Tornadoes, like those which hit Texas and Oklahoma recently, are devastating when they strike. But are they increasing in frequency due to global warming? Well, while there was an uptick in tornado activity in 2010, 2012 and 13 actually saw a dramatic plummet in the number of twisters. In fact, according to Accu-weather, the past year has seen the fewest number of tornadoes since 1954, and the number of tornado fatalities from May 2012 until April 2013 were the fewest in a 12-month period since 1899. So despite recent tornado outbreaks in the Midwest, meteorologists assert that historical weather patterns are normal and there’s no indication tornado activity is twisting out of control.
