Protecting the Ozone Layer Greatly Slowed Global Warming

Global warming would be substantially worse right now if not for an international agreement in the 1980s that banned the use of ozone-destroying chemicals, a new study finds.

By curbing their [chlorofluorocarbons] use, the pact has also cut in half the amount of greenhouse warming that would have occurred by 2010 had these substances continued to build unabated in Earth’s atmosphere, according to the study published in the this week’s online issue of the Proceedings of the National Academy of Sciences.

The amount of warming that was avoided is equivalent to 7 to12 years of an increase in carbon dioxide concentrations in the atmosphere.

This is not a big surprise to me, as it seems almost logical that a
chemcial that was depelting the ozone, would also act as a green-
house gas.

Thankfully the chemical was outlawed internationally when it was.
