A town-flattening hurricane in Florida. Catastrophic flooding in eastern Kentucky. Crippling heatwaves in the Northeast and West. A historic megadrought. The United States endured 18 separate disasters in 2022 whose damages exceeded $1 billion, with the total coming to $165 billion, according to a new report from the National Oceanic and Atmospheric Administration (NOAA).
The annual report from the nation's premier meteorological institution highlights a troubling trend: Extreme weather events, fueled by human-caused climate change, are occurring at a higher frequency with an increased cost — in dollars and lives.
"Climate change is creating more and more intense, extreme events that cause significant damage and often sets off cascading hazards like intense drought, followed by devastating wildfires, followed by dangerous flooding and mudslides," said Dr. Rick Spinrad, NOAA's administrator, citing the flooding and landslides currently happening in California.
In five of the last six years, costs from climate and weather-related disasters have exceeded $100 billion annually. The average number of billion-dollar disasters has surged over that time, too, driven by a combination of increased exposure of people living in and moving to hazardous areas, vulnerability due to increasing hazards like wind speed and fire intensity, and a warming climate, the NOAA report said.
Climate-fueled hurricanes, in particular, are driving up damages. Hurricane Ian, which killed at least 150 people and pancaked entire neighborhoods when it made landfall in Florida as a Category 4 hurricane, cost $112.9 billion alone.
"There are, unfortunately, several trends that are not going in the right direction for us," said Adam Smith, an applied climatologist at NOAA. "For example, the United States has been impacted by a landfalling Category 4 or 5 hurricane in five out of the last six years."
Other worrying trends are clear too
The rise in frequency and intensity of extreme weather events mirrors a rise in global temperatures. The last eight years have been the warmest in modern history, European researchers said on Tuesday. Average global temperatures have increased 1.2 degrees Celsius (2.1 degrees Fahrenheit) since the Industrial Revolution, when humans started the widespread burning of fossil fuels to power economies and development.
Despite international pledges to cut climate-warming emissions and to move the world's economy to cleaner energy sources, global greenhouse gas emissions continue to rise. A report by the nonpartisan research firm Rhodium Group found that greenhouse gas emissions in the U.S. rose 1.3% in 2022. It was the second consecutive year emissions in the U.S. rose, after a pandemic-driven dip in 2020, despite the Biden administration's goal of cutting U.S. emissions in half by the year 2030.
