'Glacial fracking': A hidden source of Arctic greenhouse gas emissions

Arctic glaciers are leaking significant amounts of methane, a potent greenhouse gas. Glacial melt rivers and groundwater springs are transporting large volumes of methane from beneath the ice to the atmosphere. This previously unrecognized process could contribute to Arctic climate feedbacks, accelerating global warming.
