Whilst the usual suspects provide compelling demonstrations of just how the motivated rejection of science works in practice, my eyes remain fixed on the far north, where the Arctic melt season is drawing to a close. Above is the current (Sept 3rd) NSIDC sea ice extent graph, tracking well down into record territory. And here’s what the anomaly for August as a whole looks like:


Reactions to the record-breaking melt around the denialist echo chamber have been tracking my projections rather nicely. I’ll have a roundup when the final accounting of the new record minimum is done. For further reading, check out Fen Montaigne’s article on Arctic tipping points for e360, David Spratt’s summary of the state of play at Climate Code Red and a similar overview from New Scientist, Dana Nucitelli at Skeptical Science with the perfect image that demonstrates why the late 30s were not the same as today, and Gwynne Dyer on the possible consequences. For my views on the ice, the winter, peach trees and The Aviator, Alex Smith interviewed me for his Radio Ecoshock show – embedded below…

[Update 6/9/12] The NSIDC has released its Sea Ice News summary of the August melt:

Following the new record low recorded on August 26, Arctic sea ice extent continued to drop and is now below 4.00 million square kilometers (1.54 million square miles). Compared to September conditions in the 1980s and 1990s, this represents a 45% reduction in the area of the Arctic covered by sea ice. At least one more week likely remains in the melt season.
