Bluff calling

I'm just off out to the school board meeting, but before I go here's an ingenious solution to global warming, penned by Ross McKitrick, an economist at the University of Guelph. 

Both warmers and skeptics agree that if there is going to be any warming it will be seen first in the troposphere. Because of this consensus (a real consensus this time) a tax on carbon, linked to the temperature of the troposphere should be supported by both sides of the debate. The tax would initially be quite low. But if the temperature rises, as predicted by the warmers, then the tax goes up. If it falls, or is stable, which is what the skeptics think might happen, then the tax remains relatively trivial.

A rather neat idea, in that it calls the bluff of both sides.
