In my wildest dreams I had hoped that trumpy would revive atmospheric physics. It's been dead since the 80's when it went against the mainstream of ozone holes and carbon dioxide.
So, we get these articles, all very nice stories designed to get money from the public. The physics tells us that the bromine, chlorine reaction does not exist. Also they never include fluorine in their stories because the new coolants are all fluorine based.
The only thing that increases an ozone hole is a vicious polar vortex, bringing temperatures and pressures down in the middle. We'll get lots of these in the next decade, so be prepared for a big hoo-ha. :)
