“In late November, land-locked polar bears gather along the Hudson Bay to await the formation of Arctic ice so they can return to their seal-hunting grounds for the winter.” -- Nature's Best...
On average, Arctic sea ice has decreased by four percent per decade since the late 1970s. But at the same time, Antarctic ice has increased by 1 percent. Scientists are investigating why . More about...

Polar bears have evolved to survive in the Arctic with large, oar-like front paws for better swimming, as well as insulating blubber, and two layers of fur for the frigid temperatures. They rely on...
Scientists document a direct relationship between the extent of sea ice and polar bear survival. Future projected reductions in the extent of annual sea-ice due to global warming may result in the...
