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...

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,...
Drop in population of Gulf of Maine baby lobsters puzzles scientists
2014-04-23 23:54:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The number of baby lobsters in the Gulf of Maine has dropped by half since 2007, a phenomenon that has puzzled scientists as the population of adult lobsters remains near a record high, contributing to robust catches. Scientists note that baby lobsters take eight years to reach harvestable size, meaning the dip could yet be felt by the state's 4,200 lobstermen, who last year hauled in a record catch worth $365 million, representing nearly 70 percent of Maine's total seafood harvest. Despite the...

Scientists Use Krypton Dating to Estimate Antarctic Ice's Age
2014-04-22 11:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Researchers have used radiometric krypton-dating to find the age of ancient Antarctic ice. The new technique can be used to hunt and date old ice samples. Finding old ice samples is important because it helps scientists construct and fine-tune ancient climate models. The latest krypton-based dating technique shows that the ice from Taylor Glacier in Antarctica is around 120,000 years old. Just so that we are clear, researchers here are using krypton- the noble gas and not kryptonite, which...
