re: ...Don't pick at that, it'll never heal...
HCFCs, IIRC, are about as bad as CFCs while in the atmosphere, but are destroyed by atmospheric processes much more quickly. Again, IIRC, I think they persist about 10 years versus 30-50 years for CFCs.
That global graph didn't specify what atmospheric layer was being analyzed. My understanding is that the lower atmosphere, the source of chlorines, has dropped concentration, but it takes 10 years for that decrease to work its way up to the stratosphere. My recollection is that after 2010 is when a slow improvement is expected.
