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 s 1987 Montreal Protocol.

Asthma Inhalers and the Ozone Layer

Asthma sufferers are doing their part to decrease the amount of ozone depleting substances in the air whether they want to or not. Because of the far-reaching Montreal Protocol on Substances that Deplete the Ozone Layer, the emergency albuterol inhalers asthma patients have used for years are changing, and the old versions won’t be produced or sold past December 2008. The Montreal Protocol doesn’t just apply to inhalers, either.

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.

Same urgent cooperation needed on Climate Change as the Ozone Layer

Green (Living) Review

by Michael Smith (Veshengro) The Chartered Institution of Water and Environmental Management (CIWEM) is urging the international community to cooperate on climate change in the same way that they united for the protection of the ozone layer. In the 1980s, computer models predicted a global disaster if no action was taken to protect the ozone layer against synthetic ozone-depleting chemicals such as chlorofluorocarbons (CFCs).

Jordan Finally Phases out Ozone-depleting Chemicals

The Hashemite Kingdom of Jordan has wrapped up a national phase-out of all central cooling systems using chlorofluorocarbons (CFC), reports the Jordan Times : ”Jordan’s program for phasing out the use of CFCs, aimed at disposing 1500 tons of the harmful substance, was achieved one year ahead of schedule”, said Ghazi Odat, Director of the Ministry of Environment’s ozone project. Jordan is a signatory to the Montreal Protocol.

Arctic Ozone Hole’s Effect on Food Supplies this Winter

Green Blog

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.

New Carbon Market Rules for Destroying Ozone-Depleting Chemicals Open the Door for Major Climate Benefits

Washington, DC, February 2010 – Billions of tons of ozone-destroying and climate-warming chemicals currently contained in unwanted stockpiles and discarded equipment will leak into the atmosphere if not recovered and destroyed. But new rules on ozone-depleting substance destruction adopted by a carbon market offset registry, the Climate Action Reserve, could jumpstart new projects in both the U.S.

World's Most Successful Environmental Treaty Turns 25


The treaty is the Montreal Protocol and its success has avoided one of the most severe global environmental threats the world has ever faced—the destruction of the stratospheric ozone by chlorofluorocarbons (CFCs). “The Montreal Protocol has phased out nearly 100 kinds of CFCs and related fluorinated gases by 98%, an astonishing record by any measure,” stated Durwood Zaelke, President of the Institute for Governance and Sustainable Development.

Nitrous Oxide New Leader In Ozone Depletion

Their study revolved around ozone-depleting compounds, particularly nitrous oxide. The ozone was once a highly debated global concern that created the Montreal Protocol. 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. However, the agreement enabled the ozone to slowly recover.

Study: Despite Ban, CFCs May Still Be In Use

The Montreal Protocol was an agreement by governments across the globe to phase out and eventually ban the use of chlorofluorocarbons (CFCs). CFCs were known to be a major factor in the thinning ozone layer. Scientists believe that the presence of such CFCs is causing the ozone to not heal as quickly as estimated prior. CFCs were commonly found in aerosol propellants, refrigerants, air conditioning and fire extinguishers, amongst other products.

In 1987, the Montreal Protocol aimed for eliminating the use of chlorofluorocarbons (CFCs) due to the destruction the chemicals were causing to the environment and ozone layer.

The same cannot be said for the Arctic, where the presence of ozone depletion varies.

Antarctic Ozone Hole May Be On Way To Recovery

In 1987 the Montreal Protocol began the phasing out of substances which are harmful to the planet’s ozone. When CFCs are exposed to ultraviolet radiation they subsequently cause the release of chlorine atoms which work to destroy ozone molecules. 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.
