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. He co-chaired the every-four-years ozone assessment by 300 scientists, released at the United Nations.

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.

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

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.

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.

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.

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.”
