The New York Times’ review of Brian Doherty’s history of libertarianism, Radicals for Capitalism, says that the Cato institute (and, implicitly, other libertarians) is “struggling to persuade people that global warming… is a hoax.” Except, of course, that, as David Boaz notes, Cato isn’t saying that. Liberals often accuse conservatives and libertarians of being stuck in the past on global warming, but these days, it’s liberals who’re behind the times. The debate these days isn’t nearly so much about whether global warming is happening (although there is still disagreement over what factors contribute to it), it’s whether or not it will be catastrophic, and what we can and should do about it with regards to public policy.
