NOAA Scientists: 2020 Was Earth’s 2nd-Hottest Year on Record, Just Behind 2016

It’s official: 2020 ranks because the second-hottest 12 months on report for the planet, knocking 2019 down to 3rd hottest, in line with an evaluation by NOAA scientists.

The typical land and ocean floor temperature throughout the globe in 2020 was 1.76 levels F (0.98 of a level C) above common — simply 0.04 of a level F (0.02 of a level C) cooler than the 2016 report.

The Northern Hemisphere noticed its hottest 12 months on report at 2.30 levels F (1.28 levels C) above the Twentieth-century common.

The world’s seven-warmest years have all occurred since 2014, with 10 of the warmest years occurring since 2005.

It was additionally Earth’s forty fourth consecutive 12 months with world land and ocean temperatures, at the very least nominally, above the Twentieth-century common, in line with scientists at NOAA’s Nationwide Facilities for Environmental Info.

scientists, who performed a separate however related evaluation, have decided that 2020 ties 2016 because the warmest 12 months on report, sharing the first-place spot. 

Scientists from even have 2020 tying with 2016 because the warmest 12 months on report, whereas the  ranked 2020 because the second-warmest 12 months on report.

The 2020 common annual Arctic sea ice extent (protection) was roughly 3.93 million sq. miles and ties 2016 for the smallest on report. The 5 smallest Arctic annual extents have occurred within the final 5 years (2016-20).

The annual Antarctic sea ice extent was close to common at 4.44 million sq. miles.
