scolored rigid vinyl home sliding, and it also may cause vinyl pipelines to become brittle, leading to more serious problems if say, natural gas pipes should leak or burst. Indirectly, added UV radiation is expected to stimulate climatic condition that promotes smog ozone pollution. Studies show that ozone concentration would peak earlier in the day and at greater distances from the source, with the result that a larger human population would be exposed at risk. Gases that help destroy atmospheric ozone also play a part in another environmental problem, the gradual warming of the earth due to an enhanced greenhouse effect. Is a process by which the sun’s infrared rays hit the earth’s surface and then radiate heat back in the troposphere. Some heat escapes into space but the rest is trapped by naturally occurring carbon dioxide and other gases that act somewhat like the glass of a greenhouse surrounding the earth, keeping it warm. Without the warming, the planet would be too could to sustain life. But human activities have loaded the atmosphere with carbon dioxide, CFCs, and such gases as methane and nitrous oxide. Creating an imbalance in the climate system - an enhanced or forced greenhouse effect, which scientists predict could, by the middle of the next century, make the earth warmer than it has been in the last two million years.Another greenhouse effect gas is methane, which comes from the cattle waste, termite nests, and rice paddies. In 1987, atmospheric chemists at the University of California released a report showing that methane had steadily increased in the troposphere and measured 1,7ppm, 11 percent higher than a decade before and 2,4 times higher than it has been over the past 160.000 years (Grave threat to....).Atmospheric scientist are looking at the possibility that increased cattle raising, increases the amount of acreage worldwide devoted to rice planting, and an explosion of termite populations which thri...
