International Polar Bear Day is a good day to ask: Are polar bear researchers hiding good news? Extended lags in publishing polar bear counts and a failure to publish data on female polar bear body weights and cub survival in Western Hudson Bay for more than 25 years make it look like polar bear researchers are delaying and suppressing good news.
In particular, the failure to report the data on cub survival and weights of female bears suggests that these health measures have not declined over the last two decades as claimed. If these figures are indeed the strongest evidence that sea ice loss due to climate change is harming Western Hudson Bay polar bears, why on earth have they not been made public? And why won’t a single journalist ask to see that data?

In conjunction with the launch of my State of the Polar Bear Report in Toronto next week, Benny Peiser (from the Global Warming Policy Foundation) and I will be participating in a coffee house discussion about polar bear conservation and survival issues on the evening of Tuesday, 27 February 2018 at 8:30 pm.
If you’re in town, come and celebrate International Polar Bear Day with a frank discussion about polar bear science.
I am very much looking forward to meeting the public at this evening discussion and to chat with media representatives and colleagues at the press luncheon in the early afternoon. Journalist/opinion writer Terry Corcoran recently billed the luncheon as part of a Polar Bear Battle since conservation organization Polar Bears International (where biologist Steven Amstrup, co-author of the Harvey et al. Bioscience paper and developer of the failed 2007 polar bear survival model, is employed as chief scientist) is holding a gala fundraiser dinner the same night, just a block away.
In addition to Benny Peiser from GWPF, a number of familiar names will be at the State of the Polar Bear launch and press luncheon, including Terry Corcoran, Larry Soloman, Joe Oliver and Conrad Black (all journalist/opinion writers at the Financial Post and/or National Post), journalist/writer Donna Laframboise who blogs at No Frakking Consensus, as well as science colleagues Chris Essex, Ross McKitrick, and Steve McIntyre of Climate Audit fame. Details below.

My “State of the Polar Bear Report 2017” will be unveiled at a Global Warming Policy Foundation press conference and luncheon in Toronto on Tuesday, 27 February, in celebration of International Polar Bear Day. There will be a video presentation as well.
The report summarizes clear, reliable and concise information on the current state of polar bears relative to historical records. It highlights up-to-date data and research findings in a balanced and factual format that avoids hype and exaggeration, all in one place. It is intended for a wide audience, including scientists, teachers, students, decision-makers and the general public interested in polar bears and Arctic ecology.
The launch will be held on Tuesday 27 February at 11:00am at the Toronto Public Library, Founders’ Room, 789 Yonge St, Toronto, ON M4W 2G8.
* Welcome (Dr Benny Peiser, Director of the GWPF)
* Introduction: Prof Chris Essex (Chairman of the GWPF’s Academic Advisory Council)
* Short video screening
* Presentation: Dr Susan Crockford (author of the report)
For further information and to schedule interviews, please contact Harry Wilkinson (firstname.lastname@example.org)
A copy of the report will be posted on Polar Bear Science Tuesday.

Walrus researchers from the US Geological Survey have a new report on the history of walrus haulouts in the Chukchi and Bering Seas – yet their media efforts (via press release and interviews) fail to mention the relationship between fluctuating size of walrus haulouts and fluctuating walrus population size that is evident in that history. In fact, overall population size is not mentioned at all.
Two articles came out over the weekend that announced the results of this new joint US-Russian initiative [PBS, Walrus beaching in Alaska might not be as harmful as it looks. Here’s why – 31 July 2016 and ADN, Alaska and Russia join forces to create 160-year database of walrus haulouts – 31 July 2016]
But neither articles nor the new USGS paper they are touting (Fischback et al. 2016) mention the huge summer/fall haulouts of females, calves, and juveniles that were documented in the 1970s that coincided with the huge population size at that time, which crashed in the 1980s.
Only now has the population grown (to at least 200,000) to the point that huge haulouts are again being reported – conservation has done it’s job. But when walrus numbers get too high the animals out-strip their food source and numbers plummet, as they did in the 1980s (Fay et al. 1989; Garlich-Miller et al. 2011). See my fully referenced summary paper, Crockford 2014 (On The Beach: Walrus Haulouts are Nothing New).
Here’s the concern: When (not if) a population crash happens again, will it be blamed on global warming rather than natural causes? According to the PBS article:
“The database is supposed to help federal officials with conservation, especially as more ships start sailing through the newly open waters. The U.S. Fish and Wildlife Service is determining whether walrus should be listed as a threatened species.” [my bold]
