Well, there is a chance that the new up coming global ice age (Why is humanity so obsesed with their doom?) could balance out global warming, unless, as Alan Gore states, global warming triggers the next iceage, in which we get a bit of both, and are screwed, which we already are.
But has anyone seriously considered seeking out a livable planet, and abandoning earth?
I mean, like the entire population evacuating earth, gradually, when a disaster is about to strike.
