Halting the use of Freon has reversed the loss of ozone. Science was correct, cut off the harmful pollutant and things will improve. Now HFC's are the second or third most prevalent greenhouse gas, and one we now have replacements available for. This is an easy fix, and HFC's don't linger for decades as CO2 does, it's the low hanging fruit that will reward us in most of our lifetimes.
I don't know if Congress has to OK these 3 events, if so, they will all be trashed.
