Gray and Muddy Thinking about Global Warming

Anybody who has followed press reporting on global warming, and particularly on its effects on hurricanes, has surely encountered various contrarian pronouncements by William Gray, of Colorado State University. A meeting paper that Gray provided in advance of the 2006 27th Conference on Hurricanes and Tropical Meteorology (taking place this week in Monterey California, and coverered here by CNN), provides an illuminating window into Gray's thinking on the subject. Our discussion is not a point-by-point rebuttal of Gray's claims; there is far more wrong with the paper than we have the patience to detail. Gray will have plenty of opportunities to hear more about the work's shortcomings if it is ever subjected to the rigors of peer review. Here we will only highlight a few key points which illustrate the fundamental misconceptions on the physics of climate that underlie most of Gray's pronouncements on climate change and its causes.
