THIS IS The #Climate Question
Everything else, is a corollary….
From Bishop Hill’s “Nobel laureate on temperatures” (Feb 2012):
The question is not whether temperatures have risen or whether mankind has affected the climate. Temperatures have always risen and fallen and mankind has always affected the climate. The question is whether we have a problem on our hands. The poor performance of the climate models suggests that the problem is much less than we have been led to believe.
