Attenborough twisted the truth about dying walrus: why believe him on climate change?

Sir David Attenborough hid the truth about hundreds of walrus falling off Siberian cliffs to their deaths a few years ago – he insisted this was due to climate change, but we now know he was well aware the tusked beasts fell because they were being stalked by predatory polar bears. Since he was willing to tell outright falsehoods about dying walrus to powerful elites at the 2019 World Economic Forum, I expect he’d say anything to advance his agenda with members of the UN Security Council.

Headline quotes from Attenborough’s address to the UN Security Council today:

“Climate change a threat to global security

Climate change could, within a lifetime, destroy “entire cities and societies

“Climate change is biggest threat modern humans have ever faced”

In other words, lots of emotional hyperbole from a showman who wants to leave a legacy. This is not the dispassionate science we require to make sensible decisions about the future. Attenborough spouted contrived nonsense about walrus and now spouts contrived nonsense about climate change.

Fact: polar bears are thriving despite sea ice loss according to the scientific literature

Is Facebook now an expert on polar bear conservation status? Apparently they have decreed themselves the last word for online content. There is a plan afoot to label anything that says polar bears are not being harmed by recent sea ice declines as ‘disinformation’ – but on whose authority? Thanks to Josh for the cartoon below.

A new section of the Climate Science Information Center, launching alongside the labelling trial, debunks common myths such as the false claim that polar bear populations are not suffering due to global heating, or the widespread belief that excess carbon emissions help plant life. Facebook is working with climate communication experts from around the world, including at the University of Cambridge, to produce the content.

Ah, they’re consulting ‘climate communication experts‘! Those experts surely must be up on all the latest papers and not trusting the word of obviously biased conservations organizations like the WWF or PBI whose real reason for existence is the generation of as much money in donations as possible?

The peer reviewed literature supports the claim that polar bears are currently thriving despite recent ice declines – especially in the Chukchi and Barents Seas – regardless of what computer model predictions say about what might happen in the future. This is a fact, not a ‘myth’. See my paper from 2017 and my 2019 book for most of the citations (Crockford 2017, 2019) and others in the reference list below. Check them out yourself before you believe Facebook. Ask me for any paper you’d like to see via the ‘contact me’ form and I’ll send it along.

Attenborough’s cliff-dying walrus convinced elite Davos influencers of a global climate emergency

For the past two years, the Netflix/Attenborough ruse to blame climate change for walruses falling from a high cliff to their deaths seemed like a silly PR stunt. But it appears the film’s real purpose was to convince a far more important audience than paying Netflix customers that a global ‘climate emergency’ was going on: the elite influencers and world leaders who attended the World Economic Forum in Davos in January 2019, where the dying walrus film clip was introduced and interpreted to the audience by Sir David Attenborough himself.

Top six polar bear stories of 2020

Here are the six most important polar bear stories I wrote about in 2020 that are worth reading if you missed them.


These posts cover new evidence that polar bears are thriving (including more populations stable or increasing) despite recent declines in summer sea ice blamed on climate change, an explanation of why the simplistic ‘less ice, fewer bears’ is false and a short post that shows a much-publicized new model predicting future extinction of polar bears is scientifically implausible. Honourable mention goes to a story refuting the claim that Alaskan polar bear cubs are at risk from oil exploration in coastal Wildlife Refuge.

New footage reveals Netflix faked walrus climate deaths

Netflix faked ‘Our Planet’ walrus deaths in order to blame them on climate change – polar bears actually were the cause of walrus falling to their deaths from a Siberian cliff, independent video evidence from Russia shows.

Polar bear research on hold in Western Hudson Bay due to COVID-19 restrictions

After spring polar bear research was cancelled in Western Hudson Bay (and pretty much everywhere else) this year because of Covid 19 concerns, it now transpires that fall research is out as well. Travel restrictions implemented by government departments and university administrations (not the health department) apparently mean fall programs to assess the health and status of polar bears in Western Hudson Bay have been put on hold.

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.

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.

Don’t let the ‘trust my word, I’m an expert’ hyperbolic testimony from activist scientists like Steven Amstrup and others hold sway on this issue – see for example Alaska polar bear den disturbances part of ‘death by a thousand cuts,’ researcher says (biologist Wesley Larson on Alaska Public Radio, 14 July 2020), or activist conservation organizations Polar Bears International and World Wildlife Fund. Have a look at the facts on the matter taken from the published literature, which I summarize below (as many pdfs provided as possible).

Emperor penguin numbers rise as biologists petition for IUCN Red List upgrade

Emperor penguin (Aptenodytes fosteri) populations in 2019 were found to have grown by up to 10% since 2009 – to as many as 282,150 breeding pairs (up from about 256,500) out of a total population of over 600,000 birds (Fretwell et al. 2012; Fretwell and Trathan 2020; Trathan et al. 2020) – despite a loss of thousands of chicks in 2016 when an ice shelf collapsed. Yet, biologists studying this species are currently petitioning the IUCN to upgrade emperor penguins to ‘Vulnerable’ (Trathan et al. 2020), based on models that use the implausible and extreme RCP8.5 ‘worse case climate change scenario (e.g. Hausfather and Peters 2020) that polar bear biologists find so compelling. Not surprisingly, their unscientific models suggest emperor penguins could be close to extinction by 2100 under these unlikely conditions – but if we reduce CO2 emissions via political policy, the penguins will be saved!

Surprisingly, these researchers are going ahead with their petition to have emperor penguins uplisted despite the population increase and the reservations their colleagues expressed in 2018 about using climate change predictions to arrive at a classification of ‘Near Threatened’ for the IUCN Red List assessment (Birdlife International 2018), as noted below in their ‘justification’:

This species is listed as Near Threatened because it is projected to undergo a moderately rapid population decline over the next three generations owing to the projected effects of climate change. However, it should be noted that there is considerable uncertainty over future climatic changes and how these will impact the species.

Like polar bear biologists, some emperor penguin biologists just won’t give up on the prediction they developed back in the mid-2000s that climate change is sure to drive this species to near extinction. For example, Jenouvrier et al. (2009) calculated that there was at least a 36% chance of a 95% or more decline in emperor penguins by 2100 (what they called a “quasi-extinction”) due to changes in sea ice distribution. They suggested a decline of this magnitude would entail a fall from about 6,000 breeding pairs to about 400 in a single colony.  The newest model (Jenouvrier et al. 2020) similarly uses the RCP8.5 ‘worse case’ scenario to predict near-extinction by 2100, as their ‘graphic abstract’ below shows.

Jenouvrier et al 2020 emperor penguin pop decline graphic abstract

This group are also recommending that “the species is listed by the Antarctic Treaty as an Antarctic Specially Protected Species” that would require a Species Action Plan (Trathan et al. 2020). And as co-author Peter Fretwell told the BBC last fall (9 October 2019):

“Everything we know – all the experts, all the models – tells us that Emperors are going to be in real trouble. We need to pull out all the stops to help them. That’s going to be hard because we know the one thing that’s really going to save them is stabilisation of the global climate.”

Sounds like something a polar bear specialist would say. Except that for polar bears, the catastrophe they keep predicting just won’t happen despite the fact that summer Arctic sea ice has been declining faster than anyone expected – so far, an almost 50% decline in ice has already happened yet global polar bear numbers keep slowly increasing (Crockford 2019; 2020).

I’d suggest that using far-fetched ‘worse case’ scenario predictions to propose an unlikely but scary-sounding future catastrophe isn’t likely to work any better for emperor penguins than it has done for polar bears, especially when the animals keep thriving.

However, some of the papers listed below are open access, so if you’re interested in more details I suggest you have a look. If you’d like a copy of the modelling paper (Jenouvrier et al. 2020), contact me and I’ll send it along. You’ll find more on the emperor penguin conservation issue in this essay by biologist Jim Steele.

Six good years in a row for the polar bear subpopulation used to predict species demise

In something resembling a new pattern for Western Hudson Bay polar bears, most of the animals are still out on the ice in late July this year, just like they were in the 1980s. The same thing happened last year but was brushed off as a happy anomaly. However, after last fall’s 1980s-like early freeze-up, this makes the sixth year in a row of good to very good sea ice conditions for Western Hudson Bay polar bears. No wonder polar bear experts haven’t published these data: good sea ice conditions along with polar bears coming ashore fat and healthy are not just inconvenient – they threaten to destroy the extinction panic narrative that depends on Western Hudson Bay bears showing evidence of harm from reduced sea ice.
