2018 Arctic sea ice minimum

Another great video, this time from NASA Goddard:

That's a really cool way to use icesat2. I'm excited about all the stuff they are going to do with that satellite.

Hold the presses ! 3rd place is 2018 extent at this moment. With significant floating snow masquerading as sea ice, don't want to minimize the minimum fans, but sea ice is a little more complicated to fathom than summed up on one day a year....

The action is systemically baffling if not considering a slow but gradual thinning of sea ice.

At edge of growing North Pole darkness, melting sea ice:

The same CAA North of Canada Polar Vortex circulation dominating 2018 is now getting back its strength, cold, in fact coldest upper air in years, yet driving warm air North of Greenland during spring autumn and winter virtually non stop is also the key factor causing this sea ice to stall in refreezing, there is of course warm sst's and pervasive clouds.

Keep an eye on Leslie and Walaka, let alone Kong Rey and all the big 'uns going past Japan. I don't think this story is over. The interlocking cogs of the hemispheric (or global, if you prefer) circulatory system are crazy and getting crazier.

I'm not a close enough observer to say if temps are warmer than usual around the Arctic, but it seems to me they are. Lotta push going on there.

The one and seven day anomaly graphs for Arctic Temperature are going off. DMI Temp graph for Oct 3 of course proves things to be a scary reality....

There is complexity in this warming which can be exploited by the usual "new ice age" gangs. 2018 CAA based vortex which wobbles, grows bigger, gets smaller, eerily reminds of hurricane eye cycles, a planet sized cold air Arctic eye which turns counterclockwise at its perimeter, sometimes spinning off a rogue smaller vortex which usually has very cold air at its center, this colder air is the source of weird snow events of late. It is very fascinating to watch the cooling center of smaller vortices, this said, the current larger main one, is huge compared to recent 5 years. Despite this, sea ice extent is being rocked to record lows, never mind the minimum, in a few days 2018 will be 2nd lowest in extent, from 6th to 2nd in 2 weeks. Again with very unfavorable melt season in mind, 2018 still surprises, we look at New Siberian Island snow covered Island which lost nearly all its snow cover a few days ago:

Likely by warm air sublimation, something that happens near very high mountains, but Siberian Islands are not high at all, note of interest this snow free event should be wondrous for North Siberian residents, the quiet people.
But it is likely a very rare event, if not unique for New Siberian Islands which apparently has a population of 2.

Lol, DMI Temp

is still going crazy

and now the 30 day anomaly is going off!

There is still some melting to be seen whenever clouds clear away:

Now we can see the big vortex indirectly here:

East of Rockies gets whacked with its Southward flow, brrrrrr colder, on the east North American coast record or very warm temperatures on the Northward flow side. This is the real big weather non-news with populated areas you can only get on Neven's blog, because we look at sea ice which impacts the wider world general circulation. This larger vortex is particularly peculiar to 2018, why exactly Siberia is not so cold is the other non news event affecting even larger populations and is part of huge warming in the North Pacific area:

Again the opposite of the vortex influencing North America weather is clearer skies over the North Pacific.

PIOMAS data including Sept 2018 was published yesterday, so have updated the Ice Cube video.
(I'd already rendered the first 760 frames in anticipation!)
