Hmm, you bring a convincing argument, then again, Stewie is a super genius British Spy stuck is a 2 year old's body...

Either way, I agree with Bob. Just because science, as we now know it, doesn't think the climate shift would occur that quickly doesn't mean it won't. Who knows, for all we know, the hydrogen bomb equivalent of napalm could be invented and fired at the ice caps, causing the instant melting the way Acer (I think it was Acer) was asking about the Sun instantly melting them. There are so many unseen circumstances that could occur that we have no idea about. It's not out of the question, just about 87.315% out of the question.
