...doing so at least twice: during the New Hampshire primary campaign, when he dropped 13 points in four days, to the edge of extinction; and in June, when he had the Democratic nomination locked up but was running behind Perot as well as Bush. In early February columnists Rowland Evans and Robert Novak reported that "mainline Democratic politicians" considered Clinton to be "one of the walking dead who sooner or later will keel over." That sentiment would be repeated many times until the late-summer polls gave...
Stung by heavy losses and highly critical of management, many of the Names (as investors are known) who make up the Lloyd's insurance market had long demanded the resignation of chairman David Coleridge, 60. Last week Coleridge stepped down and nominated as his successor David Rowland, 58, chief executive of the Sedgwick Group, an insurance firm. Since Rowland is considered a close associate of the former CEO, dissident Names are less than euphoric...
What also frightens scientists is the fact that CFCs remain in the atmosphere for decades after they are emitted. In their original research, Rowland and Molina estimated that CFCs can last 100 years or more. Even if CFC production stopped today, researchers believe that stratospheric levels of chlorine would continue to rise, peaking during the first decade of the next century and not returning to anything like natural levels for at least a century...
...ozone story is a tragic saga of doubt and delay. Rowland recalls that for several months after his original ozone paper was published in 1974, "the reaction was zilch." It was not until 1978 that the U.S., but not most other countries, banned the use of CFCs in hair sprays and other aerosols. Not until the Antarctic ozone hole was confirmed in 1985 did nations get serious about curbing all uses of CFCs. By now as many as 20 million tons of these potent chemicals have been pumped into the atmosphere...
...common suggestions is, 'Why don't we just ship L.A.'s ozone up?' " says chemist Sherwood Rowland. "Well, 30% of the ozone is in the stratosphere, and it drifts down from there to the lower atmosphere rather than the other way around. The energy that would be needed to move the ozone up is about 2 1/2 times all of our current global power use. If you could take every power plant in the world, every piece of coal and every oil tanker, the energy would be insufficient -- and then you'd still have the problem...
