Qing-Bin Lu has been trying to promote this nonsense since 2001: Ozone Layer Burned by Cosmic Rays %P% Physical Review Focus.
That part may be legit. I do not know enough about atmospheric ozone chemistry to comment - certainly not without reading several dozen papers.
At first glance…
Cosmic rays are real, CFC’s do their thing because of free radicals - which is to say it is conceivable that charged particle interactions could affect their interactions.
Now, past that, however, I do know a lot about CO2 absorption and energy budgets in the atmosphere. I have a very hard time seeing how that could possibly be a bigger signal. I also sincerely doubt, very sincerely doubt, that he is actually saying that in his papers.
