Maybe I should clarify this part:

I think it would be hard to convince me one way or another that a link between human activity and climate change either exists or does not exist. I believe a link (maybe even a strong one) is possible, but I don't think it's possible to demonstrate a clear cause and effect link, because climate is completely chaotic and unpredictable.
In fact I would broaden my position to state that I don't think a clear cause and effect can be proven between any specific factor and climate. If we were able to build a true understanding of what in fact influences climate (and weather! perhaps more to the point), we would be able to do a (much) better job at predicting it.
