The Religious nut jobs that believe that some invisible omnipotent fairy in the sky will solve climate change is delusional. The North Polar icecap is the smallest it's ever been in recorded history, our glaciers are indeed disappearing and even the Peruvians have taken to painting the rocks on their Andes mountains white in the hopes of cooling things down.
That said, I say, let it all go. The sooner humans are roasted off this planet, the better. Hopefully then, the earth just might heal and something better arise through evolutionary adaptation.
