Climate: The last nine years are among the ten warmest on record

This is a ranking that Humanity would have done without. The last nine years are among the “top 10″ of the hottest years ever recorded on Earth, and 2021 ranks sixth, according to the annual report of a leading American scientific agency, released Thursday.

“The nine years from 2013 to 2021 are among the ten warmest years on record,” the US National Oceanic and Atmospheric Agency (NOAA) said in releasing the data, which once again highlights the extent of global warming.

1,04°C more recorded on average

And the missing tenth year does not go back far, since it is 2010 (placed in ninth position). This trend had already been highlighted on Monday by the European Earth observation service Copernicus , which had highlighted that the last seven years have been so ” net” the hottest ever recorded.

He had ranked 2021 in fifth place, but he It’s not uncommon for agencies to show slight differences in their data. According to NOAA, 2021 turns out to be the sixth warmest year since records began in 1900. The average temperature recorded last year was thus 1.04°C higher than the pre-industrial era (1880-1900).

A current trajectory deemed “catastrophic” by the UN

The objective of the Paris agreement is to contain global warming “significantly” below +2°C, and if possible at +1.5°C, compared to pre-industrial era. But the emission reduction commitments made by the various countries, including those announced at the COP26 in November, leave the world on a warming trajectory of 2.7°C, a level qualified as “catastrophic” by the UN.

20220107The average of 2021 was pulled down by the La Nina weather phenomenon, which tends to cool temperatures, NOAA notes. But the agency points out that the average land surface temperature in the northern hemisphere last year was listed as the third highest since 26.

The European and American agencies agree that 2013 remains the hottest year on record. The ongoing global warming, of unprecedented speed and amplitude, is clearly attributable to human activities and in particular to fossil fuels (gas, oil, coal), which have been massively used since the Industrial Revolution.
