That’s what I was saying, sorry if I wasn’t clear. We know CFC’s will destroy O3, hell lots of things will break down O3 worst thing O3 can run into is a single O molecule...:)
The main point I was trying to make is, for all we know, there has been a hole over the south pole for eons...We found the hole the first time we looked.. so we have no historical reference to know how long its been there.
I’m not against the banning of CFC’s, evidence is pretty clear they do indeed have impact on Ozone, just not sure of the doom and gloom scenarios that were tossed about back when they were trying to get the ban passed.
To my knowledge there is no documented proof that CFCs will have adverse effects on any atmospheric models. Correct me if I am wrong...it’s all about making jobs for indigent college types (The EPA).
I spent some time in Australia - the cancer risk down there is real. Settled science. They are religious about the steps people need to take before going outside.
This was especially true in Taz, Barossa Valley, Melbourne, Perth, etc.
