Scientists Warn Quake Risk From Fracking Operations
2014-05-02 09:46:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: Underground disposal of wastewater from fracking may pose a much greater risk of causing dangerous earthquakes than previously believed, particularly in areas of the U.S. Southwest and Midwest where earthquake faults have not been mapped extensively, seismology researchers said at a conference Thursday. Worse yet, scientists are not yet able to predict which wastewater injection sites are likely to pose risks to buildings or critical structures such as power plants, and do not yet know what operators...

Fracking opponents pack two St. Tammany meetings
2014-05-01 23:57:00| Climate Ark Climate Change & Global Warming Newsfeed
Advocate: People packed two venues in St. Tammany Parish on Thursday night, waving signs, cheering anti-oil-drilling comments and jeering drilling advocates. The impetus for the public outcry was the proposal by Helis Energy, before the Louisiana commissioner of conservation, to drill a single oil well on a 960-acre tract near Interstate 12 and La. 1088 in the Mandeville area. Helis is proposing to drill a 13,000-foot-deep well near Lakeshore High School. The well would utilize an oil-extraction method...

Scientists: 'Fracking' should be part of assessing earthquake hazards
2014-05-01 15:33:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: Researchers with the US Geological Survey are developing an estimate of earthquake hazards that for the first time includes hazards posed from earthquakes triggered or suspected to have been triggered by waste-water disposal wells used by the oil and gas industries. The effort stems from two earthquakes in 2011 that topped magnitude 5 and were suspected to have been triggered by waste-water injection one in southern Colorado, at magnitude 5.3, and another in Oklahoma, at magnitude 5.7. The Oklahoma...

Top Canadian scientists urge cautious approach to fracking until more known of impact
2014-05-01 13:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Canadian Press: A report from a panel of top Canadian scientists is urging a go-slow approach to the booming industry of hydraulic natural gas fracking. So little is known about the long-term impacts of extracting gas by fracturing rock beds with high-pressure fluids that scientists and regulators need to start now to understand how to develop the resource safely and cleanly, said co-author Rick Chalaturnyk, an engineering professor at the University of Alberta. Perhaps cautionary is the right philosophy,...
Fracking Gets A Few New Rules
2014-05-01 07:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Michigan Radio Network: The Department of Environmental Quality has updated its rules for hydraulic fracturing. The controversial process, also called fracking, involves pumping water, sand and chemicals into a drilled oil or gas well, then sealing and pressurizing it to crack layers of rock far below the surface and release gas and oil. DEQ officials say the changes will increase information available to concerned residents and keep better track of water impacts. The DEQ's new rules, revised for the first time since...
