I wondered about that also, here is what I found:

| Quote: | The ozone hole is a different problem.
Many people confuse the hole in the ozone layer with climate change. However, these two problems are not closely related. The ozone layer protects the earth from harmful ultraviolet light that can cause skin cancer and damage plants and animals. The main cause of the hole in the ozone layer is chlorofluorocarbons (CFCs), gases that are used in refrigerators, air conditioners, and industrial applications. While CFCs alone cause warming, their ozone destruction can cause cooling. So far these warming and cooling influences have approximately balanced. Prior to 1978 CFCs were used as a propellant in aerosol spray cans, but that use has ended in the U.S. Under an international agreement most uses of CFCs are now being phased out to protect the ozone layer. |
