EU parliament backs law to curb "super" greenhouse gases

Reuters: The European Parliament on Wednesday backed a law to curb the use of "super" greenhouse gases used in fridges and air conditioners, which have a global warming potential thousands of times greater than carbon dioxide. Lawmakers meeting in Strasbourg, France voted 644 to 19 in favour of a European Commission proposal to cut the use of climate-harming hydrofluorocarbons, known as HFCs or 'F-gases', by 79 percent below average 2009-2012 levels by 2030. "Today marks the beginning of the end for...

Scientists Find Four New Ozone-Depleting Gases
2014-03-10 12:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Researchers have found four new man-made gases that are depleting the ozone blanket. University of East Anglia researchers say that more than 74,000 metric tons of these gases have been released in the atmosphere. The gases include three new chlorofluorocarbons (CFCs) and one hydrochlorofluorocarbon (HCFC). For the study, researchers looked at air samples obtained from polar firm snow- which is like a catalogue of atmospheric conditions that existed a century ago. They compared these air samples...

Four new gases found to be destroying ozone layer
2014-03-10 12:04:00| Climate Ark Climate Change & Global Warming Newsfeed
BusinessGreen: The ozone layer over Antarctica is being attacked by four previously unidentified man-made gases, scientists from the University of East Anglia (UAE) have warned. New research published in Nature Geoscience yesterday found that more than 74,000 tonnes of three new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been released into the atmosphere, despite a ban on CFCs since 1989. UEA's team, led by Dr Johannes Laube, compared samples of air from 100 years ago, 36 years...

Scientists discover four new manmade ozone-depleting gases
2014-03-10 11:46:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Four new manmade gases, possibly derived from chemicals in insecticides and solvents, have been found to be damaging the ozone layer, which helps filter harmful ultraviolet rays. Three of the gases are chlorofluorocarbons (CFCs) and one is a hydrochlorofluorocarbon (HCFC). Two are accumulating at worrying rates in the atmosphere, but scientists have not identified the exact sources yet. The identification of these four new gases is very worrying as they will contribute to the destruction of...
