The decline in global industrial activity with the containment due to the coronavirus pandemic will have had no effect on the poor global warming figures. The latest data show once again how difficult it is to reverse movement.
June 2020 was the warmest month ever recorded in the world, on par with June 2019. These two months are "at 0.53 ° C above the average for the period 1981-2010", said , Tuesday, the European Copernicus service on climate change, after an already record month of May.
37 ° C over one hour in eastern Siberia
But it is above all the "exceptional warmth" over Arctic Siberia which catches the attention of the European service. The average temperature thus reached up to 10 ° C above seasonal norms in June. On June 20, a temperature of 37 ° C over an hour was even estimated in eastern Siberia, a record inside the Arctic Circle, according to Copernicus. The same day, in the same region, the station in the Russian city of Verkhoyansk had recorded a peak at 38 ° C, a possible heat record for the Arctic being verified by the World Meteorological Organization.
According to the European service, these "exceptional" temperatures are linked to various interacting factors, in particular the wind regime and a particularly weak snow cover. "What is worrying is that the Arctic is warming faster than the rest of the world," said Carlo Buontempo, director of Copernicus.
Increase in number of fires
As a result of this warming, an increase in the number of fires and their intensity in the far northeast of Siberia, and to a lesser extent in Alaska and the Canadian Yukon has been noted. According to Copernicus, these fires have already caused the emission of 59 megatonnes of CO2 into the atmosphere, against 53 megatonnes in June 2019. The year 2019 was already "very unusual", underlined the expert Mark Parrington, fearing an activity "Intense" in the coming weeks due to temperatures and soils that are less humid than normal.
Due to global warming, the planet has already gained more than 1 ° C since the pre-industrial era, causing a multiplication of extreme weather events such as heat waves, droughts or floods. 2019 was the second hottest year in the world, after 2016, and experts expect global average temperature to break a new record in the next five-year period.
