Potentially more damaging than ozone depletion, and far harder to control, is the greenhouse effect, caused in large part by carbon dioxide (CO2). The effect of CO2 in the atmosphere is comparable to the glass of a greenhouse: it lets the warming rays of the sun in but keeps excess heat from reradiating back into space. Indeed, man-made contributions to the greenhouse effect, mainly CO2 that is generated by the burning of fossil fuels, may be hastening a global warming trend that could raise average temperatures between 2 degrees F and 8 degrees F by the year...
...long as five years after it leaves the ground, N2O may finally reach altitudes of 15 miles and above, where it is broken apart by the same ultraviolet radiation that creates ozone. The resulting fragments -- called radicals -- attack and destroy more ozone molecules. Another ozone killer is methane, a carbon-hydrogen compound produced by microbes in swamps, rice paddies and the intestines of sheep, cattle and termites...
...that this one may be different. They believe it is magnified by a fundamental change in world climate caused by a phenomenon called the greenhouse effect. Since the Industrial Revolution, people have been burning greater quantities of fossil fuels, such as coal, oil and gas. One by-product is carbon dioxide, which has entered the atmosphere in ever increasing amounts...
...While carbon dioxide allows the warming rays of the sun to reach the earth, it blocks the excess heat that would normally reradiate out into space. As a result, the atmosphere is gradually growing warmer, thus melting the polar ice caps and raising sea levels. It may be years before scientists determine just how significant the greenhouse effect is -- but they know the process is accelerating. Sea levels are expected to rise at least a foot in just another half-century...
...literary journal after going unpublished for two decades. Last month a group of ex-political prisoners and dissident writers applied for permission to publish their own magazine, aptly titled Glasnost. The government has so far given no official answer, but the first issue, in the form of typed carbon copies, has been allowed to circulate freely...
