Four New Man-Made Gases Found That Harm Ozone Layer, Scientists Say

Green (Living) Review

OSLO, March 9 (Reuters) - Scientists have detected four new man-made gases that damage the Earth''s protective ozone layer, despite bans on almost all production of similar gases under a 1987 treaty, a study showed on Sunday. The ozone layer shields the planet from damaging ultra-violet rays, which can cause skin cancer and eye cataracts, and has been recovering after a phase-out of damaging chemicals under the U.N.''s

What’s The State of The Ozone Layer Today?

Eco Friendly Daily

Discovery of the depletion of the ozone layer was a watershed moment in the ecological timeline of our world. Ozone became synonymous with pollution and chemicals like CFCs (Chloro Fluro Carbons) which used to be staple chemical ingredients of a lot of products from refrigerators to fire extinguishers. Its less than desirable effect on the Earth’s protective sheath, the ozone layer was well highlighted.

Arctic Ozone Layer Destruction Reaches Unprecedented Level


In December 2010 NIWA announced the Antarctic ozone hole was the smallest it had been in the past five years. Now comes news from the World Meteorological Organisation (WMO) that the depletion of the ozone layer has reached what the WMO describes as an “unprecedented level” between December 2010 to March 2011, thanks to the ongoing presence of ozone-depleting substances in the atmosphere.

Hole in ozone layer protects Antarctic from over-effect of warming

I have been saying for years (and I am no scientist), ever since the “discovery” of this hole in the ozone layer that it may have always been there and that it may be a kind of safety valve for Planet Earth. But the scientific community not even considered that possibility and immediately claimed that CFCs were responsible for this hole and that this might be the beginning of the ozone layer being destroyed entirely by those gases.

The How to Guide to Save our Ozone Layer


In 1985 international action was taken to stop the release of Chlorofluorocarbons (CFC’s), after the realisation of their harmful effects on our atmosphere, specifically the whole that was created above Antarctica. Recent reports indicate that the whole in the Ozone Layer is starting to close because of the stance against CFC’s.

Not a panacea: HCFCs also damage the ozone.

One of the biggest indicators of climate change are ozone holes, zones where the ozone that forms the protective layer of Earth’s atmosphere are too thin to be protective anymore. The reactions that convert less reactive chemicals into ozone-destroying ones take place in the polar vortex. The journal nature has confirmed that conditions this year have created the ozone hole in the North Pole. This creates reactions that are the cause of ozone breakdown.

The Montreal Protocol, which came to be in 1987, limited ozone-depleting compounds. The researchers found that nitrous oxide is becoming the leading man-made reason for ozone loss.

Study: Despite Ban, CFCs May Still Be In Use

CFCs were known to be a major factor in the thinning ozone layer. According to a recent study of CFCs in the atmosphere, CFCs may in fact still be in use in one or more places in the world. The scientists sampled the atmosphere at 115,000 feet. Through use of mass spectrometers, the scientists were able to determine the specific types of chlorine atoms in the atmosphere.

In 1987 the Montreal Protocol began the phasing out of substances which are harmful to the planet’s ozone.

Ozone holes, which are areas with substantially low numbers of ozone, have become common knowledge on this planet. Increased UV radiation from the lowered ozone also can lead to troubles with crop production.
