Fall Arctic Ice Falling Too

The NSIDC Arctic sea ice extent graph has been tracking with the 2007 graph all year. Occasionally it has popped lower to set a new record low. That appears to be happening again now, with ice growth flattening since Thursday to track slightly below the record from 2006. Fall had been the one season in which Arctic ice extent was only modestly lower than the historical record, but now fall too is opening up a conspicuous gap from its pre-2000 record.
