Arctic sea ice extent set a new record low at the end of the summer melt season on September 16, 2012. But extent is not the only quality of the ice that is changing. Wind and ocean circulation patterns are conspiring with a warmer climate to reduce the amount of year-round (multi-year) ice, transforming the remaining ice into a younger, thinner version of its old self.

Arctic sea ice extent fell to 1.58 million square miles on August 26, 2012. This was 27,000 square miles smaller than the previous record low of 1.61 million square miles set in 2007.

A series of unusually strong, long-lasting high pressure systems has parked over Greenland this summer.
