There it is, the first Sea Ice Outlook of this year. The SIO is organized by the interagency "system-scale, cross-disciplinary, long-term arctic research program" SEARCH (Study of Environmental Arctic Change), and is a compilation of projections for the September 2012 Arctic sea ice extent, based on NSIDC monthly extent values. These projections are submitted by professionals as well as amateurs, such as our own Chris Randles and Larry Hamilton.
Here's the summary for the June report:
With 19 responses for the Pan-Arctic Outlook (plus 6 regional Outlook contributions), the June Sea Ice Outlook projects a September 2012 arctic sea extent median value of 4.4 million square kilometers, with quartiles of 4.3 and 4.7 million square kilometers (Figure 1) [The median value for the 2011 June SIO was 4.7 million square km, N.]. This compares to observed September values of 4.6 in 2011, 4.9 in 2010, and 5.4 in 2009. Both the 2012 quartile values and the range (4.1 to 4.9) are quite narrow. The 2012 June Outlook differs from all previous Outlooks in that there are no projections of extent greater than 5.0. It is always important to note for context that all 2012 estimates are well below the 19792007 September mean of 6.7 million square kilometers.

(93 posts)Well, either you're closing your eyes
To a situation you do not wish to acknowledge
Or you are not aware of the caliber of disaster indicated
By the presence of a pool of water on your sea ice
Ya got trouble, my friend, right here,
I say, trouble right here in River City.
