n first appeared. Ozone absorbs as well as reflexes ultraviolet and visible radiation; it retains heat from the sun. For that reason, when ozone is destroyed, that part of the atmosphere were the ozone loss occurs loses heat. This will allow more heat to enter the earth’s atmosphere. Scientist are now trying to determine if the cooling that occurs at altitudes where ozone is lost, spreads to lower altitudes and reduces temperatures on earth. There has been no ozone loss in the lower stratosphere over the tropics, which would cancel out a rise in temperature caused by CFC’s.International reaction to the proof CFC’s were destroying the ozone layer was swift. On September 16, 1987, 24 nations signed the Montreal Protocol on substances that deplete the ozone layer. The agreement was a program to protect the environment. The ratifying nations accounted for 99% of the world’s production of CFC’s, and 90% of their consumption. The Montreal Protocol called for freezing halon emissions by 1992 and for having CFC emissions froze by 1998. Also having CFC production and importation froze by 1999 (The Thin Blue Line 9). The United States government reflected its concern over the fate of the ozone. Convinced of the dangers the United States promoted an ozone action plan to other countries, many which were hostile to the idea. The drafters of the Montreal Protocol also assured its success by making it flexible. It could rapidly amend to reflex subsequent changes in environmental conditions or new Watson 5 findings. New findings were soon to test the flexibility. The hole over the Antarctica appeared bigger and soon instead of phasing out CFC’s by 2015, new guidelines set up phasing out CFC’s production by the year 2000.Carpooling is one option we can do to lower the amount of ozone depl...
