Last week the world, or at least a part of it, finally did something. At a conference in Montreal sponsored by the United Nations Environment Program, 24 countries signed a milestone accord that promised to halve production and use of ozone-destroying chemicals by 1999. "There has never been an agreement like this on a global scale," exulted Winfried Lang of Austria, chairman of the conference. Said Lee Thomas, administrator of the U.S. Environmental Protection Agency: "The signing shows an unprecedented degree of cooperation among nations of the world in balancing economic development and environmental protection...
...Montreal Protocol is aimed at reducing CFCs, which are used as coolants in refrigerators and air conditioners and are an important ingredient in aerosols and plastic foams. The pact would limit the use of an ozone- destroying group of fire-suppressant chemicals called halons, which some scientists believe cause as much as 20 times the damage of CFCs. Scientists estimate that overall as much as 7% of the ozone belt, which stretches six to 30 miles above the earth, has already been destroyed. Moreover, researchers have found evidence of "holes" in the shield, including one above Antarctica that approaches...
...Montreal negotiations, which capped nearly five years of talks, lasted nine days and involved some 150 scientists, environmentalists and industry representatives. The protocol allows developing countries to increase CFC use for ten years, in the interest of making more available to them items like refrigerators. It permits the Soviet Union, which plans its economy in five- year cycles, to go ahead with production scheduled through 1990. Thus the amount of the chemicals produced worldwide will actually grow by as much as 15% in the coming decade, cutting the real decrease by 1999 to just...
Representatives from 35 countries met in Montreal last week to hammer out an agreement that would limit man-made damage to the atmosphere's protective ozone layer. As they deliberated, the British journal Nature published a study offering the strongest evidence so far that man-made compounds called chlorofluorocarbons (CFCs) are the culprits. Crofton Farmer, principal author of the study and an atmospheric physicist at the Jet Propulsion Laboratory in Pasadena, Calif., reported that data gathered last year in the Antarctic are "entirely consistent" with the premise that CFCs -- used in refrigeration devices and as ingredients in plastic foams...
...clouds on the horizon, the Seoul Olympics still promise to be perhaps the best-organized and best-equipped event ever. Over the past decade, South Korea has spent some $3 billion on preparations for the Games. Moreover, it finished the work well ahead of schedule, whereas at Montreal in 1976 the readiness of the facilities was in doubt right down to the wire. The graceful, 100,000-seat Olympic Stadium on the bank of the Han River, site of opening and closing ceremonies as well as track-and-field events, was finished in 1984. Eight miles south of the city...
