Apparently, polar bears are attracted to tanks as they are to ships and submarines, which made them easy targets for men with guns. This, along with the rather extensive use of so-called ‘set guns’ (a baited apparatus fixed with a loaded shotgun), led to a significant decline of polar bears in the U.S.S.R. and the Barents Sea area by the 1950s. See also, “The slaughter of polar bears that rarely gets mentioned (ca. 1890-1930)”

This was the real threat to polar bears and it was successfully halted by international agreement in 1973. We should not forget that polar bears are a conservation success story.

Hudson Bay freeze-up 2014 – average again this year, not late

Posted on November 13, 2014 | Comments Off on Hudson Bay freeze-up 2014 – average again this year, not late

Freeze-up of Hudson Bay sea ice is well underway now, virtually the same time as it was the last three years, and in 2008. Bears in the north will be able to move out, while near Churchill and in Southern Hudson Bay, some bears will be able to successfully hunt for seals on the newly-formed ice close to shore.

Over the next week or so, all the bears onshore will gradually move out onto the ice as freeze-up progresses. By the time there is ~10% ice coverage on the bay, most bears will have moved onto the ice (except pregnant females that have made dens onshore).

The Arctic outbreak underway in over North America may hasten this process along (see 7-day and 14-day weather forecasts for Churchill). Ice maps below courtesy Canadian Ice Service.

It seems pretty clear now that time of freeze-up on Hudson Bay is not correlated with the extent of sea ice at the September minimum. Have a look at the maps and graphs below.  UPDATE: more recent maps added below (ice concentration 15 November; ice development 14 November).

“Meltdown: Terror at the Top of the World” — new book exploits polar bear attack to sell fear of sea ice decline

Posted on November 13, 2014 | Comments Off on “Meltdown: Terror at the Top of the World” — new book exploits polar bear attack to sell fear of sea ice decline

The polar bear attack that was all over the news last summer is now an ebook about global warming. The Maine lawyer who was mauled by a bear while on a hiking trip to Labrador (and lived to tell the tale) has allowed his story to be co-opted by an activist journalist to promote fears of sea ice decline, polar bear extinction, and man-made global warming.

Melt-down_Terror at the Top of the World_Nov 12 2014 press release book cover

The press release issued yesterday by the news group that published the book and employs author Sabrina Shankman (InsideClimateNews), described it this way:

“A riveting new e-book about the battle between man, beast and Nature in a warming world. Called Meltdown: Terror at the Top of the World, the e-book tells the story of the hikers’ harrowing encounter with a polar bear; of the plight of the polar bear in general, facing starvation and extinction as the sea ice melts and its habitat disappears; and of the Arctic meltdown, the leading edge of man-made climate change.”

I have little doubt the man mauled by the bear was indeed terrified and that his companions were as well. However, that horror is exploited shamelessly in this book as a means to promote anxiety over the future survival of polar bears and instill panic over a prophesied Arctic “meltdown.”

A more optimistic view of Churchill polar bears and Hudson Bay freeze-up

Posted on November 11, 2014 | Comments Off on A more optimistic view of Churchill polar bears and Hudson Bay freeze-up

Finally, an unbiased first-hand report about Churchill polar bears and freeze-up on Hudson Bay.

Over the last few weeks, biologists Andrew Derocher and Steve Amstrup have been repeating their tired old tales of doom and gloom about the polar bears around Churchill and I’ve done my best to refute the worst of their nonsense.

To that effort we can now add this report from PolarBearAlley, where Kelsey Eliasson has posted a good-news story about the bears of Cape Churchill and the progress of freeze-up, including sightings of a number of mothers with cubs.

