A new study in November 2014 has found that polar bears in the Canadian Arctic Archipelago may be at risk of starvation and reproductive failure by the end of the 21st century.
Throughout the world, or at least the icy northern parts of it where polar bears actually live, the global population of polar bears is split into 19 separate sub-populations. Seven of these subpopulations reside in the Canadian Arctic Archipelago, comprising about a quarter of the world's total polar bears and almost a tenth of the global polar bear habitat.
It has previously been thought that the Canadian Arctic Archipelago and Greenland were the most likely places for Polar bears to survive global climate changes until the end of the 21st Century.
