Polar bears can’t survive on land , but they’re trying to. They have to . As sea ice melts due to climate change, Polar bears can’t rely on their traditional diet rich in fish, seals, and other marine-based food. The bears are turning to terrestrial foods like berries, birds and eggs, but they’re not as healthy and their survival rate is threatened by this new diet. “While it’s tempting to think that polar bears could survive by switching to a terrestrial diet, this paper establishes in no uncertain terms that land-based foods do not offer any hope of polar bear salvation,” said Steven Amstrup, the chief scientist for conservation group Polar Bears International (PBI) and co-author of the study, which was published Wednesday in Frontiers in Ecology and the Environment . Scientists with the USGS, PBI and Washington State University participated in the research. + Frontiers in Ecology and the Environment Via Al Jazeera Image via Real Distan Permalink | Add to del.icio.us | digg Post tags: arctic polar bears , baby polar bear , Canada polar bears , captive polar bears , global warming polar bears , loss of sea ice , polar bear diet , polar bear extinction , polar bear survival , polar bears , sea ice loss

Comments Off on Sea Ice Loss Blamed for Huge Spike in Alaskan Average Temperatures

Think Alaska is too cold for you ? Well, it seems that average fall temperatures there are increasing at a rapid rate. The most northerly community in the U.S., the town of Barrow, Alaska, has recorded an incredible 12.96 degree Fahrenheit (7.2 degrees Celsius) increase in its average October temperature over the 34 years from 1979 to 2012. The team from the University of Alaska Fairbanks who made the discovery also observed that the most notable average temperature increases in summer and fall correlated with  significant losses in sea ice concentrations.
