The media has been having a prolonged belly laugh at a group that had the temerity to suggest that the world would end today. Of course it's ridiculous when Harold Camping predicted that the world will be over today, but not when Al Gore predicted that the North Pole would melt in five years. True believers in Gore would say that's the difference between science and eschatology. But when bogus science warns us of an apocalypse if we don't follow the tenets of their ideology, then how much difference is there anyway?
