Methane emissions in Barnett greater than estimated, study says

2015-07-08 03:46:40| Waste Management - Topix.net

An image in a Texas Commission on Environmental Quality report taken in 2009 shows an infrared camera view of emissions from a natural gas storage tank in Decatur. Methane emissions from natural gas operations in North Texas' Barnett Shale are 50 percent higher than estimates by the federal government would indicate, according to a series of studies published Tuesday in the scientific journal Environmental Science & Technology .

New study reveals mechanism regulating methane emissions in freshwater wetlands

2015-06-30 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: Though they occupy a small fraction of Earth's surface, freshwater wetlands are the largest natural source of methane going into the atmosphere. New research from the University of Georgia identifies an unexpected process that acts as a key gatekeeper regulating methane emissions from these freshwater environments. The study, published in Nature Communications by Samantha Joye and colleagues, describes how high rates of anaerobic methane oxidation, a process once considered insignificant in these...

Which oil and gas companies are leaking the most methane?

2015-06-29 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

ClimateWire: Over the years, ConocoPhillips -- an energy company so rich that it earns as much in a year as Croatia -- has positioned itself as a good guy among its peers when it comes to greenhouse gas pollution. It is a member of a U.N.-led initiative to reduce emissions of methane, a potent greenhouse gas that is the primary component of natural gas. In the United States, it is a longtime participator in U.S. EPA's voluntary program to curb methane leaks. In January, Ryan Lance, CEO of ConocoPhillips, said...

Exceptional view of deep Arctic Ocean methane seeps

2015-06-22 17:03:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: Close to 30,000 high definition images of the deep Arctic Ocean floor were captured on a recent research cruise. This gives researchers insight into the most remote sites of natural methane release in the world. Over a course of 12 days Dr. Giuliana Panieri and her colleagues from Centre for Arctic Gas Hydrate, Environment and Climate collected images from seven areas of known methane release in the Arctic Ocean. One of them was Vestnesa Ridge, with over 1000 active seep sites at the depth of over...
