Posted onSeptember 20, 2020|Comments Off on Potential impact of the second-lowest sea ice minimum since 1979 on polar bear survival
The annual summer sea ice minimum in the Arctic has been reached and while the precise extent has not yet been officially determined, it’s clear this will be the ‘second lowest’ minimum (after 2012) since 1979. However, as there is no evidence that polar bears were harmed by the 2012 ‘lowest’ summer sea ice this year’s ‘second-lowest’ is unlikely to have any negative effect.
In this summary of how polar bears have been doing since the the lowest sea ice minimum in 2012, I show that contrary to all predictions, polar bears have been thriving despite reduced summer ice in the Barents, Chukchi and Southern Beaufort Seas, and because of unexpectedly short ice-free seasons in Hudson Bay and less multiyear ice in the Canadian Arctic Archipelago.
UPDATE 21 September (10:20 PT): NSIDC has just announced the Arctic sea ice extent minimum (preliminary) for 2020 at 3.74 mkm2 reached on 15 September. See full report here.
Also, note that a mother with a litter of triplets spotted along the coast of Wapusk National Park (just east and south of Churchill) in good condition, 15 September 2020 (see photo below). Biologist Nick Lunn falsely claimed in 2018 that no triplet litters had been born in Western Hudson Bay since 1996 – a correction made later claimed Lunn meant there hasn’t been any triplet litters seen in the fall, which was also not true in 2017 or in 2020:

A 2 year old male polar bear died yesterday (10 September 2020) during the sedation procedure used by Svalbard researchers. Although most polar bear research is on hold this year due to Covid-19, apparently the annual fall research in Svalbard conducted by Norwegian biologists has been able to continue.
Posted onSeptember 6, 2020|Comments Off on Sceptical covid-19 research and sceptical polar bear science: is there a difference?
This essay about medical researchers having trouble getting their papers published because the results don’t support the official pandemic narrative has disturbing parallels with my experience trying to inject some balance into the official polar bear conservation narrative.1 Especially poignant is the mention of models built on assumptions sold as ‘facts’ that fail once data (i.e. evidence) become available – which of course is the entire point of my latest book, The Polar Bear Catastrophe That Never Happened.

The guards from a cruise ship who shot an emaciated bear in self-defense in late July 2018 on the remote island of Phippsøya in northern Svalbard have had criminal charges against them dropped. It is illegal to kill polar bears in Norway, so the death of the bear automatically triggered a criminal investigation.
This case, which made international headlines and sparked outrage at the time, also saw charges laid against the cruise ship that employed the guards. However, all charges against the company have also been dropped. See below for details on the decision and my post about the incident in 2018. No information on the condition of the bear was included in the statement about criminal charges.
Posted onSeptember 1, 2020|Comments Off on First polar bear alert report for Churchill an astonishing seven weeks later than last year
The first report of the Polar Bear Alert Program in Churchill, Manitoba was released today(1 September), a full seven weeks later than last year due to many bears remaining on the Western Hudson Bay ice much later than they have done in the past.
As I mentioned previously, as long as I’ve been collecting these published reports (2015), there has not been a first report of the season issued later than the second week in July, so this year is really unusual and I suspect similar to the 1980s.
I thought it possible that this was a Covid-related delay getting conservation officers to Churchill but as you’ll see above, that appears not to be the case: there simply have been not enough serious problems with bears in Churchill to warrant sending officers out before last week. No information on the general condition of bears was included this year, as it has been in other years (see below). Activity this last week in August 2020 was similar to the first week in July 2018.
Posted onAugust 28, 2020|Comments Off on Fatal polar bear attack in Svalbard unfairly blamed on lack of sea ice
A fatal polar bear attack in Svalbard, in the early hours of 28 August 2020 just outside the main town of Longyearbyen, is being unreasonably blamed on lack of sea ice. Details of the attack show it was made by a three year old male: such subadult bears are historically responsible for most attacks on people and they are known to be especially dangerous. It looks to me like someone should have seen this tragedy coming and stepped in to prevent it.
I will update this story as more information comes in but see below for the details known so far.
Posted onAugust 27, 2020|Comments Off on Amid crying over low Arctic ice, W Hudson Bay polar bears leave ice as late as 2009
This year, the last collared Western Hudson Bay polar bear to leave the ice left as late, or later, than the last collared bear did in 2009 (which was an unusually late breakup year) and so far, all bears spotted have been in good physical condition despite inhabiting one of the most southern regions of the Arctic. All the while, sea ice experts have been hand-wringing about low Arctic sea ice –– in general and as polar bear habitat.

Posted onAugust 18, 2020|Comments Off on Risk to Alaskan polar bear cubs from oil exploration in coastal Wildlife Refuge is small
A bill recently introduced to US Congress (30 July 2020) is supposedly meant to “safeguard the Beaufort Sea polar bear’s denning habitat”. However, the bill is named the “Polar Bear Cub Survival Act”, which tells us this is an appeal to emotions rather than a call for rational decision-making. In fact, few Southern Beaufort Sea polar bear cubs are born on land in the Alaska National Wildlife Refuge and the risks to them from oil exploration is not overwhelming.
Despite a modest decline in summer sea ice since 1979, only about half of Southern Beaufort Sea polar bear females currently make their dens on the sea ice in late fall. Recent research confirms results from older studies that show denning females in Alaska are highly tolerant of the kind of disturbance associated with oil exploration and few dens are found more than about 1 km from the shore. This emotion-laden bill is not really about protecting polar bears: it’s a political move aimed at preventing oil exploration along the coast of Alaska after previous efforts failed. It comes ahead of an announcement today (18 August 2020) that the White House will begin to auction off leases for oil drilling in the ANWR.
Posted onAugust 15, 2020|Comments Off on Few bears on the ice off Western Hudson Bay at 14 August but will be onshore soon
Polar bear biologist Andrew Derocher published a tracking map of his collared polar bear females that shows one bear (out of 11) still on the rapidly diminishing ice north of Churchill in Western Hudson Bay – and where there is a collared female, there is almost certainly other bears doing the exact same thing:
Without evidence to support such a claim, Derocher (below) assumes this collared female is probably hunting seals. In fact, last year he admitted that most bears on Hudson Bay from at least July onward are unlikely to be successfully hunting seals:
