Study: Pipeline Would Result In More Global Warming Pollution
2014-08-10 21:51:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: A new study published Sunday by the journal Nature Climate Change concludes the much-debated Keystone XL pipeline could produce four times more global warming pollution than the State Department calculated this year. The proposed pipeline would carry oil from tar sands in western Canada to Texas, passing through western Nebraska. Researchers estimate it would increase world carbon by as much as 121 million tons a year compared with the department's estimate of 30 million tons. Study lead author...

Study: Keystone carbon pollution more than figured
2014-08-10 19:10:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: The much-debated Keystone XL pipeline could produce four times more global warming pollution than the State Department calculated earlier this year, a new study concludes. The U.S. estimates didn't take into account that the added oil from the pipeline would drop prices by about $3 a barrel, spurring consumption that would create more pollution, the researchers said. Outside experts not connected to the study gave it mixed reviews. The American Petroleum Institute found the study to be irrelevant...

Keystone XL pipeline may create more pollution than previously calculated
2014-08-10 17:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: A proposed pipeline from Canada to the United States may result in much higher greenhouse gas emissions than previously calculated as it could fuel greater oil consumption through higher production and lower prices, a study said Sunday. Researchers from the Stockholm Environment Institute used a mathematical model to estimate the Keystone XL pipelines potential for atmospheric pollution. Unlike calculations by the US State Department, they took into account a possible consumption rise in line...

Deep Pollution Cuts Needed by 2050 to Limit Global Warming
2014-08-07 22:09:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Deep cuts in greenhouse gas emissions of 40 to 70 percent by mid-century will be needed to avert the worst of global warming that is already harming all continents, a draft U.N. report showed. The 26-page draft, obtained by Reuters on Thursday, sums up three U.N. scientific reports published over the past year as a guide for almost 200 governments which are due to agree a deal to combat climate change at a summit in Paris in late 2015. It says existing national pledges to restrict greenhouse...

Mercury Pollution in Oceans Has Tripled Since Industrial Revolution, Study Says
2014-08-07 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Globally, oceans contain roughly 60,000 to 80,000 tons of mercury pollution, according to a report published this week in Nature detailing the first direct calculation of mercury pollution in the world's oceans. Ocean waters shallower than about 300 feet (100 meters) have tripled in mercury concentration since the Industrial Revolution, the study found, and mercury in the oceans as a whole has increased roughly 10 percent over pre-industrial times. North Atlantic waters showed the most obvious signs...
