The study, led by Marine Biological Laboratory (MBL) senior scientist Jerry Melillo, also predicts that increased fertilizer use for biofuels production will cause nitrous oxide emissions (N2O) to become more important than carbon losses, in terms of warming potential, by the end of the century. http://www.physorg.com/news175442925.html Space & Earth Thu, 22 Oct 2009 16:50:01 EST news175442925 (AP) -- India and China, both major polluters and crucial players in fighting global warming, agreed Wednesday to stand together on climate change issues at a major global conference later this year. http://www.physorg.com/news175339762.html Space & Earth Wed, 21 Oct 2009 11:30:03 EST news175339762 (PhysOrg.com) -- Consumers can have a major impact on the world`s efforts to reduce global warming, a major report has concluded. http://www.physorg.com/news174907366.html Space & Earth Fri, 16 Oct 2009 10:50:02 EST news174907366 A Japanese shipmaker said Thursday it planned to launch the world's first large electric ferry -- the latest innovation aimed at reducing greenhouse gas emissions. http://www.physorg.com/news174803759.html Technology Thu, 15 Oct 2009 05:36:39 EST news174803759 (PhysOrg.com) -- Anyone who has ever stepped barefoot onto blacktop pavement on a hot sunny day knows the phenomenon very well: Black surfaces absorb the sun's heat very efficiently, producing a toe-scorching surface. In the wintertime, that can be a good thing: A dark roof heats up in the sun and helps reduce your heating bill. But in summertime, it's definitely a bad thing: Your house gets even hotter, and your air conditioning has to work harder. In most places, the summertime penalty is greater than the wintertime gain, it turns out, so that's why many people, including U.S. Secretary of Energy Steven Chu, strongly advocate switching to white roofs. http://www.physorg.com/news174209373.html Technology Thu, 08 Oct 2009 08:30:13 EST news174209373 (AP) -- Proposed regulations would require power plants, factories and refineries to reduce greenhouse gases by installing the best available technology and improving energy efficiency whenever a facility is significantly changed or built. http://www.physorg.com/news173593742.html Space & Earth Thu, 01 Oct 2009 06:00:01 EST news173593742 (PhysOrg.com) -- Any calculation of the carbon footprint of a gallon of milk needs to include fuel used by tractors and trucks, as well as electricity consumed by milking machines and refrigerators.
