So I guess getting rid of all that R12 was just a big waste of time?

Actually not; the article notes that improvements are being measured. It just takes time for the Earth system to react to them.

I'm not anti-environment, but I have never seen any documentation/proof that there was NOT an ozone hole at the South Pole to begin with. If elimation of R-12 is the answer, I'm all for it, but it would be nice if I could see the "before" info, that demonstrates beyond a doubt, (sorry, but I distrust anything from the anti-Capitalist crowd, aka the "Greens").
