Waiting On Innovation, Ctd

Manzi responds to Millman. He disagrees that a carbon tax would spur innovation:

Why would increasing [gas:] prices in America work when it hasn't for Europe? There might be some
carbon price that would radically accelerate innovation across the
array of uses of fossil fuels ... but it has never, to my knowledge, been imposed
anywhere at scale, presumably because it would impoverish any country
that tried.
