UPDATE: Antarctica Set An All Time Record For Sea Ice Extent on Sept 14th. Read about it here.
David Rose is getting a lot of hate for telling the truth about shoddy climate models.
But this quote from the leaked upcoming AR5 jumped out at me:
“‘Most models simulate a small decreasing trend in Antarctic sea ice extent, in contrast to the small increasing trend in observations… There is low confidence in the scientific understanding of the small observed increase in Antarctic sea ice extent.’

Right now the mean for the year for Global Sea Ice Anomaly percent is +0.9% above the 1981-2010 mean.
The anomaly have been over +4% earlier in the year and is now almost -2%.
September 34 (Day 247) saw the 39th Daily Record of the Year for Antarctic Sea Ice Extent.
Antarctic Sea Ice Extent is 19.16 million sq km.
If you add up the number of daily records, 2013 is a distant 3rd behind 2008 and 2010. However, if you also add in 2nd place finishes, 2013 slightly edges out 2010. And 118 days remain in the year.
