Polar Bear Peril: The Dangers of Longer Swims (New York Times)

Amid the debate over the effects of climate change comes a new study from researchers at the United States Geological Survey and the World Wildlife Fund.

Their findings indicate Polar Bears are indeed having to swim longer distances – in one case, 427 miles – to find sea ice, leaving them at greater risk of drowning and impacting their ability to reproduce, given the imposition of greater energy expenditures.
