Recently Walt Meier posted about artic sea ice 2010 on WUWT. Good for Anthony for giving Dr. Meier the podium. Meier emphasized that the state of arctic sea ice has changed dramatically. Referring to predictions of this year’s summer minimum in arctic sea ice extent:
The first thing to point out is that none of the estimates approached the 1979-2000 monthly September average of 7.0 million square kilometers. Even the highest estimates were nearly 20% lower. This is a recognition that conditions have clearly changed since the 1980s and 1990s. It is no longer plausible to prognosticate anything near average levels.
So: things have changed.
