The World Meteorological Organisation said Wednesday that the ozone hole is expected to be smaller in 2009 than a year ago. http://www.physorg.com/news172311361.html Space & Earth Wed, 16 Sep 2009 09:18:41 EST news172311361 (PhysOrg.com) -- The annual ozone hole has started developing over the South Pole, and it appears that it will be comparable to ozone depletions over the past decade. This composite image from September 10 depicts ozone concentrations in Dobson units, with purple and blues depicting severe deficits of ozone. http://www.physorg.com/news172335679.html Space & Earth Wed, 16 Sep 2009 16:20:02 EST news172335679 Nitrous oxide has now become the largest ozone-depleting substance emitted through human activities, and is expected to remain the largest throughout the 21st century, NOAA scientists say in a new study. http://www.physorg.com/news170603626.html Space & Earth Thu, 27 Aug 2009 15:40:01 EST news170603626 Depending on its altitude, ozone can be either friend or foe. Thanks to new research led by The University of Western Ontario, scientists will now have a better understanding of ozone, its origin and the role - good or bad - it plays in polluting our atmosphere. http://www.physorg.com/news113743515.html Space & Earth Thu, 08 Nov 2007 11:25:15 EST news113743515 New Zealanders are being warned to cover up and use sun block as a patch of thin ozone layer moves across the country. http://www.physorg.com/news78309259.html Space & Earth Sun, 24 Sep 2006 09:34:19 EST news78309259 The growing popularity of air conditioning in India and southern China has some scientists worried about the impact on the ozone layer. http://www.physorg.com/news91460054.html Space & Earth Fri, 23 Feb 2007 13:34:14 EST news91460054 The global market for rocket launches may require more stringent regulation in order to prevent significant damage to Earth's stratospheric ozone layer in the decades to come, according to a new study by researchers in California and Colorado. http://www.physorg.com/news157731737.html Space & Earth Tue, 31 Mar 2009 15:23:16 EST news157731737 The pollution that causes ozone depletion is declining, but the warming of the atmosphere will see a global thinning of the ozone layer, says a U.N. panel. http://www.physorg.com/news11404.html Space & Earth Sat, 04 Mar 2006 05:30:04 EST news11404 (PhysOrg.com) -- Physicists at the University of Toronto have discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada. Other regions of the Earth, such as the tropics and Antarctica, will instead face increasing levels of UV radiation. http://www.physorg.com/news171462048.html Space & Earth Sun, 06 Sep 2009 13:21:18 EST news171462048 (PhysOrg.com) -- Earth's ozone layer should eventually recover from the unintended destruction brought on by the use of chlorofluorocarbons (CFCs) and similar ozone-depleting chemicals in the 20th century. But new research by NASA scientists suggests the ozone layer of the future is unlikely to look much like the past because greenhouse gases are changing the dynamics of the atmosphere. http://www.physorg.com/news158591820.html Space & Earth Fri, 10 Apr 2009 14:17:56 EST news158591820 Some of the substances that are helping to avert the destruction of the ozone layer could increasingly contribute to climate warming, according to scientists from NOAA's Earth System Research Laboratory and their colleagues in a new study published today in the journal Proceedings of the National Academy of Sciences. http://www.physorg.com/news164914625.html Space & Earth Mon, 22 Jun 2009 18:38:11 EST news164914625 A much-discussed idea to offset global warming by injecting sulfate particles into the stratosphere would have a drastic impact on Earth's protective ozone layer, new research concludes. The study, led by Simone Tilmes of the National Center for Atmospheric Research (NCAR), warns that such an approach might delay the recovery of the Antarctic ozone hole by decades and cause significant ozone loss over the Arctic. http://www.physorg.com/news128266565.html Space & Earth Thu, 24 Apr 2008 14:36:05 EST news128266565 By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale - and the findings look promising. http://www.physorg.com/news172755429.html Space & Earth Mon, 21 Sep 2009 12:50:01 EST news172755429 There is more to the snowflake than its ability to delight schoolchildren and snarl traffic. http://www.physorg.com/news179416713.html Chemistry Mon, 07 Dec 2009 14:26:57 EST news179416713 (PhysOrg.com) -- On July 15, 2004, NASA's Aura spacecraft launched from California's Vandenberg Air Force Base on a mission to study Earth's ozone layer, air quality and climate. Aura's data are helping scientists address global climate change issues such as global warming; the global transport, distribution and chemistry of polluted air; and ozone depletion in the stratosphere, the layer of Earth's atmosphere that extends from roughly 15 to 50 kilometers (10 to 30 miles) in altitude. http://www.physorg.com/news166979911.html Space & Earth Thu, 16 Jul 2009 16:21:19 EST news166979911
