When world leaders meet in Copenhagen in December to hash out a treaty limiting carbon dioxide emissions, they should begin planning a future summit to address other pollutants - from soot to ozone - that don't remain in the atmosphere as long as carbon dioxide, but nevertheless are major contributors to global warming. http://www.physorg.com/news175442630.html Space & Earth Thu, 22 Oct 2009 15:30:01 EST news175442630 In his neatly ordered lab at DuPont, chemist Ming Zheng slides open a glass cabinet and removes a flask of soot that could have been swept from someone's fireplace. http://www.physorg.com/news168613815.html Nanotechnology Tue, 04 Aug 2009 14:11:31 EST news168613815 The area of forest burnt by wildfires in the United States is set to increase by over 50% by 2050, according to research by climate scientists. http://www.physorg.com/news168010385.html Space & Earth Tue, 28 Jul 2009 14:40:29 EST news168010385 Particulate pollution thought to be holding climate change in check by reflecting sunlight instead enhances warming when combined with airborne soot, a new study has found. http://www.physorg.com/news165517024.html Space & Earth Mon, 29 Jun 2009 20:00:02 EST news165517024 (AP) -- Sixty percent of Americans live in areas with unhealthy air pollution levels, despite a growing green movement and more stringent laws aimed at improving air quality, the American Lung Association said in a report released Wednesday. http://www.physorg.com/news160207575.html Space & Earth Wed, 29 Apr 2009 07:11:29 EST news160207575 Soot from pollution causes winter snowpacks to warm, shrink and warm some more. This continuous cycle sends snowmelt streaming down mountains as much as a month early, a new study finds. How pollution affects a mountain range's natural water reservoirs is important for water resource managers in the western United States and Canada who plan for hydroelectricity generation, fisheries and farming. http://www.physorg.com/news150983710.html Space & Earth Mon, 12 Jan 2009 11:55:10 EST news150983710 Tugboats puff out more soot for the amount of fuel used than other commercial vessels, and large cargo ships emit more than twice as much soot as previously estimated, according to the first extensive study of commercial vessel soot emissions. Scientists from NOAA and the University of Colorado conducted the study and present their findings in the July 11 issue of the journal Geophysical Research Letters. http://www.physorg.com/news134820787.html Space & Earth Wed, 09 Jul 2008 11:13:07 EST news134820787
