Oh, so this is about the indirect effect of UV on plant growth reducing carbon uptake. Cool study. CFCs are also highly potent greenhouse gasses due to their long atmospheric residence time and the fact they have very different absorption spectra than everything else out there.

The Montreal Protocol is a lot like the chemical weapons ban: a ban of something the rich and powerful really don’t need that is incidentally the right thing to do. This kind of enforcement regime will work on fossil fuels in about 20 years when we have fusion power, but until then incentives are too greatly against it.
