Hello Brad,

You are confusing ozone depleting gases with greenhouse gases.

Carbon dioxide, methane, etc. are greenhouse gases
which trap the Earth's reflected heat from the Sun.

Refrigerants like hydrofluorocarbons (HFCs) are ozone depleting gases
which destroy the ozone layer protecting us from the Sun's radiation.
