Weather Whiplash: As Polar Vortex Brings Deep Freeze, is Extreme Weather Linked to Climate Change?
Record cold temperatures are being recorded across the Midwest and eastern United States again today as a so-called polar vortex of dense, frigid air has descended as far south as Texas and Florida. According to the National Weather Service, temperatures are 20 to 40 degrees Fahrenheit below average in parts of Montana, North and South Dakota, Minnesota, Iowa, Wisconsin, Michigan and Nebraska. In Brimson, Minnesota, the temperature fell to minus 40 degrees Fahrenheit. Fargo, North Dakota, recorded temperatures as low as 32 degrees below zero. In Illinois, motorists are being urged to stay off the roads for a second day and schools remain closed in Chicago and other cities. In New York, the temperature dropped by nearly 50 degrees over a few hours on Monday. We are joined by Jeff Masters, director of meteorology at the Weather Underground.
