Scripps Researcher Finds Ozone-Eating Chemical Level Falling

A San Diego scientist says a surge in outlawed ozone-depleting gasses appears to be easing. Scripps Institution of Oceanography researcher Ray Weiss says levels of chlorofluorocarbons (CFCs) in the atmosphere began rising a few years ago, even though they had been outlawed by the Montreal Protocol. The chemical was once used as a refrigerant and in the manufacture of foam, but CFCs were outlawed more than a decade ago.
