The plural of phenomenon is phenomena. Apart from that, a great article.
As we approach the final stretch...
For years we've talked about one of the most fascinating phenomena of Arctic sea ice loss as it progresses from year to year: The moment when the ice disappears regardless of the weather. We've seen some of that, back in July 2012, when extent and area numbers kept going down steadily, even tho...
Wipneus: If you did the calculations with only the data from, say, 2000 I think you would find that the standard deviation is less (although the set is now rather small). The year 2007 is supposed to be an exceptional year, and yet it is only ~1.5 SD below the trend, which indicates that there is room for improvement in the way the algorithm calculates the variability. Probably not worth worrying about it too much though!
PIOMAS August 2011 (new volume record)
The PIOMAS graphs at the Polar Science Center of the Applied Physics Laboratory at the University of Washington have been updated. I'd like to start by showing Larry Hamilton's excellent graph that gives the best perspective: It's already below last year's very low low. In other words, a new...
An observation about the last of the graphs at the top (minimum ice volume): in recent years the points are mainly within 1 Standard Deviation of the trend line, and never much more. However, in the earlier years there are many points which are well over 1 SD from the trend line.
This means that the variation is getting smaller in absolute terms but not so much in percentage terms (unsurprisingly). So if the trend continues then zero will almost certainly be reached in 2014 or 2015, and the range of possibilities is much less than the graph suggests.

I have been lurking here for some time, but I have just come across this:

I don't know how much bearing this has on the discussion.
SIE 2011 update 18: ten yard line
During the melting season I'm regularly writing updates on the current sea ice extent (SIE) as reported by IJIS (a joint effort of the International Arctic Research Center and the Japan Aerospace Exploration Agency) and compare it to the sea ice extents in the period 2005-2010. NSIDC has a good ...
With the volume of ice shrinking so rapidly I am surprised that anyone would predict a greater extent than September 2010!
http://www.grinzo.com/energy/2011/05/11/arctic-ice-volume-definitely-not-good-news/
On that basis (and wishful thinking) I expect the actual value to be lower than all the predictions, about 3.8.
SEARCH 2011 Sea Ice Outlook: June report
I'm a week late to this particular party (and some others), but this is something we'll want to reference later on (just like we did last year in June and July). SEARCH has released its first Sea Ice Outlook report, to which several people or groups of people - mostly science professionals - sub...
