Tracking polar bears in the Beaufort Sea May and June updates

At the end of June, there were nine bears remaining from the original 14 that were tagged with glue-on ear transmittors in April 2018 near Kaktovik, Alaska by US Geological Survey biologists.

Original caption: “Movements of 9 satellite-tagged polar bears for the month of June, 2018. These bears received satellite eartag transmitters in 2018 on the spring-time sea ice of the southern Beaufort Sea. Polar bear satellite telemetry data are shown with AMSR2 remotely-sensed ice coverage for 30 June, 2018.”

As ear tags are notoriously short-lived, there may not be any remaining by the end of July but if there are, I will post the tracks. The map for May 2018 is below.

As polar bear populations fail to decline with sea ice, message of doom intensifies

If 10 years of summer sea ice levels expected to kill 2/3 of the world’s polar bears by 2050 hasn’t had an impact, why would anyone expect a bit less summer ice will do the job?

sea-ice-prediction-vs-reality-2012_polarbearscience

The more the polar bears fail to die in droves, the shriller the message from activist polar bear researchers – via willing media megaphones – that the great death of the bears will soon be upon us, just you wait and see!

Some big media guns were out this past week spreading the prophesy of doom fed to them by the polar bear researchers most committed to the “threatened with extinction” narrative: The New York Times, The Atlantic, The Guardian. The desperation is becoming palpable as the public catches on to their epic failure.

In 2007, the sea ice dropped to a level the experts said wouldn’t be reached until mid-century, and since then, it has remained at that low level (about 3-5mkm2, give or take some measuring error). And in 2007, US Geological Survey (USGS) biologists said with absolute confidence that when sea ice levels reached that point, 2/3 of the world’s polar bears would be gone.

No bears at all would remain, they said, in Western Hudson Bay (the Churchill bears), Southern Hudson Bay, Foxe Basin, Davis Strait, Baffin Bay, Southern Beaufort, Chukchi Sea, Barents Sea, Kara Sea, and the Laptev Sea:  ten out of 19 subpopulations would be extirpated if sea ice levels in most years dropped to the summer lows in the 3-5 mkm2 range.

On the basis of that prediction, polar bears were declared ‘threatened’ with extinction by the US Fish & Wildlife Service (USFWS) under the Endangered Species Act (ESA).

But nothing of the kind happened. There are still lots of polar bears – and not even struggling-to-survive bears but lots of fat healthy bears everywhere across the Arctic, in what were considered by USGS biologists to be the most vulnerable regions of all: Western Hudson Bay (i.e., Churchill), Chukchi Sea and Southern Beaufort (Alaska) and the Barents Sea (Norway).

This is the truth the world needs to hear: the experts were wrong. Polar bears have not been driven to the brink of extinction by climate change, they are thriving. This is the message of each of my two new books (one of which is appropriate for kids of all ages, see the sidebar).

In turns out that polar bears are much more resilient to changing levels of sea ice than data collectors assume and the proof is in the current healthy populations everywhere. Continue reading

Kaktovik, AK has a polar bear problem but not because bears are desperate for food

PBS has published a bizarre poor-starving-polar-bears story that uses pictures of fat, healthy bears to illustrate the supposed desperation of malnourished bears of the Southern Beaufort Sea that is blamed on declining sea ice.

pbs-newshour-headline_15-october-2016

The photo of the fat bear above, taken by the Kaktovik resident quoted in the 15 October 2016 PBS story, Polar bears, growing desperate for food, threaten native Alaskans, accompanies this statement:

“While images of malnourished polar bears have become a national symbol of the effects of climate change, they are a front line reality for Native Alaskans, who face them on their own property and do not want them to get hurt.”

Except this is not a story about starving bears but too many fat bears hanging around one particular community looking for other kinds of food – after being lured in by the enticing smell of rotting whale meat left onshore by the residents.

If photos of starving Beaufort bears existed that PBS could have used to illustrate this story, I’m certain those photos would have been used. But virtually all of the pictures I’ve seen of Kaktovik bears are the epitome of health – fat and sassy – but none that could be described as starving.

