Derb, Al Gore’s being a little more than merely innumerate when he breezily asserts that the temperature of the earth’s interior is “several million degrees.” His entire, highly lucrative shtick rests on the proposition that a one-degree increase in surface temperature in the course of a century imperils not merely the poor old polar bear, not merely the planet itself, but is “altering the balance of energy between our planet and the rest of the universe.” But he’s so insouciant about “several million degrees” boiling away a couple of miles under his loafers that he can’t even be bothered getting it right to within three figures.

It makes you wonder whether even he believes any of this stuff.
