The Oceans Role in Greenland and the Arctic Region Temperatures and Ice

By Joe D’Aleo, Icecap

In the prior blog, we showed how multidecadal ocean cycles were playing a role in temperature swings over the past 110 years and could be used to explain much of the variance. In the attached brief paper, I show how the same can be said for Greenland and the Arctic where these factors play a far more convincing role in the observed changes than greenhouse gases.  This was confirmed in a June 2006 GRL paper Greenland Warming of 1920-1930 and 1995-2005 by Chylek etal.  See Greenland Warming

Image above shows Greenland Annual Temperatures since 1880 at Godthab Nuuk (top) vs the Atlantic Multicdecadal Oscillation (bottom). For full aize images see pdf.

Arctic Basin-wide Annual Mean Temperatures (Polyakov) likewise follow the ocean multidecadal cycles
