Polar bear specialist calls Hudson Bay freeze-up ‘late’ yet bears were moving offshore 2 weeks ago

Predictably, polar bear specialist Andrew Derocher has finally posted a tracking map of the Western Hudson Bay bears his team has fitted with collars and eartags–two weeks after bears were released from Churchill’s polar bear jail, which is the local signal that there is enough sea ice for bears to leave shore. As I reported two weeks ago, release of jailed bears happened this year on 10 November. And as I predicted in that post, by waiting so long after that event to post his map, Derocher can make it seem to his naive followers on Twitter that the bears are just starting to leave now (the last map he posted was on 11 November, when none of his bears had moved). He reinforces this by calling WH freeze-up “late”, when by all objective measures (including local informants reporting bears on the ice) it was as early as it had been in the 1980s (Castro de la Guardia et al. 2017).

Recall that fall is the second-most important feeding season for polar bears, due to the fact that seals are strongly attracted to newly-forming sea ice. It’s their chance to regain some or all of the weight lost over the summer, before the long winter fast begins (while bears indeed hunt when they can, they are not often successful during the depths of the Arctic winter: most bears are at their lowest weight by March).

Dispelling the doomsday propaganda in DisneyNature’s new polar bear ‘documentary’

In a move that echoes the collaboration of activist organization World Wildlife Fund (WWF) with Netflix that brought us Sir David Attenborough’s walrus deception in ‘Our Planet’ that I chronicled in my latest book, ‘Fallen Icon’, streaming service DisneyNature has joined with activist organization Polar Bears International (PBI) to create a polar bear ‘documentary’ (called ‘Polar Bear’) that we can tell is propaganda because they’ve chosen to release the “cute and worrying” film on Earth Day (Friday 22 April 2022). In fact, the two films have a producer in common: Alastair Fothergill.

In the case of ‘Our Planet’, WWF bankrolled the film series for Netflix to ensure the content they desired; in ‘Polar Bear’, the tables are turned: DisneyNature is paying PBI for their assistance getting the polar bear film shots and providing their biased content, via money they are calling a research grant. I think you know by now what to expect. However, here are the facts about polar bear conditions in Svalbard, where the film was shot, and some good news from Western Hudson Bay this year, courtesy of Mike Reimer and his team at Churchill Wild. In short, there is still no climate emergency for polar bears: the hype is based on old models that failed spectacularly and new ones which depend on old data and totally improbable climate scenarios (Crockford 2017, 2019; Hausfather and Peters 2020; Molnar et al. 2020).

10 fallacies about Arctic sea ice & polar bear survival refute misleading ‘facts’

This updated blog post of mine from last year is as pertinent now as it was then: it’s a fully-referenced rebuttal to the misleading ‘facts’ so often presented this time of year to support the notion that polar bears are being harmed due to lack of summer sea ice. Polar Bears International developed ‘Arctic Sea Ice Day’ (15 July) to promote their skewed interpretation of polar bear science at the height of the Arctic melt season. This year I’ve add a ‘Polar Bears and the Arctic Food Chain‘ graphic, which readers are free to download and share. For further information, see “The Polar Bear Catastrophe That Never Happened“.

10 fallacies about Arctic sea ice & polar bear survival: teachers & parents take note

Summer sea ice loss is finally ramping up: first year is disappearing, as it has done every year since ice came to the Arctic millions of years ago. But critical misconceptions, fallacies, and disinformation abound regarding Arctic sea ice and polar bear survival. Ahead of Arctic Sea Ice Day (15 July), here are 10 fallacies that teachers and parents especially need to know about.

Sea ice silly season: Wadhams spouts fake facts about polar bears of northern Greenland

As the seasonal minimum for Arctic sea ice approaches, the media get carried away by hyperbole. Tha’t been true since 2007. This year, other outlets will need to work hard to beat yesterday’s bit of nonsense from The Independent trying to out-do The Guardian: it not only includes false polar bear facts (from sea ice researcher Peter Wadhams) but leads with last year’s controversial SeaLegacy video of an emaciated polar bear. Sea ice silly season has truly begun.

East Greenland Scorsby Sound March 2011 on Kap Tobin_Rune Dietz_press photo

Wadhams (described as “one of the UK’s leading sea ice scientists” although not a particularly respected one) was interviewed about the small area of open water that opened up over the last few days in northern Greenland (see NSIDC photo below), driven by offshore winds (not melt). This region is the eastern-most part of the area that is considered the “last holdout” for Arctic sea ice: an immense band of very thick (4-20m) multiyear ice that stretches across the Arctic Ocean shores of the Canadian Arctic Archipelago.

The open water is expected to last a few days at most but Wadhams was absolutely breathless with dire warnings of what this might mean for the future of polar bear in the region (about which he knows nothing), rhetoric ramped up even further by the news outlet with quotes from co-director of the Grantham Institute (London), Martin Siegert, and predictions on how low the sea ice minimum might be.

US biologist’s defense of flawed polar bear predictions is an embarrassment to science

A few days ago in a radio interview, a senior US Fish & Wildlife biologist repeated the tall tale that Southern Beaufort Sea polar bear numbers declined in recent years due to loss of summer sea ice. But restating this egregious misinformation does not make it true.

polarbears-arcticnatlwildliferefuge-suzannemiller-usfws_labeled_sm

The Southern Beaufort population did decline between 2001 and 2006 but it was due to natural causes (thick ice in spring from 2004 to 2006) – it had nothing to do with recent summer sea ice loss and Eric Regehr knows it.

There is no evidence that the population decline continued after 2006, so it cannot be said to be still declining. Moreover, the situation in the Southern Beaufort does not support the predictions made by Regehr and his colleagues that polar bear populations will decline precipitously if summer sea ice declines further.

My recently published paper demolishes the message of doom for polar bears and the misinformation it’s based upon: it’s free and written in straight-forward scientific language.

Crockford, S.J. 2017. Testing the hypothesis that routine sea ice coverage of 3-5 mkm2 results in a greater than 30% decline in population size of polar bears (Ursus maritimus).

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

W. Hudson Bay had 1030 polar bears at last count and that is the official number

The IUCN Polar Bear Specialist Group, the IUCN Red List, and Environment Canada (see below) agree that the population size of Western Hudson Bay subpopulation is 1030 or about 1000 bears, based on surveys conducted in 2011.

western-hudson-bay-surveys-2011-compared_polarbearscience-16-dec-2016

For the last few months (most recently, here and here), Andrew Derocher has been telling anyone who will listen that that the number is 800. And no one challenges him – not a single reporter asks where the number comes from, not a single research colleague who knows the truth has publicly stated that Derocher is spreading misinformation.

UPDATE 16 December 2016, half an hour after posting: Add The Atlantic to those accepting Derocher’s misinformation on WHB polar bear numbers without question, and failing to see that because patrols in Churchill were stepped up considerably after a serious mauling occurred in 2013 (because several bears got through their Halloween dragnet), more “problem” bears in Churchill since then only mean the Polar Bear Alert folks are doing their jobs.

But what does The Atlantic conclude, after talking to Derocher?

The Churchill bears…are probably doomed.

Never was a rational book on the science and conservation status of polar bears more desperately needed – it will be available soon.

Columnist admits video on polar bears and global warming contained a serious error

Since mid-August,  Vancouver Sun columnist Daphne Bramham has been filing a series of articles from an expedition cruise through the Northwest Passage for a feature called “Above the Arctic Circle”. One of these appeared on August 18, along with a video called “What to know about polar bears and global warming” and it contained an egregious error that should have stood out to any educated person as being wrong by several orders of magnitude:
