U.S. and Dutch scientists credit the 193-nation agreement to ban ozone-depleting substances for avoiding nearly catastrophic environmental hazards. The National Aeronautics and Space Administration, Johns Hopkins University and the Netherlands Environmental Assessment Agency scientists said if the ozone-banning treaty known as the Montreal Protocol that went into effect in 1989 hadn't existed, nearly two-thirds of Earth's ozone would have disappeared by 2065. That would have caused...

SAN FRANCISCO -- The recovery of the Antarctic ozone hole may be delayed until 2065 because reservoirs of ozone-destroying chemicals may be larger than anticipated, according to research presented on Tuesday. Ozone in the upper atmosphere blocks harmful ultra-violet rays and scientists expect the ozone layer will heal itself in the absence of large chemical emissions. Researchers speaking at an American Geophysical Union meeting said reservoirs of the chemicals in developed countries may be...
