I guess I'm failing to understand what point you are making about any of this. They use the word hole because what else do you call it? A thin or non-existant area in the otherwise contiguous layer? Elsewhere they say hole without quotes. Who cares? If you don't call it a hole does that mean more cosmic rays aren't let in temporarily by the ozone "thin area"?What you linked is an opinion article, and not scientific research. Even authors use quotations with the word "hole" since there is no such thing as a literal ozone hole. There can be no permanent "depletion" of it either because it's an ongoing chemical reaction and not a "resource" that can run out.
If this is "absolutely something to worry about" then don't let me stop you . I feel like I am intruding.
Ozone is a molecule, not a chemical reaction. You claim that the layer of ozone in the atmosphere cannot possibly be reduced on any long term basis, but then why did anyone ever bother with the Montreal treaty?
Sure, I guess you could say that theoretically even, say, 100,000 rocket launches per day wouldn't "permanently" deplete it, since it might theoretically re form if the launches ever stopped. Actually we have no idea what would happen after radically reshaping the layers of atmosphere other than computer models and theories.
And, while (like all papers) it could be erroneous, a paper that synthesizes the findings of other papers is scientific research, and such papers are frequently cited as evidence by other papers in the scientific literature.
