Shrinking Arctic glaciers are unearthing a new source of methane (IMAGE)
Caption
Glacier cave on Svalbard, Norway formed by large volumes of glacial meltwater that flows through it during summer. During winter, an extensive proglacial icing forms at its mouth and extends across the entire floodplain in front of the glacier, which is visible through the cave opening in the picture.
