Ozone depletion has stopped:
“The protective ozone layer in the earth's upper atmosphere has stopped thinning and should largely be restored by mid century thanks to a ban on harmful chemicals, UN scientists said on Thursday.”
“The "Scientific Assessment of Ozone Depletion 2010" report said a 1987 international treaty that phased out chlorofluorocarbons (CFC) -- substances used in refrigerators, aerosol sprays and some packing foams --- had been successful.”
In 1987 we came together, regulated the use of CFCs, solving this problem -- and it worked. Now we can do the same thing with CO2 and twenty years from now look back on the climate crisis as a thing of the past.
