Arctic getting hot

The now published annual report by the american National Oceanic and Atmospheric Administration (NOAA) claims that the average air-temperature this autumn in the Arctic is 5° higher then the long-term average. The vanishing ice cover provides less reflection and isolation, and the darker seawater adsorbs more radiation. The actually measured ice cover is lesser by 34% to the average from 1979-2003, only 2007 showed a higher value, with 43%.
