As the atmosphere continues to warm, we are seeing more and more billion-dollar weather and climate disasters in the United States. Thru September, there had already been 11 such events in the Lower 48 according to NOAA’s National Centers for Environmental Information. This number will likely rise once the final calculations are completed for Hurricane Michael and the California wildfires. If these two disasters wind up being added, we will have a total of 13 billion-dollar disasters for the year, making it one of the worst years in U.S. history, behind only 2017, 2011 and 2016. For perspective, the average year sees about six billion-dollar disasters.
