...idea that there might be fewer Atlantic hurricanes in a warming world is not a new one. Earlier studies led by Thomas Knutson of the National Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics Laboratory (GFDL), a co-author of this week's Science paper, had reached the same conclusion. The explanation for this seemingly paradoxical finding: hurricane activity is governed not only by ocean temperatures, but also by factors such as ocean currents and the speed and direction of wind in different layers of atmosphere. It turns out, says Knutson, that the key to hurricane frequency is not simply...
...authors warn that their findings, while important, are not the final word and must be validated by others. Bender, Knutson and their colleagues ran the simulation using an average of 18 climate models at once, then reran it with four models individually. One of the models, Bender says, showed a decrease in the most powerful storms, demonstrating once again that the effects of climate change are complex and not easily predicted...
...June issue of the journal Nature Geoscience, Tom Knutson of the National Oceanic & Atmospheric Administration questions whether we're seeing "a really dramatic increase in Atlantic hurricane activity resulting from greenhouse warming." Quite a few of Knutson's colleagues in turn are questioning him and the computer models he's using to make this about-face. But for those of us who aren't in the eye of that scientific storm, it only raises the issue of whether predicting hurricanes is really any more reliable than forecasting earthquakes...

...Knutson agreed, saying that Barman’s analysis appears to account for some, but not all, of the color-dependent features in the data that she and Charbonneau collected from the Hubble Space Telescope last year...
