UPDATE 2: And Another.
UPDATE: Another record.
Antarctic Sea Ice Extent set a record on day 43 (Feb 12 2013) for most ever on this day. at 3.80037 million sq km.
The old record was in 2008. The record for most ice ever at minimum was also in 2008. 3.69176 million sq km. There is a decent chance that record will be broken.
