Check the GISS Surface Temperature Maps (https://data.giss.nasa.gov/gistemp/maps/index_v3.html https://data.giss.nasa.gov/gistemp/maps/index_v3.html) how the temperature anomalies were distributed around the world in the months of this year. In the upper latitudes you always have big patches with 4+C over the average of 1951-1980, the anomalies are not so extreme in the rest of the world. And in those regions in particular have 2 possitive feedback loops, with less snow the land absorb more heat, and then the "unexpected" release of methane.
