Shrinking sea ice forces Polar Bears into "marathon" swims as population declines

Polar Bears Undertaking Marathon Swims, Populations Declining Rapidly as Sea Ice Disappears

The polar bear population in the Beaufort Sea area have declined 50% or more in the last decade. Nearly 7 in 10 of the 100 bears the researchers monitored swam at least 49 km (30.44 mi) in 2012. That’s up 25% from 2007.

As climate change advances in the Arctic, polar bear populations continue to suffer

Polar Bears are Suffering from the Ravages of Climate Change

The polar bear is emblematic of the Canadian wilderness, but as an apex predator, they are also one of the species most at risk from climate change. The Arctic is experiencing the effects of global warming more than any other place on Earth. Temperatures in the Arctic are rising at almost twice the rate of the rest of the world,…

Feedback Accelerates Arctic Ice Melt – Canada, Alaska Most Pronounced

Scientists at NASA and the National Snow and Ice Data Center published research last week in the Journal of Geophysical Research based on satellite microwave data of seasonal Arctic ice thaw from 1970 to 2009. The study indicates the seasonal Arctic sea ice melt season is now about 20 days longer than it was 30 years ago. The growing season…
