December 2025 around the Arctic featured very large departures from normal in both directions in ERA5 courtesy of ECMWF/Copernicus reanalysis. Much of Alaska and northwest Canada were quite cold, while far eastern Russia and the Svalbard areas were far warmer than average. It didn't balance out though: overall this was the ninth warmest December on record for the Arctic (land and seas north of 60ºN). Brian Brettschneider (npub1z0w…vryl)
