The Arctic is warming twice as fast as the rest of the world due to the albedo effect, causing loss of ice and increased absorption of heat. Polar bears may become extinct by 2100.
The Arctic is warming faster than the rest of the world, twice as fast on average. From the 1970s to the 2000s, however, the average temperature of parts of the Arctic increased 10 times as much as the world’s average temperature increase of 0.36 degrees Fahrenheit (0.2 degrees Celsius) per decade. The Arctic, the northernmost ice-covered region on Earth, is thought to be warming faster than the rest of the Earth due to the albedo effect, which occurs when loss of ice reduces the reflection of the sun’s heat back into space , and instead discovers bare water and rock that absorb and store the sun’s heat.

The amount of ice in the Arctic decreased by 14% from the 1970s to 2012.
Eight countries have regions that extend into the Arctic: Canada, Finland, Greenland, Iceland, Norway, Russia, Sweden and the United States.
Polar bears are found only in the Arctic, and conservationists predict they could be extinct by the year 2100 if the region continues to warm at the predicted rate.
