Heh.

Even so, I'm fascinated by how steady the variance from average is... right around 300K KM2, for almost 10 days now.

Could we possibly blow by the 2000's average sea ice extent on our way to the 1990's average?


http://www.ijis.iarc.uaf.edu/en/home/seaice_extent.htm


And, given the sorry state of the ice, what is driving this rapid increase in extent? I keep hearing Chris say, "It's the weather." Probably right but we will get a host of noise from the deniers that it is the climate.

This month has seen a pretty sharp slowdown, suddenly. And that's been true for other extent/area metrics and not just IJIS. As it stands, 2013 is tacking closer to the recent trend-line of the the late 2000s/early 2010s years than the early/mid 2000s years.

The recent slowdown in extent growth appears very unusual. Only 2011 shows something similar. Is this compaction?

2011 had a strong "fram flush" pattern around this time, just like this year.  interesting

Despite the dramatic increase in the minimum SIE this melt season, the freeze is looking an awful like last three minimum extent years.

http://www.ijis.iarc.uaf.edu/en/home/seaice_extent.htm

This certainly is not due to a strong "fram flush". Doesn't this have to be due, at least in part, to difficulty in refreezing?

Although judging by the N Pole webcam data there is a strong southerly flow through the Fram.  The cam is moving about a degree per week and is now at 78.08ºN, south of Longyearbyen.

Update, it's moved 2º S in the last week.

If this portends a weak freeze this season it could be quite interesting. Given Chris's evidence that volume is the best predictor for an approaching melt season, I'm going to follow his posts closely.

Think someone predicted (less than?) a week ago that with Hudson more or less filled and little ice outside Bering strait there would be a period of slow growth. It seemed pretty sensible and I don't think we should read too much into slow growth in last week meaning anything about slow growth for rest of freeze season.

NSIDC extent has also fallen to 3rd lowest and if CT area continues to follow extent as it appears to have been doing we could reach 3rd lowest there as well. 3rd appears to be lowest rank since early in 2013 so certainly interesting enough to note, but I would suggest avoiding reading too much into it such as anticipating rest of freeze season.

Reasonable, crandles.  I'm more concerned about the high temperatures hindering thickening.  The lack of freeze in the Bering can almost directly be attributed to the heat flow around the persistent high pressure ridge in the north central pacific.  Similarly some of the push back in the Barents is coming from flow following the Gulf Stream.  I'm not surprised that the Hudson and Baffin are proceeding as normal... They are closer to the current "cold pole" in the CAA. 

In short, it's not coverage I'm obsessing on right now, but volume.

Before getting too exited about the lower-than-2012 ice cover: the reason lies in the Sea between Iceland and Greenland. Last year an intense wind field appears to have caused a field of false ice clearly seen in the images for a couple of day's.
This should last for two days more, after that the situation can be better evaluated.

I realize sea ice area is falling out of vogue (for obvious reasons). but I thought I'd mention that as of yesterday's century break, Cryosphere Today's has Arctic sea ice area at 11.749 million km2. That's the 3rd smallest on record for the date, but also a whopping 582,590km2 below the same date in recordsetting 2012. (In fact, while I am not in any way implying that it will or could happen, were the remainder of 2014 to exactly follow the 2012 path from now onward, this year's minimum area would wind up at a ghoulish 1.65 million km2.)

At any rate, looks like another interesting and very educational year is in the works...

You mean the Arctic ice sheet is NOT recovering like Joe Bastardi promised?  SHOCKING.... :)

On a less satirical note.....I wonder if the stubbornly warm north Pacific has anything to do with the low level of ice growth since November?  There has been a rather large "warm anomalous area" of SST off the west coast of the US which has been there for 2 - 3 months now and has been INCREASING in its "intensity" over the past month.  And while I am NOT a science geek (I say that lovingly btw).....it likely is playing a part in the extremely dry conditions in the western US (especially California).

Tell me if I'm wrong, but isn't that set-up associated with a negative PDO? Funny that a tiny sliver of blue along the US/Canadian coast determines whether it's positive or negative.

CT SIA has reported a century break and has now dipped into 3rd spot.

Something else: Do you guys think we should have a central spot to discuss SIE and SIA, instead of separate threads for CT and IJIS and NSIDC? Something like a 2014 sea ice extent and area data thread?
