“Research into hurricanes in the North Atlantic indirectly suggests that the last 100 years in Australia have been relatively wet. Forget about Greenhouse. Just the normal swings and roundabouts of the climate have the potential to be devastating…
Graham Young writing at his blog Ambit Gambit goes onto suggest that based on a recent paper in Nature entitled ‘Intense hurricane activity over the past 5,000 years controlled by El Nino and the West African monsoon’ governments might consider “spending more taxpayer monies reconstructing paleo-climate, and less modelling future climate scenarios.”
He also comments, “What’s more, in a challenge to vulgar Greenhouse assumptions, there appear to have been more severe hurricanes in the past than the ones we’ve seen recently, even though the sea was colder then.”
The paper in Nature is worth a read: http://ff.org/centers/csspp/library/co2weekly/20070525/20070525_02.pdf
