Noordpoolijs smelt naar nieuw laagterecord
September 20, 2012 - Arctic sea ice has melted to its lowest level this year, setting a record for the lowest summer cover since satellite data collection began 33 years ago. The record was broken on August 26, when the ice shrank below the record set in 2007. After that, it kept melting for three more weeks, bringing the ice extent to nearly half of the 1979-2000 average.
