So...what is it?

[rational gaze]

I quick question, some people say it is the holes in the ozone that is causing global warming. While others say it is the added ozone because of Co2. I don't understand how it could be both, so which is it? Too much ozone or not enough??

I don't know shit about shit but I know that co2 =! ozone

Global warming has bugger-all to do with the ozone layer. The ozone layer filters UV rays out of sunlight, less ozone = more UV light reaching the Earth's surface. And whilst ozone acts as a greenhouse gas near the surface, the ozone layer is too high up in the atmosphere to have any significant affect on global mean surface temperature (GMST). Global warming is primarily dependent on the relatively near-surface atmospheric concentration of greenhouse gases such as CO2, N2O, SO2, CH4, CFC's*, amongst others.

*CFC's also catalyze ozone back into oxygen, but this catalysis doesn't affect the GMST.

I could be wrong, but it's also dependant on the Sun's cycle, isn't it?

I've read a lot about the sun being unusually active, creating a warming trend on Earth.
