On March 4, David Frum, a former special assistant to President George W. Bush, published an article on CNN.com titled "Peak Oil doomsayers proved wrong" in which he not only claimed there was no danger of a shortage of oil, but also that "our oil problem is that we’re producing so much of the stuff that we are changing the planet’s climate." Mr. Frum is only the most recent contributor to a growing list of luminaries to declare that we need not worry about any future shortage of crude oil. The only problem with these reassuring proclamations is that the physical evidence does not support them, and does in point of fact, warn of a looming imbalance between supply and demand with troubling implications for the U.S. economy.
