In the first study of its kind, Danielle Touma, with fellow Bren School researcher Samantha Stevenson and colleagues Flavio Lehner of Cornell University and the National Center for Atmospheric Research (NCAR), and Sloan Coats from the University of Hawaii, have quantified competing anthropogenic influences on extreme fire weather risk in the recent past and into the near future. By disentangling the effects of those man-made factors the researchers were able to tease out the roles these activities have had in generating an increasingly fire-friendly climate around the world and the risk of extreme fire weather in decades to come.
