A Polar Bear Myth That Just Won't Quit

Like seals popping up at breathing holes, the myth that polar bear numbers are increasing has resurfaced on some blog posts and news shows, with claims that polar bears have increased from 5,000 in the 1960s to 20,000 to 25,000 today. But the truth is that scientists have no idea how many bears there were in the 1960s—only guesses—because the first population studies had not yet been done.

Journalist Peter Dykstra reports on the history of this oft-repeated myth in his article, Magic Number: A Sketchy "Fact" About Polar Bears Keeps Going and Going and Going, and our chief scientist, Dr. Steven C. Amstrup, addresses the question on our website.
