Study Finds Methane Leaks Negate Climate Benefits of Natural Gas

New York Times: The sign is ubiquitous on city buses around the country: "This bus runs on clean burning natural gas." But a surprising new report, to be published Friday in the journal Science, concludes that switching buses and trucks from traditional diesel fuel to natural gas could actually harm the planet's climate. Although burning natural gas as a transportation fuel produces 30 percent less planet-warming carbon dioxide emissions than burning diesel, the drilling and production of natural gas lead...

EPA Vastly Misjudges Methane Leaks, Study Confirms
2014-02-13 20:04:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: The federal government has underestimated methane emissions from the United States by 50 percent for the past 20 years, according to a comprehensive new study. Methane, also called natural gas, is a powerful but short-lived greenhouse gas. It lasts just nine years in Earth's atmosphere but is about 34 times more potent at trapping infrared radiation (the greenhouse effect) than carbon dioxide, which is more abundant and lasts longer. While methane spews into the sky from both natural sources,...

Methane burned vs. methane leaked: Frackings impact on climate change
2014-02-13 12:26:00| Climate Ark Climate Change & Global Warming Newsfeed
Ars Technica: Fracking--the use of hydraulic pressure to crack layers of shale that hold oil and natural gas--is controversial. Thats one thing we know about a debate that mainly focuses on what we dont know. The most common concern is the contamination of drinking water, either by the chemicals used in the fracking fluid or by liberated natural gas. And this issue has entered the public consciousness through media like the film Gasland and its imagery of flaming faucets--though almost 40 percent of people in...

Methane levels rising as funding cuts threaten monitoring network
2014-01-30 21:47:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Levels of methane, a climate-changing greenhouse gas, have been rising since 2007. But U.S. federal budget woes are shrinking the monitoring network that tracks greenhouse gases such as methane, which comes from sources as varied as fracking and cow farts. The National Oceanic and Atmospheric Administration (NOAA) monitors many potent greenhouse gases, such as methane, carbon dioxide and carbon monoxide, at observatories around the world. In the past six years, funding for part of the network ...

In this Nov. 26, 2012 file photo, Steve Lipsky demonstrates how his well water ignites when he puts a flame to the flowing well spigot outside his family's home in rural Parker County near Weatherford, Texas.
