 Arctic

The 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), Northern Canada (Canada), Finland, Greenland (Kingdom of Denmark), Iceland, Norway, Russia and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost (permanently frozen underground ice)-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.

The hypothesis of an Arctic ice shelf was first put forward in the 1970s, but there was limited evidence supporting it. When ice reaches the seafloor it causes erosion. Although ice scour marks have been found on the Arctic seafloor previously, it was argued whether the keels of icebergs or an ice ...

High above the Arctic Circle, far from the footprint of human civilization, a significant indication of human-induced climate change has manifested in Lake Hazen, the largest lake by volume north of the Arctic Circle. The lake and surrounding glacial environment are experiencing rapid change as the ...

WASHINGTON (REUTERS) - Bowhead whales, the black filter-feeding giants of the Arctic that can live for 200 years devouring tons of tiny marine creatures, boast another remarkable quality. Their unique underwater songs make them wonderful "jazz" artists. Researchers on Tuesday (April 3) said they ...
Canadian scientists thought one of the Arctic's largest lakes could handle small changes in climate, but it turns out that's not the case.

Sea ice in the Arctic grew to its annual maximum extent – the largest ice-covered area of the year – last week. NASA scientists said 2018 joined 2015, 2016 and 2017 as the four lowest maximum extents on record. The sea ice covering the Arctic Ocean melts and regrows in an annual cycle, thickening and ...
As Arctic sea ice breaks up, it's starting to move southward faster, creating new and unexpected hazards. More icebergs calving off Greenland add to the threat.
(CNN) – The size of the Arctic Sea ice is extremely low for a fourth year in a row. The Northern Arctic Sea ice grows and shrinks depending on the season. But NASA says the ice cover reached its maximum size for the year last week. And it's the second-lowest on record, not much larger than the all-time low ...
Benjamin Vidmar lives and works in one of the most northern towns in the world. He is trying to grow food for the town of about 2,000 people.

In fact, through most of the winter, the Arctic was on track to have its worst period ever. The only reason this winter ultimately didn't break yet another record for low sea ice was that as cooler air in recent weeks allowed ice to reform, the increase near Japan in the Sea of Okhotsk was significant enough to ...
Seeing the Northern Lights is an unforgettable experience, but standing outside in the cold waiting for them to appear is pretty tedious. So, what if you could enjoy the Aurora Borealis from the comfort of your bed? And what if your bed could be moved, depending on where the Aurora was strongest?
“We've probably known for 100 years that as the climate warms up in response to loading the atmosphere with greenhouse gases, we would see the changes first in the Arctic,” said Mark Serreze, director of the National Snow and Ice Data Center in Boulder, Colo., which issued the new data. “This is what ...
WASHINGTON (AP) - U.S. government scientists say ice covering the Arctic ocean reached its second lowest extent on record this winter. For most of the winter, sea ice in the Arctic was at record lows, but cold March winds helped the ice expand just beyond the low set in 2017. Scientists from National ...
The general decline of sea ice is related to the warming Arctic climate, but the peculiar lack of ice this winter is related to unusual weather and ocean currents the past few months.
