Read here. Leftist/liberal politicians, reporters, celebrities and pundits continually repeat global warming disaster claims of global warming alarmists without checking the actual facts. In the case of hurricanes, they claim that global warming is causing ever more destructive hurricanes. If this were so, the U.S. mainland would have suffered from an increasing level of hurricane strikes over the last few warming decades. As peer-reviewed researchers discovered, this is a blatantly false claim (or in the less gentile society of blogland, we call this claim a lie).
"The authors calculated return periods of Atlantic-basin U.S. landfalling hurricanes based on "historical data from the 1900 to 2006 period via extreme value methods and Poisson regression techniques" for each of the categories (1-5) of the Saffir-Simpson Hurricane Scale....They also state that the hypothesis that U.S. hurricane strike frequencies are "increasing in time" -- which is often stated as fact by climate alarmists -- is "statistically rejected."
