This debate always irritates me, for the simple reason that I shouldn't actually give a flying f*ck. The planet will outlast me and my mrs, and we have no children. And to be honest, I'm not fond enough of any of my relatives to care much about what they have to deal with once we're finished f*cking up the planet for mankind. The people arguing that its all a myth are almost invariably parents, where the hell is the logic in that? Don't they care at all that the human species might, just might, be blighting their descendants lives? Don't they care about them? If I had kids I'd be fuming. Its obvious to anyone looking objectively at the situation that the CO2 we are pumping into the atmosphere may, at some point, lead to a horrific situation for the next generation, or their offspring. Practically every climate scientist seems to agree on this, why argue with scientists who spend their lives studying it? They don't even have to prove it for action to be necessary, just a fraction of a percent of probability is enough, and they've already shown that, in spades redoubled. FFS.
Rant over.
