Arctic Storms, Warming Temperatures Allowing More Methane To Surface

Underneath the Arctic Ocean sits a large reserve of methane, a potent greenhouse gas. Understanding how much of that is making it to the atmosphere is an important but relatively new area of research. The latest findings published on Sunday in Nature indicate that more could be escaping than previously thought, thanks in part to stormy weather.
The East Siberian Arctic Shelf is a shallow swath of land underneath the East Siberian Sea. It stretches for 2 million square miles and contains large deposits of methane hydrates, which are frozen deposits of highly concentrated methane.
When the hydrates melt, they turn into methane gas, a greenhouse gas that is 25 times more potent than carbon dioxide. Methane hydrates are found throughout the world's oceans but generally under hundreds of feet of water.
