There is now enough sea ice off southern Labrador and the northern tip of Newfoundland for Davis Strait polar bears to come ashore looking for food. Baby seals won’t be available for months yet. And since winter is the lean season for these bears, some may seek food sources onshore. The bears come down from the area of Hudson Strait and southern Baffin Island: as the sea ice expands south, so do the bears.
Not all polar bears are in the same dire situation due to retreating sea ice, at least not right now. Off the western coast of Alaska, the Chukchi Sea is rich in marine life, but the number of polar bears in the area had never been counted. The first formal study of this population suggests that it’s been healthy and relatively abundant in recent years, numbering about 3,000 animals.
The study by researchers at the University of Washington and federal agencies is published Nov. 14 in Scientific Reports, an open-access journal from the Nature Publishing Group.
“This work represents a decade of research that gives us a first estimate of the abundance and status of the Chukchi Sea subpopulation,” said first author Eric Regehr, a researcher with the UW’s Polar Science Center who started the project as a biologist in Alaska with the U.S. Fish and Wildlife Service. “Despite having about one month less time on preferred sea ice habitats to hunt compared with 25 years ago, we found that the Chukchi Sea subpopulation was doing well from 2008 to 2016.

There are too many polar bears in parts of Nunavut and climate change hasn’t yet affected any of them, says a draft management plan from the territorial government that contradicts much of conventional scientific thinking.
The proposed plan — which is to go to public hearings in Iqaluit on Tuesday — says that growing bear numbers are increasingly jeopardizing public safety and it’s time Inuit knowledge drove management policy.
“Inuit believe there are now so many bears that public safety has become a major concern,” says the document, the result of four years of study and public consultation.

A draft plan from the Nunavut government says growing bear numbers are increasingly jeopardizing public safety.
Ten years ago, polar bears were classified as an endangered species due to model-based assumptions that said the recession of Arctic sea ice would hamper the bears’ seal-hunting capabilities and ultimately lead to starvation and extinction.
The Inuit, who have observed these bears catch seals in open water for generations, disagree. At least this is what scientists have found upon investigation.
“There is no evidence that the fast reduction of sea-ice habitat in the area has yet led to a reduction in population size.” (Aars et al., 2017 )
Inuit observations: “… back in early 80s, and mid 90s, there were hardly any bears … there’s too many polar bears now. Bears can catch seals even—even if the—if the ice is really thin … they’re great hunters those bears … they’re really smart … they know how to survive.” (Wong et al., 2017)
We’ve hit the seasonal Arctic sea ice minimum for this year, called this morning by US NSIDC for 19th and 23rd of Septmeber: 4.59 mkm2, the same extent as 2008 and 2010. This is not a “ho-hum” year for polar bears: it means that since 2007, they have triumphed through 10 or 11 years1 with summer ice coverage below 5.0 mkm2 — levels that in 2007 were expected to cause catastrophic declines in numbers.
Opinion: New facts have emerged from the filmmaker behind the cruel and deliberate exploitation of a dying bear in quest to advance climate change agenda.
It was tragedy porn meant to provoke a visceral response — the gut-wrenching video of an emaciated polar bear struggling to drag himself across a snowless Canadian landscape made billions of people groan in anguish. Taken in August 2017 by biologist Paul Nicklen, a co-founder of the Canadian non-profit SeaLegacy, the video was posted on Instagram in December 2017, stating “This is what starvation looks like” as part of a discussion about climate change.

Il y a juste un an, l’image d’un ours décharné et titubant avait fait le tour du monde. Elle était supposée représenter la réalité du réchauffement de l’atmosphère. Pourtant cette hypothèse n’était pas plus probable qu’une autre, par exemple: ours vieux, malade, mourant de mort naturelle.
SPOTLIGHT: The iconic magazine is now a purveyor of propaganda.
BIG PICTURE: On her PolarBearScience.com blog last week, zoologist Susan Crockford called our attention to a startling admission over at National Geographic. It acknowledges publishing fake news. Or, as it more delicately puts it, we “went too far in drawing a definitive connection between climate change and a particular starving polar bear.”
An “Editor’s Note” explains the magazine added a wholly misleading caption to a video of an emaciated polar bear filmed last August. When it published this video on its website in December, National Geographic declared: “This is what climate change looks like.”
Actually, this is what dishonesty looks like. Neither the magazine nor the person who did the filming knew anything about that bear. It might have been stricken with disease. It might have sustained an injury that impeded its ability to hunt. As the Editor’s Note now admits: “there is no way to know for certain why this bear was on the verge of death.”
Remember that video of an emaciated Baffin Island polar bear that went viral last December? In an unexpected follow-up (“Starving-Polar-Bear Photographer Recalls What Went Wrong“; National Geographic, August 2018 issue), photographer Cristina Mittermeier makes some astonishing admissions that might just make you sick.
Susan Crockford uncovers the truth behind that “starving polar bear video”
According to the Guardian (9 July 2018), there is a “global heat wave” going on right now.
In Siberia, the heat is supposedly “completely unprecedented” and will surely (we are told) impact Arctic sea ice — the habitat of the iconic polar bear. Yet a comparison of previous years shows little to no impact on sea ice: there is more ice present than there was in 2007.
Les ours polaires (Ursus maritimus) sont souvent utilisés dans le débat concernant le réchauffement climatique qui serait provoqué par l’homme. Selon les écologistes et les partisans du GIEC ils sont en grand danger. Mais n’est-ce pas aller un peu vite?
DDuring a meeting of polar bear range states (Canada, Russia, Greenland, Norway, and the USA) in late January 2018 to discuss conservation issues, Canada — home to ~2/3 of the world’s polar bears — included in its presentation an updated population status and trend map approved by the Polar Bear Technical Committee in its presentation. This 2017 map replaces one from 2014 but is not yet available on the Environment Canada website.
New evidence from clams and mussels with temperature-sensitive habitat requirements confirm that warmer temperatures and less sea ice than today existed during the early Holocene period about 10.2–9.2 thousand years ago and between 8.2 and 6.0 thousand years ago (based on radio carbon dates) around Svalbard. Barents Sea polar bears almost certainly survived those previous low-ice periods, as they are doing today, by staying close to the Franz Josef Land Archipelago in the eastern half of the region where sea ice is more persistent (…)
So it is no surprise that Erica Goode at the New York Times sided up with the 14 scientists of the Harvey publication to attack the so-called climate “denialists” in her most recent article. Unfortunately Goode made the fatal journalistic error of failing to keep a healthy distance from the alarmist side and as a result was blinded from seeing the glaring mountain of scientific research showing polar bears are in fact doing fine.
