Read here. The climate "science" being generated by climate models is so unsettled that one could suffer severe whiplash from the extreme flip-flops being experienced using the virtual (make-believe) techniques, which have proven incapable of producing accurate predictions.
Previously, the IPCC, and its merry band of climate modelers, claimed that global warming will cause hurricanes to be more intense. Now, the revised (better?) climate models say the opposite per a new peer-reviewed study by Perrie et al.
This pattern of recent flip-flops from climate models indicates how totally worthless they really are in assessing climate change impact. Policymakers should be very cautious in drawing any conclusions from such flaky model output.
"A paper published today in the Journal of Geophysical Research - Atmospheres finds that global warming should cause hurricanes to be less intense, contrary to claims of the IPCC and Al Gore. The paper also finds that global warming would also tend to shift hurricanes toward the north and thus decrease strength upon landfall or thereby decrease the likelihood of landfall."
"An understanding of the possible influences of climate change on the storm climate is achieved through our simulations. The impact of climate change is seen in slightly decreased intensities in landfalling cyclones (about 5 hPa) resulting from the competition between warming provided by the climate change scenario and modest cooling around the storm center induced mainly by dynamic cooling. An additional impact is that cyclone tracks tend to shift poleward." [William Perrie, Yonghong Yao, Weiqing Zhang (2010)]
