In today’s edition of TechCentralStation (a site for which this author writes regularly), James Glassman, who lived in New Orleans for several years and has strong ties to the community (including family members living there), writes about the efforts of some writers and public advocates to tie Hurricane Katrina to their political agenda:
[T]he response of environmental extremists fills me with what only can be called disgust. They have decided to exploit the death and devastation to win support for the failed Kyoto Protocol, which requires massive cutbacks in energy use to reduce, by a few tenths of a degree, surface warming projected 100 years from now.
Katrina has nothing to do with global warming. Nothing. It has everything to do with the immense forces of nature that have been unleashed many, many times before and the inability of humans, even the most brilliant engineers, to tame these forces.
After recounting some of the activists’ statements, which have received much attention in the news, Glassman addresses their claims directly:
The Kyoto advocates point to warmer ocean temperatures, but they ought to read their own favorite newspaper, The New York Times, which reported yesterday:
“Because hurricanes form over warm ocean water, it is easy to assume that the recent rise in their number and ferocity is because of global warming. But that is not the case, scientists say. Instead, the severity of hurricane seasons changes with cycles of temperatures of several decades in the Atlantic Ocean. The recent onslaught ‘is very much natural,’ said William M. Gray, a professor of atmospheric science at Colorado State University who issues forecasts for the hurricane season.’”
Finally, Glassman points out that the very premise that tropical storms are increasing in intensity is entirely unsupported:
[T]here is no evidence that hurricanes are intensifying anyway. For the North Atlantic as a whole, according to the United Nations Environment Programme of the World Meteorological Organization: “Reliable data…since the 1940s indicate that the peak strength of the strongest hurricanes has not changed, and the mean maximum intensity of all hurricanes has decreased.”
Not only has the intensity of hurricanes fallen, but, as George H. Taylor, the state climatologist of Oregon has pointed out, so has the frequency of hailstorms in the U.S. (see Changnon and Changnon) and cyclones throughout the world (Gulev, et al.).
