Katrina and Disgusting Exploitation
...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.

But that doesn't stop an enviro-predator like Robert F. Kennedy Jr. from writing on the Huffingtonpost website: "Now we are all learning what it's like to reap the whirlwind of fossil fuel dependence which Barbour and his cronies have encouraged. Our destructive addiction has given us a catastrophic war in the Middle East and - now -- Katrina is giving our nation a glimpse of the climate chaos we are bequeathing our children."...

...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.'"

An article on TCS quoted Gray last year as saying that, while some groups and individuals say that hurricane activity lately "may be in some way related to the effects of increased man-made greenhouse gases such as carbon dioxide,…there is no reasonable scientific way that such an interpretation…can be made."

Indeed, there 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."

Yes, decreased....
