I do think that climate change is occurring, that it is man-caused. One of the proposals that I think is a very libertarian proposal, and I'm just open to this, is taxing carbon emission that may have the result of being self-regulating. ... The market will take care of it. I mean, when you look at it from the standpoint of better results, and actually less money to achieve those results, that's what is being professed by a carbon tax. ... Coal is a great free market example right now. You and I do not want carbon emission. We don't want it. right now. Natural gas costs less than coal. So there are no new coal plants that are going to be built, given the price of natural gas. And that's something that you and I desire. So it's happening. I'm afraid that coal, from a free market standpoint, has been done in.
