The latest research published in Nature Geoscience says that the rise in hurricane frequency since the mid nineties are just part of a natural cycle called weather. There is evidence of several severe tropical storm cycles, some much worse, prior to the industrial revolution. If man made global warming were indeed “settled science” computer modeling shows there would be a decrease in high category hurricanes.
The cover of Al Gore’s newest book, Our Choice, depicts an artist’s impression of a world beset by a series of huge super-hurricanes as a warning of what might happen if carbon emissions continue to rise.
However, the latest research, just published in Nature Geoscience, paints a very different picture.
It suggests that the rise in hurricane frequency since 1995 was just part of a natural cycle, and that several similar previous increases have been recorded, each followed by a decline.
Looking to the future, it also draws on computer modelling to predict that the most likely impact of global warming will be to decrease the frequency of tropical storms, by up to 34% by 2100.
It does, however, suggest that when tropical storms do occur they could get slightly stronger, with average windspeeds rising by 2-11% by 2100. A storm is termed a hurricane when wind speeds exceed 74mph, but most are much stronger. A category 4 or 5 hurricane such as Katrina generates speeds in excess of 150mph

Argentines Francisco Lotero, 56, and Miriam Coletti, 23, shot their children before killing themselves after making an apparent suicide pact over fears about global warming.
Their son Francisco, two, died instantly after being hit in the back.
