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

Jordan Finally Phases out Ozone-depleting Chemicals

Green Prophet

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. Not a panacea: HCFCs also damage the ozone.

Reforestation for Ozone Removal: An Attractive Option

Nature Conservancy - Science

Ozone — together with fine particulates — contributes to smog formation. A new study documents the viability of reforestation for ozone control. So the idea of using forests — nature’s air cleaners — to remove smog-causing ozone and its precursors has great appeal.

Global Warming Impacting Ozone Recovery

Eco Friendly Daily

It has long been believed that ozone recovery and global warming did not overlap. It was found that greenhouse emissions are potentially preventing or slowing ozone recovery. The main way in which global warming is impacting ozone recovery is by changing wind patterns. Ozone is formed when air is moved through the area, but it has to be the proper speed for recovery to occur.

This year’s ozone hole could be the smallest it has been in 30 years

AGreenLiving

For decades, scientists have closely observed the ozone layer , which protects Earth from the sun’s harmful ultraviolet (UV) radiation. This year, just in time for World Ozone Day, the European Union’s Copernicus Atmosphere Monitoring Service (CAMS) announced the state of the ozone hole — its size is the smallest it has been in the past 30 years. Free radical oxygen atoms, being charged particles, readily react with other oxygen molecules to form ozone (O3).

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

Call for Climate Protection Under Ozone Treaty

Bangkok , Thailand , November 12, 2010 – At the 22nd annual meeting of the Montreal Protocol in Bangkok , a growing number of parties—expected to soon surpass a majority-- supported a proposal to use the ozone treaty to address super greenhouse gases known as hydrofluorocarbons or HFCs. Earlier this year the Federated States of Micronesia along with other vulnerable island countries proposed a formal amendment to the ozone treaty to phase down the production and use of HFCs.

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.

Ozone Treaty Lauded for Climate Protection

Green (Living) Review

by Michael Smith (Veshengro) Washington, DC – After almost 23 years in existence, the Montreal Protocol treaty is increasingly recognized for its success in saving the ozone layer – and in providing critical protection for the climate system. The Montreal Protocol was named as one of the five most effective pieces of environmental law, delivering a “one-two punch” for ozone and climate protection.

Record Ozone Depletion In Arctic This Year

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. Ozone loss, often in the form of ozone holes, have become common occurrences. In Antarctica, ozone holes occur each year. The same cannot be said for the Arctic, where the presence of ozone depletion varies.

Nitrous Oxide New Leader In Ozone Depletion

Eco Friendly Daily

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.

Antarctic Ozone Hole May Be On Way To Recovery

Eco Friendly Daily

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.

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.

The Other Climate Changers: Why Black Carbon and Ozone Also Matter

August 2009 – According to an essay published in the September/October issue of Foreign Affairs, reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields. The fact that reducing black carbon and ozone by 50 percent could offset the warming effect of up to three decades worth of CO2 emissions makes this a critical strategy to pursue.”
