Bombshell Study Finds Methane Emissions From Natural Gas Production Far Higher Than EPA Estimates

2013-11-27 14:19:00| Climate Ark Climate Change & Global Warming Newsfeed

AlterNet: A major new study blows up the whole notion of natural gas as a short-term bridge fuel to a carbon-free economy. Natural gas is mostly methane (CH4), a potent heat-trapping gas. If, as now seems likely, natural gas production systems leak 2.7% (or more), then gas-fired power loses its near-term advantage over coal and becomes more of a gangplank than a bridge. Worse, without a carbon price, some gas displaces renewable energy, further undercutting any benefit it might have had. Fifteen scientists...

US methane emissions exceed estimates, study finds

New York Times: Emissions of the greenhouse gas methane due to human activity were roughly 1.5 times greater in the United States in the middle of the last decade than prevailing estimates, according to a new analysis by 15 climate scientists published Monday in The Proceedings of the National Academy of Sciences. The analysis also said that methane discharges in Texas and Oklahoma, where oil and gas production was concentrated at the time, were 2.7 times greater than conventional estimates. Emissions from oil...

Methane Emissions In The US Reportedly Exceed EPA Estimates

2013-11-26 13:17:00| Climate Ark Climate Change & Global Warming Newsfeed

RedOrbit: The US Environmental Protection Agency (EPA) could be underestimating American methane emission levels by as much as 50 percent, according to new research appearing in this weeks early online edition of the journal Proceedings of the National Academy of Sciences. Carnegie Institution researchers, along with colleagues from the Lawrence Berkeley National Laboratory (Berkeley Lab), Harvard University and other institutions, used atmospheric methane observations from throughout North American in...
