My comments are directly related to warming supposedly cause by CO2 emissions. This whole ozone thing is a completely separate issue.

Yes Eon is right. The Ozone layer absorbs a specific range of sunlight known as Ultraviolet-B, or UV-B. It also serves to modertate daytime and nighttime temperature swings, but only slightly. Without it, we would have much more skin cancer, cataracts, and other forms of cancer and DNA damage. Crops exposed to that much more UV-B would become damaged and inedible. Phytoplankton would also become damaged.
Thanks to reduction in CFC's, the Ozone hole is now on the mend.

If we can get our shit together on the Ozone Hole, maybe we can do the same for Global Warming.
