This clown must have a pocketful of two-headed coins: after years of telling us that our warm winters are absolute proof of global warming, he now discovers that cold winters are the real proof! One of the key attributes of any meaningful scientific theory is that it be falsifiable, that is, there must be some conceivable evidence one could uncover that would show it to be wrong.
Global warming seems to fail this test, since what would appear to be contradictory evidence is cited in support.
You beat me to it. Yes, a theory that admits all contradictory facts is unfalsifiable, therefore unprovable, therefore not a theory or hypothesis at all.
