Complete and utter bollocks...............Not in the Stratosphere you idiot.There is a natural circulation current called the BDC (Brewer Dobson circulation) that transports air and O3 from the Tropics to the Poles, and hence will CFC's as well.I suggest you learn something before you utter on here my friend.Actually its the first post I have seen from you that is not about Dyson and/or Polar bears.N
