The chief threat to the polar bear is the loss of its sea ice habitat due to global warming. As suggested by its specific scientific name (Ursus maritimus), the polar bear is actually a marine mammal that spends far more time at sea than it does on land.
Will the polar bear eventually go extinct, morph into another species, or something else? What does the science really say?
As with most species that is or will be vulnerable to climate change, habitat is key in the case of the polar bear. Climate change is warming the Arctic along with the rest of the planet — and in the Arctic, that means sea ice is melting.
SEA ICE IS CRUCIAL FOR POLAR BEARS SURVIVAL.
Polar Bears are going extinct because of ongoing and potential loss of their sea ice environment resulting from climate change; polar bears were listed as a helpless species in the US under the Endangered Species. The survival and the protection of the polar bear habitat are urgent issues.
HOW ARE POLAR BEARS BEING IMPACTED BY GLOBAL WARMING?
- Population sizes decreasing – At present the current best estimates among international scientist’s places the world’s polar bear population at20,000 to 25,000
- Sea ice platforms moving farther apart and swimming conditions more dangerous – The retreat of ice has implications beyond the obvious habitat loss. Remaining ice is farther from shore, making it less accessible. The larger gap of open water between the ice and land also contributes to rougher wave conditions, making the bears’ swim from shore to sea ice more hazardous.
- Fewer hunting opportunities and increased scarcity of food – Polar Bear are dying because of not getting enough Seals to eat. Without sea ice, polar bears cannot catch enough seals to eat — and without enough seals to eat, they are unlikely to gain enough weight to survive their autumn to summer
Most scientists agree that these trends spell likely trouble for polar bears. But now Polar Bears are protected by the endangered Species Act, and it is hoped by conservation biologists that by taking greater steps to reduce greenhouse gas emissions we will be able to slow down global warming and help save vital polar bear habitat.
