A recent New Time Times article about Google’s practice of generating ad revenue via ‘promoted’ search results (“How Climate Change Deniers Rise to the Top in Google Searches” 29 December 2017) had a surprising and disquieting ending about the prospect of internet censorship.
It was a quote from Jeff Harvey of “Internet Blogs, Polar Bears, and Climate-Change Denial by Proxy” (Bioscience, 29 November 2017) fame:
Here are some suggestions, by myself and others. See the sidebar for my offerings, not forgetting “Polar Bears Have Big Feet” for the toddlers in your life, so they don’t feel left out when older kids get polar bear books to read over the summer: Facts & Myths for middle school ages, and Outstanding Survivors and/or EATEN (the polar bear attack thriller) for teens and adults.
Titles from other authors that have a few mentions of polar bears amid great descriptions of life in the Arctic or Arctic exploration that would make good summer reading as well. Continue reading
I knew it was coming up and then forgot to check, but sometime about 2 weeks ago blog views here at PolarBearScience passed the one million mark — more than two months ahead of my 5th anniversary.
Over 1 million views, four polar bear books (including my first novel, the polar bear attack thriller EATEN), several white-paper type publications (here, here, and here), several magazine articles (one here), two videos (see below), and a scientific paper on polar bear conservation that was peer reviewed before it’s publication at PeerJ Preprints.
Not bad for a five year stint on a blog with a single species focus. Continue reading
Apparently, some locals were upset that a polar bear that refused to be scared away from a Newfoundland community over the weekend was shot as it advanced on conservation officers and a crowd of onlookers who refused to disperse (see updated report here on recent Newfoundland polar bear sightings, with annotated map).
“Polar bear shot by wildlife officers near Catalina after being deemed public safety risk” (CBC 10 April 2017)
What these animal lovers may not realize is that Newfoundland in March and April is not a Churchill-like situation: polar bears are in strong hunting mode right now.
Polar bears in late winter and spring have an immense drive to kill and eat as much as possible. Even bears that look well fed will continue to kill and eat. Enticing smells attract them onshore as they investigate any food possibility (see list below).
Seriously, you don’t want that food possibility to be you.
Polar bears can go from watching to charging, in the blink of an eye. You can’t outrun one. Killing quickly is what they do and they are immensely strong. Polar bears generally go for a killing bite to the head. Things to think about when a polar bear is prowling your community…

Yesterday, the DailyMail (among others) was suckered into running virtually the same story The Guardian (among others) hyped last year about this time.
Using a science journal version of the 2015 IUCN Red List assessment report, polar bear data collectors and their fortune-teller colleagues have managed to get polar bears back in the news.
I wrote about this last year – it’s actually good news, although you wouldn’t know it from the headlines.
Let me paraphrase the ‘sperts:
“After 10 years of ice conditions we didn’t expect would happen until mid-century (a worst-case scenario we said would cause more than 30% of the world’s polar bears to die – except they didn’t), we have now determined (using a new model and a brand new definition of sea ice specific to polar bears) that by mid-century, there is only a 70% chance that 30% of polar bears will die.”
This is how they explain away all the bears that didn’t die as they should have when summer sea ice declined to about 5 mkm2 and below after 2006.

It appears that the male polar bear with a too-tight satellite radio collar that was photographed late last year near Kaktovik on the North Slope of Alaska has been captured and his faulty collar removed, says a statement posted on the University of Alberta website 25 August 2016. The animal was reported to be healthy and behaving normally.
As far as I can tell, no press release was issued and no media interviews have been conducted despite the strong interest in the fate of this bear last fall (previous reports here, here, and here) – I found the notice by accident while looking for something else.
Andrew Derocher and his research team from U of A have admitted they collared this bear and the Polar Bear Facts webpage where this recent statement appears was developed to deal with the many inquiries about the status of this bear (dubbed “Andy” by some).
Note the statement, copied below, does not confirm that this is indeed the same bear as was photographed last year – they just assume it is. No photo is provided of the rescued bear, although clearly some were taken. However, if it is not the same bear, then another subadult male spent the winter of 2015-2016 on the ice of the Beaufort Sea with a tight and non-functioning collar that was not about to fall off by itself.
A part-time Arctic researcher eager for media attention suggested earlier today that the ice entrapment of narwhals in 2008 and again in 2015 at Pond Inlet (that made headlines around the world) was the result of “sudden changes in temperature” caused by climate change. This grossly misleading claim ignores the facts: ice entrapment of narwhals is an entirely natural feature of the Arctic that has been known about for hundreds of years.
“Narwhals: the ‘giant unicorn of the sea’ at risk from climate change” (CBC, 13 August 2016), a print version of a CBC Radio interview with Clint Wright that aired 8 August 2016. Wright is the general manager at the Vancouver Aquarium and apparently has “joined a team of researchers to tag and study” narwhals for several years – but does not seem to know much about the history or circumstances of natural ice entrapment.
Ice entrapment of small whales is nothing new. The first formally documented incident – in English – occurred in 1915 (Porsild 1918) and the phenomenon has probably occurred as long as there has been ice in the Arctic (millions of years).
Animals routinely become trapped in a few specific areas due to local geography: when ice that forms in the north moves south quickly, it blocks the entrances to inlets or coastal bays that still have open water. The presence of the pack ice causes nearby temperatures to drop quickly. Rapid development of ice on the bay proceeds from the mouth toward the head of the bay. Any whales present cannot escape to open water and will eventually die or be eaten.
Pond Inlet at the north end of Baffin Island is one such place but Disko Bay in western Greenland is another. In fact, Pond Inlet and Disko Bay are almost identical in geographic layout even though they lie on opposite sides of Baffin Bay, so it’s not surprising that both are locations of repeated entrapment events.
Three highly informative journal articles on the phenomenon of ice entrapment of narwhals and beluga are open access documents that reveal some fascinating details of such incidents, including polar bear predation on trapped whales. h/t T. Nelson Continue reading
