Livestock and methane: What's a consumer to do?

2014-06-15 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Free Press: The public debate over climate-change agents has focused recently on coal, shale oil and fracked natural gas - fossil fuels, all. Vermonters might draw vague solace from knowing that these disputed resources, and the key battles being waged over how and whether to contain production, are mostly out of their hands - and out of state. Yet Vermont has a trademark resource that's also, indisputably, a source of greenhouse gas emissions: livestock. Cows, sheep and other animals put out methane, a potent...

Abandoned oil wells spouting significant levels of methane, study finds

2014-06-14 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Tyee: A Princeton University study has found that leaks from abandoned oil and gas wellbores pose not only a risk to groundwater, but represent a growing threat to the climate. Between 200,000 and 970,000 abandoned wells in the state of Pennsylvania likely account for four to seven per cent of estimated man-made methane emissions in that jurisdiction, a source previously not accounted for, the study says. Pennsylvania, much like Alberta in Canada, is the oldest oil and gas producer in the United...

EPA rules ignore methane

Living on Earth: Climate protection advocates have applauded the EPA's recent power plant regulations, but environmental lawyer Bill Snape tells host Steve Curwood, the new rules don't deal with methane, and that could be a serious problem for the climate. Transcript CURWOOD: From the Jennifer and Ted Stanley Studios in Boston and PRI, this is Living on Earth. I'm Steve Curwood. As the evidence of human-induced climate disruption becomes more stark, many nations are cutting global warming emissions, including...

Leaking natural gas wells in Canada spew methane: Report

2014-06-09 15:38:03| Climate Ark Climate Change & Global Warming Newsfeed

Vancouver Sun: Up to 10 per cent of B.C. natural gas wells are leaking and some have become super-emitters of methane, which is an environmental and health concern, says a new report. Wells can leak from their drill holes as gas can travel along gaps and cracks in the cement that is used to plug the hole between the steel pipe and the underground rock surfaces, says the 69-page report authored by three University of Waterloo scientists. The commonly overlooked problem is potentially a greater environmental...

Mitigate the methane

2014-05-18 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Pittsburgh Post-Gazette: First, the bad news. There is broad agreement that methane emissions from natural gas development in Pennsylvania and other states are a serious problem. Methane is a highly potent greenhouse gas and, absent adequate controls, methane leaks across the natural gas supply chain could undo many of the potential environmental benefits natural gas can have over other fossil fuels like coal. But there appears to be a disconnect about what is being done today to assess and regulate these emissions in the...
