Blue tarps cover houses with damaged roofs in Lake Charles, La., after Hurricane Delta hit the city in October 2020.
Federal scientists have confirmed that 2020 basically tied with 2016 for the hottest year recorded since 1880. The Earth is about 2 degrees Fahrenheit warmer today than it was in the mid-20th century. Scientists warn that humans must keep global temperatures from rising more than about 3 degrees Fahrenheit in order to avoid the most catastrophic effects of climate change.
NASA and NOAA calculate global temperatures using slightly different analyses methods, partly in order to check each other s work. Because 2020 and 2016 were so close in temperature, the two analyses led to different rankings: NASA ranks 2020 as the hottest year on record by a tiny margin, while NOAA ranks it as the second hottest year by an equally tiny margin.

Federal scientists have confirmed that 2020 basically tied with 2016 for the hottest year recorded since 1880. The Earth is about 2 degrees Fahrenheit warmer today than it was in the mid-20th century. Scientists warn that humans must keep global temperatures from rising more than about 3 degrees Fahrenheit in order to avoid the most catastrophic effects of climate change.

By most accounts, 2020 has been a rough year for the planet. It was the warmest year on record, just barely exceeding the record set in 2016 by less than a tenth of a degree according to NASA’s analysis.
Massive wildfires scorched Australia, Siberia, and the United States’ west coast – and many of the fires were still burning during the busiest Atlantic hurricane season on record.
“This year has been a very striking example of what it’s like to live under some of the most severe effects of climate change that we’ve been predicting,” says Lesley Ott, a research meteorologist at NASA’s Goddard Space Flight Centre.
