When it comes to climate change, good news is rare in the Arctic, where temperatures are rising faster than anywhere else on the globe. Enter methane gas, some 30 times more potent than carbon dioxide as a greenhouse gas. Is it possible that where methane bubbles to the surface from seafloor seeps, carbon dioxide is actually sucked up? New research off the coast of Svalbard says it’s true. Read about it in this article I published today in Science.
