In the year 2006, the winter in the northern hemisphere had the lowest level of ice in three decades which was just 14.6 million square kilometres. The average recorded from 1979 to 2000 was 15.9 million kilometres. Given this situation, there is a posing threat to the polar bears that are dependent on the ice to live.
As the sea ice in the Arctic Ocean continue to shrink combined with untimely ice melt, the living conditions to the world’s largest bears become unfavourable. Aside from being adapted to survive cold temperatures and to move across icy water and snow, the polar bears hunt seals – their primary food, on the surface of the sea ice. They spend most of their time on the icy water or along the edge of the frozen sea to hunt for seals. Although majority of the polar bears are born on land, they are also considered maritime bears because of their preference to stay at sea or basin coastlines for long hours.
In a related study of one of the scientists from the Polar Bears International, it was revealed that one of the warmest temperatures recorded in history was in 2010. As a result of this, there was delay and weak ice formation in the Arctic.
The question still remains, will the coming weather conditions in the Arctic continue to remain unfavourable for the polar bears? Will they also disappear in the future?
