’Devastation like none of us have ever seen before’

From the connection to climate change to research that helps us understand wind intensity, University of Miami experts address the deadly flurry of tornadoes that hit the central United States over the weekend. Kentucky Gov. Andy Beshear didn't mince words. "It's devastation like none of us have ever seen before,” he said Sunday on CBS News' Face the Nation. Beshear was referring to the destructive flurry of tornadoes that ripped through six states late Friday, killing at least 90 people, knocking out power, and destroying scores of homes and buildings, with the Bluegrass State the hardest hit. In the small town of Mayfield, a twister flattened a candle factory, where more than 100 people were working inside. As of Sunday, 40 individuals had been rescued from the building.
