Bjorn Lomborg: ‘Facts don’t support climate-change-caused-typhoon-Haiyan. Strong typhoons declining 1950-10.
Lomborg: 'When people claim global warming caused typhoon Haiyan, they might want to realize that strong typhoons have *declined* since 1950 in the Western North Pacific (graph).
In Weinkle et al, 2012 "Historical Global Tropical Cyclone Landfalls" (http:// sciencepolicy.colorado.edu/ admin/publication_files/ 2012.04.pdf), you see how not only in Western North Pacific but generally, there is no trend in hurricanes across the world.'
In the paper’s conclusion:
“The analysis does not indicate significant long-period global or individual basin trends in the frequency or intensity of landfalling tropical cyclones of minor or major hurricane strength.”
When some people, like Jeffrey Sachs see a trend for hurricanes, it is because they look at the trend from 1981-2005 (conveniently from very low to very high).
