Climate disasters are experienced all over the world; the United States in particular has seen some incredibly damaging and dangerous storms, floods, wildfires, droughts, and heat waves over the past 39 years. Many of these disasters have had lasting effects, especially for those living in the affected regions, and have caused billions of dollars in damage. In just the past year, the United States saw 11 weather and climate events that resulted in 105 deaths and cost more than $1 billion dollars each.
Stacker has ranked the most expensive climate disasters by the billions since 1980 by total cost of all damages, adjusted for inflation. Data were used from the National Centers for Environmental Information (NCEI) and the National Oceanic and Atmospheric Administration (NOAA). Some more recent disasters, such as the California wildfires last June, are not part of the list, as the data and losses are still being compiled and assessed.
Read on to learn of 50 of the most expensive climate disasters in recent decades in the U.S.

More than 100 people were injured and seven were killed. The storm destroyed more than 1,500 homes and caused major damage to 5,000 dwellings.

Wilma—with its maximum sustained 120 mph winds and heavy rains—resulted in heavy flooding as it hurried across the state touching on the Miami/Fort Lauderdale region and exited to the coast again the same day. At least 10 people were killed and 6 million lost power—the most in Florida history.

The 1980 U.S. drought and heatwave covered a 42-day streak of 100-plus-degree days, making it the longest-lasting in the central-eastern region's history. The drought of 1980 tied or met 29 daily high temperature records and hit many other records. It also caused significant damage to agriculture, and led to at least 1,200 deaths. Another remarkable thing about the 1980 drought was the media coverage, which became obsessive. As the U.S. media ran out of coverage ideas while the drought and heatwave dragged on for months, media crews from all over the world stepped on the scene.

More than 17 million acres across nine states were drowned in water. Hundreds of levees broke along the Mississippi and Missouri rivers, killing 48 people and destroying more than 50,000 homes. The flooding had significant impacts on agriculture and infrastructure but also halted all railroad traffic across the Midwest. In addition, 10 commercial airports flooded, and some places along the Mississippi River remained flooded for six months.

Category 4 Hurricane Irma hit the Florida Keys destroying or damaging more than 80% of its buildings. As Irma moved along the coast, the 185 mph winds, tornadoes, and storm surges hit nine states. Florida and South Carolina were the most affected. Jacksonville and Charleston had historic levels of storm surge, which caused severe coastal flooding that left millions without electricity. Irma is both the strongest hurricane documented outside of the Gulf of Mexico and the Caribbean Sea and the longest-lasting, with sustained 185 mph winds over 37 hours.

Hurricane Sandy—“Superstorm Sandy”—struck at the end of October 2012, directly affecting 24 states and all of the U.S. eastern seaboard, wreaking havoc from flash flooding and storm surges to blizzard-like conditions. Sandy resulted in 159 deaths and is the fourth-costliest U.S. storm, causing more than $72 billion in damage. The New York Stock Exchange was forced to close for two consecutive business days for the first time since 1888, and a 14-foot surge caused Manhattan's subway system to sustain its worst damage in 108 years because tunnels were flooded. More than 8.5 million people lost power, and more than 20,000 flights were canceled.

In September 2017, Category 4 Hurricane Maria affected many parts of the United States, but the impact was felt the most in Puerto Rico. After claiming the lives of at least 2,981 people and resulting in more than $90 billion in damage, Hurricane Maria became one of the deadliest and costliest climate disasters in U.S. history. The mass flooding and mudslides in Puerto Rico devastated the country's economy, infrastructure, and living conditions. The hurricane also was one of most rapidly intensifying storms, going from a tropical depression to a Category 5 Hurricane in less than 54 hours.

At the end of August 2017, Category 4 Hurricane Harvey made landfall near Rockport, Texas, spawning more than 30 tornadoes and heavy winds, and dumping 30 to 50 inches of rain on 13 million people in Texas, Louisiana, Mississippi, Tennessee, and Kentucky. In Houston—the nation's fourth-largest city, at least 3,900 people still had no power almost three weeks after the storm, and national gas prices rose as 25% of oil and gas production was shut down in the region. At one point, 75% of Harris County, which encompasses Houston, was under 1.5 feet of water. Massive flooding displaced over 30,000 people and damaged or destroyed over 200,000 homes and businesses.

On Aug. 29, 2005, Hurricane Katrina—the costliest and one of the most-deadly disasters in U.S. history—made landfall near Grand Isle, La., as a Category 3 storm with 127 mph winds and severe storm surges, some in excess of 30 feet. Katrina affected 90,000 square U.S. miles and at least eight states, with most of the damage occurring in Mississippi, Alabama, and Louisiana—particularly New Orleans. At least 50 levees failed in New Orleans resulting in devastating mass flooding. By the end, 1,833 people had been killed, including 1,577 in Louisiana, and more than one million people had been displaced. Two of the region's biggest industries—oil and gas—suffered greatly and tourism to the coastal communities died as infrastructure continued to erode. From April 2000 to July 2006, New Orleans' population decreased by more than half.
