Hurricanes Harvey, Irma and Maria combined with devastating Western wildfires and other natural catastrophes to make 2017 the most expensive year on record for disasters in the United States, the National Oceanic and Atmospheric Administration reported Monday. The disasters caused $306 billion in total damage in 2017, with 16 events that caused more than $1 billion in damage each. The bulk of the damage, at $265 billion, came from hurricanes. In this report on extreme weather, Lab co-director Solomon Hsiang is interviewed about his research on how natural disasters impact societies.“There’s no one in the country who’s completely insulated from these impacts,” he said.
