Microbes possibly feeding on the remains of an ancient forest may be generating billions of tons of methane deep beneath Antarctic ice, a new study suggests.
The amount of this greenhouse gas — which would exist in the form of a frozen latticelike substance called methane hydrate — lurking beneath the ice sheet rivals that stored in the world's oceans, the researchers said.
If the ice sheet collapses, the greenhouse gas could be released into the atmosphere and dramatically worsen global warming, researchers warn in a study published in the Aug. 30 issue of the journal Nature.
