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.

The first science book suitable for kids that tells the whole truth about polar bears and climate change is now for sale at Amazon.
This beautiful, full color summary (44 pages, 8 x 10 inches) explains in simple terms why polar bears are thriving despite the recent loss of Arctic sea ice. It’s written in a question and answer format, in language that readers of all ages can understand (age 7 and up). The book takes a sensible, big-picture approach that many readers will appreciate and is based on the most up-to-date information available.
This is the perfect gift for some of the polar bear lovers on your gift list and if you act quickly (order here), your book may arrive before the 25th. At this time, only the paperback is available but some ebook versions should be out shortly.
For purchasers for which a pre-Christmas delivery isn’t going to work (publication will be later in Europe; shipping is faster to eastern Canada and the US than to the west), I have provided a gift card you can download to print off and give in lieu of the physical book (kind of a placeholder until it arrives).
UPDATE: 18 Dec. 2016 Now listed at Amazon Canada and Amazon UK
Download gift card PDF HERE for Polar Bear Facts & Myths
Download gift card PDF HERE for Polar Bears: Outstanding Survivors of Climate Change (coming soon, see below).
[Download Christmas gift cards, one per page, for both books here]
Check my book website for updates.
For adults & high school students (
coming soon Now available)
This color, fully-referenced polar bear science book is aimed at adults and high school students. Polar Bears: Outstanding Survivors of Climate Change is fashioned after the popular lecture with the same title I have given since 2009, which has been enthusiastically received by audiences with diverse backgrounds.
My book website now has full details of these new non-fiction books (along with a revised author biography) and will be updated regularly regarding formats and venues as they become available. Details for EATEN on that site has moved to its own fiction page.

Here’s a new resource for cooling the polar bear spin, all in one place. I’ve updated and expanded my previous summary of reasons not to worry about polar bears, which is now two years old. In it, you’ll find links to supporting information (including previous blog posts of mine that provide background, maps and extensive references), although some of the most important graphs and maps have been copied into the summary. I hope you find it a useful resource for refuting the spin and tuning out the cries of doom and gloom about the future of polar bears — please feel free to share. Pdf here of the text below.
This is the 1st anniversary of Canada providing population estimates and trends independent of the pessimistic prognostications of the IUCN/SSC Polar Bear Specialist Group (PBSG) — so let’s celebrate the recent triumphs and resilience of polar bears to their ever-changing Arctic environment.

The polar bear biologists and professional activists of the IUCN Polar Bear Specialist Group (PBSG) continue to insist that since 1979 increasingly smaller amounts of Arctic sea ice left at the end of summer (the September ice minimum) have already caused harm to polar bears. They contend that global warming due to CO2 from fossil fuels (“climate warming” in their lexicon) is the cause of this decline in summer ice.
In a recent (2012) paper published in the journal Global Change Biology (“Effects of climate warming on polar bears: a review of the evidence”), long-time Canadian PBSG members Ian Stirling and Andrew Derocher (both of University of Alberta) summarized their position this way:
“Climate warming is causing unidirectional changes to annual patterns of sea ice distribution, structure, and freeze-up. We summarize evidence that documents how loss of sea ice, the primary habitat of polar bears (Ursus maritimus), negatively affects their long-term survival”
I’ve spent the last year examining their evidence of on-going harm, but in addition, I’ve looked at the evidence (much of it not mentioned in the Stirling and Derocher paper1) that polar bears have either not been harmed by less sea ice in summer or have thrived in spite of it.
This is a summary of my findings. I’ve provided links to my original essays on individual topics, which are fully referenced and illustrated. You are encouraged to consult them for complete details. This synopsis (pdf with links preserved, updated; pdf with links as footnotes, updated) complements and updates a previous summary, “Ten good reasons not to worry about polar bears” (pdf with links preserved; pdf with a foreword by Dr. Matt Ridley, with links as footnotes).
Update 8 September 2013: to include links to my post on the recently published Chukchi population report; updated pdfs have been added above.
Update 22 January 2014: added figure comparing March vs. September sea ice extent using the same scale, from NOAA’s “2014 Arctic Report Card,” discussed here.

IMPORTANT UPDATE March 13, 2013 Benny Peiser over at the Global Warming Policy Foundation has just posted an essay by well-known author Matt Ridley, entitled “We should be listening to Susan Crockford” which is included as a foreword to a pdf of this very post (“Ten good reasons not to worry about polar bears”), suitable for sharing. I encourage you to have a look.
[Update September 28, 2013: See also this follow-up post “Polar bears have not been harmed by sea ice declines in summer — the evidence.”]
This year marks the 40th anniversary of the signing of an international agreement to protect polar bears from commercial and unregulated sport hunting. The devastating decades of uncontrolled slaughter across the Arctic, including the Bering Sea, finally came to an end. And so in honor of International Polar Bear Day (Wed. February 27) – and because some activists are calling 2013 The Year of the Polar Bear – I’ve made a summary of reasons not to worry about polar bears, with links to supporting data. I hope you find it a useful resource for tuning out the cries of doom and gloom about the future of polar bears and celebrating their current success.
