*'''The Arctic''': the average temperature of the Arctic has increased 2.3°C since the 1970s. Ice dependent species such as narwhals, polar bears, and walruses are at increasing risk with shrinking sea ice cover. By 2100, polar bears could face starvation and reproductive failure even in far northern Canada. | *'''The Arctic''': the average temperature of the Arctic has increased 2.3°C since the 1970s.
