Read here. For decades, AGW alarmists have been predicting an increase of cyclone/hurricane frequency and intensity due to CO2-induced global warming. Unfortunately for the alarmists and IPCC Climategate scientists, the predictions have been hugely wrong.
In another study regarding tropical cyclones, researchers documented the lack of a relationship between warming and cyclone activity.
"The authors analyzed various cyclone characteristics based on four decades of cyclone season data contained in the regional cyclone archive of the tropical South Pacific that is maintained by the Regional Specialized Meteorological Centre (RSMC) located at Nadi in the Fiji Islands...Terry and Gienko state that "no linear trends were revealed in cyclogenesis origins, cyclone duration, track length or track azimuth over the four decades of records,".....In discussing the first of these findings, the two researchers say that the lack of linear trends in the four cyclone parameters they analyzed "implies that there is as yet no evidence for climate-change forcing of these storm characteristics over recent historical times.""
