Arctic Assessment bombshell: "Global sea level is projected to rise by 0.9–1.6 meter by 2100"

The past six years (2005–2010 have been the warmest perio ever recorded in the Arctic Higher surface air temperature are driving changes in the cryosphere. There is evidence that two components of the Arctic cryosphere – snow and sea ice are interacting with the climate system to accelerate warming. The extent and duration of snow cover and sea ice have decreased across the Arctic. Temperatures in the permafrost have risen by up to 2 °C. The southern limit of permafrost has moved northward in Russia and Canada. The largest and most permanent bodies of ice in the Arctic – multiyear sea ice, mountain glaciers, ice caps and the Greenland Ice Sheet – have all been declining faster since 2000 than they did in the previous decade.
