Climate scientist writes "my global warming skepticism, for dummies"

Dr Ray from Greenie Watch http://antigreen.blogspot.com/ writes:

Prof. Spencer is an eminent climate scientist and points out many reasons why the case for human emissions causing warming is at least "not proven". He has however always in the past accepted the theory that CO2 COULD cause warming. A recent upwelling of dissent on that point by physical scientists has however obviously jarred him so you will see from the rubric below (under his "7" heading) that he is now reserving judgment on that point. He is leaving open the possibility that the whole theory was misconceived from the beginning and in fact contravenes the laws of physics.

Good heavens, this almost seems a step too far for even me. Could we have got the whole thing about the greenhouse effect wrong (or at least partly so)?
