Fracking Emits Less Methane than Estimated Says Study
2013-09-17 00:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Fracked natural gas wells leak much less methane -- a potent climate change-driving greenhouse gas -- at certain points during the production process than previous studies and the Environmental Protection Agency have estimated, according to a University of Texas study released Monday. Methane is one of the chief components of natural gas locked up in underground shale formations -- the target of a natural gas drilling boom stretching from Pennsylvania to the Rockies and beyond. Energy companies...

Study: Natural gas industry can cut fracking emissions

USA Today: The booming U.S. production of natural gas can be less environmentally harmful than estimated if gas companies take certain steps to cut greenhouse gas emissions, says a major study Monday that was done with industry participation. The study, billed as the first to measure the actual emissions of heat-trapping methane from natural gas wells, finds these emissions are slightly less than the most recent national estimate by the U.S. Environmental Protection Agency. In some cases, the emissions were...

Study Revises Estimate of Methane Leaks from U.S. Fracking Fields
2013-09-16 23:15:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Environmental controls designed to prevent leaks of methane from newly drilled natural gas wells are effective, a study has found -- but emissions from existing wells in production are much higher than previously believed. The findings, reported today in the Proceedings of the National Academy of Sciences, add to a burgeoning debate over the climate impact of replacing oil- and coal-fired power plants with those fuelled by natural gas. Significant leaks of heat-trapping methane from natural gas...

Oil and fracking chemicals spill into Colorados floodwaters
2013-09-16 21:49:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: Heavy rains returned to Colorado on Sunday and hampered rescue efforts after last week`s flash floods. The confirmed death toll has risen to seven, and hundreds are still unaccounted for. An estimated 1,500 homes are destroyed. Some 1,000 people in Larimer County, north of Boulder, were awaiting airlifts that never came on Sunday - they were called off because of the foul weather. The floods have also triggered other problems that have gotten a lot less media attention: Fracking infrastructure...

Study Delivers Good, Bad News on Methane Leaks from Fracking Operations
2013-09-16 18:24:00| Climate Ark Climate Change & Global Warming Newsfeed
InsideClimate: A long-awaited study led by the University of Texas at Austin shows that methane emissions from natural gas drilling sites are about 10 percent lower than recent estimates by the U.S. Environmental Protection Agency. The research adds fresh fuel to the debate over whether natural gas is less carbon-intensive than coal. Although natural gas power plants emit smaller quantities of greenhouse gases than coal-fired plants, the production and distribution of natural gas release large amounts of methane,...
