Last year was the joint hottest year on record globally , tied with 2016 , and the hottest year ever tape for Europe , according to fresh information free by theCopernicus Climate Change Service(C3S ) .
scientist hadpreviously speculatedthat 2020 was going to be one of the hot years on record but it ’s just been confirm by the C3S.The data point indicates that 2020 was 0.6 ° C ( 1.08 ° fluorine ) affectionate than the touchstone 1981 to 2010 reference full stop and around 1.25 ° C ( 2.25 ° F ) above level before the industrial gyration .
While 2020 was on a par withthe 2016 record , 2016 was leave an superfluous encouragement from El Niño , a short - full term rising in sea surface temperature in the tropic Pacific that tends to more or less increase temperatures across the earthly concern every two to seven years . 2020 , however , did not have this extra advantage – in fact , it was aLa Niña year , El Niño ’s colder counterpart – yet it still managed to match 2016 .
Last class also assure one of thebiggest drops in carbon dioxideemissions since the end of World War Two due to the COVID-19 pandemic . Unfortunately , this ishighly unlikelyto have any meaningful impact on the State Department of the major planet ’s mood crisis in the short or long term . The new C3S satellite data also showed that carbon dioxide concentration have continued to rise in 2020 , albeit at a somewhat deadening pace than previous years , reaching a concentration of 413.1 parts per million in our atmosphere .
“ While carbon dioxide concentrations have risen somewhat less in 2020 than in 2019 , this is no effort for complacency . Until the nett global expelling subdue to zero , CO2will continue to cumulate in the aura and drive further mood alteration , ” Vincent - Henri Peuch , Director of the Copernicus Atmosphere Monitoring Service ( CAMS ) , explained in astatement .
The year was one of theworst old age on recordfor the Arctic . Off the back of an exceptionally warm X , the average yearly demesne - surface air temperature in the Arctic measured between October 2019 and September 2020 was the second - tender since record - holding began in 1900 . As a result of these temperatures , the Arctic endured the second - miserable Arctic minimum sea ice extent . The Siberian Arctic also experienced a freakishlyhigh number of wildfires , surpassing the record - breaking fire activityseen in 2019 .
On top of unusually warm temperatures in the northern polar regions , the world also saw amassive uptick in tropic stormsin the Atlantic . This twelvemonth has break the single - season record for the most name hurricanes in the Atlantic , previously hold by the 2005 hurricane season with 28 violent storm . In fact , that ’s so many hurricanes , the World Meteorological Organization eat up their standard listing of alphabetical name for storms and were forced to turn to the Greek alphabet .
" 2020 stand out for its surpassing warmth in the Arctic and a record number of tropical storms in the North Atlantic . It is no surprise that the last 10 was the warmest on record , and is yet another reminder of the importunity of challenging emissions reductions to forbid adverse climate impacts in the future , ” said Carlo Buontempo , Director of the C3S.
