Happy International Polar Bear Day!

Science reporter Deborah Netburn talked to the chief scientist for Polar Bears International, the conservation group that founded International Polar Bear Day, about ways people can help polar bears. Number one on the group’s list: turn your thermostat down a few degrees.

Polar bears remain a threatened species

The U.S. Circuit Court of Appeals decided to keep polar bears protected by broad federal measures Friday,

The court rejected the argument that the 25,000 remaining polar bears, most of which live in relatively stable populations, were perfectly fine without “threatened species” status. But many scientists worry that the effects of climate change on the Arctic climate could prove dangerous for the remaining bears.

And it looks like polar bears may remain on that list for the foreseeable future, according to Kassie Siegel of the Center for Biological Diversity.

"So for practical purposes, the listing of the polar bear is final, and really no longer under any serious threat from these challenges."
