But just because hurricanes are a problem even without considering GW doesn't warrant the conclusion that GW effects on hurricane intensity need not be considered, or communicated to the public.

Yes, most of the increase 1970 - 2004 has been category 4 storms, but of course 2005 set the record for the number of category 5 storms, and records on hurricane intensity and duration are being set in the pacific this season.

Kevin Trenberth, the head of climate analysis at the National Center for Atmospheric Research (NCAR), believes the new study's main finding is accurate, but thinks the effects of some of the environmental factors on hurricane intensity might have been underestimated.

The NCEP / NCAR Reanalysis is the database the researchers drew upon for information about the effects of troposphere humidity, wind shear and zonal stretching deformation on hurricane intensity; sea surface temperature data came from a different database.

But it appears that aerosol effects on hurricane intensity are disproportionately stronger than their effects on the climate overall, because they reduce incoming sunlight while greenhouse gases act through longwave (infrared) terrestrial radiation, and changes in sunlight have a bigger influence on tropical cyclone intensity than changes in infrared radiation do.

And consider this: even if we simply assume that greenhouse gases have a large and immediate impact on hurricane intensities, there is little that mitigation efforts can do anyway to stem the ever - growing economic toll associated with hurricanes.

Such effects on mid-latitude storms, however, seem to be more uncertain than the effects on hurricane intensity and frequency.

This coupling of the atmosphere with the ocean enables the model to reproduce the cooling of the ocean surface beneath the hurricane, which has an important impact on hurricane intensity.
