Many scientists predict -- shockingly -- that the entire North Polar ice cap may be completely gone during summer months during the first term of the next president.
Using ever fancier technologies, the oil business is drilling in deeper waters, more difficult terrain and even in the Arctic (which, as global warming melts the polar ice cap, will perversely become the next great prize in oil).
Jack Hall (Dennis Quaid) is a climatologist who realizes, as a slice of the polar ice cap slides into the sea, that the end of the world (or, at any rate, of that half of the world that drives S.U.V.s) is nigh.
The shape of the polar cap indicates that it is composed primarily of water ice, with a volume of 1.2 million cubic kilometres.
But the volume of the Martian north polar cap is less than half that of the Greenland ice cap, and about four percent of the Antarctic ice sheet.
