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

Climate change may affect ecological interactions...
on February 22, 2019 at 12:09 pm
With herbivores, omnivores, carnivores, insectivores, frugivores, scavengers and decomposers, Earth's ecosystems function within a vast web of interactions among plants, animals, insects, fungi and microorganisms. A fundamental part of this web resides in the equilibrium of the food chain that links predators to herbivores and regulates plant production on our planet. […]

Predicting climate change
on February 18, 2019 at 2:40 pm
Thomas Crowther has identified long-disappeared forests available for restoration across the world, finding that there is room for an additional 1.2 trillion new trees globally that could absorb more carbon than human emissions each year. Crowther also describes data from thousands of soil samples collected by local scientists that reveal the world's Arctic and sub-Arctic regions store most of the world's carbon. But the warming of these ecosystems is causing the release of this soil carbon, a […]
Tiny satellites reveal water dynamics in...
on February 14, 2019 at 9:21 pm
Using an army of small satellites, researchers have shown that water levels in small lakes across northern Canada and Alaska are far more variable during the summer than previously thought. The findings, published in Geophysical Research Letters, could have implications for how scientists calculate the natural greenhouse gas emissions from these northern lakes. […]
