Fact #2

Is Global Warming affecting polar bears?

The chief threat to the polar bear is the loss of its sea ice habitat due to global warming. However, the polar bear is also stressed by other human activity, particularly oil and gas development activities in its habitat.

Potentially fatal to the polar bear, global warming has already left its mark on the species with smaller, less robust bears increasingly showing cannibalistic tendencies.The melting ice means not only shorter hunting seasons, but it also means the bears, which number some 20,000 to 25,000 worldwide, have to cross greater distances to reach their icy hunting grounds. Polar bears are dying because of the melting ice and many more have their health damaged. Climate change also appears to have altered the bears' behavioural patterns. Late 2004, four polar bears were found dead after drowning in the Beaufort Sea north of Alaska, likely the victims of a heavy sea. In this incident about 25 polar bears may have died.
