Read here. Fanatical global warming alarmists, such as Al Gore, have aggressively publicized extreme green/left/liberal catastrophic scenarios over the past decade. These predicted catastrophic scenarios are then widely disseminated, and popularized, by the mainstream media and Hollywood in an attempt to bias both policymakers and the public.
Unfortunately for the likes of Al Gore and the MSM, the predicted catastrophic scenarios, such as an increased frequency of severe hurricanes and cyclones, keep proving to be nothing more than wild, exaggerated speculation.
A comprehensive review of the world's best, recently published peer reviewed research, by scientist Jonathon Nott, determined the Al Gore/IPCC's Climategate science speculation that global warming would cause an increase of catastrophic hurricanes and cyclones is not supported by any empirical evidence. Ergo, the green alarmist prediction of increased CO2 emissions causing more hurricanes from global warming is baseless.
"...the Australian researcher reports that "recent analyses of corrected historical TC records suggest that there are no definitive trends towards an increase in the frequency of high-intensity TCs for the Atlantic Ocean region (Knutson et al., 2010), the northwest Pacific (Chan, 2006; Kossin et al., 2007) and the Australian region, South Pacific and south Indian oceans (Kuleshov et al., 2010)." He notes, however, that "over multi-century to millennial timescales, substantial change has occurred in virtually all TC-generating regions of the globe," with "alternating periods of lesser and greater activity," writing that "the longer, coarser-resolution records display periods from multi-century to over a millennium in length, whereas the higher-resolution records register multi-decadal to centennial-length periodicities." In some of these cases, Nott says that (1) "different climate states, such as periods dominated by El Niños and La Niñas, appear to be responsible for the TC variability." In other cases, he says the responsible factor seems to be (2) shifts in the position of the jet stream, (3) solar variability, or (4) some unknown cause."
