Oceanic methane seeps and climate warming

A study that tracked the exchange of carbon dioxide (CO2) and methane between the sea surface and the atmosphere finds that CO2 uptake by the ocean was enhanced above oceanic methane seeps near Svalbard, Norway, relative to surrounding waters, and estimates that the atmospheric cooling effect associated with atmospheric CO2 removal was up to 231 times greater than the atmospheric warming effect linked to oceanic methane emissions, suggesting that areas of methane seepage may represent greenhouse gas sinks. - Read at PNAS
