I've got a shiny dollar that says they're in the northern hemisphere.
”The scientists don’t know exactly who, or where, that person would be. A U.S. observatory in Hawaii found CFC-11 mixed in with other gases that were characteristic of a source coming from somewhere in eastern Asia, but scientists could not narrow the area down any further”
Can someone summarize how CFCs achieve the result of depleting the ozone layer? When I was a kid someone pointed out that CFCs were quite heavy and it was not possible to make it up to the ozone layer. Also, my kid logic considered the science experiment where the teacher showed us a basketball with a light shining through a peg-board onto. At the polls the circles were elongated, thus demonstrating how less light (t…
Thunder storms very quickly lift particles sometimes as high as 60,000ft, and there's other phenomena such as mountain lee waves that are mixing air in excess of 120,000ft, well into the Ozone layer.
Also, if mountains do it, then why aren't there ozone holes above mountains?

Anyway, note that the atmosphere isn't perfectly partitioned by mass (or do you run on Nitrogen?) and that the poles naturally tend to have less ozone for other reasons.
It's bizarre that you give more credence to your reasoning from limited facts than to the conclusions published by people trying to do real science. Here's an "earth scientist" answering your question:

>Although the CFC molecules are indeed several times heavier than air, thousands of measurements have been made from balloons, aircraft and satellites demonstrating that the CFCs are actually present in the stratosphere. The atmosphere is not stagnant. Winds mix the atmosphere to altitudes far above the top of the stratosphere much faster than molecules can settle according to their weight. Gases such as CFCs that are insoluble in water and relatively unreactive in the lower atmosphere (below about 10 kilometers) are quickly mixed and therefore reach the stratosphere regardless of their weight.

That's the first Google result for searching "Chlorofluorocarbon heavier than air".
Ozone production is tied to solar activity disproportionately, and the 11 year cycle between the solar maximum and the solar minimum effect ozone measurements. We are currently at solar minimum, and we are also possibly headed into a grand solar minimum (an extended period of low solar activity). Zaelke also does not seem to have published a paper on his findings, and all of his quotes in this article are largely pol…
The article I read didn't discuss anything about the effect on the climate. AFAIK the primary concern isn't about direct effects on climate, but the loss of the ozone layer lets through vastly more UV light, which has a sterilizing effect on the oceans and is extremely harmful to human health. The fact that this did not have a big economic impact (the way action on climate change could) also means that it's been less controversial to actually do something about it.
Earlier quoted context omitted.

Do thunder storms do that consistently year after year to the same location with only one type of pollutant? Cause I've never heard of any other kind of pollution pooling at the poles, why only CFCs? Also, if mountains do it, then why aren't there ozone holes above mountains?
The reason I ask, is because the way you are asking questions makes you look like a layperson using intuition to guess something that scientists already understand fairly well.

I’m sure there much more reading material out there than just the two Wikipedia pages you linked. Try the following for some more: https://en.m.wikipedia.org/wiki/Ozone_depletion
