Methane bubbles rise from Alaska's thawing permafrost

Ecologist Ted Schuur, walking the edge of Smith Lake in Alaska, watched bubbles of methane surface from the muck — gas produced by decomposing plants and animals once locked in frigid permafrost. The scene illustrates how thawing permafrost is releasing a potent heat-trapping gas, a feedback loop scientists warn could accelerate global warming as Arctic temperatures climb.
Why now: Rising Arctic thaw is putting permafrost methane emissions back in focus as a climate feedback concern.
