The annual hole in the Ozone is a problem, but the earth warming? Tell me if I'm wrong.

The earth does naturally warm up and cool down over time, however it does so over a vastly greater amount of time than what we have seen in the past 100 years. According to geological evidence, since the last Ice Age, the earth has warmed about .25 degrees a century. Compare this to a 1 degree change in this past century and an estimated 1.6-6.3 degree change in the next century.
The destruction of the ozone layer should be a major concern, but for different reasons. Ozone acts to block UV rays from reaching the surface. UV rays do not have any effect on 'global weather' but are harmful to humans. It can damage the retinas of the eye and cause skin cancer. This is why Australia (the closest country to the 'hole in the ozone' has the highest rate of skin cancer per capita
