Arctic Report Card – Update for 2012: “The Arctic region continued to break records in 2012—among them the loss of summer sea ice, spring snow cover, and melting of the Greenland ice sheet. This was true even though air temperatures in the Arctic were unremarkable relative to the last decade, according to a new report released today. ..New records set for snow extent, sea ice extent and ice sheet surface melting, despite air temperatures – a key cause of melting – being unremarkable relative to the last decade. Multiple observations provide strong evidence of widespread, sustained change driving Arctic environmental system into new state.”
