...last comparable meeting of the Western Hemisphere's leaders took place in 1967 in Punta del Este, Uruguay, attended by President Lyndon B. Johnson and 19 others...
...meetings were called as a midterm review of the Uruguay Round of trade negotiations, launched in the beach resort of Punta del Este two years ago. The purpose of the Montreal gathering, held under the auspices of the 1947 General Agreement on Tariffs and Trade: to establish guidelines for furthering free trade. Instead, last week's GATT meetings, involving delegates from 103 nations, were dominated by an inconclusive and bitter row between the U.S. and the European Community. The chief issue was an American demand that all nations agree to the total elimination of subsidies to farmers, which...
...Propulsion Laboratory in Pasadena, Calif., announced that his ground-based observations as a member of the 1986 Antarctic National Ozone Expedition pointed directly to a CFC-ozone link. "The evidence isn't final," he said, "but it's strong enough." Earlier this month, results from NASA's Punta Arenas project confirmed the bad news. Not only was the ozone hole more severely depleted than ever before -- fully 50% of the gas had disappeared during the polar thaw, compared with the previous high of 40%, in 1985 -- but the CFC connection was more evident. Notes Sherwood Rowland, a chemist...
...while most scientists agree that atmospheric chemistry and dynamics are major causes, the increased scrutiny of the Antarctic atmosphere following the discovery of the hole has seriously undercut the sunspot theory. Data from Punta Arenas, says Robert Watson, a NASA scientist involved in that study, made the verdict all but final. Nitrogen and ozone levels were down, but concentrations of chlorine monoxide were 100 times as great as equivalent levels at temperate latitudes. Says Watson: "We can forget the solar theories. We can no longer debate that chlorine monoxide exists and that its abundance is high enough to destroy ozone...
...plane around during landings. With special scientific instruments installed in pods on its long, droopy wings, the ER-2 is "like a big albatross -- it's heavy-winged," says Operations Manager James Cherbonneaux of NASA's Ames Research Center. While watching a particularly hairy approach to the runway at Punta Arenas, he recalls, "I chewed a little bit of my heart...
