You propose that CFC's are harmful to the atmosphere, and I would tend to agree with that. The thing that I do not agree with is the now accepted belief that co2 (human caused carbon emissions) have been proven to cause climate change, which I think that you also stated you don't agree with.This debate seems talking about 2 different things. Anyway, here's my take. I became skeptical about Al Gore's brand of global warming when he refused to debate anyone on the subject because he said the debate is over, and he still has not to this date. Debates should never be over, especially before they begin. That proves how closed minded HE is.(Plus he will have a major stake in carbon offset transfers) As for CFC's, I'm no expert on the subject, but I believe the U.S. banned the use of them as propellants quite some time ago, which was the main cause of their introduction into the atmosphere, and that seems cool.
