The globull warming activists refer to those of us that don't believe it's caused by man as "flat earthers." But they remind me of the "scientific" theory of "spontaneous generation" from the middle ages. Wrap a cloth around a piece of cheese and put it in a cabinet, come back later and open the cabinet and, voila! A rat has spontaneously generated! They believed that if two unrelated objects were found together, then one must cause the other.
