This article doesn't address the CFC effect relative to the effect of CO2 emissions fallout landing on the glaciers and polar ice caps, which changes the albedo of the ice, resulting in melting them. More and more ice melts every year, and less re-freezes, raising the sea level, altering the salinity, changing the worldwide currents, resulting in massive change to the ocean biomes. Does that result in less climate change than CFCs eroding the ozone layer over the poles?
