@Jai Mitchell, your material is fascinating.

I don't actually suffer from "east coast bias" nor do I ignore the plight of Canada and the south, since those "blobs" from the Arctic (reducing it to the most vulgar language to make clear how rough is my thinking) have some rather wholesale effects in various parts of the globe. Water vapor animations have been my daily study for many years now; here's a favorite, but of course Nullschool and Maine Climate Reanalyzer have provided more visual input.

I don't discount the Pacific, but am puzzled as to why Dr. Trenberth, for example, tends to make it either/or with Dr. Francis when it's clear the containing nature of the Arctic circulation is broken and having knock-on effects and the effects interact/add to each other. Of course the Pacific is a gigantic input. Yes, this is lay language, but most of the world are laypeople (more than 99%) and when people "get" it in local terms it is quite helpful. It's clear that there is more blocking and it's clear that the normal patterns of hot and cold are reversed. My niggle is whether or not the cold is "leaving" the Arctic as opposed to, say, being generated by it. I talked with Tenney Naumer about this; her understanding, of course, is much more accurate and complete than mine.

I finally realized that continuous wave generation is not the same as actual movement, that things are transmitted without the original stuff moving. (Once again, terrible sloppy language, I know.)

Of course, we all are thinking, one way or another, "how bad is it?" (sloppy again). Is the reversal of hot and cold as disastrous as it seems from here?

Great late melting action with surface air temperatures lesser than 0 is far less boring as 2014 melt season ends.

That's right, Wayne.
Not boring at all. Drop for the day about 33K, which is extreme that late in the season. Only 2005 had such decline for the day (-50K).
Interesting, sea ice declines while peripheral lands start to get a first snow cover.
NW passage is almost blown open, sea ice in the East Siberian Sea is reduced to scattered floes and ice-milk.

Here's an update to the Arctic Sea Ice Bucket Challenge - it's just beginning to go viral!
