Major Warming Event Projected For Arctic Over Next Five Days; Regionally, 10-20C Above Normal Temps
It’s been consistently, abnormally, warm in the Arctic for about as long as any of us can remember. But during recent years, the changes — caused by a massive and ongoing accumulation of heat-trapping gasses in the Earth’s atmosphere — appear to be speeding up.

This week, two major warm air invasions — one issuing from Siberia and another rising up through the Fram Strait and extending north of Greenland are expected to bring locally 10-20 C above normal temperatures and accelerate early season sea ice melt in an already reeling Arctic.
EDIT
Today, a wedge of above-freezing air is invading the Laptev Sea north of Central Siberia. Strong southerly winds issuing from Central Asia are running north into the Arctic Ocean. They bring with them 10 to 20 C above average temperatures for this time of year — which is enough to push readings as high as 35 degrees F (2 C) over what during the 20th Century would have been a solid fringe of the polar ice cap.
Over the next 24 hours, this leading edge of warm air will spiral on toward the East Siberian Sea — bringing above freezing temperatures and liquid precipitation with it.
