(or much sooner) http://dotearth.blogs.nytimes.com/2010/03/22/new-light-shed-on-north-pole-ic e-trends/ The bottom line, expressed here before, is that no one should expect to find much broad meaning in short-term variability in Arctic sea ice - in one direction or the other. If there is a death spiral, expect <http://dotearth.blogs.nytimes.com/2009/10/06/spread-of-thicker-arctic-ice-s een-last-summer/> a lot of loop the loopsalong the way.

The attached paper indicates that around half of the normal September sea-ice should still be around in the 2020-2040 time frame. Boe, J., Hall, A., Qu, Z. Nature Geosci 2, 341-343 (2009). I am not saying that the situation in the Arctic is not dire, however, are the suggestions that September sea-ice in the Arctic is soon to be a thing of the past a bit overblown and without foundation?
