SeanD,
I had a similar thought, and was going to ask a similar question for Scm, and others with doubts about causes of climate change. For that matter, who could change your mind in the opposite direction, if you are in the human causation camp? Who would you believe, if they stated a position that you don't currently agree with?
Is there any source of information that could change your mind on a strongly held opinion?
