The Changing Arctic: How Animals Respond to Climate Change

The dramatic changes sweeping the Arctic as a result of global warming aren't just confined to melting sea ice and polar bears - a new study finds that the forces of climate change are propagating throughout the frigid north, producing different effects in each ecosystem with the upshot that the face of the Arctic may be forever altered.

"The Arctic as we know it may be a thing of the past," said Eric Post of Penn State, who led an international team that brought together research on the effects of climate change from ecosystems across the Arctic.
