The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
The main predators of the tundra are the polar bear, the Arctic wolf, and the Arctic fox. They all have thick white coats that help them blend into their environment and stalk prey. [ 5 ] The polar bear spends the majority of its time out on the ice hunting seals and sometimes when small rodents are scarce on land the Arctic fox will follow the ...

The climate of the region is known to be intensely cold during the year due to its extreme polar location. [5] The area has tundra, Arctic vegetation, [3] glaciers, and, for most of the year, is covered in thick blankets of snow and ice. [5] It is home to various species of plants, and land, air and marine animals. [6]

This was the Arctic’s second-hottest year on record, according to a new NOAA report. The tundra has become a source of emissions, rather than a carbon sink, the authors said. The Arctic is ...
