Hurricanes Not Linked To Global Warming

Expert disputes storms' link to global warming

Chris Landsea, science and operations director of the National Hurricane Center in Miami, said the notion that global warming is causing an increase in hurricanes gained widespread attention after the stormy seasons of 2004 and 2005.

But that perception is wrong and the statistics don't bear it out, Landsea told about 200 students and professors in the auditorium at USC's geography building.

Further study continues to show that hurricane activity occurs in cycles of 20 to 45 years, he said. Even though the seasons of 2004, when four hurricanes bashed Florida, and 2005, when Katrina devastated New Orleans and neighboring parts of the Gulf Coast, seemed shocking, they were no more intense than some storms in the early part of the 20th century and in the 1930s, Landsea said.
