Methane leaking in Utah suggests higher national rate
2013-08-07 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: A new study of the air above a natural gas field in Utah suggests that far more methane gas may be escaping into the atmosphere from drilling operations than previously estimated. The study, to be published in the journal Geophysical Research Letters, is the first to use an aircraft to directly sample the air downwind of natural gas and oil wells in order to calculate emissions of methane and contributors to smog. Most other studies to date have relied on various estimating techniques to determine...

Earthquakes May Contribute to Methane Leaks
2013-08-03 16:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: And here's another shuddering twist to the horror story that is climate change: even earthquakes may play a role. Large quantities of methane may have escaped during a violent earthquake that shook the floor of the Arabian Sea in 1945, according to German and Swiss researchers. David Fischer of the University of Bremen and colleagues from the Alfred Wegener Institute in Bremerhaven and the ETH in Zurich explored the region in a research ship in 2007, and began to examine cores of sediment from...

Arctic methane catastrophe scenario is based on new empirical observations
2013-08-02 17:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Ecologist: Last week, the journal Nature published a new paper warning of a $60 trillion price tag for a potential 50 Gigatonne methane pulse from the East Siberian Arctic Shelf (ESAS) over 10-50 years this century. The paper, however, prompted many to suggest that its core scenario - as Arctic permafrost thaws it could increasingly unleash dangerous quantities of methane from sub-ice methane hydrates in as quick as a decade - is implausible. The Washington Post's Jason Samenow argued that "almost everything...

Even Small Dams a Potential Hotbed for the Greenhouse Gas Methane
2013-07-31 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Dams, it turns out, may take an even greater toll on the environment than previously thought. Already scientists have shown that the world's 50,000 large dams are a source of methane, but a new study, published in the journal Environmental Science & Technology, provides new evidence that smaller dams are a problem as well. Methane is a known greenhouse gas with a warming effect 25 times more powerful than the headline-grabbing carbon dioxide. Among the largest contributors of emissions in the...
