The Arctic region continued to break records in 2012 - among them, the loss of summer sea ice, late spring snow cover, and melting of the Greenland ice sheet - as the region settles into a new state. This was true even though air temperatures in the Arctic were unremarkable relative to the last decade.
Major findings include record lows in snow and Arctic sea ice extent, record setting glacier and Greenland ice sheet melt, and greening of the tundra, with varied impacts on marine and terrestrial ecosystems.
