Storm seems to be having some effect in thickness.

Second storm
There's another storm brewing in the Arctic, the second this year after PAC-2013, the persistent Arctic cyclone that stayed in place for weeks on end and caused the first half of the melting season to be very slow. And also the second storm after last year's Great Arctic Cyclone, the iconic im...
I thought I was looking at todays image, but that was yesterday. I think it is massive fires.

While keeping an eye on day-to-day data and speculating about whether 2013 is going to overcome the odds and break last year's records, one tends to forget about the wider implications and what this actually is all about. A tree is incredibly interesting, but in the end it's all about the fore...
Does anyone know if this is a big fire in the heat-wave area, or just gray clouds? More fires are supposed to warm the permafrost by darkening the soil, leading to more methane release.

I was thinking last month that the Beaufort was not opening up as usual due to the PAC. The winds were pushing into that region, so it seemed from hycom/CICE, but I don't have time to look back at the data.

I'd like to point out that for extent (http://meteomodel.pl/klimat/arcticice_nsidc.png), this year is about where 2007 was at this point, or with DMI (http://ocean.dmi.dk/arctic/plots/icecover/icecover_current_new.png), about equal to 2009, which diverged with 2012 only at the end of July. For area (http://meteomodel.pl/klimat/arcticice.png) it's below 2009 and almost same as 2011. 2011 and 2012 area diverged on day 210. Just looking at extent or area doesn't always tell us a lot.

Jim, thanks. I've been looking for events such as this, hypothesizing that the reduced area of multi-year ice will become more mobile as it shrinks. I wonder if this "Morris Jesup Polynia", which seems to be freezing over leaving the old ice offshore, will make it more likely that section of old ice will be shunted south.

All models are wrong, but some are useful, as the saying goes. However, when looking at how Arctic sea ice decline is modeled, one might be tempted to say that all sayings are useful, but some are wrong. To be fair, I should be the last person taking a piss at climate models. Hundreds of brill...
Latest images, it looks as though a bomb has gone off on the north coast of Greenland, with large fractures connected to Ellesmere.

It looks as though the "ridge" of older ice has moved from between Wrangel and the New Siberian Islands, to directly pole-ward of the New Siberian Islands. First year ice on the chart pole-ward of Franz Joseph has been eaten away. Does this seem correct? Any significant first year ice left?
