2021 was the sixth warmest year on record since 1880, this was announced by US scientists who developed a Map showing the increase in heat on the planet.

Yes OK, 2021 presented a slightly lower temperature than that recorded in 2019 and 2020, whose consecutive years were among the three warmest on record, experts from the National Centers for Environmental Information (NCEI) of the National Office of Oceanic and Atmospheric Administration (NOAA), determined that the year that recently ended ranked sixth on the list of the warmest years on record, and whose data goes back to 1880.

According to specialists, the average temperature of the Earth’s land and ocean surfaces in 2021 was 0.84 degrees °C above the 20th century average.

According to experts, the colored blocks presented on the map express the increase in heat on the planet, with dark blue being the area with the coldest record and dark red being the area with the hottest record.

Independent of the data presented by the Office, scientists from the National Aeronautics and Space Administration (NASA) carried out a similar analysis, in which they determined that 2021 was the sixth warmest year on record, tied with 2018.

While Europe’s Copernicus experts ranked 2021 as the world’s fifth warmest on record.

Facts about the sixth warmest year on the planet

Between the facts highlighted by NOAA scientists also found:

  • 45 consecutive years of high global temperatures

2021 marked the 45th consecutive year since 1977 with global temperatures above the 20th-century average, with the years from 2013 to 2021 being among the ten warmest years on record.

  • high ocean temperature

Northern Hemisphere land and ocean surface temperatures were also the sixth-highest on record, with 1.09 degrees °C above the average.

In the northern hemisphere land areas alone, the 2021 temperature was third warmest on recordbehind 2016 (second warmest) and 2020 (warmest)”NOAA reported in a press release.

  • Ocean Heat Content (OHC)

Ocean heat content (OHC), which describes the amount of heat stored in the upper levels of the ocean, reached a record level in 2021, surpassing the previous record set in 2020.

The seven highest OHC figures have occurred from 2015 to 2021. This ocean heat content can contribute to sea level rise.

Additional Findings Discovered by NOAA

In addition to providing information on the global temperature of the Earth, the NOAA researchers presented a series of additional findings, such as:

According to experts, the average annual sea ice cover in the Arctic was about 10.5 million square kilometers, which means it wase ninth smallest annual average coverage which has been recorded between 1979 and 2021.

In addition, the last seven years, comprising 2015 to 2021, had annual sea ice extent that ranked among the 10 smallest on record, according to data from the National Snow and Ice Data Center.

And in Antarctica, annual sea ice cover was slightly below average at 11.4 million square kilometers, which represents the 18th smallest recorded.

  • global tropical cyclones

There were an above-average number of tropical cyclones around the world in 2021, with a total of 94 named storms. This value ties back to 1994 as the 10th highest number of named storms in the 41-year record.

However, according to specialists, there were only 37 hurricane-force tropical cyclones worldwide, the lowest number on record, just beating the second-lowest record of 38 set in 2009.

  • December 2021 heat

The average December temperature across global land and ocean surfaces was 0.83 degrees C above the 20th-century average. This value tied with 2016 as Earth’s fifth-warmest December in 142 years.

At regional level, South America saw its third warmest December on record, while Africa and Oceania were among the eight warmest on record.

While, Both North America and Europe had above-average December temperatures, but it was the coldest December since 2016.
