Well, hat's off to Perry!  Earth goes through cyclical periods of weather changes.  The 'scientists' that btw, are handsomely paid via government for their opinions and research, are doing nothing but keeping the cash rolling in.  Earth has been around for billions of years, has gone through many climate changes, from Ice Ages, to tropical climes, and these 'scientists' want you to believe that in 100 short years, vs. billions of years, MAN has caused weather to change.  Not to any great degree, not a whole degree of change, but the money keeps rolling in for these 'science', Nonsense!
