Fancy that! After a load of handwringing earlier this month, mobile pack ice in the Bering Sea has returned. Just like ice in the Barents Sea, Bering Sea ice is highly variable (Brown et al. 2011): it moves with winds and currents, so a ‘decline’ during the winter usually indicates redistribution, not melting.

According to researcher Rick Thoman from the University of Alaska Fairbanks, quoted by the Canadian Press:
“Wind blew ice to Russian beaches in the west and to the south side of Norton Sound south of Nome but left open water all the way to Chukchi Sea north of the Bering Strait.”
Polar bears that venture into the Bering Sea are part of the Chukchi Sea subpopulation, which is known to be thriving (Crockford 2019; AC SWG 2018; Regehr et al. 2018; Rode and Regehr 2010; Rode et al. 2013, 2014, 2015, 2018).

The Polar Bear Catastrophe That Never Happened is almost here! The book is scheduled for release (in paperback and ebook formats) on Tuesday 19 March 2019. Tuesday is also the day I’ll be talking to Glenn Beck on his radio show (11 am ET) about polar bear population numbers and my book. How many polar bears are really out there now, you ask? My book has a credible new answer that may surprise you.
The official book launch event will be 10 April in Calgary, just ahead of the annual Friends of Science Climate lecture evening, where I’ll be presenting alongside astrophysicist Willie Soon. You can pick up an autographed copy of The Polar Bear Catastrophe That Never Happened there.

Abundant ice in Svalbard, East Greenland and the Labrador Sea is excellent news for the spring feeding season ahead because this is when bears truly need the presence of ice for hunting and mating. As far as I can tell, sea ice has not reached Bear Island, Norway at this time of year since 2010 but this year ice moved down to the island on 3 March and has been there ever since. This may mean we’ll be getting reports of polar bear sightings from the meteorological station there, so stay tuned.
Sea ice extent as of 11 March 2019, from NSIDC Masie:
Much of the ice that was blown out of the Bering Sea early in the month has returned and ice in the Gulf of St. Lawrence on the East Coast of Canada is the highest its been in years, threatening to impede ferry traffic between Nova Scotia and Newfoundland, as it did in 2015 and again in 2017. The fishing season off Newfoundland might also be delayed by the heavy ice, as it was in 2017.

Polar Bear Facts and Myths (for children aged 7 and up) is now avaiblable in Norwegian!
The same day as a glowing review of the Dutch translation of my popular children’s science book appeared in de Telegraaf (front page and all of page 5, 19 November 2018, pdf here), I am thrilled to announce that this important book is now available in Norwegian via Amazon worldwide, including European outlets.
The translation was done by native Norwegian speakers Arve Tunstad and Morten Jødal. In Norwegian the book is called ISBJØRN Fakta og Myter.
Please pass along to your friends, relatives, and colleagues in North America and abroad (calling all Sons of Norway). The English version is still available in paperback and ebook formats. Other translations in French and German are already available: five languages in all, including Dutch.
Details below on the Norwegian version. Continue reading
Given my strong Dutch heritage through my maternal grandfather (via Middelharnis), I am especially proud to announce that the Dutch translation of my popular science book, Polar Bear Facts and Myths (suitable for children aged seven and up), is now available through Amazon worldwide in paperback.
The translation was done by native Dutch speaker Marcel Crok who is a journalist and science writer in The Netherlands (see @marcelcrok on twitter). In Dutch the book is called Feiten en Mythes over IJsberen.
Please pass along to your friends, relatives, and colleagues in North America and abroad. The English version is still available in paperback and ebook formats, and the Norwegian translation will be available shortly. Other translations in French and German are already available.
Why this book is important
Children around the world have been led to believe that only a few hundred polar bears are left in the world. However, the relentless messaging that polar bears are doomed (and that this is all the fault of humans) is fortunately false. It is time that children learned the truth, including those that speak and read only Dutch.
Here is the good news the children need to hear: polar bears have not been driven to the brink of extinction by anthropogenic global warming. In fact, there are many more polar bears now than there were 50 years ago and the global population of polar bears is a healthy size, despite the fact that summer sea ice has been at levels predicted to cause catastrophe since 2007. Polar bears have managed just fine with low summer ice: against all expectations, their number have increased in recent years, not declined.
Polar Bear Facts & Myths is an uplifting science book about survival in the Arctic that is sure to please children and parents alike.

Starvation due to natural causes is the leading cause of death for polar bears and loss of body condition (getting thinner) is therefore the first symptom of impending death for virtually all polar bears that die naturally. However, polar bear specialist Andrew Derocher claims that loss of body condition is also the first symptom of climate change for polar bears.
But how do you tell the difference between polar bears made thin by man-made climate change and those who are thin due to natural causes?
You can’t. Even a necropsy will not be conclusive because there are so many natural reasons for a bear to lose weight — and even starve to death — that’s it’s virtually impossible to say that any thin bear is skinny due to a lack of sea ice.
Emaciated polar bears like the one above from Somerset Island in the Canadian Arctic,1 captured on camera in August 2017, are being used to promote the idea that polar bears are already dying of starvation due to climate change. That’s a big white lie, as the headline above suggests: seven months later, National Geographic has admitted as much. Here I show why it could not have been true in the first place (with references from the scientific literature).
