Posted onMay 6, 2022|Comments Off on Ancient polar bear remains explained by sea ice and polynyas: my peer-reviewed paper
My open-access, peer-reviewed paper on the ecology of ancient polar bears in relation to sea ice has just been published in Open Quaternary. It’s called ‘Polar Bear Fossil and Archaeological Records from the Pleistocene and Holocene in Relation to Sea Ice Extent and Open Water Polynyas’.
A unique compilation of more than 104 polar bear skeletal records from the Holocene and late Pleistocene shows that most ancient remainsare associated with existing or ancient open water polynyas or the expansion of sea ice during past cold periods. This big-picture analysis indicates that as they do today, polar bears were most commonly found near polynyas throughout their known historical past because of their need for ice-edge habitats.

Posted onSeptember 1, 2021|Comments Off on My new science book for kids Walrus Facts & Myths is available now!
I am thrilled announce that my new science book for kids, Walrus Facts & Myths is now available for sale on Amazon. This unique book fills an enormous need.
Thanks to media reports and television documentaries – here’s looking at you David Attenborough – many children around the world have been led to believe that walrus are dying in large numbers every year because of reduced sea ice. This has left kids feeling despondent and powerless. The relentless messaging that walrus are doomed (and that it’s all the fault of humans burning fossil fuels) is fortunately false. It’s time the children learned the truth and now, there’s a book for that!
This is a walrus science book for kids with lots of great photos and a format that readers of all ages will enjoy.
My nonfiction book for adults Fallen Icon: David Attenborough and the Walrus Deception, will be released in a few weeks but here is a science book just for the kids. If the children in your life enjoyed Polar Bear Facts & Myths, I’m sure they’ll love this one too. The colour photos are beautiful and engaging. It’s also perfect for homeschoolers wanting to learn about Arctic ecology and walrus life history.
Posted onOctober 14, 2016|Comments Off on New ecology book: 25 MYTHS THAT ARE DESTROYING THE ENVIRONMENT
Veteran Yale University research ecologist Dan Botkin has a new book coming out tomorrow (Saturday 15 October) that you might want to look at:
A number of chapters are relevant to polar bears, including these three:
“Myth 11: Without Human Interference, Earth’s Climate is Stable”
“Myth 13: Climate Change Will Lead to Huge Numbers of Extinctions”
“Myth 25: Compared to Climate Change, All Other Environmental Issues Are Minor”
I found the book clearly written in a readable style (Table of Contents here). It provides timely insight into critical issues related to conservation and species extinction, with many real-world examples that counter theoretical assumptions (polar bears are discussed in the Overview). I found the energy issues (Myths 23 and 24) an awkward distraction but others might find them of interest. It’s a good companion to Bjorn Lomborg’s The Skeptical Environmentalist (an excellent reference from 2001 but much more detailed).
Pre-0rders now being taken:
Twenty-five Myths That Are Destroying the Environment: What Many Environmentalists Believe and Why They Are Wrong. Daniel B. Botkin 2017. Rowman & Littlefield Publishers, Inc., Lanham, MD 20706. $12.71 PAPERBACK; $7.51 KINDLE

Posted onJune 8, 2015|Comments Off on My new Arctic Fallacy paper- Sea ice stability and the polar bear
I have a new paper out that explains a fundamental problem with polar bear conservation.
I’m convinced that a flawed and out-dated ecological concept — that sea ice, under natural conditions, provides a stable, predictable habitat — is what has allowed the present doom and gloom attitude of most polar bear specialists to develop.
Sea ice changes, of course, from season to season. However, the concept that sea ice is a stable habitat assumes that these seasonal changes are predictable and virtually the same from one year to the next – at least, similar enough that the differences are not responsible for causing marked declines in population size.
The assumption is that under natural, stable conditions populations of Arctic animals will either stay the same over time or increase. Biologists were taught at university that sea ice should be a stable habitat and as a result, they’ve glossed over evidence they collected to the contrary. [see recent posts here and here, for example]
Negative effects on populations of short-term natural variations in spring sea ice or spring snow cover on sea ice have been entirely ignored in modeled predictions of future conditions. The focus has been on summer ice extent.
I have summarized this evidence in a fully referenced, peer-reviewed essay that explores how the acceptance of this fallacy (“sea ice is a stable habitat”) has so skewed the conservation biology of polar bears that to outsiders it may look like a scientific integrity issue.
The summary and the essay are below (with embedded links and references). The Global Warming Policy Foundation (GWPF) has published the essay in their “Briefing Paper” series (#16, The Arctic Fallacy: Sea Ice Stability and the Polar Bear), which includes a must-read foreword by Dr. Matthew Cronin, Professor of Animal Genetics at the University of Alaska Fairbanks. Press release here, pdf here.
I think you’ll find it timely and thought-provoking.
