"A Mysterious Rise in Banned Chemicals Is Warming the Planet

A new study documents the mysterious presence of five banned chlorofluorocarbons, chemicals that not only deplete the ozone layer but also contribute to global warming

Five ozone-depleting substances are increasing in the atmosphere, a new study finds, despite an international ban on their use and production.

The discovery has mystified scientists and alarmed them because the substances are warming the planet. Their climate impact is equivalent to the carbon emissions from a small country.

“We don’t really know where it’s coming from, and that’s really a bit scary,” said study co-author Stefan Reimann, a scientist with the Swiss Federal Laboratories for Materials Science and Technology, at a news conference on Monday."
