From the first time I heard the term "Global Warming", I thought,"Well, gee. Would those happen to be the periods between, "Ice Ages"? These extremes have been swinging back and forth on this planet Long before nature even Thought of something like Us. Adapt or die, It's not ugly. It's the reason Everything looks and acts the way it does. It's just "What Works"..We are the culmination (so far) of a process Billions of years running. We're so smart we just Know WE'RE the cause of "Global Warming" ? Wow ! That is Vanity..
