FOR the better part of a decade, I have upset many climate activists by pointing out that there are far better ways to stop global warming than trying to persuade governments to force or bribe citizens into slashing their reliance on fuels that emit carbon dioxide.
What especially bugs my critics is the idea that cutting carbon would cost far more than the problem it is meant to solve.
"How can that be true?" they ask. "We are talking about the end of the world. What could be worse or more costly than that?"
They have a point. If we actually face, as Al Gore recently put it, "an unimaginable calamity requiring large-scale preventative measures to protect human civilisation as we know it", then no price would be too high to stop global warming. But are the stakes really that high?
The answer is no.
