2025 had the second warmest first quarter (Jan-Mar) on record, just a hair behind last year (2024). This is remarkable since 2024 was boosted by a strong El Nino event, while 2025 started off in weak La Nina conditions.

Winters have been warming rapidly in the contiguous US over the past 50 years. There are now on average 13 fewer days where temperatures get below freezing (0C, 32F), with some places seeing nearly full month that no longer gets below freezing:
Turning off air pollution monitoring at U.S. embassies around the world doesn't compare to depriving Ukrainian civilians of defences against Russia's missiles in cruelty, but it is an astonishingly pointless act of sabotage. U.S. monitoring in Beijing played a central role in…

February 2025 was the third warmest February on record after 2024 and 2016, at 1.59C above preindustrial level. This is the first time a month has not been the warmest or second warmest on record since June 2023.
The mass firing of both new hires and recently promoted senior staff within #NOAA, including mission-critical and life-saving roles at the National Weather Service (#NWS), is profoundly alarming. 1/11
Global surface temperature anomalies have fallen a bit in recent weeks, making it very likely that February will not set a new record after a record January. However, its still on track to be the 3rd warmest at 1.56C above preindustrial levels in ERA5.
