The scientists say that unprecedented levels of heat in the Arctic and Siberia were key factors in driving up the overall temperature. The past 12 months also saw a new record for Europe, around 0.4C warmer than 2019… The Copernicus data comes from a constellation of Sentinel satellites that monitor the Earth from orbit, as well as measurements taken at ground level…_ _Globally, the 10-year period from 2011-2020 is the warmest decade, with the last six years being the six hottest on record._ The article points out that in some parts of Siberia and the Arctic, temperatures for the year [were six degrees C above the long-term average](https://www.bbc.co.uk/news/science-environment-53140069). “This exceptional warming led to a very active wildfire season. Fires in the Arctic Circle released a record amount of CO2, according to the study, up over a third from 2019.”
