Arctic Death Spiral: Sea Ice Passes De Facto Tipping Point Thanks to Deniers, Media Blow The Story, Again
Arctic sea ice volume by month in cubic kilometers. The bottom (black) line is September volume. The plot makes projections with simple quadratic trend lines (details here [ http://neven1.typepad.com/blog/2011/08/piomas-july-2011.html ]), which likely oversimplify matters as we approach zero volume (especially for non-summer months). But reversal of the overall death spiral is highly implausible absent an even more implausible reversal of current climate policies — policies which are promoted by denier disinformation and sustained by media stenography.
Figure: Carbon emission (in billions of tons of carbon a year) from thawing permafrost.
