Popis:

Have you ever seen a lake disappear? Permafrost is thawing across the Arctic, causing northern lands to sink or change shape. In Gates of the Arctic National Park, a bank of this lake thawed, allowing the Okokmilaga River to cut through and drain it to sea. Although it's the short-term impacts that are most noticeable to us, scientists are particularly concerned about what will happen as the frozen ground releases carbon dioxide and methane that were formerly stored under the surface.
