Arctic : of, relating to, or suitable for use at the north pole or the region near it arctic waters arctic animals arctic clothing (often capitalized) — Webster
Arctic is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost-containing tundra. Arctic seas contain seasonal sea ice in many places.
The Arctic region is a unique area among Earth’s ecosystems. For example, the cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. In recent years, Arctic sea ice decline has been caused by global warming. Life in the Arctic includes organisms living in the ice, zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. — Wikipedia

NOAA's annual report card on the Arctic, released today at the American Geophysical Union fall meeting in Washington, D.C., measures the changing climate of the polar region including warmer air and ocean temperatures and declines in sea-ice that are driving shifts in animal habitats. […]
How to get nuanced details at the top of the world
on December 12, 2018 at 2:32 pm
At the top of the world, once permanently frozen soil holds vast pools of carbon. Microbes could free that carbon under the right conditions. To predict how the Arctic will respond to seasonal freeze-thaw-growing conditions, scientists need data. They built a system that gathers detailed data. It obtained data for a year, took measurements deep underground, and monitored a wide area on the surface. The data revealed insights about tundra system behavior that might help accelerate long-term […]

Seventy percent of the current infrastructure in the Arctic has a high potential to be affected by thawing permafrost in the next 30 years. Even meeting the climate change targets of the Paris Agreement will not substantially reduce those projected impacts, according to a new study published in Nature Communications. […]

on December 10, 2018 at 8:00 pm
Microbes that provide natural fertilizer to the oceans by "fixing" nitrogen from the atmosphere into a form useable by other organisms were once thought to be limited to warm tropical and subtropical waters. Now, however, researchers have documented nitrogen fixation by an unusual type of cyanobacteria in the cold waters of the Bering and Chukchi Seas. […]
