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 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...

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,...

Why the jury's still out on the risk of Arctic methane catastrophe

2013-09-05 21:30:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: About a week ago, climate scientist Michael Tobis wrote a critique of my 'Seven facts about the Arctic methane time bomb' following a twitter exchange with him and Chris Colose, author of an article at Skeptical Science arguing that the core scenario of a new Nature paper by Gail Whiteman et. al on the economic costs of Arctic climate change is extremely unlikely. Much of this debate kicked off because the said Nature paper advances a hypothetical scenario for an abrupt Arctic methane release...
