Chlorofluorocarbons (CFCs) - Manufactured substances used as coolants and computer-chip cleaners.
CFC (Chlorofluorocarbons)- Chlorine compounds formerly used in air conditioners, refrigerators, and spray cans; also called CFC's.
Climate-The average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area.
CFCs- short for "chlorofluorocarbons," a family of industrial gases. CFCs interfere with the natural cycle of ozone formation in the upper atmosphere, which acts as a barrier to harmful ultraviolet radiation.
chlorofluorocarbons A family of inert nontoxic and easily liquified chemicals used in refrigeration, air conditioning, packaging, and insulation or as solvents or aerosol propellants.
Greenhouse gases include carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and water vapor. Carbon dioxide, methane, and nitrous oxide have significant natural and human sources while only industries produce chlorofluorocarbons.
The threat posed to the atmosphere by chlorofluorocarbons (CFCs);
Acidification of lakes and forests in North America and Europe due to acid rain;
Global warming caused by build-up of greenhouse gases.

chlorofluorocarbons). Some of these organic compounds are sufficiently long-lived to allow their transport to the stratosphere, where they are destroyed by photolysis.
continent that typically develops annually between late August and early October, and generally ends in mid-November. Ozone thinning is attributed to the action of chlorine (Cl) liberated from a group of chemicals known as chlorofluorocarbons (CFCs).
Radioactive tracers such as 14C and 90Sr have been used to test models of stratospheric circulation. Certain atmospheric gases have also been used as tracers in ocean waters, for example, the chlorofluorocarbons.
