Defusing the Methane Greenhouse Time Bomb: Scientific American

Defusing the Methane Greenhouse Time Bomb: Scientific American: "Methane trapped in Arctic ice (and elsewhere) could be rapidly released into the atmosphere as a result of global warming in a possible doomsday scenario for climate change, some scientists worry. After all, methane is 72 times more powerful as a greenhouse gas than carbon dioxide over a 20-year timescale. But research announced at the annual meeting of the American Geophysical Union this December suggests that marine microbes could at least partially defeat the methane 'time bomb' sitting at the bottom of the world's oceans."
