Sallies, if we consider the last two thousand years of weather history that has gone on, in the Gulf of Mexico, the hurricanes we are now experiencing are likely, nothing out of the ordinary, and have little to do with man's carbon footprint?  Some of the same scientist that believe in Global warming also believe, the continents, at one time, were a single land mass; now, can you image the terrific amount of weather that did happen: seas rising, earth quakes, storms of all sorts, while continents were shifting?  The planet Earth has a weather history, and it is alive!

    Arvin it is unfortunate that science, becomes a matter of political attribution, with political voices, motivated one way or another, preying on the ambiguities of life, to win, their proposition, rather than stating science as science: we are afraid to say, "we really just don't know, and the information we have gathered could mean just about anything but definitely nothing absolute."
