Hi LindyBill; I was going to post on the subject of freon and how it gets high in the atmosphere, but I see it has already been adequately covered. By the way, even if the atmosphere never mixed at all, there would still be appreciable CFCs at high altitude. You can calculate how much by using something called Boltzmann's constant, if I recall correctly. If it were otherwise, the fact that Oxygen is heavier than Nitrogen would prevent jet aircraft from operating at very high altitudes. But I agree that the ozone fears are exaggerated. My argument is that the ozone only disappears in places where there is very little sunlight, and therefore little need for ozone to protect from sunlight. -- Carl@slowlycatchinguponthethread.com
