Five facts that challenge polar bear hybridization nonsense

It was inevitable, I suppose, that the putative hybrid shot in Arviat, Nunavut last week (see my post here) would initiate the global warming blame game.

Washington Post, 23 May 2016, Adam Popescu: “Love in the time of climate change: Grizzlies and polar bears are now mating

Here are the five points you need to know about polar bear hybridization, as there are several nonsense statements contained in this Washington Post article.

UPDATE 24 May 2016: References adding below regarding grizzly sightings south of Churchill on the west coast of Hudson Bay (H/T Doug Clark).

UPDATE 28 May 2016: See this 27 May 2016 follow-up post (Most polar bear hybrids said to exist have not been confirmed by DNA testing) for details on unconfirmed sightings or reports of hybrids.

Another alleged grizzly-polar bear hybrid shot but it’s not a sign of climate change

CBC News this morning (“Grolar or pizzly? Experts say rare grizzly-polar bear hybrid shot in Nunavut: Expert says interbreeding may be happening more frequently due to climate change“) suggests that a putative grizzly x polar bear hybrid bear shot outside Arviat in Western Hudson Bay is a sign of climate change, based on an interview with a black bear expert from Minnesota.

This bogus claim has been busted so many times it’s a wonder it still arises – even polar bear specialist Ian Stirling has said flat out that such hybrids are not due to climate change. On top of that, some of the details regarding this putative hybrid make me want to wait for confirmation from DNA testing before adding it to the roster of known hybrids.

Nunavut survivor describes what a polar bear attack is like

From NunatsiaqOnline yesterday, a detailed description of a polar bear attack that took place along Hudson Strait, within the Davis Strait polar bear subpopulation.

Kootoo Shaw was wearing nothing but long johns and a T-shirt when a 400-pound polar bear dragged him by his toes along the tundra towards the ocean outside Kimmirut in September 2003.

Shaw, 46, was working as a guide on a sport-hunting trip when the attack occurred in the early morning. Continue reading

BBC perspective on Arviat polar bears – those not included in the last mark-recapture study

In a polite but misleading article today in a BBC magazine (The polar bears are coming to town) about the relationship of polar bears and Inuit in Arviat, Western Hudson Bay, there is no mention of the on-going feud between Nunavut Inuit and Canadian polar bear scientists regarding invasive research.

Nor is there a mention of the fact that according to the most recent research, there has been no trend in sea ice conditions since 2001.

Well-fed polar bears onshore at height of summer easily deterred by noise, CBC reports

From the CBC this morning, we have the report of a female polar bear and her cub paying a visit to an Nunavut campsite near Chesterfield Inlet in northwestern Hudson Bay, which is technically within the boundary of the Foxe Basin polar bear subpopulation.

These are not the desperate bear victims of global warming we have been warned about by polar bear specialists but well-fed curious ursids not averse to an easy meal if there’s one to be had. Such bears are easily deterred by a loud noise. Note this was the second visit by polar bears this Nunavut family had experienced at this location within a three-week period – two other bears had stopped by earlier. Note that ice in this region of Hudson Bay broke up earlier than usual this year yet these bears seem to be in fine condition and can expect the first fall ice of the season (freeze-up) to appear in their neighbourhood, see maps below.

Heavy ice in Hudson Bay derails ArcticNet global warming research plans: irony bites

Heavy ice in Hudson Bay derails CCGS Amundsen’s research plans” – just in from the CBC (22 July 2015, via Twitchy). Worst ice in 20 years.

[original caption for the above photo: “The CCGS Pierre Radisson escorts the oil tanker Havelstern to Iqaluit July 17. Tough ice conditions in area have delayed this summer’s annual resupply, and have now derailed the CCGS Amundsen from its carefully planned summer research program.”]

Worst ice conditions in 20 years force change of plans to icebreaker research program

That would be 1992 they’re talking about, the cold year that everyone blamed on the eruption of Mt. Pinatubo. Unfortunately, there are no good detailed ice maps from 1992 (see previous post here). What’s the excuse this year?

CCGS Amundsen is an icebreaker that is usually released from duty to serve as an Arctic research vessel in the summer. And who’s on board? GEOTRACES 2015 Arctic Expedition out of the University of British Columbia with a plan to study (in part) global warming caused “ocean acidification.” Their short blog post shows a map without ice and not a hint they see the irony of the situation.

Here’s the ice they’re talking about (from the Canadian Ice Service), with the communities mentioned in the study marked:

Polar bear doom and gloom from USGS vs. biologist Mitch Taylor’s reasoned thoughts

A few days ago polar bear biologist Mitch Taylor and Nunavut’s Gabriel Niryungaluk talked to Toronto radio host Roy Green about the recent USGS dire model predictions for the future of polar bears.
