I think that Climate Change got silly when it changed from a Science to an Industry. I think it is certainly something to be concerned about, but it's been over-politicised to an almost hysterical level, we laugh at the Rapturers and the Nibiru supporters, and yet allow ourselves to be pulled into the same trap at times. Admittedly, Climate Change is something a bit different to the Nibiru crap, there's testable evidence for the former, but the interpretation of those tests count for a lot.
Personally, however, I think that trying to stop Climate Change is like pissing into the Ocean, we've evidence that any Ecological balance on Earth is only maintained for a limited time before shifting, be it Ice Ages, Dry Spells or even atmospheric composition, it all all shifts with time, the question of human influence is more about 'how much' than anything else and in the long term is a moot point.
