Flood risk

Hurricane Ian, one of the most powerful storms to hit the U.S., tore part of the roof off a hospital in Port Charlotte, Florida, and flooded the building’s lower level emergency room, sending staff scrambling to move patients as water poured in. At least nine hospitals and dozens of nursing homes had to transfer patients after losing access to clean water because of the storm. Health care services are essential at any time, but when disasters strike, those services become even more crucial as injuries rise. Yet in many coastal communities, the hospitals were built in locations that are at increasingly high risk of flooding during hurricanes. I study ways to improve disaster communications, including how health care organizations prepare for severe weather events. Here’s what research shows about the rising risks. High percentage of coastal hospitals at risk Given the impact of climate change, many areas are susceptible to severe weather events and hazards. Healt...

Hundreds of industrial facilities with toxic pollutants are in Hurricane Milton’s path as it heads toward Florida, less than two weeks after Hurricane Helene flooded communities across the Southeast. Milton, expected to make landfall as a major hurricane late on Oct. 9, is bearing down on boat and spa factories along Florida’s west-central coast, along with the rubber, plastics and fiberglass manufacturers that supply them. Many of these facilities use tens of thousands of registered contaminants each year, including toluene, styrene and other chemicals known to have adverse effects on the central nervous system with prolonged exposure. Farther inland, hundreds more manufacturers that use and house hazardous chemicals onsite lie along the Interstate 4 and Interstate 75 corridors and their feeder roads. And many are in the path of the storm’s intense winds and heavy rainfall. Black dots indicate facilities in EPA’s...

Atmospheric rivers – those long, narrow bands of water vapor in the sky that bring heavy rain and storms to the U.S. West Coast and many other regions – are shifting toward higher latitudes, and that’s changing weather patterns around the world. The shift is worsening droughts in some regions, intensifying flooding in others, and putting water resources that many communities rely on at risk. When atmospheric rivers reach far northward into the Arctic, they can also melt sea ice, affecting the global climate. In a new study published in Science Advances, University of California, Santa Barbara, climate scientist Qinghua Ding and I show that atmospheric rivers have shifted about 6 to 10 degrees toward the two poles over the past four decades. Atmospheric rivers on the move Atmospheric rivers aren’t just a U.S West Coast thing. They form in many parts of the world and provide over half of the mean annual runoff in these regions, including the U.S. Southeas...

The trauma of natural disasters doesn’t end when the storm or wildfire is gone, or even when communities are being put back together and homes have been rebuilt. For many people, being displaced by a disaster has long-term consequences that often aren’t obvious or considered in disaster aid decisions. We study public policy and disaster response. To get a better understanding of the ongoing challenges disaster victims face – and how officials can respond more effectively – we analyzed U.S. Census Bureau surveys that ask people nationwide about their disaster displacement experiences, as well as their stress and anxiety. The results show how recovery from disasters such as hurricanes, wildfires, tornadoes and flooding involves more than rebuilding, and how already vulnerable groups are at the greatest risk of harm. Millions are displaced every year The Census Bureau’s Household Pulse Survey has been continually collecting data on people’s so...
