13 nations have signed on to the "plot" so I don't think it's political. Labs that have run scale models of the conditions both with, and without the CFC's introduced by humans found this: Before the introduction of these propellants in the `70's, the models matched what happened. Afterword, the two models split. Those with the CFC'S (as really happened) showed a sharp increase in the greenhouse gasses, (as really happened) the model where it was not (what if) did not. Maybe we DO have the power to affect our environment!

I also think it's funny when people say we're not destroying the planet because we're "natural animals doing what humans do!" (Hmmm, nuclear war, toxic waste, ozone, war, good stewardship, environmentalists, lawers, Peace Corps... Maybe we can "naturally" make some better decisions, regardless!) :-]
