  •  Another thing, Arctic ice extent seems... (4+ / 0-)

    to have increased its pace very significantly since the SSW event. It's above 2012 levels and almost at the 2000's decadal average. The Arctic ice seems to be amplifying tremendously, if 2012 is any indication. Larger in winter, ever smaller in the summer.

    Another "source", I believe, for the sudden warming would have to be the hotter oceans absorbing the sunlight as the Arctic ice melts. This would at least drop in a more intuitive explanation for the seeming paradoxical notion that less Arctic ice translates to colder, wetter winters at the mid-latitudes.

      there's not a lot of volume. The PIOMAS volume is about 1000 cubic kilometers below this time last year. Or look at the Navy's HYCOM drift chart. It shows a lot of thin ice moving around the central basin as quickly as if it were midsummer. Quicker than it would have drifted at midsummer a decade back.
