Posted onMarch 15, 2023|Comments Off on Birthing season for harp seals in Labrador Sea just in time to feed hungry polar bears
The main birthing period for NW Atlantic harp seals has arrived. Local populations of ringed and bearded seal pups will soon follow but in the Gulf of St. Lawrence in eastern Canada, the pupping season for harp seals that is usually in progress by this time has likely been redirected north due to lack of suitable ice conditions. Sea ice off Labrador and Newfoundland is in good condition and this is where the vast majority of the global population go to give birth (ca. 7.6 million vs. 1.5 million in the White Sea and 434,000 in east Greenland).

A small pod of white-beaked dolphins entrapped on Friday (10 March) by a sudden surge of ice along the northern Newfoundland coast were lucky to have been rescued by humans before polar bears could get to them. We know the bears are around, drawn south by the millions of harp seals giving birth to their pups in the area. In April 2014, something similar happened to white-beaked dolphins in Svalbard and they became a welcome meal for at least six polar bears (Aars et al. 2015).
UPDATE 20 March 2023: Another pod of white-beaked dolphins has perished from the ice over the weekend. More than 30 dolphins were trapped near the town of Carbonear, which is on Conception Bay (the next big bay southeast from Trinity Bay), according to CBC News. Given the ice conditions, this is almost certainly a different pod to the one reported on two weeks ago.

“It’s been happening here forever,” he said, adding it’s not just a problem for dolphins. “It kills blue whale and humpback whales and whatever gets into it.”

Conservation officials issued an alert to residents of coastal communities to be aware of polar bears coming ashore over the last week in northern Newfoundland and southern Labrador, after a woman photographed a bear outside her home on Tuesday morning (7 March 2023). Since no bears in this subpopulation are tracked with satellite radio collars, we have no idea if there are a few dozen bears — or a few hundred of them — hunting on the ice and available to come ashore when the opportunity arises.

The Polar Wildlife Report is a peer reviewed summary of the most recent information on polar animals, relative to historical records, based on a review of 2022 scientific literature and media reports. It is intended for a wide audience, including scientists, teachers, students, decision-makers and the general public interested in animals that live in Arctic and Antarctic habitats, including polar bears, killer whales, krill, and penguins.
Posted onFebruary 23, 2023|Comments Off on Published field study observations – not population size – prove polar bears are thriving
There is irrefutable evidence from Barents and Chukchi Sea subpopulations, among others, that polar bears are fat and reproducing well despite marked declines in summer sea ice over the last two decades. These indicators of physical and reproductive health, in any species, are signs of thriving populations. However, these facts negate the premise that polar bears require abundant summer sea ice to flourish, and that creates a problem for polar bear specialists who continue to make that claim (Amstrup et al. 2007; Crockford 2017, 2019).

In other words, the assessment that polar bears are currently thriving is not based solely on estimates of a slight increase in global population size but on published data gathered from field studies on the bears’ physical and reproductive health.
Oddly, biologists repeatedly turn to data from Western Hudson Bay to drive home to the public their preferred message that polar bear health and abundance are being negatively affected by recent summer sea ice declines. However, they fail to mention that robust field data from many other regions, including the Barents and Chukchi Seas, support the opposite conclusion. Moreover, wherever possible, they mumble under their breath (or leave out entirely) the fact that poor ice conditions could not be blamed for a 27% decline in polar bear numbers in Western Hudson Bay since 2016 — because their own data showed sea ice conditions had been strong!

There’s abundant sea ice in the Bering, Greenland and Labrador Seas, although less than usual in the Barents Sea because strong winds drove the ice north. Any time there is a bit less sea ice than usual the catastrophists begin caterwauling but this time the rhetoric is a little different.
Relying on the data I referenced used to be uncontroversial. When a CNN science journalist did an investigation similar to AFP’s in 2008, he spoke to numerous scientists and they agreed “that polar bear populations have, in all likelihood, increased in the past several decades.” When polar bears in 2008 were listed as a threatened species under the Endangered Species Act, the decision noted that the population “has grown from a low of about 12,000 in the late 1960’s to a current worldwide estimate of 20,000-25,000.” The data here haven’t changed, only the media’s willingness to disregard annoying facts.
The result is that the public is denied access to accurate data and open debate about these very important topics. Ridiculous points on one side are left standing while so-called fact-checking censors inconvenient truths. If we’re to make good climate policy, voters need a full picture of the facts.

I would add this fact: in 1982, polar bears were listed by the IUCN as ‘vulnerable’ but by 1996, that had changed to ‘lower risk/conservation dependent’–now called ‘least concern‘ (see screencap below) because population numbers had rebounded after more than 20 years of international protection from over-hunting. The reversion to ‘vulnerable’ in 2006 was based entirely on predictions that population numbers would decline in the future due to see ice loss, which so far has not happened (Crockford 2017, 2019; Crockford and Geist 2018).

Posted onJanuary 18, 2023|Comments Off on Two dead in fatal polar bear attack in Alaskan village of Wales on the Bering Strait
Two people tragically died yesterday afternoon after an attack by a polar bear in the village of Wales on the Bering Strait. Few details are available and bad weather apparently hampered officials getting to the village immediately.
As expected, virtually all news reports are implying that a generic ‘lack of sea ice’ can be blamed for the incident. As usual, the specifics of this case show this claim is not only nonsense, but dangerous.
With the loss of sea ice and the ocean staying open later in the year, polar bears have been spending more time on land, which increases the chance of human encounters, said Joseph Jessup McDermott.
Polar bear attacks in winter are almost always associated with a bear that has not been able to resume feeding in the fall. More bears and restricted hunting means more young bears (as well as old bears or sick ones) become food stressed because they can’t compete with big mature males for food. Mature bears often steal any seals that young bears are able to kill, making the youngsters desperate for food.
The Chukchi Sea polar bears are currently thriving and numbers may still be increasing (AC SWG 2018; Conn et al. 2021; Regehr et al. 2018; Rode et al. 2014, 2015, 2018).
More details to follow on this horrific incident as they become available.
UPDATE 18 January 2023, 5:30PM PT: According to an Associated Press account, the victims were a 24 year old woman and her one-year old son: “Summer Myomick of Saint Michael and her son, Clyde Ongtowasruk, were killed in the attack, Alaska State Troopers said in a statement.”
No more details were provided on the state of the bear involved (sex, age, body condition). Regarding the blame-game, even though recent studies have shown that ringed and bearded seals in the Chukchi Sea are doing very well (Adam et al. 2019; Crawford and Quakenbush 2013; Crawford et al. 2015), Geoff York from Polar Bears International suggests there may not be enough seals for polar bears or the something may be wrong with the sea ice:
In this case, even though there is ice in the Chukchi and northern Bering seas, the quality of that ice is not known that well. More importantly, York said they don’t know what’s going on under the ice — or what the availability of seals and other prey is for polar bears.
The changes are also happening in winter, when people assume they are safe from polar bears being on shore.

On the first anniversary of Fallen Icon, I wonder if Sir David has made his last backroom deal? His years of relentless messaging anti-capitalistclimate doom seemed like a concerted plan to build a legacy based on something other than smooth talking: I am convinced Attenborough saw the shocking film footage of walrus falling to their deaths presented in the Netflix/WWF extravaganza Our Planet as the leverage he needed to kick-start an aggressive campaign to promote action on climate change and curb capitalism. But it all collapsed at COP26 in 2021 with his failure to make any difference at all.
