The continental United States experienced one of its warmest and wettest years in history in 2015, the National Oceanic and Atmospheric Administration (NOAA) announced Thursday.
Temperatures and precipitation totals were well above long-term averages, according to the year-end report published by the NOAA’s National Centers for Climate Information, and the final numbers indicated the nation had its second-warmest and third-wettest year on record.
The nation also was hit by five different types of weather and climate disasters — flooding, droughts, wildfires, extreme cold and severe storms — a variety the NOAA said is not usually seen. There were 10 disasters in total, and each of them caused at least $1 billion in losses.
The NOAA reported the average temperature in the United States last year was 54.4 degrees Fahrenheit, 2.4 degrees above the nation’s 20th-century average, but .88 degrees lower than the record-setting year of 2012. The average precipitation total in the lower 48 states was 34.47 inches, 4.53 inches above the average level, and the influx of rainfall helped reduce the national drought footprint by about 10 percent. The only wetter years on record are 1973 and 1983.
Every single one of the lower 48 states posted above-average yearly temperatures, the NOAA said, and Washington, Florida and Oregon all posted their warmest years on record. The same can be said of southeastern Louisiana and western Montana.
The temperature and precipitation records date to 1895.
The NOAA also said 10 weather and climate disasters occurred across the nation last year, including wildfires and droughts in the west, flooding in South Carolina, Texas and the midwest, a cold wave in the northeast, tornadoes in Oklahoma and Texas, and severe thunderstorms across the Great Plains. Together, the NOAA said the disasters killed 155 people nationwide.
It’s not common, but also not unheard of, for the United States to see that many different kinds of disasters causing $1 billion in losses in a year. According to the NOAA, the nation usually sees three or four kinds of disasters every year, but five have occurred five other times since 1989.
The overall total of 10 billion-dollar disasters was slightly below the nation’s five-year average of 10.8, the report indicates, but it was still nearly double the 35-year average of 5.2.
The NOAA added the United States has now been the victim of 188 billion-dollar weather and climate disasters since 1980, and they have cumulatively caused more than $1 trillion in losses.
