I recall the hole in the ozone layer was going to kill the planet in the 1970s. Hairspray and spray-on deoderant were the major culprits. Remember those 70s hair styles? The Afros?
It is a wonder we survived. I think the reason was haircuts as we entered the 1980s.
Haven’t heard about holes in the ozone since 1993.
Until then, the are just watermelon Marxists promoting the latest control scheme.
FWIW, I think flooding the Qatarra would be a sensible stand alone project with or without global warming. It would be a giant step forward in turning back desertification on that part of the planet
