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

Construction is wrapping up on the Illusuak Cultural Centre, a striking wooden structure being built on the shores of the North Atlantic in Nain, Canada, to celebrate the region’s Inuit heritage.
- Uncovering Clues About the Arctic’s Past...by Megan Stewart on September 14, 2017 at 5:54 am
Arctic cruise passengers are being enlisted to help analyze logbooks kept by whalers nearly two centuries ago in an effort to better understand how sea ice in the region has shrunk.
- Proposed Port and Road in Canada’s Central...by Gloria Dickie on September 13, 2017 at 4:25 am
Nunavut is pushing for federal cash to help advance a mining project that would bring badly needed jobs to the territory’s northwest. But critics – including territorial government biologists – worry about the impact on a nearby barren-ground caribou herd.

- Humans did not cause woolly mammoths to go...on October 20, 2021 at 3:00 pm
For five million years, woolly mammoths roamed the earth until they vanished for good nearly 4,000 years ago—and scientists have finally proved why.
- 'Ray guns' let scientists use light instead of...on October 19, 2021 at 5:08 pm
In Star Trek, characters carry a little handheld device called a tricorder that they can point at objects to analyze and identify them. When the show's writers cooked up the idea in the 1960s, it was purely science fiction, but a new paper in New Phytologist takes the idea a step closer to reality. The researchers used a handheld device that looks a little like a ray gun to record how plant leaves on different Alaskan mountains reflect light. And, it turns out, different populations of plants […]
- Ancient driftwood tracks 500 years of Arctic...on October 19, 2021 at 5:07 pm
A new study reconstructs the path of frozen trees as they made their way across the Arctic Ocean over 500 years, giving scientists a unique look into changes in sea ice and currents over the last half millennium.
- Five facts to help you understand sea iceon October 19, 2021 at 12:40 pm
One way that scientists monitor climate change is through the measure of sea ice extent. Sea ice extent is the area of ice that covers the Arctic Ocean at a given time. Sea ice plays an important role in reflecting sunlight back into space, regulating ocean and air temperature, circulating ocean water, and maintaining animal habitats.
- Climate change and human pressure mean migration...on October 18, 2021 at 6:54 pm
Animals that migrate north to breed are being put at risk by ongoing climate change and increasing human pressure, losing earlier advantages for migration, declining in numbers and faring much worse than their resident counterparts, according to scientists writing in Trends in Ecology & Evolution.
