Baseline Comparison Map

Annual Average Global Temperatures. Both panels are calculated using a 1951-80 periodand represent the average Global Temperature index in degrees C. At the poles where ice cover variesover the record we provide two cases. For the baseline case the air temperature over iceis used for the average and in the alternative case in the bottom panel Sea Temperature under the ice cover is used. -1.8 C is used for this value in all cases

Sea and Ice Comparison - 1950

Comparison of the baseline method with the alternative method. At the poles where ice cover variesover the record we provide two cases. For the baseline case the air temperature over iceis used for the average and in the alternative case Sea Temperature under the ice cover is used. -1.8 C is used for this value in all cases. 1950-present is shown.
