You do realise that you have to add NASA and the Pentagon to the list of liberal lefty organisations that believe in AGW?That depends whose data you use, climatologists' or Big Oil's.The data doesnt completely support us alone being the cuase.
Basically there are two possible scenarios. (Three if you count the one that says nothing is changing, and all the stuff about melting icecaps, rising temperatures etc, is a fraud by the international communist conspiracy who've suborned all the meteorologists, naturalists and geographers in the world.)
Either the world is warming for simple physically explicable reasons which are theoretically controlable, so we could survive if we have the guts to do what's necessary.
Or the world is warming for some mysterious reason (which by a strange coincidence began when we started burning vast amounts of fossil fuels and wiping out forests) which nobody can explain or do anything about, and we might as well live it up, drive our SUVs and turn up the heating, because we're doomed anyway.
Even if the science didn't convince me, I am not a natural fatalist. We may not be able to save ourselves, but I'll always want to go down trying.
