Shale Gas Wells Feature Massive Methane Levels

2014-04-16 03:59:00| Climate Ark Climate Change & Global Warming Newsfeed

Softpedia: Natural gas burning as it seeps through the ground to the surface For several years, the public opinion has been battered with the idea that natural gas is much cleaner to exploit than coal, because it contains less carbon. A new study by researchers at the Cornell University and the Purdue University demonstrates that significant levels of the dangerous greenhouse gas methane can be found above shale gas wells. Carbon dioxide is currently the most pervasive greenhouse gas (GHG) in the atmosphere,...

Huge Methane Leaks Add Doubt on Gas as Bridge Fuel

2014-04-16 00:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate Central: Natural gas as a means to produce electricity is being hailed by the Intergovernmental Panel on Climate Change as the fuel that can act as a "bridge" between carbon-heavy coal and zero-carbon renewables, helping to reduce humans' impact on the climate. The idea is that burning natural gas involves fewer greenhouse gas emissions than burning coal. The IPCC in its Working Group III report says natural gas as a bridge fuel will only be effective if few gases escape into the atmosphere during natural...

EPA Focuses on Fracking, Leaks and More to Further Obamas Methane Plan

2014-04-15 21:16:00| Climate Ark Climate Change & Global Warming Newsfeed

EcoWatch: The U.S. Environmental Protection Agency (EPA) on Tuesday released five technical papers as the first step to enacting President Barack Obama`s recent plan to reduce methane emissions. The five white papers address different emissions sources and mitigation techniques regarding methane and volatile organic compounds. The sources of focus are fracking, leaks, compressors, liquid removal and pneumatic devices. "[The] EPA will use the papers, along with the input we receive from the peer reviewers...

Purdue and Cornell Researchers Reveal Up to 1,000 Times More Methane Emissions Than Estimated

2014-04-15 17:24:00| Climate Ark Climate Change & Global Warming Newsfeed

EcoWatch: Because natural gas has less carbon than dirty coal, gas producers and even the United Nations Intergovernmental Panel on Climate Change have applauded it as a cleaner alternative. Hopefully, a joint study from researchers at two universities will change that. Purdue and Cornell universities on Monday released a study in the Proceedings of the National Academy of Sciences of the United States of America with data on higher-than-expected methane levels found above shale gas wells. The researchers...

EPA Drastically Underestimates Methane Released at Drilling Sites

2014-04-15 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed

LA Times: Drilling operations at several natural gas wells in southwestern Pennsylvania released methane into the atmosphere at rates that were 100 to 1,000 times greater than federal regulators had estimated, new research shows. Using a plane that was specially equipped to measure greenhouse gas emissions in the air, scientists found that drilling activities at seven well pads in the booming Marcellus shale formation emitted 34 grams of methane per second, on average. The Environmental Protection Agency...
