News About The Ozone Layer 19-NOV-09 en-us Paris, France (ESA) Sep 22, 2009 - 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.]]> Greenbelt MD (SPX) Sep 18, 2009 - 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.]]> Geneva (AFP) Sept 16, 2009 - The World Meteorological Organisation said Wednesday that the ozone hole is expected to be smaller in 2009 than a year ago.]]> Paris (AFP) Sept 6, 2009 - Climate change will disrupt Earth's precious ozone layer, boosting ultraviolet (UV) radiation in the deep southern hemisphere and reducing UV in far northern latitudes, a study warned on Sunday.]]> Washington (AFP) Aug 31, 2009 - Nitrous oxide emissions caused by human activity have become the largest contributor to ozone depletion and are likely to remain so for the rest of the 21st century, a US study has concluded.]]> Greenbelt MD (SPX) Apr 14, 2009 - 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.]]> Greenbelt MD (SPX) Mar 23, 2009 - The year is 2065. Nearly two-thirds of Earth's ozone is gone - not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole.]]> Stockholm (AFP) March 3, 2009 - The ozone layer over Sweden was thicker in February than it has been in decades, the Swedish meteorological institute SMHI said on Tuesday.]]> Washington DC (SPX) Nov 07, 2008 - The Antarctic ozone hole reached its annual maximum on Sept. 12, 2008, stretching over 27 million kilometers, or 10.5 square miles. The area of the ozone hole is calculated as an average of the daily areas for Sept. 21-30 from observations from the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite.]]> Boulder CO (SPX) Oct 14, 2008 - Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes. The research, by scientists at the National Center for Atmospheric Research (NCAR), focused on California wildfires in 2007, finding that they repeatedly caused ground-level ozone to spike to unhealthy levels across a broad area, including much of rural California as well as neighboring Nevada.]]>
