“The snowstorm that battered the South this weekend, leaving thousands without power, was likely exacerbated by climate change, according to leading climate scientists. It’s a counterintuitive suggestion, because greenhouse gases are trapping heat and causing higher average temperatures. Sometimes winter weather is milder as a result. But in North America, especially the East Coast and the South, colder winds are blowing in with greater frequency because of how Arctic warming is distorting two phenomena: the jet stream, a band of air flowing west to east, and the polar vortex, a wintertime area of cold air near the North Pole.” |
