The years from 2014 to 2020 were the hottest on record with both 2020 and 2016 hitting the record for the single hottest year. Values for the reported data are from the ECMWF Copernicus Climate Change Service ERA5 dataset, now dated 1979.
The year 2020 was 0.6 degrees Celsius warmer than the average between 1981 and 2010 and about 1.25 degrees above the pre-industrial period of 1850-1900.
Meanwhile in Europe it was The hottest year on record, 0.4 ° C is warmer than 2019, and earlier this year was the warmest year.
The climate crisis did not take a break previous year.
The bloc's space programs include the Copernicus earth observation satellites. One key factor driving up the temperatures was the heating experienced in the Arctic and Siberia. In some locations there, temperatures for the year as a whole were 6C above the long-term average.
Some regions previous year experienced warming well beyond the global average, according to the Copernicus report, based largely on satellite data. Fires in the Arctic Circle released a record amount of CO2, according to the study, up over a third from 2019. This is particularly remarkable, as 2020 was not under the influence of an El Niño, a mode of natural climate variability in the tropical Pacific which "supercharged" 2016 with extra heat.
Temperature analysis checks are regularly carried out by European Union scientists, as well as by other scientific institutions like NASA. The scientists say that the closeness between the years is all the more remarkable considering the impacts of the El NiÃ±o/La NiÃ±a weather cycle. Twenty-sixteen was made warmer by a strong El NiÃ±o event while 2020 was made slightly cooler by an emerging La NiÃ±a in the second half of the year.
2020 was the warmest year in Europe, and winter 2019/20 I am Fall 2020 They were also the warmest.
The heat wave in the western US also resulted in a record fire season in several USA states but especially in California.
2020 will go down in history for many things, but another added to the list today ranks 2020 as the joint hottest year on record globally with 2016.
"The extraordinary climate events of 2020 and the data from the Copernicus Climate Change Service show us that we have no time to lose", said Matthias Petschke, Director for Space in the European Commission, the EU's executive arm.
This also marked the end of the hottest decade ever recorded according to the service, with the last six years topping the decade.
CO2 concentrations in the Atmosphere are forecast to rise to 417 parts per million this year. The Met Office says that Carbon dioxide will exceed 417ppm in the atmosphere for several weeks from April to June. This is 50% higher than the level of 278ppm that pertained in the late 18th Century as widespread industrial activity was just beginning. "The human-caused build-up of Carbon dioxide in the atmosphere is accelerating", said Prof Richard Betts from the Met Office.
"Since CO2 accumulates in the atmosphere like water in a bathtub, if we turn down the tap by 7%, the CO2 level just rises a bit more slowly", Stefan Rahmstorf, head of Earth system analysis at the Potsdam Institute for Climate Impact Research, said.
