2023 was the warmest year ever recorded since this type of measurement has existed, i.e. since 1850. communicated today, Tuesday 9 January 2024, the Copernicus Climate Change Service of the European Union.
“This was a truly exceptional year, from a climatic point of view, unprecedented, even when compared to other very hot years,” said the centre's director, Carlo Buontempo.
Comparing paleoclimate data from sources such as tree rings and air bubbles in glaciers, Buontempo also said that 2023 was “very likely” the warmest year in the last 100,000 years.
Last year, on average, the planet recorded 1.48 degrees centigrade more than the pre-industrial period 1850-1900, beating the previous record of 2016 and getting dangerously close to that +1.5 considered the maximum threshold not to be exceeded, under the Paris Agreement
2023 was also the first year in which every day the temperature was at least one degree higher than in pre-industrial times.
Not surprisingly, the concentration of carbon dioxide in the atmosphere has risen to the highest level ever recorded, equal to 419 parts per million.
