http://www.globalwarming.org/article.php?uid=286" Drought Cycles and Hurricane Cycles University of New Mexico scientist Louis Scuderi, studying tree ring data in New Mexico, Arizona, Utah, and Colorado, has identified a 72 year drought cycle in the region according to an AP article of April 29th. The last such drought occurred in the 1950s, leading Scuderi to believe that another is imminent in the 2020s.
Although the cause of the drought cycle is still unknown, a good bet would be climactic oscillators, similar to the El Niño and La Niña effects, only operating over this longer timespan. Scientists believe that many of these oscillators may exist, effecting temperature and climate significantly. Naturally, the longer the period of an oscillator, the more difficult it is to detect.
According to hurricane expert Dr. William Gray at Colorado State University, we should see an increase in storm activity over the next 20 years. The storms are expected to cause 5 to 10 times the amount of damage on the Gulf and Atlantic Coasts than previously experienced, due to the massive increase in population and development along these coastlines.
The hurricane activity of the next 20 years should resemble the period that began in the late 1920s and lasted through the 1940s. The increase is due to higher salinity content in the Atlantic Ocean, which alters its currents and increases average ocean temperatures, fueling more storms. Gray emphasizes that this is a cyclical trend and has nothing to do with global warming (CNN, April 22, 2000).'AND "Blackstone begins by acknowledging the warmth of the "noonday sun in New Orleans... unusually warm for this date," conclusive evidence in itself, no doubt. His interviewee is James Baker, administrator of NOAA and reknowned global warming enthusiast. According to Baker, "The January, February, March temperatures in the United States are the warmest ever in our 106 years of record keeping" which "is a very significant fact. It's a wake-up call, really."
And what will we be waking up to? "Severe weather damage" and "more floods, more droughts and...hurricanes with more destructive power." Sounds ominous until, of course, one considers recent insurance industry reports, by Swiss Re and others, discrediting the idea of increased weather extremes while blaming more-costly development for rising storm damages.
Baker, though, prepares himself for the worst: "If you had a Category 4 hurricane that hit New Orleans...you’d have 20 feet of water in New Orleans. That’s frightening." Indeed, Mr. Baker, it is, which is why all should be reassured that it's extremely unlikely.Sounds like a good time to move away from a coastal area, and definately away from the Gulf and Florida Coasts.
