UPI.com Science News published this report by the European Space Agency:

“Satellite imagery confirmed the ozone hole over Antarctica in 2012 was the smallest seen in the past decade, scientists with the European Space Agency reported.”

“The ozone sensor on Europe’s MetOp weather satellite surveyed the hole over Antarctica in 2012, adding to the long-term monitoring of atmospheric ozone started by its predecessors on the ERS-2 and Envisat satellites, a release form ESA’s Paris headquarters said Friday.”

“The ozone hole caused by human-made chlorofluorocarbons — CFCs — has been shrinking since international agreements banned the substances in the 1980s in an effort to protect this vital layer of the atmosphere that protects life on Earth from cancer-causing ultraviolet radiation.”
