No, no single weather event can be definitively linked to global warming, statistically. But everyone knows what global warming has been predicted to cause, and everyone can see it’s happening. More from Think Progress:
CoreLogic “estimates flood losses in the U.S. this year at approximately $10.67 billion, based on various flooding and storm events recorded in the National Climate Data Center.” The extreme flooding was caused by the most extreme hydrologic conditions in the United States in history — most of the nation was in either extreme deluge or extreme drought. Global warming pollution has driven up temperatures, atmospheric water vapor, and storm intensity, creating a perfect storm of catastrophic floods across the United States.
