The Arctic Circle likely experienced a record setting temperature of 100 °F over the weekend in Siberia during a historically unusual period of high heat for the region.
The Siberian town of Verkhoyansk measured a temperature of 38 °C (100 °F) on June 20th likely setting a new temperature record for the region. The high temperature occurs as the Arctic Circle has been experiencing a heat wave that brought temperatures up to 10 °C above average throughout the months of March to May. Unfortunately, the Copernicus Climate Change Service reports this past May was the warmest May on record, suggesting that more high heat events are likely for the Arctic in the future.
As higher average temperatures become common in the Arctic Circle, the surface albedo, an index that describes how reflective a surface is, will decrease because of snow and ice melt. As the snow and ice continue to melt, a positive feedback loop is created which heats the Arctic further and will likely make record setting temperatures more common.
Not good news.
