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.

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

Asthma Inhalers and the Ozone Layer

Eco Friendly Daily

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.

Record Ozone Depletion In Arctic This Year

Eco Friendly Daily

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, the agreement enabled the ozone to slowly recover.

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.

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

Green (Living) Review

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.

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).

Inequality between rich and poor nations helps fuel a climate of mistrust and sabotages efforts to secure a climate deal

For developed nations the more global environmental issues such as climate change, ozone depletion and habitat loss are higher up on their priority list. The ozone layer crisis during the 1980’s is a good example of how the world can come together to combat global environmental issues. India was equally tough in their negotiations and their environment minister said in a statement that: “We didn’t destroy the layer. Photo credit: america.gov.

Study Links Ozone Hole to Climate Change

Green (Living) Review

While previous work has shown that the ozone hole is changing the atmospheric flow in the high latitudes, the Columbia Engineering paper, “Impact of Polar Ozone Depletion on Subtropical Precipitation,” demonstrates that the ozone hole is able to influence the tropical circulation and increase rainfall at low latitudes in the Southern Hemisphere. The ozone hole is a big player in the climate system!"

Daily Demand and Supply: I'm all for environmental regulations until my AC stops working and I need Freon

In 1987, the Montreal Protocol, an international treaty to address atmospheric ozone depletion, established timelines for the phasing out of Chloroflourocarbons (CFCs) and Hydrochloroflourocarbons (HCFCs).  said the annual allowances have decreased faster than the market demand for R-22, which has depleted inventory across the supply chain.

HFCs are chemicals are potential substitutes for ozone-depleting and climate-warming CFCs and HCFCs currently being phased out under the Montreal Protocol treaty to protect the ozone layer. Although they don’t harm the ozone layer, HFCs are powerful climate warming gases and their emissions are expected to rise sharply over the next few decades without aggressive action, significantly contributing to climate change.

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.

They face a number of threats, including climate change, ozone depletion, habitat loss and degradation, chemical, nutrient, and hard waste pollution, fisheries, collisions with ships, capture for aquariums, and harassment by whale watching boats. Depletion of the ozone layer has allowed more ultraviolet radiation to reach the surface of the ocean, where it has killed krill, the major food of baleen whales and the basis of the ocean’s food chain.
