Read here. The latest peer-reviewed studies refute climate models based on the AGW hypothesis: the recent global warming has not caused an increase in severe tropical cyclones. In fact, cyclone activity is basically flat despite the huge increase in human CO2 emissions. In addition, the absolute latest models are now predicting reduced cyclone events if it continues to warm - read the linked article. Obviously, there is no "consensus" among the IPCC 2007 climate models and more recent models. (click on image to enlarge)
"Kuleshov et al. gathered tropical cyclone data for the Southern Hemisphere (SH), the South Indian Ocean (SIO), the South Pacific Ocean (SPO), and the Australian Region (AR). They defined a tropical cyclone as “a tropical system that attains minimum central pressure of 995 hPa or lower.” They also defined severe tropical cyclones as those that attain a minimum central pressure of 970 hPA.....there are simply no trends in their data, and the authors conclude “For the 1981–1982 to 2006–2007 period, there are no apparent trends in the total numbers of TCs reaching minimum central pressures of 995 hPa or lower, nor in the numbers of severe TCs in the five subdomains of the SH examined”. Once again, a study appears in a major journal showing no trend whatsoever in hurricane activity."
