Just back from a visit to Perth, Western Australia for the United Nations Environment Programme Environmental Effects Assessment Panel (UNEP-EEAP). While we were there someone asked if the ozone hole was still there. The answer is very much so. It is predicted to recover by about 2060, but here is what it looked like last week and you can see all of Antarctica beneath it. So as we think about the Paris meeting and what we should do with greenhouse gases it is a useful reminder that we can act together and change things. In the 1980s we regulated CFC and other Ozone Depleting Substances. BUT once you mess with Earth's climate it takes a while to fix. So we need to get on with it.
