Arctic Temperatures Continue Rapid Rise as 2011 Breaks Record Set in 2010
NASA yesterday (19 January 2012) released data showing that last year temperatures in the Arctic rose beyond the record established in 2010 -- setting a new record for 2011. News of the record Arctic temperatures follows a series of alarming developments related to the Arctic in recent months.
The surface temperature anomaly for the region extending from 64°N to 90°N, from 1880 through 2011, in degrees Celsius above or below the temperature during the 1951-1980 base period. The figures shows that temperatures have risen substantially since 1880 and that the rate of increase has been especially rapid since the late 1970s.

According to NASA's Goddard Institute for Space Studies (GISS), the annual mean surface temperature (land and air) for the region north of 64°N (the Arctic Circle is at 66° 33'N) in 2011 was 2.28°C above that which characterized the 1951-1980 period. Temperatures in the region have been rising rapidly since the late 1970s and have not dropped below the long term mean since 1992 -- nearly 20 years. This year's annual mean temperature broke the record that was just set in 2010, when the temperature was 2.11°C above 1951-1980 levels.
