Thanks to 1987 Accord, Signs of ‘healing’ ozone layer over Antarctic: study

Signs of ‘healing’ ozone layer over Antarctic: study | Daily News: The hole in the ozone layer over the Antarctic has begun to shrink, signaling good news for the environment decades after an international accord to phase out certain pollutants, researchers said Thursday.

The study found that the ozone hole had shrunk by 1.5 million square miles (four million square kilometres) -- an area about the size of India -- since 2000.

“It's a big surprise,” said lead author Susan Solomon, an atmospheric chemist at the Massachusetts Institute of Technology, in an interview with Science magazine.

“I didn't think it would be this early.” The study attributed the ozone's recovery to the “continuing decline of atmospheric chlorine originating from chlorofluorocarbons (CFCs),” or chemicals that were once emitted by dry cleaning, refrigerators, hairspray and other aerosols.
