In contrast to 2016, when freeze-up along Western Hudson Bay was about as late as its ever been (early December), ice is already forming along the shore of northern Hudson Bay. There is much more ice than usual for this date, indicated by the dark blue in the latest weekly ice chart below:
The ice is still thin, as the chart below indicates, but that’s how freeze-up starts. As long as strong winds don’t blow the ice away (as it sometimes does at this stage), the ice gets thicker day by day — and advances further and further off shore. Polar bears get out on the ice as soon as they are physically able, when the ice is about 3-4 inches thick (about 10 cm) or less.
Below is a video of a bear traversing that thin ice yesterday (1 November 2017), near Churchill. Is this a portend of a freeze-up date as early as occurred in the 1980s?
This year’s baseless media frenzy over walrus survival and loss of summer sea ice blamed on human-caused global warming was initiated by a press release from US Fish and Wildlife last week (16 August 2017, pdf here: “Pacific walruses haul out near Point Lay earlier than in previous years“). Quote below, my bold:
In the first week of August, several hundred Pacific walruses were observed on a barrier island near the Native Village of Point Lay, a small, Iñupiaq community on the northwest coast of Alaska. This is the earliest date yet for the haulout to form…This year, sea ice has retreated beyond the continental shelf earlier than in previous years
But is this all true? In a word, no — and it didn’t take much research to uncover the truth.
UPDATE 24 August 2017: A few minutes after this post was published, I became aware that just yesterday, 20 conservation activist organizations, lead by the Center for Biological Diversity (who led the polar bear listing charge) issued a press release regarding a letter (pdf here) pressuring the US Fish and Wildlife Service to list Pacific walrus as threatened or endangered under the Endangered Species Act. Apparently, a decision must be made by the end of September on whether to actively list walrus or not. The text below has been amended to reflect this development.

For more than ten years, we’ve endured the shrill media headlines, the hyperbole from conservation organizations, and the simplistic platitudes from scientists as summer sea ice declined dramatically while polar bear numbers rose.
Now, just in time for International Polar Bear Day, there’s a video that deconstructs the scare. It runs about 8 minutes, written and narrated by me, produced by the Global Warming Policy Foundation.

Update 28 February 2017 See my follow-up post for the science behind the video, featuring a new version of my sea ice/polar bear hypothesis paper, just published (and updated with new data).
Crockford, S.J. 2017 V3. 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).

This new effort by the BBC would make the PR department of the Center for Biological Diversity proud, with it’s prominent use of animal tragedy porn pretending to be science. In contrast, the actual science shows something quite different: though summer sea ice since 2007 has declined to levels not predicted until 2040-2070, there has been virtually no negative impact on polar bear health or survival, a result no one predicted back in 2005.
Bizarrely entitled “A 3-million-year ice age is coming to an end“ (15 September 2016), this slick video pretends it’s promoting the recently released paper by Harry Stern and Kristen Laidre (2016) that got a lot of media attention last week (see here and here).
Who exactly suggested the profound prophesy stated in their chosen title, the BBC Earth folks don’t say: the Stern and Laidre paper certainly does not. And the use of a bear that appears to drown before our eyes is Hollywood-style emotional manipulation. Note the careful use of “might” (above) and “could” (below).
Watch the videos below and weep not for the plight of the polar bear, but for the downfall of science journalism. Continue reading

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:
We are not talking about a difference of opinion or interpretation but a simple fact that was outrageously wrong by a wide margin. You see it, don’t you? Continue reading
