For 30 years the Arctic has been melting at three times the global rateThe energy polar bears and narwhals use to survive in the rapidly warming Arctic has increased “three to fourfold” in recent decades, research claims, pushing them closer to extinction. For 30 years the Arctic has been melting at three times the global rate, eroding the hunting grounds of apex predators. Although polar bears and narwhals have long dominated the icy expanses of Greenland and northern Canada, they struggle to survive when pushed on to land. SponsoredBoth are ambush predators that use as little energy as possible while hunting, to retain fat reserves. Now, with sea ice shrinking by an estimated 13 per cent every decade, they are expending four times as much energy to catch their prey, according to a study published in the Journal
