A new MIT-led study confirms that the Antarctic ozone layer is healing as a direct result of global efforts to reduce ozone-depleting substances such as chlorofluorocarbons or CFCs. This is significant because scientists have observed signs of ozone recovery in the past. However, the new study is the first to show, with high statistical confidence, that this recovery is due primarily to the reduction of ozone-depleting substances, instead of other influences such as natural weather variability or increased greenhouse gas emissions to the stratosphere.
“There’s been a lot of qualitative evidence showing that the Antarctic ozone hole is getting better. This is really the first study that has quantified confidence in the recovery of the ozone hole,” says study author Susan Solomon, the Lee and Geraldine Martin Professor of Environmental Studies and Chemistry. “The conclusion is, with 95% confidence, it is recovering. Which is awesome. And it shows we can actually solve environmental problems.” Continue reading
