Study Warning of Massive Release of Methane From Melting Ice Not Without Critics

2013-07-29 23:31:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World News: Controversy has erupted over a recent study examining the greenhouse gases emitted through the melting of Arctic ice. Published in the journal Nature, the report warned that the estimated 50 gigatons of methane trapped inside the East Siberian Arctic Shelf is likely to be released within the next several decades as it thaws, causing an estimated $60 trillion in costs to countries everywhere due to resulting extreme weather. The authors of the study, which included Chris Hope and Peter Wadhams...

Methane Release From Earthquakes Feeds Global Warming

2013-07-29 19:18:00| Climate Ark Climate Change & Global Warming Newsfeed

RedOrbit: Michael Harper for redOrbit.com -- Your Universe Online In 1945 an 8.1 magnitude earthquake hit the northern Arabian Sea which released 7.4 million cubic meters of methane into the ocean and atmosphere. Now a team of scientists from the MARUM Institute at the University of Bremen, the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, and the ETH Zurich have concluded a study on this earthquake and believe similar temblors are also adding to the release of greenhouse gases....

Methane release from Arctic ice thaw an 'economic time bomb'

2013-07-26 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

ClimateWire: A massive release of methane from the Arctic seafloor would have catastrophic impacts on the world's economy, possibly costing $60 trillion or more because of associated problems such as sea-level rise and drought, according to a comment published yesterday in Nature. The $60 trillion -- roughly the size of the entire global economy last year -- considers a 50-gigaton belch of the greenhouse gas over a decadelong period from the East Siberian Sea, where scientists in recent years discovered perforations...

Methane Released by Arctic Melting Could Cost the World $60 Trillion in Climate Extremes

2013-07-25 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World News: The costs resulting from methane released by melting Arctic ice could equal $60 trillion, or roughly a year of global economic output, according to a paper published Wednesday in the journal Nature. Trapped within the East Siberian Arctic Shelf is an estimated 50 gigatons of the known greenhouse gas that is expected, according to the scientists, to be released either suddenly or gradually over the next half century based on how quickly the ice melts. Either way, the researchers, who hail from...

Arctic methane escape could cost $60 trillion

2013-07-25 17:41:00| Climate Ark Climate Change & Global Warming Newsfeed

Grist: An almighty belch is building up deep in the belly of the Arctic, and its going to cost the world a pretty penny when it rips. As the Arctic continues to melt, a 50-gigatonne reservoir of methane trapped in permafrost beneath the East Siberian Sea will be released - perhaps steadily over five decades or perhaps during one sudden grandfatherly burp - and that will cause an estimated $37 trillion to $60 trillion worth of damage. So say researchers in a commentary published Wednesday in the journal...
