Though I know it wasn't your intent, I just want to call out explicitly that ozone layer depletion and global warming are two separate mechanisms. Yes, CFCs (Chlorofluorocarbons, the molecules that destroy the ozone layer) are also strong greenhouse gases, but they are present in such small amounts that their effect on global warming is negligible. In the case of the ozone layer, we took action in time and the ozone layer is repairing well [1]. (Somewhat coincidentally - also from the same source - I just learned that warmer global temperatures actually inhibit ozone layer depletion.)