Polar bear listed as a migratory species by UNEP to restrict oil exploration & extraction

Posted on November 9, 2014 | Comments Off on Polar bear listed as a migratory species by UNEP to restrict oil exploration & extraction

In a press release this afternoon, the Convention on the Conservation of Migratory Species of Wild Animals (CMS) announced it had added polar bears to their list of Appendix II migratory species. [CMS is a pseudo-arm of the UN Environment Programme, the UNEP1]

polarbear_new_USGS
“The Polar Bear, the largest apex predator on Earth is affected by climate change that has led to the loss of 2 million m2 of sea ice. The Appendix II listing introduces the global perspective of existing threats to Arctic species stemming from shipping and oil exploration, making it a case for all CMS Parties.“

But why formally list the polar bear as a migratory species when it is protected under several other national and international programs?

BBC provides a forum for desperate biologists: “Will polar bears become extinct?”

Posted on November 7, 2014 | Comments Off on BBC provides a forum for desperate biologists: “Will polar bears become extinct?”

Yesterday, the BBC published a story that gave the two most alarmist polar bear researchers on the planet a forum to market their ‘polar bears are doomed’ message. This time the desperation shows: watch how these biologists move the goal-posts, make claims so misleading they border on lies, and pretend they don’t have big, big trouble with their predictive models.

Polar bear specialist says there are 800 polar bears in W Hudson Bay, gov’t says ~1,000-1,500

Posted on November 5, 2014 | Comments Off on Polar bear specialist says there are 800 polar bears in W Hudson Bay, gov’t says ~1,000-1,500

Activist polar bear biologist Andrew Derocher (University of Alberta) may have gone too far this time. In an interview with Yahoo News, Derocher is quoted as saying:

“When I first started here about 30 years ago the population was about 1,200 bears and now we’re down to about 800,” team member Andrew Derocher, a biology professor at the University of Alberta, said in a phone interview from the tundra outside Churchill.”  [my bold]

However, the Polar Bear Technical Committee of Environment Canada says differently: it estimates there are ~1000-1,500 bears in Western Hudson Bay (WH) and that the population is probably stable, as their new status map (dated June 2014, copied above) shows. A recent (2014) peer-reviewed paper by Stapleton and colleagues (discussed here) provides the data for that estimate.

Polar bear habitat update: what a difference a year makes to sea ice coverage in Canada!

Posted on November 4, 2014 | Comments Off on Polar bear habitat update: what a difference a year makes to sea ice coverage in Canada!

There is far more ice — and far more concentrated ice — in Canada this year than on this day last year. That’s good news for most polar bear populations.

[And, it turns out, more ice total this year on this date than there has been since 2001!]

Polar bear biologists doing mark-recapture work in Hudson Bay may have misled the world

Posted on November 2, 2014 | Comments Off on Polar bear biologists doing mark-recapture work in Hudson Bay may have misled the world

What exactly are Western Hudson Bay (WHB) polar bear researchers hiding? Since 2004, research on the body condition and cub production of Western Hudson Bay (WHB) polar bears has been carried out but none of the results of these mark-recapture studies have been made public.

The researchers all claim that WHB polar bears are struggling to survive because of recent sea ice changes but won’t release the 10 years worth of updated information they possess on the bears or the sea ice.

W Hudson Bay polar bear population no longer “declining” – where are the headlines?

Posted on October 29, 2014 | Comments Off on W Hudson Bay polar bear population no longer “declining” – where are the headlines?

Why are the #saveourseaice folks at Polar Bears International, who have being working in Western Hudson Bay for decades, not dancing in the streets of Churchill? Environment Canada’s Polar Bear Technical Committee upgraded the status of Western Hudson Bay polar bears from “declining” to “likely stable” four months ago (details here). Why has this fabulous news not made major headlines around the world?

Figure 4. Environment Canada's "Map 3: 2014 Canadian Polar Bear Subpopulation and Status Map," original here.

Figure 1. Environment Canada’s “Map 3: 2014 Canadian Polar Bear Subpopulation and Status Map,” original here. Western Hudson Bay is “WH.”

After years of being told by polar bear specialists and activists organizations like Polar Bears International and the World Wildlife Fund that the Western Hudson Bay (WHB) population is already suffering mightily because of global warming, it now appears that is far from the truth.
