Although global warming could cause the number of tropical cyclones to decrease around the world by the end of the century, the storms that do form probably will be more intense . . . Landsea says the potential increase in strong hurricanes is "pretty tiny. We're not looking at any drastic increase by 2100." For example, he says, a 150-mph hurricane might increase only to a 157-mph hurricane. "In my perspective, that's a little change, a long ways in the future."http://www.usatoday.com/weather/storms/hurricanes/2010-02-22-Hurricanes19_ST_N.htm
In other words, man-made global warming will result in fewer "tropical storms, hurricanes, typhoons and cyclones", and those we get will only be a "tiny" bit stronger.
It becomes clearer each day that the Hollywood movie version of global warming is an exaggeration.
