Interesting secondary point to the article... but, the big but, is that ozone depletion is not related directly to global warming. I said it before, I might as well explain in more detail why I say that:

Ozone is created naturally (by the UV radiation actually), it's a continuous process in an equilibrium related to the UV insolation. Ozone then reduces UV rays because once it forms it absorbs them (O3 splits into an oxygen molecule, O2, and an Oxygen radical, the radical can react with another O2 molecule to reform ozone, IIRC there's a lot more steps and reactions involved, but that's beyond the point here).
CFC (chlorofluorocarbons) altered this equilibrium. These are organic carbon molecules where the hydregens have been replaced with chlorine and/or fluorine atoms. In the atmosphere they are unstable, UV radiation (and/or other reactions) splits them appart and creates free radical atoms of Chlorine and Fluorine which then react with oxygen radicals and/or with ozone, reducing the concentration of O3.
Also, remember that this is the stratospheric (or whatever-the-actual-layer-spheric) ozone. The ozone in our polluted cities is not the one that protects us from UV rays, quite the opposite, it can be harmful because is very reactive.

The worst greenhouse gases are Carbon Dioxide (CO2, the same gas that carbonates your beverages, byproduct of all combustion processes including those controlled combustions we call metabolism) and Methane (CH4, produced by decomposition of organic matter, and as a byproduct of some bacterial metabolic processes, as well as found in fuel deposits of natural gas, there are also some large reservoirs of CH4 in the seafloor in the form of methane hydrate gas).
These create warming because they absorb infrarred radiation (heat) and reflect it back to earth. There's a reason why it's called greenhouse effect: like in a greenhouse the glass allows light to come in, when that energy is re-released as heat instead of iradiating out in space is trapped by those gases.
Have you ever seen in the weather forecast comments about the night becoming quite cold because there is no clouds? That is an example of how much heat the Earth sheds as infrarred radiation out to space at night. Greenhouse gases trap some of that.

They're related because both are problems caused by humans polluting the atmosphere, but global warming does not affect ozone concentrations, and larger UV insolation does not have a direct effect on warming or on the greenhouse effect.

As far as I know and see they're not directly related (but remember the warning above, I did learn some of these things in my chemistry classes but not to an expert level and is not part of my everyday work). If you know that there really is a relationship between ozone depletion and global warming please point me to a reference (preferably as close to a scientific site as possible, and not an axe-grinding site), I'd like to learn more about it.

Not that I'm saying that is wrong to discuss both things in the same thread (nor saying that DW implied they're related), but trying to clear a misconception that Brian already expressed, because misunderstood information can be as dangerous as ignorance.
