Methane meltdown: The Arctic timebomb that could cost us $60trn
2013-07-25 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: The sudden release from the melting Arctic of vast quantities of methane a greenhouse gas at least 20 times more potent than carbon dioxide is an economic time-bomb that could explode at a cost of $60 trillion (40tr) to the global economy, a study has concluded. A scientific assessment of the costs associated with the release of Arctic methane into the atmosphere has found that the financial consequences to the world would almost equal the entire global economic output of one year. Scientists...
Arctic methane breach an 'economic time bomb.'
2013-07-25 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: Massive leakage of methane from thawing shoreline in the Arctic would devastate the world's climate and economy, a trio of scientists warned on Wednesday. Billions of tonnes of this potent greenhouse gas are locked in the shallow frozen shelf of the Arctic Ocean, which warms when summer sea ice retreats as a result of the greenhouse-gas effect, they said in a contribution to Nature. The team modelled what would happen if 50 billion tonnes, or gigatonnes (Gt), of methane escaped over a decade...

Cost of Arctic methane release could be 'size of global economy', experts warn
2013-07-24 20:04:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Researchers have warned of an "economic time-bomb" in the Arctic, following a ground-breaking analysis of the likely cost of methane emissions in the region. Economic modelling shows that the methane emissions caused by shrinking sea ice from just one area of the Arctic could come with a global price tag of 60 trillion dollars -- the size of the world economy in 2012. Writing in a Comment piece in the journal, Nature, academics argue that a significant release of methane from thawing permafrost...

Ice free Arctic in two years heralds methane catastrophe - scientist
2013-07-24 16:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: A new paper in the journal Nature argues that the release of a 50 Gigatonne (Gt) methane pulse from thawing Arctic permafrost could destabilise the climate system and trigger costs as high as the value of the entire world's GDP. The East Siberian Arctic Shelf's (ESAS) reservoir of methane gas hydrates could be released slowly over 50 years or "catastrophically fast" in a matter of decades if not even one decade the researchers said. Not everyone agrees that the paper's scenario of a catastrophic...
Huge methane belch in Arctic could cost $60 trillion
2013-07-24 12:59:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: A sudden methane burp in the Arctic could set the world back a colossal $60 trillion. Billions of tonnes of the greenhouse gas methane are trapped just below the surface of the East Siberian Arctic shelf. Melting means the area is poised to deliver a giant gaseous belch at any moment" - one that could bring global warming forward 35 years and cost the equivalent of almost a year's global GDP. These are the conclusions of the first systematic analysis of the economic cost of Arctic melting,...
