Methane emissions will leap as Earth warms, study finds

The researchers’ findings suggest that methane emissions from freshwater systems will likely rise with the global temperature.

A new study announced by researchers at Princeton University found that, while carbon dioxide has been touted as the top dog of greenhouse gases, methane is approximately 30 times more potent as a heat-trapping atmospheric gas.

The new study appears in the latest issue of the journal Nature, which indicates that for each degree the Earth’s temperature increases, the amount of methane entering the atmosphere from microorganisms in lake sediment and freshwater wetlands will spike several times.  The rise in temperature will lead to a relative increase of methane emissions that will outpace that of carbon dioxide from these sources.
