Ozone: Good Up High, Bad Nearby
Layer? Ozone occurs naturally in the stratosphere and is produced and destroyed at a constant rate. But this "good" ozone is gradually being destroyed by manmade chemicals called chlorofluorocarbons (CFCs), halons, and other ozone depleting substances (used in coolants, foaming agents, fire extinguishers, and solvents). These ozone depleting substances degrade slowly and can remain intact for ...

Coral Reefs
In the atmosphere some of the long-wave radiation is absorbed by certain gases called greenhouse gases. These include carbon dioxide (CO2), chlorofluorocarbons (CFCs), methane (CH4), nitrous oxide (N20), tropospheric ozone (O3), and water vapor. Each molecule of greenhouse gas becomes energized by the long-wave radiation. The energized molecules of ...

situation
However, after studying other possible causes for ozone depletion, the international community came to a consensus that certain manmade chemical compounds called chlorofluorocarbons (CFCs), were largely responsible for the ozone loss. As a result, the Montreal Protocol was adopted in 1987, calling for the worldwide elimination of CFCs and other ozone- ...

Equity Watch - Global Environmental Government Unit - Centre for Science and Environment (CSE)
There naturally exist in the atmosphere gases such as carbon dioxide (CO2), methane (Ch4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), and water vapour. They are called greenhouse gases. Thats because they act like a blanket spread over the earths surface, helping to keep it warm. The temperatures experienced near the earths surface, and therefore ...

(H20), carbon dioxide (CO2), ozone (O3), nitrous oxide (N2O), methane (CH4), and chlorofluorocarbons (CFCs)." (GSFC/NASA). Some gases absorb and trap more heat per molecule than others. The greenhouse effect provides a blanket of warmth enveloping earth, which we need. Otherwise we would freeze! Without a natural ...

Special Pollutant: Chlorofluorocarbons (CFCs) - Minnesota Pollution Control Agency
(UV-B) rays generated from the sun. There is a substantial amount of scientific evidence that suggests man-made compounds such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs) and halons destroy ozone in the upper atmosphere (stratosphere). Decreased concentration of stratospheric ozone allows increased levels of UV-B rays to reach the earth's ...

Ozone depletion in the upper atmosphere is the result of human-produced chemicals, such as chlorofluorocarbons (CFCs) and halons. Depletion is especially severe over Antarctica in spring, causing the highly publicised " ... 1987 and subsequently strengthened, has led to phase out of most CFC and halon use. However, CFCs and halons last for a long time in the atmosphere, so it will be some decades ...

The Ecobeetle Eco-Calendar - This day in Environmental History
Consumer Product Safety Division jointly announced a ban on the manufacture of nearly all aerosol products containing chlorofluorocarbons (CFCs). The ban did not include CFCs used in refrigerators and air conditioners and those used in the production of plastic foams. 1994 - The government of Ecuador ended the harvest season on sea cucumbers around the ...

Why the banning of Chlorofluorocarbons is paranoia.
European countries and the U.S. have agreed to phase out the use of chlorofluorocarbons (CFCs) by the year 2000 brings before us yet again the questionable theory that CFCs ... to make a sound decision regarding the phasing out of our best refrigerants. Remember, before CFCs, toxic ammonia and sulfur dioxide were used in our home refrigerators. « The Nature Of Environmentalism » « ...
