Climate change is caused by the ionization of oxygen by UV.
The 99.9% of the gases in the atmosphere does not absorb heat, only 0.04%, known as greenhouse gases. The oxygen to be ionized by the UV, causes heat, because,
When the air is ionized,it becomes a good conductor of electricity and hence heat
This process occurs in the stratosphere and the temperature increases from-60°C to-5°C( increases 55°C),
in the troposphere where there is a greater amount of oxygen, the ionization is much greater.
