is not to blame for last year’s extreme drought that crippled the central Great Plains. The study conducted by the National Oceanic and Atmospheric Drought Task
Force places the blame on natural variations in weather patterns that
caused the “flash drought.”“This is one of those events that comes along once every couple hundreds of years,” lead author Martin Hoerling, a research meteorologist at NOAA, said. “Climate change
was not a significant part, if any, of the event.”Other scientists have linked recent changes in the jet stream to shrinking Arctic sea ice, but Hoerling and study co-author Richard Seager of Columbia University said those global warming connections are not valid.
Hoerling used computer
simulations to see if he could replicate the drought using man-made
global warming conditions. He couldn’t. So that means it was a random
event, he said.Keep reading...
