Four polar bear carcases have been found floating off the coast of Alaska, proof that that the animals are drowning because climate change is causing the Arctic ice shelf to melt. The mammals now have to swim up to 60 miles across open sea to find food because the ice floes they normally feed off are becoming smaller and drifting farther apart. Although the bears are strong swimmers, they are adapted to swimming close to shore, and the sea journeys have left them exhausted and vulnerable to hypothermia.
The Intergovernmental Panel on Climate Change has confirmed that human-induced climate change is a reality. It can no longer be dismissed as a theoretical, academic concept nor a politically motivated doomsday prophecy. In the Arctic, climate change impacts will be seen earlier are more dramatically than elsewhere in the world. WWF
A new report, "Impacts of a Warming Arctic: Arctic Climate Impact Assessment," is
the result of four years of work by 300 scientists. And the results aren't pretty.
They tell us that the Arctic is warming far more rapidly than anyone thought, and
at nearly twice the rate as the rest of the world.
For the first time we're hearing projections of an Arctic without ice not on a timescale of hundreds of years, but within 70. Greenpeace
