There are two dangers posed by the idea of anthropogenic global warming:
- Government regulation of greenhouse gases, with the greatest current threat posed by EPA’s plans to use the Clean Air Act to limit carbon dioxide emissions
- Environoiac pressure groups such as Ceres who want to limit fossil fuel usage by everyone in the world
Neither is an actual physical threat posed by the fantasy phenomenon itself, but only by those who believe in it, as I explain today at the National Legal and Policy Center blog.
