Were the hurricanes that hit Florida last summer evidence of global warming?  Well, while one lead scientist at the U.N. recently made that connection, another resigned over the inference this could be the case. Chris Landsea of NOAA was an important scientist on the U.N. panel looking into hurricanes and climate change.  Recently, in an open letter to the public, he indicated that there has been no reliable trend indicating an upsurge in hurricane activity, and the modeling indicates global warming, if it exists, wouldn’t impact hurricane activity much at all.  Landsea’s resignation letter finished by stating he felt the process examining global warming was tainted by quote: “pre-conceived agendas” and was “scientifically unsound.”
