Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.

As climate change diminishes sea ice from coastal communities in the Arctic and the subarctic, researchers expect polar bears to range farther into the towns
Due to climate change in the Arctic, this polar region is expected to become "profoundly different" by 2050. [1]: 2321 The speed of change is "among the highest in the world", [1]: 2321 with the rate of warming being 3-4 times faster than the global average. [2][3][4][5] This warming has already resulted in the profound Arctic sea ice decline ...
