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.
Three of North Greenland's eight enormous ice shelves have already undergone complete collapse.
Scientists simulated ancient viruses to see what impact they would have on the environment. While most had few consequences, 1% were capable of killing their hosts and disrupting ecosystems.
The ancient nematode has lain dormant in a fossilized squirrel burrow since the late Pleistocene, revealing that these worms can survive for tens of thousands of years longer than thought.
Newly released drone footage confirms that the Batagay crater in Siberia continues to grow in size.
NASA's Aqua satellite spotted giant ice swirls stretching for hundreds of miles in the Sea of Okhotsk off Russia's P'yagina Peninsula.
The permafrost inside the Batagay crater is the second-oldest ever found on Earth and scientists are using it to reconstruct the planet's ancient climate.
Giant viruses infect tiny algae in a rare epishelf lake in the Arctic Ocean that's one of the last of its kind.
