Polar bears onshore in Svalbard in most dangerous season for bear attacks

Yesterday marked the first report I’ve found for polar bears onshore this winter, in a potentially dangerous repeat of a pattern that has become all-too common in recent years (especially last year) with bear populations booming virtually everywhere (but especially around Svalbard).

This is the leanest time of year for polar bears – fat Arctic seal pups won’t be available for another 2-3 months and meals for polar bears are hard to come by – and that makes the bears especially dangerous.

So, despite the marked lack of sea ice around Svalbard this winter, a female polar bear with two cubs were reported near the community of Longyearbyen (still enduring 24 hours of darkness) – on the west coast of the archipelago (see map above), where sea ice has been virtually non-existent for years (see map below).

It appears these bears traveled overland from ice off the east coast. There is no mention in any of the reports that the bears were thin or in poor body condition, or had so far caused any of the problems for which desperately hungry polar bears are famous. However, one dog-sledding guide had a frightening encounter in the dark in this on-going saga that began over the weekend (details and photos below). Continue reading

Polar bear habitat update and attempts to spoil the good news for kids

The trolls are out in force at Amazon, posting negative reviews of my new book, Polar Bear Facts & Myths – they just hate it when credible scientists won’t promote a message of doom. It seems folks of this ilk truly want children to have nightmares about drowning, starving polar bears; they encourage kids to frantically turn out lights in a vain attempt to “Save The Sea Ice” while unbeknownst to them, the polar bears and seals prosper.

I expect those same fear-mongers will really hate my next book, due to be released early next week, because it presents the evidence in a way all readers will understand with the references to back it up. Polar bears and ringed seals are thriving despite recent losses of summer sea ice and there is seemingly a huge body of activists and scientists who don’t want people to know that simple fact.

Coming soon    Polar Bears: Outstanding Survivors of Climate Change

Back to polar bear habitat news, here is the sea ice map for 30 December 2016: Hudson Bay iced-over and lots of ice moving down southern Davis Strait:

Compare to last year at this time, when polar bears did not die off in droves anywhere in Canada (or we would have heard about it) – remember that 2/3 of the word’s polar bears live in Canada:

Polar Bear Facts & Myths now available and may arrive in time for Christmas

The first science book suitable for kids that tells the whole truth about polar bears and climate change is now for sale at Amazon.

fm_small

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

For adults & high school students (coming soon Now available)

os_small

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.

Hudson Bay could be ice-free in winter within 5-10 years, says seal researcher

Ringed seal biologist Steven Ferguson, in a statement to a reporter from the Winnipeg Free Press, made one of the boldest predictions I’ve ever heard:

crystalball_468x317_predictions_sq

 

“Hudson Bay could experience its first free winter within 5-10 years.”

You heard it here, folks. It appears Ferguson thinks Hudson Bay was never ice-free in winter even during the Eemian Interglacial, when the Bering Sea was ice-free in winter – something that has not come close happening in recent years (Polyak et al. 2010:1769).

Sounds like a bit of ill-advised grandstanding to me.

An El Niño year late start to freeze-up on Hudson Bay: bears gearing up to hunt

There is no serious ice on the west shore of Hudson Bay yet (as the map below shows) but the winds have just shifted – instead of coming from the south, they are now blowing in from the north.

Freeze-up and a resumption of seal hunting for Western and Southern Hudson Bay polar bears looks imminent. The bears get out on the ice as soon as they are physically able, when the ice is about 3-4 inches thick (about 10 cm).

sea-ice-extent-canada-2016-dec-5_cis

I’m going to let Kelsey Eliasson from PolarBearAlley, on shore at Churchill, convey the gist of the freeze-up situation on the Bay.

Recall that freeze-up was late in both 1998 and 1999 – during the height of that strong El Niño warmth as well as the year following. Continue reading

No correlation between freeze-up dates for Hudson Bay & total Arctic ice cover

Guess which year between 2006 and 2016 had the latest start to freeze-up on Hudson Bay, given that 2012 had the lowest September average and 2007 and 2016 tied for second-lowest (see graph below, from NSIDC), and that sea ice in the Arctic right now is the lowest it’s been for this date since 1979?

sea-ice-sept-averages-graph-only-marked-for-2006-up

If you guessed anything other than 2010, you guessed wrong – in addition, 2006 (not 2016) was second latest.

There is no correlation between Arctic sea ice coverage and freeze-up dates for Western Hudson Bay.

Yet, Polar Bears International (“Save Our Sea Ice”) –  who were surely in and around Churchill in 2010 and 2006 watching polar bears – just posted an alarming statement about local conditions, implying that slow freeze-up of Hudson Bay this year is a reflection of the fact that “sea ice is at a record low across the Arctic.”

They also claim that “…the weather is the warmest we’ve ever seen at this time of year.” That may be true, but if so, it is also meaningless with respect to the progress of freeze-up.

Does no one at PBI remember the very late freeze-up of 2010 or 2006? Odd, that.
