A profound tragedy is unfolding in New Orleans... That is why the 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. Giant hurricanes are rare, but they are not new. And they are not increasing. To the contrary. Just go to the website of the National Hurricane Center and check out a table that lists hurricanes by category and decade. The peak for major hurricanes (categories 3,4,5) came in the decades of the 1930s, 1940s and 1950s, when such storms averaged 9 per decade. In the 1960s, there were 6 such storms; in the 1970s, 4; in the 1980s, 5; in the 1990s, 5; and for 2001-04, there were 3. Category 4 and 5 storms were also more prevalent in the past than they are now. As for Category 5 storms, there have been only three since the 1850s: in the decades of the 1930s, 1960s and 1990s.The table he cites that counts hurricanes by intensity by decade that hit the US mainland is at NOAA's National Hurricane Center And the revered New York Times also has the science that does not connect global warming and hurricanes.
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.Let's stick to the science. Hurricanes have decreased, not increased. And their cycle is over long-term ocean temperature cycles.
