Global Warming & Hurricanes

For years now we have been hearing that global warming was causing the active hurricane seasons we have been experiencing. Not true according to meteorologist Tom Knutson in a recent study he released. In fact warmer water reduces the number of hurricanes we could experience. You can read it here at the Washington Post. I like what a meteorologist says at the end of the article, "But NOAA hurricane meteorologist Chris Landsea, who wasn't part of this study, praised Knutson's work as 'very consistent with what's being said all along.' " If that is what has been said all along, why are we just hearing about it now?
