Where, oh where have the hurricanes gone?


Remember hurricane Katrina? The moment that big one hit the U.S. the doomsayers in the global warming movement said it was all about global warming. Well known alarmist Kevin Trenberth warned: "Computer models also suggest a shift in hurricane intensities toward extreme hurricanes." Trenberth, who was the main editor on hurricanes for the IPCC, wanted opponents of his theory left unpublished. He knew in his heart that hurricanes were increasing in frequency and intensity. Now, he did admit that this was true "even if this increase cannot yet be proven with a formal statistical test."

Trenberth wrote in Science, that during 2004 "an unprecedented four hurricanes hit Florida... Some scientists say that this increase is related to global warming; others say it is not." "Thus, although variability is large, trends associated with human influences are evident in the environment in which hurricanes form, and our physical understanding suggests that the intensity of and rainfalls from hurricanes are probably increasing, even if this increase cannot yet be proven with a formal statistical test. Model results suggest a shift in hurricane intensities toward extreme hurricanes."

Time Magazine ran a story headlined "Is Global Warming Fueling Katrina?" Ross Belbspan, in the Boston Globe wrote that while the hurricane "was nicknamed Katrina by the National Weather Service. Its real name is global warming."

Hurricane Katrina was born August 23, 2005. It has been six years since the media was assuring us that global warming was driving hurricanes to greater intensities and frequency. According to the BBC, "The IPCC 2007 report claimed that global warming was leading to an increase in extreme weather, such as hurricanes and floods." They also noted that the IPCC reported was "based on an unpublished reprot which had not been subject to scientific scrutiny—indeed several experts warned the IPCC not to rely on it." The IPCC used the report because it substantiated the entire theory on which their very existence relies.

And, a new hurricane record is about to be set—but not the kind of record you would expect from the dire warnings. The last major hurricane to hit the United States was Wilma which was formed on October 15, 2005. Since then there have no large hurricanes (categories 3, 4, 5) to hit the United States. This record will be 2,232 days from the last major U.S. hurricane. The previous record was a period between September 8, 1900 and October 19, 1906. So this record means we have just gone through a period of the least amount of severe hurricanes since a century ago.

Roger Pielke, Jr. notes that the chances of an intense hurricane before next summer is practically zero, since hurricane season won't start until then. And he says it appears "the days between intense hurricane landfalls [are] likely to exceed 2,500 days." Of course, there is a decent chance that no severe hurricane will hit in 2012 either. But, we can't know until the winter of 2012. What we do know is that we have just gone through a period of the least intense hurricane activity in the memory of anyone alive on the planet today.
