GAO’s reports and testimonies give Congress, federal agencies, and the public timely, fact-based, non-partisan information that can improve government operations and save taxpayers billions of dollars.
Extreme weather related to climate change potentially threatens utilities that produce drinking water and treat wastewater.

There were 14 separate billion-dollar weather and climate disaster events in the U.S. in 2018—with a total cost of at least $91 billion. These costs will likely rise as the climate changes, researchers say.
What GAO Found Since GAO's 2007 report on flood and crop insurance, exposure growth in hazard-prone areas has increased losses, and climate change and related increases in extreme weather events may further increase such losses in coming decades.
What GAO Found The federal government has opportunities to limit its exposure and increase the nation's resilience to extreme weather events. Since 1980, the U.S. has experienced 151 weather disasters with damages exceeding 1 billion dollars each.
