‘Winterless Christmas’ Record-Breaking Heat Sweeps Across the US and Parts of Europe
Large parts of the United States and Europe experienced unusually high temperatures during the Christmas period, prompting climate scientists to describe the phenomenon as a “winter heatwave” and, in some regions, a “winterless Christmas.” The unseasonal warmth has been linked to persistent high-pressure systems in the atmosphere, with climate change amplifying the intensity of these events.
In the days leading up to Christmas, vast areas of the US recorded daytime temperatures as much as 20 degrees Celsius higher than the seasonal average. Regions across the West, Plains, Midwest, South and Southeast were affected, with temperatures running 15 to 25 degrees Fahrenheit above normal, and in some locations soaring 25 to 35 degrees Fahrenheit higher than usual.
