Back in August, I warned that conservatives shouldn’t trust economist Irwin Stelzer when he pushes a carbon tax, because he was confidently telling them “facts” about the economic case that were simply not true. Stelzer is back at again, this time in a year-end post in National Review. Once again, Stelzer tries to convince conservatives that a carbon tax would make economic sense even putting aside issues of global warming. This is utter nonsense, as I’ll explain in this post.
