Hudson's Bay has a huge influence on climate in Eastern Canada. The tree line plunges around this big mass of water. Could there be some synergetic effect between Hudson's Bay freezing later/thawing earlier and weather patterns over Greenland?

More from Greenland
Greenland's glaciers and ice sheet have become an integral part of this blog. Perhaps it should be renamed to ASIGIS blog? ;-) This clip from the Chasing Ice documentary has been doing the rounds lately. It's showing the largest iceberg calving ever filmed, with 7.4 cubic km of ice crashing off ...

Record dominoes 13: CT global SIA maximum
I doubt this is the end of the record streak, but as we approach the end of the year, this will probably be the final record domino of 2012. And what a fitting number to end it with! The record fell over three weeks ago (see data). The reason I'm reporting it now is not just because I'm lazy o...

Russia has now started construction of three very large nuclear ice breakers which will allow for year round shipping via the northern route.

As Sea Ice Declines, Winter Shifts in N. Alaska
As winter sets in, the Arctic Ocean freezes up. But because waters near the continental land masses warm up so much during the melting season (see for instance this image from August 11th 2012), they have to give off a lot of heat before they're cold enough to freeze. The waters warm up so muc...

CT SIA anomaly drops below 2 million km2
With a drop of 174,867 square km for July 17th reported by Cryosphere Today (run by the Polar Research Group at the University of Illonois at Urbana-Champaign), the 2012 sea ice area anomaly has dropped below 2 million square kilometres, compared to the 1979-2008 mean: So what, one may ask. It ...
I was wondering what effect the earlier and warmer influx of fresh water from the rivers flowing into the Arctic may be causing

With things looking so serious in the Arctic right now, it was high time for another corny pun! Instead of doing three different posts, I'm combining three different comparisons of fringe regions for today's date. Of course, I'll be using the excellent University of Bremen sea ice concentration ...

Arctic methane: Russian researchers report
I vowed not to talk about this because it literally makes me sick to my stomach, but it's too important to deny. We all know about the vast deposits of methane clathrates on the Siberian continental shelf. They are kept in place by pressure and low temperatures. However, the temperatures (SAT as...

Russia ordering 6 new icebreakers for the northern route..
"According to the news agency, Ivanov believes goods turnover at the Northern Sea Route could reach five million tons in the course of 2012. The new icebreakers are needed for the follow-up of the quickly expanding Arctic shipping."

Northern Sea Route almost open
Unfortunately we can't check the satellite images, because clouds brought in by low-pressure systems are blocking the view on practically the entire Siberian coast, but it looks like the Northern Sea Route is opening up for real. Check the Uni Bremen sea ice concentration map: I'd venture to s...

In anticipation of the next SIE update I'm going to look back at what air and sea surface temperatures did in the past month, and compare that to what happened in previous years. This month of June saw the AO Index go negative, which means that large parts of the Arctic have been relatively cl...
