‘Alone’ and ‘Alone Frozen’ survivor reality show participants were never at risk of a polar bear attack

Spoiler Alert! Participants of the History Channel’s Season 9 ‘Alone’ and its spinoff, ‘Alone: Frozen’ reality shows were never at risk of a polar bear attack despite the marketing hype claiming they were, because coastal Labrador is only ‘polar bear territory’ when pack ice is present offshore, which it wasn’t when the shows were filmed. Shocking, I know!

I happened upon the trailer for the ‘Alone’ series while watching TV one night and the “set in the hunting territory of the mighty polar bear” claim caught my attention. So I watched a few episodes and did some followup. Before the series even ended, there were ads for the spinoff series, ‘Alone: Frozen’, which had even more polar bear hype. Here’s what I discovered–call it a Frivolous Friday post if you like, but I felt it had to be said.

Churchill problem polar bear reports for early 2022 have no mention of fat bears or excess sea ice

The first few reports on problem polar bear activity in Churchill are in, posted early this week (two together), starting the last week of July (25-31).

Funny how these reports in recent years (these included) don’t mention the condition of bears the way they used to as recently as 2017 (or the state of the sea ice). I guess it’s so they can’t be used as evidence against the prevailing mantra that western Hudson Bay polar bears that spend the summer onshore are starving because of the lack of ice due to human-caused global warming!

Polar bear shot after early morning attack on French tourist camping in Svalbard

There was another polar bear attack on Svalbard this morning, similar to others in previous years. As usual, the body condition of the bear was not mentioned (whether fat or thin) and photos of it were not published. The woman survived, the bear did not.

Hudson Bay sea ice update: many polar bears are still on low concentration ice offshore

Almost half of all tagged Western Hudson polar bears are still out on the ice of Hudson Bay, even though much of it is broken up in pieces: as of yesterday, 10 out of 22 bears were still offshore.

This is shaping up to be a great year for Hudson Bay bears!

It also appears none of the bears onshore are causing problems in Churchill, as the Polar Bear Alert Program weekly reports for Churchill have not yet begun. Last year the first report was issued for the first week of July, while in 2020 the first report didn’t come out until the end of August.

Most Hudson Bay polar bears are still offshore, excellent ice conditions for late July

With only a few days until the end of July, most Western Hudson Bay polar bears are still on a thick band of thick first year ice that remains close to shore. The few bears that have come off the ice appear to be nice and fat, indicating they had good spring feeding conditions.

We’ll have to wait a few more weeks to see if this year shapes up as it did in 2020, when the last of bears didn’t come ashore until the third week of August, despite there being very little visible ice. Last year, most of the bears were ashore by the end of July.

Expert admits polar bears in Svalbard are thriving despite the greatest loss of sea ice in the Arctic

In an article published last week, polar bear specialist Jon Aars is quoted as saying that Svalbard bears are “unexpectedly” thriving. However, he fails short of admitting that the bears don’t really need summer ice as long as they are well-fed in spring, which they have been for the last two decadesthis year included.

Aars said the sea ice in this area is declining more than twice as fast as anywhere else in the Arctic. But the polar bears here — unexpectedly — are thriving. [E. Haavik, Svalbard’s polar bears persist as sea ice melts — but not forever, 21 July 2022; my bold]

Spring 2018, Barents Sea

The suggestion by Aars that the Svalbard archipelago could one day be ice-free for the entire year is speculative hyperbole but even if that were to happen, it would only mean the permanent movement of 300 or so Svalbard bears to Franz Josef Land (still within the Barents Sea) where ice conditions are less volatile.

Thick sea ice in the Western Arctic is not good habitat for polar bears, seals, or walrus

A few weeks into the Arctic summer (July-September), sea ice in the Beaufort and Chukchi Seas is dominated by thick, multi-year ice.

At this time of year, multi-year ice is an important refuge habitat for many polar bears when seasonal ice melts out. However, it provides few opportunities for hunting seals. In fact, it is nearly as devoid of food as is the shore during the melt season. Consequently, most polar bears eat little over the summer whether they are on land or on sea ice due to the scarcity of seals.

Some of the first polar bears onshore in Western Hudson Bay are in excellent condition

From the live cams installed on beluga tour boats running near the Churchill River, we have some good photos of a few fat polar bears onshore in Western Hudson Bay.

These bears were attracted to the remnants of a beluga carcass with nothing much left on it (lower right in the photo) and stayed around for at least a few days. The female with her cub-of-the-year was remarkably tolerant of an adult male nearby.

Arctic sea ice still quite abundant for early summer

Despite rhetoric to the contrary, there is still plenty of sea ice over Arctic regions this summer, supplying feeding platforms for polar bears, ice-dependent seals, and walrus cows nursing their young calves. Forget about whether the numbers are below or above some short-term average, there is no catastrophe in the making for marine mammals in the Arctic at this time.

Remember, by early summer, young seals have left the surface of the ice and are in the water feeding; predator-savvy adults and subadults are hauled out on broken chunks of ice moulting their hair-coat. They may look like sitting ducks but polar bears have a hard time catching them because the seals are vigilant and have many escape routes available (due to all the open water). Most polar bears in Hudson Bay are still on the ice (you’ll see why below): the live cams near Churchill set up to watch polar bears are presently showing images of ravens with sea ice in the background, not bears.

This post is predominantly sea ice charts for mid-July, what we in the science field call observational evidence, aka ‘facts’. Keep in mind that satellites used to produce these images have an especially hard time distinguishing ice topped with melt water from open water, which means much more ice useful to these marine mammals is almost certainly present than is shown in the charts (as much as 20% more in some regions).

Arctic sea ice is constantly changing which means polar bears must be flexible in their requirements

In honour of upcoming ‘Arctic Sea Ice Day’ (15 July), I revisit my 2015 essay on sea ice stability and polar bears, called The Arctic Fallacy. It challenges the flawed and out-dated ecological concept that under natural conditions, sea ice provides a stable and predictable habitat for polar bears, walrus and seals. The wide-spread adoption of this fallacy has allowed the present-day doom and gloom attitude of most Arctic specialists to develop.

[Polar Bears International have declared July 15 to be ‘Arctic Sea Ice Day’ to further its propaganda efforts to ‘save our sea ice’, which they claim is disappearing at an alarming rate due to global warming.]
