Scientists have reported the presence of previously unknown sources of methane—a greenhouse gas some 25 times more powerful than CO2 at trapping heat—bubbling up from the Arctic Ocean seafloor north of Norway. Gradual warming of a regional current has caused temperature-sensitive methane hydrate below the seabed to break down and discharge the gas, the researchers say.
