It’s been a slow summer for polar bear news to hype, so we shouldn’t be surprised that a local report that polar bears this summer have descended on the town of Kaktovik, Alaska one week earlier than 2017 has morphed into an international story that makes a 2016 research report sound like this year’s news, with headlines trumpeting: “polar bear encounters are increasing” due to a longer open water period. Nevertheless, it was reported just two weeks ago that Alaska has not had a polar bear attack since 1993.
This is a particularly blatant example of how the media skew polar bear ‘news’ for public consumption, aided by scientists with a particular message to sell. Not surprisingly, a number of essential facts have been left out of this sensationized account, in part because the polar bear specialist the media consulted left those facts out of his statement. This is the sort of bias displayed by polar bear specialists that I discuss in my new book, The Polar Bear Catastrophe That Never Happened.

Sea ice in the Bering Sea this winter was said to be the lowest since the 1850s, largely driven by persistent winds from the south rather than the usual north winds although warm Pacific water was a factor early in the season (AIRC 2018). But what, if any, impact is this surprisingly low winter and spring ice cover likely to have on Chukchi Sea polar bear health and survival?
In fact, research on Chukchi Sea polar bears has included so few examples of individuals utilizing the Bering Sea in winter (Jan-March) and early spring (April-May) that any conclusions regarding an impact from this year’s sea ice conditions are likely to be invalid. In short, we don’t know what will happen since it has not happened before within living memory; the opinions of polar bear specialists must be taken with a grain of salt because so many of their previous assumptions have turned out to be wrong (Crockford 2017a,b, 2018), see here, here, and here. Seals, walrus and polar bears are much more flexible and resilent to changes in habitat conditions than most modern biologists give them credit for and consequently, it will be fascinating to see how the ice will change over the coming months and how the animals will respond.
