Deep under the icy waters of the Arctic, Russian scientists have discovered vast stores of methane, the potent greenhouse gas, far worse than CO2. The scientists sampled the waters along the East Siberian Arctic Shelf, and discovered that the methane that was once dormant at the sea floor is starting bubble up to the surface in enormous plumes. As the climate warms in the Arctic, the sea ice retreats, the sunlight penetrates the water, and the frozen sea floor thaws, causing the release of methane in a gaseous state. The Russian team found over 100 sites where large quantities of methane were released, indicating accelerated Arctic warming into the future.
