Climate & Weather Extremes: Attribution and Risk
Channel: NSF NCAR & UCAR Science Education
Date: 04/07/2016

NCAR Distinguished Senior Scientist Kevin Trenberth shares the science of attribution, especially in terms of weather extremes, and notes that scientists strive for 95% confidence level, which is a high burden of proof. Today, he believes, that climate change impacts all weather-related extremes to a certain degree, especially those involving water or lack thereof, and certainly temperature extremes. The question is not "if" but rather "to what degree."
