Sims that took a year to run show US current path risks five-fold jump in extreme rainfall, intensity increases of 70%, so a storm dropping 5 cm of water today would likely dump 9 cm by 2100

“Think about the most intense thunderstorm last summer. In the future climate in some places in the United States, you’ll get as many as five of those [each summer],” says lead study author Andreas Prein, a scientist at the National Center for Atmospheric Research in Boulder, Colorado.
