The Beaufort cracking event has really spread into more central regions in the last 1-2 days. (When viewed on Lance Modaps) Could the entire region become unstable?

Cryosat-2 confirms: sea ice volume is low
Last month I made a comparison of CryoSat-2 sea ice volume distribution maps for the 2015/2016 Winter analysis, but it was off because the dates didn't exactly match. Better images have emerged during this year's General Assembly of the European Geosciences Union (more on that later this week): ...

Crowd-Source Prediction of September Sea Ice Extent (July report & call for August predictions)
In mid-June through early July, participants on the Arctic Sea Ice (ASI) blog posted 82 individual predictions for the mean NSIDC September Arctic sea ice extent. The median value of these 82 predictions was 3.2 million km2, with an interquartile range (approximately the middle 50% of prediction...
3.6 Mkm2
I tend to believe PIOMAS and it thinks there is more ice now than last year. There has been the suggestion that PIOMAS overestimates the thickness / volume of thinner ice. There seems to be more of that this year which could then prove me wrong.
I do think the PAC has tended to spread the ice and this year will start to catch 2012 soon. I am expecting the the Laptev bite to see to that.

Perception of the Arctic
There was a time, not too long ago, when I didn't know the Arctic existed. Sure, I knew there was a North Pole and that it was cold there, but somehow I always thought that the Arctic and the Antarctic were the same thing, that someone had forgotten to add the Ant-. And of course, polar bears ...

Could the persistent CAB high pressure move significant multiyear ice into the Beaufort sea. It would be difficult for it to survive a summer there.

I suppose thats sticking my neck out.
If the high pressure persists where it is, then melting and compaction in the Barents sea might just match gains in the Bering sea, untill the sun returns again.
