It’s Happened Before: Paleoclimate Study Shows Warming Oceans Could Lead to a Spike in Seabed Methane Emissions

The slowdown of a key ocean current could release methane that is frozen in layers of organic seabed sediments along some of the world’s coastlines, a new study shows. Cold temperatures and high pressure on sea floors currently sequester about one-sixth of the world’s methane, a potent but short-live...
