The world’s 'northernmost island' isn’t the first to be erased from the map.
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.
Giant viruses infect tiny algae in a rare epishelf lake in the Arctic Ocean that's one of the last of its kind.
The Siberian tundra will shrink even with ambitious greenhouse gas reductions. Without them, it could disappear altogether.
Simultaneous heat waves have hit the Arctic and Antarctica, raising temperatures by more than 50 degrees in parts of both polar regions.
A huge impact crater beneath the ice in Greenland dates back 58 million years, to when the Arctic was green and populated by hippo-like animals.
Located about 66.5 degrees north of the Equator lies the Arctic Circle — a line of latitude that outlines the border of Earth's northernmost region known as the Arctic.
