I've been saying this all along… the sun is the Big Kahuna of climate change on earth. - Anthony Watts

I would say that the polar ice has disappeared in the past. Certainly there seems to be evidence of past climate situations where we may have had virtually no or none during the summertime. In the immediate future, however, I don't think we are going to see that. In fact, we're going through a rebound right now.

Climate Change Reconsidered, the 2009 report of the Nongovernmental International Panel on Climate Change (NIPCC), is the report on global warming the United Nations' climate panel should have written – but didn't.

When we look at the Anthropogenic Global Warming argument, it seems on the surface that we are completely full of ourselves and yet at the same time terribly dubious, sometimes completely without hope, and utterly given to embracing our own fallibility as a cause célèbre. We show no faith in ourselves by accepting this idea that we’ve caused Global Warming and still none in the idea that we can stop it. These are hollow beliefs put forth to enrich the power of the few whom offer us the way to salvation.
