The giant crabs are coming. And they're hungry.

Researchers at the University of North Carolina's (UNC) Aquarium Research Center have found that higher atmospheric levels of carbon dioxide — a greenhouse gas that's linked to global warming — are also causing crabs to grow to bigger, faster and stronger, according to the Washington Post.

As the oceans absorb significant amounts of atmospheric carbon dioxide, ocean water becomes more acidic and carbon-rich, and these higher levels of carbon are giving rise to the supersized crabs.

Billions of Tons of Methane Lurk Beneath Antarctic Ice

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.
