The results don't sit well with the man-caused-global-warming brayers who want you not to question their contention that warmer ocean waters must mean more severe hurricanes.</p><p>Hiding the problem, the <em>Washington Post</em> simply buried the study's results under the headline, "Ocean Temperatures Not the Only Determining Factor in Hurricanes" and played up the brayers' line as though there is science to back it up.</p><p>What the Woods Hole study showed, according to a May 23 WHOI release, is that it is the El Nino/Southern Oscillation and the West African Monsoon that are the key determiners of hurricanes. The researchers found that the number of intense hurricanes increased when El Nino was relatively weak, and the West African monsoon was strong.</p><p>"Much media attention has been focused recently on the importance of warmer ocean waters as the dominant factor controlling the frequency and intensity of hurricanes. And indeed, warmer sea surface temperatures provide more fuel for the formation of tropical cyclones," the WHOI release noted. "But the work by [Jeff] Donnelly and [Jonathan] Woodruff suggests that El Nino and the West African monsoon appear to be critical factors for determining long-term cycles of hurricane intensity in the Atlantic."</p><p>The two geologists began their study in 2003 by sediment-core samples from Laguna Playa Grande on Viegues (Puerto Rico), an island extremely vulnerable to hurricanes. The geological record showed that there were periods of more frequent intense hurricanes from 5,000 to 3,600 years ago, from 2,500 to 1,000 years ago, and from 1700 AD to the present. Previous records from New York and the Gulf Coast matched those findings. The study's latest results are in the May 24 issue of <em>Nature</em> .</p></div></body>
