Ad argumentum, let us assume that the IPCC is correct in finding that a warming of 3.26 ± 0.69 K (5.9 ± 1.2 F°: IPCC, 2007, ch.10, box 10.2) might occur at CO2 doubling. We generalize this central prediction, deriving a simple equation to tell us how much warming the IPCC would predict for any given change in CO2 concentration.

ΔTS ≈ (8.5 ± 1.8) ln(C/Co) F°

Thus, the change in surface temperature in Fahrenheit degrees, as predicted by the IPCC, would be 6.7 to 10.3 (with a central estimate of 8.5) times the logarithm of the proportionate increase in CO2 concentration. We check the equation by using it to work out the warming the IPCC would predict at CO2 doubling: 8.5 ln 2 ≈ 5.9 F°.

Using this equation, we can determine just how much “global warming” would be forestalled if the entire world were to shut down its economies and emit no carbon dioxide at all for an entire year. The atmospheric concentration of CO2 is 388 parts per million by volume. Our emissions of 30 bn tons of CO2 a year are causing this concentration to rise at 2 ppmv/year, and this ratio of 15 bn tons of emissions to each additional ppmv of CO2 concentration has remained constant for 30 years.

Then the “global warming” that we might forestall if we shut down the entire global carbon economy for a full year would be 8.5 ln[(388+2)/388] = 0.044 F°. At that rate, almost a quarter of a century of global zero-carbon activity would be needed in order to forestall just one Fahrenheit degree of “global warming.”

Two conclusions ineluctably follow. First, it would be orders of magnitude more cost-effective to adapt to any “global warming” that might occur than to try to prevent it from occurring by trying to tax or regulate emissions of carbon dioxide in any way.

Secondly, there is no hurry. Even after 23 years doing nothing to address the imagined problem, and even if the IPCC has not exaggerated CO2’s warming effect fourfold, the world will be just 1 F° warmer than it is today. If the IPCC has exaggerated fourfold, the world can do nothing for almost a century before global temperature rises by 1 F°.

Oh, the argument is even simpler. She claims global warming is a national security threat. There's an even bigger one: An economic collapse brought on by these idiots' stupid policies like cap and trade.

We're already heading toward a depression if they keep this up. Global warming isn't going to start wars, These deranged kleptocrats and their lunatic laws are a much bigger threat to this country's well being.

“Dumber than a box of Boxers,” as they say.
