Thawing Arctic Could Set Off Methane Climate Bomb

Posted Apr 17, 08 4:08 PM CDT in Science & Health,  World 

(Newser) – Climate scientists meeting this week in Vienna are contemplating a terrible prospect—the release of billions of tons of methane gas from the Arctic Ocean, Der Spiegel reports. Methane, 20 times more damaging to the atmosphere than carbon dioxide, lies frozen in gas hydrates on the ocean floor, but rising global temperatures are loosening the ice’s grip.

Research has confirmed both that the methane-containing permafrost is warmer than it should be, and that water and air above the deposits are unusually saturated with methane. If released, the 540 billion tons of methane in the Arctic could drastically speed global warming, but, explains a researcher, "no one can say right now whether that will take years, decades or hundreds of years."

    It's Hard to Go Green With the Economy in the Red Bad days on Wall Street are bad news for environmentalists, too. The financial crisis doubles as a boon for critics of proposed greenhouse gas regulations, writes Margaret Kriz for Yale Environment 360. In its aftermath, politicians will be loath to pass laws that hike carbon-based fuel prices and wary of a "cap-and-trade" system that hands control of greenhouse gas emissions to commodities traders.

    Plans to Stop Global Warming Straight From Sci-Fi Novels Scientists worry humans might not curb carbon emissions in time to save the planet from irreversible harm, and some have suggested a radical concept called geo-engineering, the Economist reports. Once the stuff of science fiction, geo-engineering would combat global warming by manipulating the environment. While promising, critics warn ecological consequences could be disastrous and might encourage nations to continue using fossil fuels. More »

    NZ Farmers Gas About Sheep Flatulence Pollution Law In its quest to be the first carbon-neutral country, New Zealand is cracking down on methane emissions--and that means regulating the gas released by livestock, the Los Angeles Times reports. Farmers are worried a government proposal to fine them if their livestock exceed greenhouse-gas limits could leave many bankrupt—a particular problem as the world faces a food crisis. More »

    CO2 Catcher Could Slow Climate Change A team of American scientists says it's taken an important first step toward creating a so-called carbon scrubber that can rid greenhouse gases from the air, the Guardian reports. The scientists, led by a Columbia University physicist, have a prototype in the works that can suck a ton of carbon dioxide out of the air per day—and do so economically. More »

Bush outlined a plan to gradually rein in the growth of US greenhouse gas emissions by 2025—but rejected mandatory international carbon emissions caps unless they also bind China and India. More »
