So Much for "Settled Science"

It seems Al Gore's claims aren't the slam dunk he claims them to be:

Mathematical proof that there is no “climate crisis” appears today in a major, peer-reviewed paper in Physics and Society, a learned journal of the 10,000-strong American Physical Society, SPPI reports.
Christopher Monckton, who once advised Margaret Thatcher, demonstrates via 30 equations that computer models used by the UN’s climate panel (IPCC) were pre-programmed with overstated values for the three variables whose product is “climate sensitivity” (temperature increase in response to greenhouse-gas increase), resulting in a 500-2000% overstatement of CO2’s effect on temperature in the IPCC’s latest climate assessment report, published in 2007.

Can we at least look into this before we systematically dismantle the economic system that has brought more wealth, health, and comfort to more human beings than ever in the history of mankind?
