Methane levels in the atmosphere are now higher than at any point in the past 800,000 years, according to a recent report from the Intergovernmental Panel on Climate Change.

Methane is a powerful greenhouse gas, and although it breaks down faster than carbon dioxide, it's about 25 times more effective at trapping heat in the atmosphere.

In the United States, much of that methane is emitted by livestock.

Consider This cohost Steve Brown speaks with WBUR reporter Walter Wuthmann about a group of New England scientists who are trying to cut those methane emissions by feeding the cows seaweed.
