The Last 7 years have been the warmest on the record as planet approaches critical threshold
On an annual average, 2021 ranks slightly ahead of 2015 and 2018, with 2016 remaining the hottest.
A new analysis by the European Union’s Copernicus Climate Change Service, which tracks global temperature and other climate indicators, found 2021 was the fifth-warmest year on record.
The last seven years have been the seven warmest on record for the planet, new data shows, as Earth’s temperature continues its precarious climb due to heat-trapping fossil fuel emissions.
A new analysis by the European Union’s Copernicus Climate Change Service, which tracks global temperature and other climate indicators, found 2021 was the fifth-warmest year on record.
The goal of the 2015 Paris Agreement, to contain global warming “significantly” below + 2 ° C and if possible at + 1.5 ° C, is therefore still dangerously close.
And the last seven years “have been the warmest on record, by a clear margin,” notes the European body.
“This is a stark reminder of the need for us to change, to take effective and decisive measures to move towards a sustainable society and to work to reduce carbon emissions” underlined Carlo Buontempo, director of the change department. climate of Copernicus.
The agency has measured new record concentrations in the atmosphere of greenhouse gases produced by human activity and responsible for global warming for 2021.
Though the long-term trend is up, yearly fluctuations in global temperature are expected, mainly because of large-scale weather and ocean patterns like El Niño and La Niña, the latter of which was present in 2021 and tends to lead to cooler global temperature.
“The really important thing is to not get hung up on the ranking of one particular year but rather kind of see the bigger picture of ever-warming temperatures, and that ever-warming doesn’t mean every year will be warmer than the next,” said Freja Vamborg, senior scientist at Copernicus. “But that was what we’ve seen so far with every decade warmer than the next — and this is quite likely to continue.”
Earth’s average temperature is around 1.1 degrees Celsius above average pre-industrial levels, Copernicus reports, 73% of the way to the 1.5-degree threshold scientists warn the planet must stay under to avoid the worst impacts.
