2015 was second-hottest year on record in the US
The United States saw its second-hottest year on record in 2015, federal scientists announced on Thursday.
The annual average temperature in 2015 in the U.S. was 54.4 degrees Fahrenheit, or 2.4 degrees above the 20th century average, the National Oceanic and Atmospheric Administration (NOAA) announced Thursday.
Since record-keeping began in 1895, only 2012 was a warmer year in the United States. The past 19 years have all been above the 20th century average, NOAA said.
The announcement came after a record-breaking December. Last month was 6 degrees above the 20th century average, NOAA said, smashing a record set in 1939.
The record heat in the U.S. comes as NOAA and its international counterparts are expected to name 2015 the hottest year on record around the world.
Though that announcement has yet to be made, it has long been expected that the year will top the charts internationally. In December, NOAA said the average surface temperature that month would need to be 1.46 degrees Celsius below average in order to avoid topping the charts.
Last year was also the third-wettest on record, NOAA said. December was both record hot and wet, the first time that has happened in a single month in 121 years of record keeping.
The year featured 10 severe weather disasters that caused at least $1 billion in damage. Those events covered five separate disaster types — wildfires, floods, winter storms, drought and severe weather — when most other years feature only three or four, officials said.
Thursday’s report also comes as environmentalists and policy-makers renew their focus on climate change and begin aggressively pushing policies to keep the Earth from warming by more than 2 degrees Celsius this century, a figure scientists warn will bring about the worst of global warming.
