David Wojick, Heartland Institute, Ph.D. Philosophy of Science and Mathematical Logic, B.Sc. Civil Engineering:The climate change debate is not about the basic greenhouse effect. It is about what warming, if any, the increase in atmospheric CO2 concentration might bring and whether or not it is dangerous. Deming addresses none of this, which is certainly simple, but also useless. He simply equates the increased CO2 concentration with global warming. The validity of this equation is what most of the debate is about, but there is no hint of this in his presentation. It is as if the debate did not exist. He even suggests that this entire issue was settled over 100 years ago, which is simply laughable.
