January 2025 Breaks Record as Hottest January in History

January 2025 is now officially the hottest January ever recorded, continuing a trend of rising global temperatures. According to the Copernicus Climate Change Service, the month’s average temperature was 55.8°F, making it 3.1°F warmer than pre-industrial levels. This marks the 18th out of the last 19 months where global temperatures have surpassed the 1.5-degree warming threshold set by the Paris Agreement. What makes this record stand out is that it happened despite La Niña, a weather pattern that typically brings cooler temperatures. Instead, much of the world saw significant warming. Canada, Alaska, Siberia, South America, Africa, and Australia all experienced unusually high temperatures. Meanwhile, parts of the U.S., Russia, and Southeast Asia recorded colder-than-average conditions, showing the complexity of cli
mate patterns. Europe also felt the heat. It was the second warmest January ever recorded there, with southern and eastern Europe seeing temperatures more than 4°F above average. In contrast, regions like Iceland, the U.K., and northern France experienced colder-than-normal weather.

Scientists had expected 2025 to be cooler than last year due to La Niña’s influence, but so far, that hasn’t been the case. The Arctic, in particular, saw extreme temperature spikes, with
some areas hitting 54°F above normal. While these individual records may seem like outliers, experts say they are part of a much bigger trend of increasing global temperatures. In the U.S., January was colder than usual in many places, but that doesn’t mean global warming is slowing
down. A colder month in one region doesn’t change the overall upward trend in global temperatures. Data from the National Centers for Environmental Information shows that January’s global surface temperature was 2.4°F
above the 20th-century average, making it the
warmest January in recorded history. Looking ahead, there is a 7% chance that 2025 could end up being the hottest year ever. While that number may seem small, the fact that it is even a possibility says a lot about global warming.
With record-breaking months becoming
more frequent, climate experts urge for continued research, policy action, and global cooperation to slow the trend. January 2025 is another reminder that climate change is an ongoing issue with real-time impacts around the world.
