If polar bears had any clue of the scale of speculation about the extinction threat they are facing due to climate change, they would have probably said, "you're kidding, right?"
If you think statistics are a pointer towards the growth or decline of a species, it will be interesting to have a look at the estimates published in a 2008 report by U.S. Senate Environment and Public Works Committee.
"The U.S. Fish and Wildlife Service estimates that the polar bear population is currently at 20,000 to 25,000 bears, up from as low as 5,000-10,000 bears in the 1950s and 1960s. A 2002 U.S. Geological Survey of wildlife in the Arctic Refuge Coastal Plain noted that the polar bear populations 'may now be near historic highs,'" it read.
