Penn State climate scientist Michael Mann said Sunday that, while global warming didn’t cause Hurricane Harvey, it surely “worsened” the effects of the storm through higher sea levels and increased atmospheric moisture.
Mann’s explanation, however, goes against the prevailing evidence of global warming’s measured impacts on storms. Many climate scientists have been careful not to tie individual weather events to manmade warming.
“I’m sure you won’t be surprised to hear people blaming Harvey on global warming,” climate scientist Judith Curry wrote in a recent blog post. “How unusual was Harvey? Well, it will definitely be in the record books for ending the 12 year drought of major hurricanes striking the U.S.”
“Anyone blaming Harvey on global warming doesn’t have a leg to stand on,” Curry wrote.