It turns out that while native Kaktovik residents have profited from tourists and journalist who have shown up in droves to view the large numbers of bears attracted to the bone piles left after butchering summer-caught bowhead whales, the bears have also put the community at risk of personal attack and loss of stored food. Who would have thought?

Residents of Kaktovik (see map below) have unwittingly enticed these polar bears ashore and now must deal with the consequences. As the residents of Churchill discovered decades ago, having polar bears close to your community comes with benefits, problems – and danger.

There is no doubt that Kaktovik has a polar bear problem but it cannot plausibly be blamed on anthropogenic global warming, retreating sea ice, or starving bears – an irresistible attractant close to the community is the cause and solutions must be found to keep residents safe and their food secure. The PBS article discusses a few of those solutions. Some quotes and background below.

Tracking Western Alaskan polar bears in the Beaufort in Sept – all 3 chose Canada

All three polar bear females tagged in the Southern Beaufort Sea far west of Kaktovik (near Barrow) spent all or most of September onshore in the Northern Beaufort area of Canada.

Beaufort polar bear with tight collar found and rescued says U of Alberta

It appears that the male polar bear with a too-tight satellite radio collar that was photographed late last year near Kaktovik on the North Slope of Alaska has been captured and his faulty collar removed, says a statement posted on the University of Alberta website 25 August 2016. The animal was reported to be healthy and behaving normally.

polar-bear-radio-collar_CBC Oct 28 2015

As far as I can tell, no press release was issued and no media interviews have been conducted despite the strong interest in the fate of this bear last fall (previous reports here, here, and here) – I found the notice by accident while looking for something else.

Andrew Derocher and his research team from U of A have admitted they collared this bear and the Polar Bear Facts webpage where this recent statement appears was developed to deal with the many inquiries about the status of this bear (dubbed “Andy” by some).

Note the statement, copied below, does not confirm that this is indeed the same bear as was photographed last year – they just assume it is. No photo is provided of the rescued bear, although clearly some were taken. However, if it is not the same bear, then another subadult male spent the winter of 2015-2016 on the ice of the Beaufort Sea with a tight and non-functioning collar that was not about to fall off by itself.

New paper shows no harm from more time on land for S. Beaufort polar bears

polarbears-arcticnatlwildliferefuge-suzannemiller-usfws_labeled_smTake-home quote from a new polar bear paper by Todd Atwood and colleagues (2016):

“…there is no causal link between the patterns in polar bear vital rates and increased use of terrestrial habitat…”

In other words, there was no information to link the increased time polar bears spent onshore with either an increase or a decrease in body condition, survival or cub production. The authors did find that polar bears were strongly attracted to the bone piles that accumulated in the fall from 2010-2013 after Inuit bowhead whale (Balaena mysticetus) hunting at Barrow, Cross Island, and Kaktovik. Isn’t that a surprise?

The results also appear to confirm previous work that showed terrestrial (land-based) foods are not important to polar bears – a conclusion I totally agree with and which I discussed last year here. No wonder there was no press release issued by USGS about this study. It’s only “news” because someone the Anchorage Daily News interviewed lead-author Atwood yesterday as a way of promoting the International Bear Conference (see previous post here, now updated with a link to the Talk of Alaska radio podcast). Atwood implied there could be advantages to bears from feeding on the bone piles but admitted he had no data to support that assumption.

Russian polar bear scientist critical of using radio collars

In an update to an earlier story from last month about a male polar bear spotted near Kaktovik with a tight satellite radio collar, a Russian biologist has voiced some some serious criticisms of the use of these devises.

polar-bear-radio-collar_CBC Oct 28 2015

In another news outlet, Andrew Derocher has finally admitted publicly that the Kaktovik bear with the tight collar is a male and is”likely his” (Global News, 23 November 2015; “Is this polar bear really being choked by a research collar?”). The male bear appears to have been fitted with a collar some time between 2007 and 2011. The collar should have fallen off by now but hasn’t. Derocher suggested maybe the collar isn’t really too tight and the blood might not belong to the bear. And that if the bear really wanted the collar off, he “…will be able to remove it himself.”

The criticisms of the use of collars are well worth reading.

UPDATE 25 November 2015: Another CBC report, not much more useful information except confirmation this is a male bear.
