Record-breaking extreme heat and cold events may result from similar underlying mechanisms
The highest temperature ever verifiably recorded on Earth—54.4 degrees Celsius (130 degrees Fahrenheit) in Death Valley, California, on July 9, 2021—comes just months after record-low temperatures were recorded across Asia and the United States. In sweltering heat, the results of a rapidly warming Earth are clear. In a blizzard, it can be more difficult to understand how global warming can cause such freezing cold. An international research team examined three extreme events from the past winter to elucidate the mechanisms underlying such swings in temperature and weather.
