Media and USGS biologist sensationalize recent report of a polar bear encounter in Alaska

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.

Not predicted: more sea ice than average in southern-most Arctic first week of August

Polar bear habitat update for the first week of August 2019 shows there is still more sea ice than average in Hudson Bay, the southern-most area of continuous habitation for this species. That certainly wasn’t part of the predictions of doom, especially since freeze-up in that region for the last two years has also been earlier-than-average which means a shorter ice-free season than we’ve seen for decades.

Despite ice coverage for the Arctic ice as a whole being marginally lower than it has been since 1979 for this time of year, sea ice for the first week of August was also above average around Svalbard in the Barents Sea and higher than the last few years in the Central Arctic, which is a critical summer refugium for polar bears that live in the peripheral seas of the Arctic Ocean, including the Chukchi (see photo below, taken in early August 2018).

Alaska waters with no sea ice are not a problem for Pacific walrus or polar bears

One of two alarming headlines that caught my eye this week was the ‘news’ on Monday that the waters off Alaska were now ice-free because of climate change, courtesy a story in the online media outlet Mashable that was later picked up by The Weather Channel and the UK mainstream paper The Independent. In addition, a large number of mainstream news outlets, including the New York Times and Newsweek, have reported that walruses came ashore this year at Point Lay, Alaska two weeks earlier than any year since 2007.

No one claimed this late July onshore movement of walruses was the beginning of the end of walruses but it was still blamed on human-caused climate change because it was associated with the  aforementioned ice loss in Alaska.

Neither event was truly ‘news’. Moreover, neither an ice-free Alaska in early August or walruses onshore two weeks earlier than 2017 will have any negative impact on local polar bear or walrus populations, whether due to human-caused climate change or natural variation. Well-fed polar bears everywhere are quite capable of going 4-5 months without food in the summer and a few thousand walruses at Point Lay will feed happily from this shore-based haulout for a few days to a few weeks as they have done many summers since 2007 before moving on to other Chukchi Sea beach locations – although the ‘leaving’ events never seem to get any media attention. Walruses will haul out on beaches in Alaska and Russia until the ice returns in October.

Sea ice adjacent to all major polar bear onshore summer refugia at 31 July 2019

For all the hand-wringing over sea ice extent this year and its supposed similarity to 2012, what is truly remarkable is that at the end of July ice remains adjacent to every single major terrestrial summer refugia known to be important for polar bears. Those refugia sites include (from west to east, starting in the Chukchi Sea): Wrangel Island, western Chukotka, Severnaya Zemlya, Franz Josef Land, East Greenland, virtually all the islands of the Canadian Arctic Archipelago (including Southampton Island in Foxe Basin and the southwest and eastern coasts of Baffin Island), and Western Hudson Bay.

Few bears spend the entire summer onshore along the Alaska coast: most still spend the summer on the sea ice and move with it as it contracts toward the Arctic Basin, as do many bears in the Barents, Kara, East Siberian, and Chukchi Seas. Until a few weeks ago, however, there was enough ice present that Beaufort Sea bears could go ashore if they wanted to do so. Continue reading

Polar bear spotted on Bear Island (Barents Sea) this winter for the first time in 8 years

A polar bear was spotted this year on Bear Island (Bjørnøya) in the southern Barents Sea on 8 March by the crew at the Meteorological Station. The last time these workers had seen a polar bear was 2011 but this year extensive Barents Sea ice literally brought a bear to their doorstep, similar to the way that sea ice brings bears to southern Labrador and Newfoundland in late winter and spring.

After below-average ice cover around Svalbard for most of the winter months of January and February, by early March the ice had expanded so far to the south it reached Bjørnøya. It was the kind of ice that hadn’t been seen in decades and almost immediately, a polar bear was spotted on shore. Given the length of time that the ice surrounding the island persisted, it is likely more bears came ashore but were not seen: the Meteorological Station at the north end of the island is the only place that people live over the winter (see maps below).

10 fallacies about Arctic sea ice & polar bear survival: teachers & parents take note

Summer sea ice loss is finally ramping up: first year is disappearing, as it has done every year since ice came to the Arctic millions of years ago. But critical misconceptions, fallacies, and disinformation abound regarding Arctic sea ice and polar bear survival. Ahead of Arctic Sea Ice Day (15 July), here are 10 fallacies that teachers and parents especially need to know about.

Polar bears are thriving despite global warming: this short essay explains why

This essay explains in simple terms why so many people still believe that polar bears are in peril when nothing could be further from the truth: it is an essential lesson that shatters the basis of the shameful indoctrination of young school children and undermines the baseless claims of activist protestors. It was written and translated into French for a special climate change feature issue (July) of the monthly French magazine Valeurs Actuelles (reviewed here) and reprinted by the French hunting magazine Chasses Internationales. It has also been translated into German for a dedicated climate change issue (11 July) of the Swiss weekly magazine Die Weltwoche.
