Those unusual frozen Februaries in Texas may not be so unusual anymore.
Early winter has been warming across North America, but late winter is another story. Scientists have documented a cooling trend over more than 40 Februaries, marked by dangerous and increasingly common intrusions of Arctic air deep into the United States.
“December has certainly been warming if you look at the U.S.,” Judah Cohen, a climatologist at the Massachusetts Institute of Technology, says in a recent video.

“We tend to get more severe winter weather when the polar vortex is weak and more milder rainy weather when the polar vortex is strong, and we’ve seen a decrease in the strong state of the polar vortex and an increase and the weak state of the polar vortex,” Cohen said in an interview with Peter Sinclair, a videographer for Yale Climate Connections who posts pithy snippets of interviews on his excellent Youtube channel, greenmanbucket.
