If he couldn’t explain it to us unwashed masses, then perhaps he should have foregone the lil movie altogether, hmmm?
However, the facts do not really matter here. What matters here is the interpretation of observed facts, the creation of emotionally appealing stories based on the observations, and endless repition of them until they become part of folklore.
Honestly fellas, you would be better off trying to stamp out nursery rhymes. You might as well try and talk to Muslims about Baby Jesus. What the Global Warmers have done (and rather brilliantly) is confuse two concepts in the public mind (Not all that hard, now is it?):
Pollution can be very nasty. It really doesn't cause global warming ... or cooling. One healthy volcanic burp puts more crap in the atmosphere than 3 centuries of industrial development, and can actually kill people, rather than offer them useful work.
Big deal. This argument is over. You can point out that CO2 has got nothing to do with it until you are blue in the face.
That will merely be attributed by Al and the Warmers as yet another symptom of Global Warming.
