Say bye to Polar Bears by 2100
Scientists predict that most polar bears will die out by the year 2100 because of global warming. Even if global warming is slowed, the loss of polar ice means most polar bears will still be seriously affected.
Polar bears are found in the far north, inside the Arctic Circle. Scientists believe there are about 25,000 polar bears left. Polar bears spend most of their lives on the ice which covers the Arctic seas.
As the world gets hotter because of manmade climate change, the Arctic is warming about twice as quickly as other places. This is making the ice cap smaller and thinner. Scientists say that by 2040, the ice would melt completely during the summers.
For polar bears, that’s a matter of life and death. Polar bears rely on the sea ice to travel, find mates, and hunt.
Seals are polar bears’ main food. Seals are rich in fat, which the polar bears need to survive in Arctic conditions.
Polar bears usually catch seals in places where the ice meets the water. To catch seals, the bears need to be able to walk and run across the ice. Polar bears are strong swimmers, but they’re not fast enough to catch seals in the water.
In the winter, when there’s ice, polar bears eat as much as possible, to store up energy. But these days, there’s less winter ice, meaning the bears have less area for hunting. So most polar bears won’t be able to eat enough in the winters to allow them to survive the summers.

The scientists believe that by 2040, polar bears will start dying out in southern areas of the Arctic, like Canada. In places like Alaska and Russia, the bears may start to die out by 2080.
