"A letter to the editor of the Wall Street Journal from distinguished Professor of Physics at Princeton University William Happer is published today in which he states, "Even if we could hold CO2 levels fixed, the climate would continue to change because of other influences. In a time of serious world problems, wasteful expenditures justified by nonproblems like CO2 make no sense."
