The Arctic region of the Earth is defined roughly as the area above 66 degrees north latitude and is largely a vast ocean covered by sea-ice, though that ice is being affected by global warming. The Arctic also includes much of Greenland, which is covered by a massive ice sheet, as well as the frozen tundra of Europe, Asia and North America. It has distinctive plants and animals found only there, such as the polar bear and the Arctic fox. Read below for the latest news and research from and on the Arctic, its ice and the life it supports.
