The study concerns the large deposits of methane (CH4) — a greenhouse gas over twenty times more potent than CO2 — known to be buried beneath the Arctic. Stockholm University researchers found that some of that methane is leaking, and even making it to the ocean’s surface. They called the discovery “somewhat of a surprise,” which, according to [climatologist and Arctic expert Jason] Box, doesn’t quite communicate its importance.

“The conventional thought is that the bubbles would be dissolved before they reached the surface and that microorganisms would consume that methane, and that’s normal,” Box went on. But if the plumes are making it to the surface, that’s a brand new source of heat-trapping gases that we need to worry about.
