Do These Bubbles Signal the Start of Rapid Climate Change?

Do These Bubbles Signal the Start of Rapid Climate Change?

by John Light

First it was mysterious craters appearing in Siberia — possibly the result of the Earth belching methane as permafrost thaws and collapses.

Then scientists observed methane gas bubbling to the surface from the sea floor in the Arctic Ocean, where for eons it lay trapped in a flammable slush. The researchers who discovered the plumes — a joint team of Americans, Swedes and Russians on an expedition called the SWERUS-C3 — suspect the methane is escaping due to an influx of warmer water from the Atlantic Ocean, which, in turn, could be tied to climate change.
The release of methane on a large scale has long worried scientists. The greenhouse gas is 20 times more damaging to the Earth over a 100-year period than CO2, and is even more potent in the short term. Should the deposits trapped within the Arctic escape into the air, it could kick off a highly destructive climate feedback loop: The methane would cause rapid warming, which would melt more of the Arctic, which would release more methane, which would cause more warming.
