Well, again... on the one hand we have the expertise of the vast majority of the world's most qualified scientists; on the other hand we have the 'expertise' of the usual online suspects, the conspiracy freaks who insist that all those conniving scientists are out to mug them for grant money. Not a difficult choice, between such opposing views, for a mature and rational adult to make -- not for one who cares about something bigger than his own material ease, namely the future and its new generations. 
And clearly most governments are moving to ameliorate climate change, better late than never, leaving the denying types to their feeble protests and increasing frustration. Looks good on 'em.
