Four new gases found to be destroying ozone layer

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...

Four new gases that harm ozone layer found, despite bans: study

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 experts were trying to pinpoint industrial sources of tiny traces of the new gases, perhaps used in making pesticides or refrigerants, that were found in Greenland's ice and in air samples in Tasmania, Australia. The ozone layer shields the planet from damaging ultra-violet rays, which can cause...
Mysterious new man-made gases pose threat ozone layer

BBC: Scientists have identified four new man-made gases that are contributing to the depletion of the ozone layer. Two of the gases are accumulating at a rate that is causing concern among researchers. Worries over the growing ozone hole have seen the production of chlorofluorocarbon (CFC) gases restricted since the mid 1980s. But the precise origin of these new, similar substances remains a mystery, say scientists. Lying in the atmosphere, between 15 and 30km above the surface of the Earth,...
