After a new volume record for the PIOMAS model, we now also have a new record in the Cryosphere Today data set. The 2011 trend line had been brushing very close to it a couple of times, going up again, but with a daily area decrease of 58,940 square km for September 6th it has gone below the 2007 record minimum sea ice area set on September 7th 2007 (2,917,493 square km). It is now almost 2000 square km below the record (2,917,439 square km) and might go a little lower still, although the last four years all had their minimum around this date.
