In a recent post I showed that the enthusiasts for a carbon tax are really getting desperate, with people such as Paul Krugman now using rhetoric that he himself considered cringe-worthy back in 2009. Specifically, the pro-carbon tax crowd is shifting the emphasis away from climate change—which remember, was itself the new term to replace “global warming”—and towards things like reducing respiratory problems for people who live near coal-fired power plants. The pro-carbon tax crowd is focusing much of its attention on “particulate matter” or “PM” concentrations, and the alleged benefits from reducing PM are now considered a majority share of the total benefits of a carbon tax.
