(PhysOrg.com) -- "Blue haze," a common occurrence that appears over heavily forested areas around the world, is formed by natural emissions of chemicals, but human activities can worsen it to the point of affecting the world's weather and even cause potential climate problems, according to a study led by a Texas A&M University researcher. http://www.physorg.com/news174048123.html Space & Earth Tue, 06 Oct 2009 11:42:29 EST news174048123 (Santa Barbara, Calif.) -- Coastal marine ecosystems are at risk worldwide as a result of human activities, according to scientists at UC Santa Barbara who have recently published a study in the Journal of Conservation Letters. The authors have performed the first integrated analysis of all coastal areas of the world. http://www.physorg.com/news166365764.html Space & Earth Thu, 09 Jul 2009 13:43:23 EST news166365764 While the harsh winter pounding many areas of North America and Europe seemingly contradicts the fact that global warming continues unabated, a new survey finds consensus among scientists about the reality of climate change and its likely cause. http://www.physorg.com/news151609044.html Space & Earth Mon, 19 Jan 2009 17:39:04 EST news151609044 New research by the University of East Anglia (UEA) has demonstrated for the first time that human activity is responsible for significant warming in both polar regions. http://www.physorg.com/news144593037.html Space & Earth Thu, 30 Oct 2008 13:43:57 EST news144593037 (PhysOrg.com) -- Using a novel theoretical approach, researchers from NASA and other institutions have identified the common thread that determines how aerosols from human activity, like the particles from burning of vegetation and forests, influence cloud cover and ultimately affect climate. The study improves researchers` ability to predict whether aerosols will increase or decrease cloud cover. http://www.physorg.com/news137945726.html Space & Earth Thu, 14 Aug 2008 15:15:26 EST news137945726
