There are comments on the Real Climate weblog More bubkes regarding why I did not comment further on Arctic sea ice trends. This is because I weblogged on it in June in my post
I concluded that weblog with the text
“Until later in 2007, the sea ice areal extent continued to decrease in a manner which, at least visually, is consistent with the Vinnikov et al 1999 predictions (although the actual values of areal coverage differ substantially between the observations and the predictions, perhaps as a result of their formulation to compute areal coverage).
However, since 2006, the reduction has stopped and even reversed. Perhaps this is a short term event and the reduction of sea ice extent will resume. Nonetheless, the reason for the turn around, even if short term, needs an explanation. Moreover, this data provides a valuable climate metric to assess whether the multi-decadal global models do have predictive skill as concluded in the Vinnikov et al 2009 paper.”
It should be recognized that the Vinnikov et al plots are not at the time of the September minumum. I agree completely that the minumum in sea ice coverage in the last few years has been at record low levels, and, currently, the sea ice is melting at a rate that is greater than average (see).
I also want to repeat what I wrote in my July 2 2009 weblog Response By Roger A. Pielke Sr. To The Real Climate Weblog “More Bubkes”
By overstating what is actually occurring within the climate system (which they clearly did in their original weblog and perpetuated in their second weblog), they provide fodder for those who conclude that the human intervention in the climate system is minimal. To emphasize my view, it is summarized in my weblogs
