Ozone Depletion

Paper Summary:

This paper examines the causes and effects of the depletion of the ozone layer which allows excess ultraviolet light from the sun to leak through and reach the earth's surface. The impact of excess UV light can be increasingly dangerous, harming crops, wildlife and farm animals and increasing the incidence of skin cancer in humans. The paper looks at the life cycle of an ozone molecule, ozone holes and the TOMS (total ozone mapping spectrometer) Earth Probe which can measure the dimensions of an ozone hole. It evaluates the connection between ozone and cancer and provides a timeline for the history of the ozone hole.

From the Paper:

"Without the sterner controls on CFC production, ozone-damaging chlorine and bromine levels would have continued to rise steeply until 2100 and beyond. That was the conclusion of the World Meteorological Organization' s 1994 Scientific Assessment of Ozone Depletion, the most comprehensive and authoritative statement to date on the ozone question, prepared with input from NASA, the National Oceanic and Atmospheric Administration (NOAA), and the United Nations Environment Program. It is the product of 295 scientists from both developed and developing countries. Therefore, it represents an overwhelming consensus of the world's scientists about the severity of the threat to the ozone layer."
