It is getting better, but it won't really recover until 2050 to 2060's AFAIK. That said, there are other gasses which might still be bad to let into the atmosphere, so we still don't understand it a 100% There's also the ozone hole, which partly affects Australia [0], but mostly Antarctica. I think it is really interesting, that about 2/3 of people in Australia will get skin cancer at some point, and I've wondered whether it's due to the increased exposure to, what is essentially radiation, or just the mass migration of people who were originally not native to the region. Thus they don't handle the sun as well, as say, Aboriginals.
