Looks like global sea ice has crept up above the +/- 0 anomaly at Cryosphere Today.

Well, I sent an email to caitlin about their live data feeds -- I didn't get a response. So I sent a follow up email yesterday. Whataya know? They removed the live ice thickness feed from the page completely, but they did turn on the live bio telemetry feed. www.catlinarcticsurvey.com/live_from_the_ice.aspxWho was it that predicted this first?

Well, barring a very late, large and unusual surge of ice extent growth, 2009 marks the earliest peak of the Arctic winter ice extent since the dawn of satellite monitoring. I wonder if there's anything to that?

I wonder if there's anything to that? I don't think so. You are just looking at weather. If you fit a curve to the whole winter maximum, (instead of looking at the random ups & downs, then 2009 has a later than meantime peak. 2009 has more of the shape of the 2003 year - another year in which the great lakes froze. Looking at the JAXA chart, 2005,2006, and 2007 had low winter maximum's and early thaws. 2009 is up there with 2004 and 2008. 2003 appears to be the record freeze in the AMSR-E series.

I dunno why you feel you have to argue against the facts -- but you may certainly feel free to cherry pick, interpolate or fit the data with whatever formula you like to meet your expectations, but the numbers and the dates are the numbers and the dates. Do the facts scare you?
(You do know that I'm just yanking on yer chain a little bit, right?) What's today's date down unda?

Check out the Biometric feed from the Catlin Arctic Survey Pen Hadow's core temp is below 92 deg (severe Hypothermia) I think its time for them to call for evac and give up on the expedition until global warming starts again Medic1532 www.catlinarcticsurvey.com/live_from_the_ice.aspx

These extreme temperatures, the coldest experienced by the team so far in this expedition, have the strange physical side effect of causing the team to sound almost drunk as they slur their words and cognitive reactions are noticeably slower.
The relentless cold is utterly exhausting, but despite this, the team crossed the 83°N landmark and covered nearly 14.5km. "I would think the writer will be removed from the staff shortly. Interesting to note that the web-temp hits 'bottom of the scale' at -45°C. Wishful thinking - or deliberate?

NSIDC reports that the maximum sea ice extent in the Arctic was reached on Feb 28th. The Japanese report the date as March 6th. It porobably does not matter at all, but it does indicate some difficulty in establihing precisely what the data is.

I'm a novice, so bear with me. If the Catlin team reports temps of -45C at latitude 83 N, why is the Arctic ice extent declining?

I'm no expert, but I'll take a stab at your question.
First off it is a big ocean out there. Temperature in one tiny spot at that latitude doesn't say much about temps elsewhere.
Secondly, sea ice gets blown around and pushed up on itself and pushed onshore/ If the ice has stopped growing, ice extent (which is the area of the surface of the ocean that has 15% or more ice coverage) will likely fall.
Again, just my guesses.

I just looked up the catlin bio telemetry and pen hadow is showing 77.1bpm and 34.49c Ann Daniels is showing 122.4bpm and 37.41c and Martin Hartley is showing 93.3bpm and 37.19c Now after running my extremely complex catlin climate model, this tells me that Ann and Martin are in the same sleeping bag and it's her turn on top! Ah well, one way to fight the cold, and a good one at that!

thanks, ron. i think many lay people like me see declining ice extent and assume melting ice. Even in a big ocean it seems counter intuitive that with it -45C in some portion of the arctic, it could be above 0C elsewhere. (I assume ocean ice melts at about 0C) Even so, new ice should still be forming where it's way below freezing. Wind compacting the ice makes some sense as well, although one would expect that to happen in the dead of winter as well.
by the way, if that Catlin guy's body temp is accurate at 34.19C, someone needs to start treating him for hypothermia. He could be in serious trouble, and is probably jhaving difficulty functioning.
