On Sunday, the Danish Energy Agency announced that a series of leaks in natural gas pipelines running under the Baltic Sea had been stopped. But the rupture, preceded by multiple explosions last week, appears to be the single largest discharge of methane, an extremely potent greenhouse gas.
"It dwarfs the previous known leaks," says Ioannis Binietoglou, who works on monitoring methane emissions for the Clean Air Task Force, a non-profit environmental organization.
