Global Warming: The Greatest Threat to America's Arctic
 America's Arctic is on the front lines of global warming. The Arctic regions are warming at a rate that is about twice as fast as the rest of the world. Climate change poses a special danger to the region, where wildlife and nature have formed a delicate balance.
Now, this equilibrium is threatened by rising temperatures - a threat symbolized by the plight of the king of the north, the polar bear. The Intergovernmental Panel on Climate Change, set up by the United Nations to determine the impact of global warming, has found that the Arctic is likely the most vulnerable place on the planet to global warming impacts.
The severity of changes to habitat and impacts on wildlife that we are seeing in the Arctic now are an early warning of the impacts that other wildlife will face. Arctic and Antarctic species such as walrus, seals and penguins may soon find themselves in the same precarious situation as the polar bear.
