I hear that a lot Thrawn... years later the whole thing changes again... temps go down, go up in other areas, droughts get real bad, then get better, flooding gets real bad, then gets better..
As for using your drought argument in the mid-west of the US...
There have been several severe droughts there in the course of US history...
Next thing you'll know, earthquakes are a result of too many overly flatulant overweight men and women and volcanos are the inner center of the earth suffering explosive diarhea.
I know all about the greenhouse gases, last time I heard anything about them... they were reduced drastically, both in the atmosphere and in output... well, for certain countries.. there's still a flotilla of third world countries without any pollution regulations....
