The Earth in 2021 was about 1.1 degrees Celsius warmer than the average of the late nineteenth century, the beginning of the industrial revolution and according to the Paris Agreement we must try to contain this "fever" within 1.5 degrees compared to pre-industrial period.
To say it are the scientists of NASA and Noaa.
The Earth's global average surface temperature in 2021 was 2018 and the sixth warmest on record, according to independent analyzes conducted by NASA and the National Oceanic and Atmospheric Administration (Noaa).
Overall, the past eight years are the warmest since the survey began in 1880.
The planet's long-term warming trend continues, with global temperatures in 2021 0.85 degrees Celsius above NASA's 1951-1980 baseline average, according to scientists from the Goddard Institute for Space Studies (Giss) of NASA in New York.
"Science leaves no room for doubt: climate change is the existential threat of our time," said NASA administrator Bill Nelson.
"Eight of the 10 hottest years on our planet - he adds - have occurred in the last decade, an indisputable fact that underlines the need for courageous action to safeguard the future of our country and of all humanity".
