Inventor of Cap-and-Trade Thinks It’s the Wrong Approach to Climate Change « The Washington Independent

But although he devised the idea, [Thomas] Crocker said in an interview with The Washington Independent that cap-and-trade is not the best policy to reduce greenhouse gas emissions and, going a step further, raised questions about climate science.

“The economists who have studied this problem, say, ‘Yes, it’s worthwhile taking some measures,’” Crocker said. “But to get into a great big panic and jump overboard right now is really not appropriate.”

Greenhouse gases, Crocker argued, are not as incrementally dangerous as SO2 and other pollutants. Therefore, price certainty, delivered through a carbon tax, is more important.

More broadly, Crocker raised questions about climate science, arguing that the models used by climate scientists are easily manipulated.

“There’s a great deal of ambiguity with respect to the natural science,” he said. “These models that they employ seems to me, they are numerical simulations, and as with any numerical simulation, a great deal depends upon what values you attach to unknown parameters.”
