Enough with the doomsday proselytizing of the Church of Global Warming. So much time and effort has been spent selling the idea that our reliance on fossil fuels is causing a planetary catastrophe that no one is asking the really important questions: If the world goes cold turkey on oil and coal, will anything change, and how much will it cost?

Demand for energy will only rise in the decades and centuries ahead, so the resources needed to power our automobiles (even ones that run on batteries) and our air-conditioners in a warmer future has to come from somewhere. Replacing every internal-combustion engine, every oil refinery and every coal-fired power plant with energy sources that do not emit carbon would cost trillions of dollars.

That's a politically impossible price tag, especially for nothing more than a theory that higher temperatures might do more harm than good.
