What exactly is the deal with Ozone and its contradicting effect on Global Warming and Ozone depletion?

Question

I understand there is a faction of the population who feel global warming is not a result of increased greenhouse gas emissions. If you are a part of this faction please refrain from answering my question.

The number of Greenhouse Gasses has skyrocketed in the troposphere, carbon for one, ozone is another, and this over abundance of GG has been labeled the cause of the increase in earths surface temperature from just 13.5 Celsius rise over 150K years to a .6 Celsius rise in just the last 100 years.

We have a depletion of ozone in the stratosphere as a result of CFC’s; this is the cause of Ozone depletion.

Can someone explain to me how we can have this overabundance of Ozone in the troposphere and a shortage of Ozone in the stratosphere, both causing damage to Earth?

Answer 1

The Ozone in the troposphere harms living things, as it reacts with organic compounds. Since there are no living things in the stratosphere Ozone is good and blocks high energy radiation. Ozone from the troposphere is unable to get up to the stratosphere before it is broken down, so the two concentrations are unrelated. With respect to global warming, Ozone is a VERY SMALL part of the problem, the biggest problem is carbon dioxide. The levels of carbon dioxide would cause global warming even if Ozone didn't exist (but it wouldn't matter because we'd be dead).
In case you are interested CFC's are also greenhouse gasses, so they deplete the Ozone and increase the temperature.

Answer 2

Ozone absorbs UV lights, so w/o ozone, human will be dead.
For the CFC part, the Cl of CFC will break down the ozone, causing ozone to break down into O2 and O.
Greenhouse effect is a problem b/c of CO2, causing the temp to raise, but it does not absorb UV light

Answer 3

There is no contradiction. Throughout Earth's geological history periods of glaciation are followed by periods of global warming by precise meaurable mechanisms. What confuses people is understanding that cooling is always followed by warming and viceversa. But the intimate mechanisms responsible for it are too complex.
