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...
