Arctic Sea Ice Extent At Record Lows; Entire Arctic Basin 5.5C Above Normal, Some Areas 25C
Thats how much warmer than normal the entire region of the Arctic above the 66 degree North Latitude Line was earlier today. Areas within this large warm pool saw temperatures spike to a range of 15 to 25 C warmer than the already warmer than normal 1981-2010 base period. And broad regions saw temperature between 10 and 20 C above that 30-year average.

Its just a snapshot. But day after day, week after week, month after month, the story has been much the same throughout Fall and Winter of 2017-2018. And as during last years ridiculously warm Arctic winter, the sea ice has taken a considerable pounding. Yesterday dropping to a new record low extent of 13.774 million square kilometers. Beating out the previous record low for the day set just last year. And dipping more than 1.8 million square kilometers below the 1979-1990 average. A period that already featured greatly reduced Arctic sea ice cover when compared to extents seen in the early 20th Century.
