Quote:Not all of it. You could do an experiment and easily test this. Some will settle, some will drift up. Ask yourself this...why does smoke rise?

Because the warm smoke is less dense than the surrounding air, same as a hot air balloon. CFCs are more dense than the surrounding air. If you were heating the CFCs, maybe they would be less dense and behave like smoke, but unless we are talking about pyromaniacs using aqua-net as a blowtorch, this isn't typically what we do. 

 

Since the smoke is less dense than the air it rises and the CFCs are more dense so they fall and settle... this seems to prove my concerns about the CFCs in the atmosphere more than disprove it. Even if some escaped someones home and got picked up by wind currents, I can't see how that is enough to effect things on a large scale. \

 

 

Edit: Upon further examination, smoke isn't less dense, but even smoke eventually settles.
