WASHINGTON — The powerful tornadoes and other extreme weather events that have cut swaths of destruction across the United States over the past month have prompted many to wonder if they are part of a new trend. Are these violent storms the result of climate change, or can they be explained as normal weather variations?
This has been a record year for tornadoes in the United States. North America seems to be especially hard hit.
“We have probably the most tornadoes when you think about the square mileage where we get them,” says David Imy, operations chief at the National Oceanic and Atmospheric Administration’s Storm Prediction Center, “and also the more intense tornadoes and the reasoning happens to be the Rocky Mountains.”
