Key properties of methane hydrates found in permafrost and on continental shelf illuminated
Posted by Washington Post: Juliet Eilperin on November 2nd, 2015
PhysOrg: Methane hydrates are a kind of ice that contains methane, and that form at certain depths under the sea or buried in permafrost. They can also form in pipelines that transport oil and gas, leading to clogging. Yet methane hydrates are nearly impossible to study because it is very hard to get samples, and the samples themselves are highly unstable in the laboratory.
A team of scientists from Norway, China and the Netherlands has now shown how the size of grains of the molecules that make up the...

Antarctica is gaining ice: NASA
Posted by Jagran Post: None Given on November 2nd, 2015
Jagran Post: According to the analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tonnes of ice a year from 1992 to 2001.The net gain slowed to 82 billion tonnes of ice per year between 2003 and 2008.
"We are essentially in agreement with other studies that show an increase in ice discharge in the Antarctic peninsula and the Thwaites and Pine Island region of West Antarctica," explained Jay Zwally, glaciologist with NASA Goddard Space Flight Centre in Greenbelt, Maryland. ...
Climate change claims a new victim: The slow demise of Califonia’s golden trout

Salon: Driving through the Owens Valley, a scenic 75-mile-long, U-shaped cul-de-sac on the east side of the Sierras, confirmed extremely dry conditions. California’s prolonged drought wasn’t just visible in the low stream flows, charred hillsides and snowless Sierra Nevada Mountains, but I could hear it. In the small town of Lone Pine, I overheard a man say: “I guess we won’t get to shower until next winter.” The water situation for local fish isn’t much better. For my journey – a day’s drive followed...
