Study says global warming not worsening hurricanes
WASHINGTON (AP) — Global warming isn’t to blame for the recent jump in hurricanes in the Atlantic, concludes a study by a prominent federal scientist whose position has shifted on the subject.
Not only that, warmer temperatures will actually reduce the number of hurricanes in the Atlantic and those making landfall, research meteorologist Tom Knutson reported in a study released Sunday.
In the past, Knutson has raised concerns about the effects of climate change on storms. His new paper has the potential to heat up a simmering debate among meteorologists about current and future effects of global warming in the Atlantic.
Ever since Hurricane Katrina in 2005, hurricanes have often been seen as a symbol of global warming’s wrath. Many climate change experts have tied the rise of hurricanes in recent years to global warming and hotter waters that fuel them.
Another group of experts, those who study hurricanes and who are more often skeptical about global warming, say there is no link. They attribute the recent increase to a natural multi-decade cycle.
What makes this study different is Knutson, a meteorologist with the National Oceanic and Atmospheric Administration’s fluid dynamics lab in Princeton, N.J.
He has warned about the harmful effects of climate change and has even complained in the past about being censored by the Bush administration on past studies on the dangers of global warming.
He said his new study, based on a computer model, argues “against the notion that we’ve already seen a really dramatic increase in Atlantic hurricane activity resulting from greenhouse warming.”
The study, published online Sunday in the journal Nature Geoscience, predicts that by the end of the century the number of hurricanes in the Atlantic will fall by 18 percent.
The complete story is here.
This echoes what I reported on April 11th 2008 about Emanuel’s findings as well as what I reported on February 21st 2008 from Roger Pielke Jr. and Chris Landsea at the National Hurricane Center.
Three prominent researchers agree, two have reversed positions. This I think it is safe to declare the “Increased hurricanes to global warming link” as DEAD.
So two questions remain:
1) Will Al Gore issue a retraction or correction to his movie and claims of a GW to hurricane link?
2) Will the American Meteorological Society abandon their draft policy statement which links Hurricane Katrina and climate?
It would be irresponsible for either Gore or AMS not to acknowledge this sea change in the realization that there is no linkage between global warming and increased hurricane frequency.
Dr. Bill Gray must be a happy man today.
