Niña conditions—typically associated with cooling—were expected to lower global temperatures.
Europe experienced above-average rainfall in many regions, leading to localized flooding, while global sea surface temperatures remained unusually high.
The 1.5°C threshold of the Paris Agreement has now been exceeded for 18 of the last 19 months, though this does not yet constitute a permanent breach of the target.
