The OP intent was less about climate change and more about the thought processes behind it but because, As Jeff O states (and I am guilty of in my initial response) everyone has an almost religious opinion on it.
Perhaps this may incorporate both the topic and a proper approach to it in that it is from a co-founder of Greenpeace, talking about climate change in a way most would not expect. It can't be the proper approach simply because I agree with the synopsis- and that is what must remain the point.
