...deteriorating condition of the environment gives the "Green Lights" program special urgency. Each square foot of workspace lit by this more efficient system would save three kilograms of carbon dioxide emissions per year. Stemming future emissions of "green-house gases" has a great enough importance to justify whatever small job loss could occur on the national level...
...faster than predicted. That warning from scientists has led 93 nations to agree to speed up phasing out use of chemicals that destroy the atmospheric shield. Updating the timetable known as the Montreal Protocol, delegates at a United Nations conference in Copenhagen moved up elimination of chlorofluorocarbons (CFCs) and carbon tetrachloride to 1996, four years ahead of schedule. Halons and methyl chloroform will be banned earlier too, in 1994 and 1996, respectively. Researchers forecast more skin cancer as the ozone layer disappears...
...house calls, providing the advice and equipment that have helped six of his patients take their own lives in the past two years. The last to die was a 46-year-old Pennsylvania woman suffering from cancer. Catherine Andreyev used a mask to inhale a fatal dose of carbon monoxide last Monday in Waterford, Michigan...
...waves, plowed open by ice or formed by lava. But to speleologists, the most interesting are those that have been etched out of limestone by acidic water flowing underground. For a long time, researchers believed that nature could accomplish this feat in only one way: through the action of carbonic acid, which is produced when water reacts with carbon dioxide. The weak acid slowly dissolves bedrock. An underground stream forms, and an elaborate network of chambers like those found at Mammoth Cave in Kentucky takes shape. The unusual limestone terrains where this process occurs are known as karst, named...
