Scientists say the ozone layer is recovering

Green (Living) Review

WASHINGTON (AP) — Earth''s protective ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. For the first time in 35 years, scientists were able to confirm a statistically significant and sustained increase in stratospheric ozone, which shields the planet from solar radiation that causes skin cancer, crop damage and other problems. green living ozone layer

Massive Hole in Arctic Ozone Layer

Sustainability Ninja

A recent study released by NASA has shown a massive loss of the protective ozone layer above the Arctic last winter and spring. The loss of the ozone in that region is caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The study, published online today in the journal Nature, discovered that the loss of ozone in the Arctic this year was comparable to the one in the Antarctic. Eco News arctic ozone loss

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?

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.

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).

Recent reports indicate that the whole in the Ozone Layer is starting to close because of the stance against CFC’s. 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. NASA are hopeful the hole will closed be 2050 and late last year reported the whole is the smallest it’s been in over two decades.

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.

Arctic Ozone Hole Biggest on Record

A huge hole that appeared in the Earth's protective ozone layer above the Arctic in 2011 was the largest recorded in the Northern Hemisphere, scientists have reported.

Since the 1980s, everyone in the Southern Hemisphere has been aware of the hole in the ozone every summer above Antarctica.

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, as these compounds decreased due to the agreement, nitrous oxide was increasingly harmful to the ozone.

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.

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.
