New paper shows Greenland was warmer during the 1930’s and 1400’s than the present

The Hockey Schtick

A new paper published in Climate of the Past reconstructs Greenland temperatures over the past 800 years and shows that reconstructed temperatures were higher in the 1930’s and 1400’s than at the end of the record in the year 2000. The paper also finds Greenland temperatures correlated to “solar-induced changes in atmospheric circulation patterns such as those produced by the North Atlantic Oscillation/Arctic Oscillation (NAO/AO).” The Medieval Warming Period 1000 years ago is not included in this 800 year reconstruction, but Greenland ice cores demonstrate that the Medieval, Roman, Minoan, Egyptian, and other unnamed warming periods were all warmer than modern Greenland temperatures.

Reconstructed Greenland temperatures shown in blue bottom graph were higher in the 1930’s and 1400’s than at the end of the record in the year 2000. Michael Mann’s bogus hockey stick is shown for comparison in green in top graph.
