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...

Study Sees Path to Cutting Substantial American Natural Gas Leaks
2014-02-13 20:46:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: A policy analysis published in Science today examines 20 years of research on leakage from natural gas production and distribution systems in North America, including hydraulic fracturing, or fracking, and finds big opportunities to cut the worst leaks and a substantial climate benefit from a coal-to-gas switch, even accounting for higher leak rates. Gas leaks are not only wasteful and a source of regional air pollution but also contribute to global warming because the main constituent of nature...

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,...
