The references below add up to an expectation that by 2100 the polar ice caps will be gone, that the polar ice mass will be redistributed in the oceans, that the reslting unbalance will cause the earth’s crust to shift dramatically. The result would be that we all move whether we want to or not, and experience a shift both in local time and latitude. What do you think of this?

“In a polar region there is a continual deposition of ice, which is not symmetrically distributed about the pole. The earth’s rotation acts on these unsymmetrically deposited masses [of ice], and produces centrifugal momentum that is transmitted to the rigid crust of the earth. The constantly increasing centrifugal momentum produced in this way will, when it has reached a certain point, produce a movement of the earth’s crust over the rest of the earth’s body, and this will displace the polar regions toward the equator.”

If today 's warming continues and deep-sea temperatures cross the threshold at which methane hydrates melt, huge amounts of methane could be released, triggering drastic global warming. It isn 't known how likely this is, but researchers have shown that something similar happened at the end of the Palaeocene epoch. Fifty-five million years ago, a gradual warming of the oceans preceded a dramatic shift in carbon isotope ratios and a steep jump in water temperatures - precisely the pattern expected if gradual warming melted the hydrate reserves. Looking at what happened in the Palaeocene helps to answer two crucial questions : how much of the methane can be released at once, and how that would affect climate.

By studying the carcasses of the woolly mammoth and rhino found in the northern regions of Siberia and Canada one can see the land these animals gazed on was suddenly shoved into a much colder climate. Their stomachs reveal food found in warm climates where they grazed just prior to their deaths. This was found frozen along with them suddenly.
Thousands of animals were found to be frozen in a brief moment of geological time. Ancient maps of Antarctica suggests that it too was ‘frozen over’ in a brief moment in time.
It has been suggested that approximately 12,000 years ago there was a displacement of the Earth’s crust. The entire outer shell of the earth moved approximately 2,000 miles. When the Earth’s crust shifted all of Antarctica was encapsulated by the polar zone. At the same time North American was released from the Arctic Circle and became temperate.

.) while the other theory: something similar to the methane gas thing you mentioned, in that the earth has a natural cooling and heating of elements that goes on periodically over thousands of years in some equalibruim.
