The climate crisis has not only been leaving deadly heatwaves and more destructive hurricanes in its wake, but also probably creating extreme winter weather events, according to a new report released on Thursday by the American Association for the Advancement of Science’s journal Science.
...
Its authors argued that this type of Arctic change actually increased the chances of tightly spinning winds above the North Pole, known as the Arctic stratospheric polar vortex, being stretched and thus boosting the chances of extreme weather events in the US and beyond.

While many, including the White House, attributed the event to climate change, Cohen said he believed this was the only paper that actually showed the connection between the cold wave and Arctic change, and demonstrated the physical mechanism surrounding all of this – the stretched polar vortex.
...
The process for putting together this report involved the authors conducting observational analyses of the stratospheric polar vortex over the past four decades. They also conducted numerical modeling, in which they used some of the same models experts utilized when predicting such weather events as Hurricane Ida.
