Last year will be remembered as the "costliest" one for the United States with losses from hurricanes, fires and freezes reaching a record US$306 billion, a U.S. government report said Monday.
The United States had 16 weather and climate disasters in 2017 each with losses exceeding US$1 billion, the U.S. National Oceanic and Atmospheric Administration said in its report.
That ties 2011 for the record number of billion-dollar disasters for an entire calendar year, but the total cost shatters the previous U.S. annual record of US$214.8 billion in 2005, the agency said.
At least 362 people died and many more were injured during the course of the disasters that included one drought event, two flooding events, one freeze event, eight severe storm events, three tropical cyclone events, and one wildfire event, it said.
Among the disasters are the western U.S. wildfires that caused damages tallying US$18 billion, which was triple the previous U.S. record, said the report.
Losses from Hurricane Harvey, which caused massive flooding in Texas, exceeded US$125 billion, which ranked second only to Hurricane Katrina, the costliest storm in the 38-year period of record.
Hurricanes Maria and Irma had total damages of US$90 billion and US$50 billion, respectively.
Hurricane Maria now ranks as third costliest weather and climate disaster on record for the nation, with Irma coming in close behind as fifth costliest, it said.
"Since 1980, the U.S. has sustained 219 weather and climate disasters that have exceeded US$1.5 trillion in overall damages to date," the U.S. agency wrote.
"The 1980-2017 annual average is 5.8 events; the annual average for the most recent five years (2013-2017) is 11.6 events."
The U.S. agency also said that the average U.S. temperature in 2017 was 54.6 degrees Fahrenheit (12.6 degrees Celsius), 2.6 degrees Fahrenheit above the 20th century average.
"This was the third warmest year since record keeping began in 1895, behind 2012 (55.3 degrees Fahrenheit) and 2016 (54.9 degrees Fahrenheit), and the 21st consecutive warmer-than-average year for the U.S. (1997 through 2017)," the report said.
In fact, the five warmest years on record for the contiguous U.S. have all occurred since 2006, it noted, reflecting a long-term warming trend.
