Are We Heading for a New Minimum?

The Arctic Sea Ice News and Analysis provide nearly real time (about a 24 hour delay) data on the extent of ice at the poles. After a winter of nearly "normal" (close to the 20 year mean of 1979-2000) ice extent, the spring melt began to pick up speed in May and early June, and the ice extent has already dropped well below the previous record minimum extent of 2007.
