How are polar bears doing 15 years after the IUCN declared them ‘vulnerable’ to extinction?

The beginning of this month was the 15th anniversary of the day the IUCN declared polar bears ‘vulnerable’ to extinction because of climate change, the first time such a designation had ever been made. It was based on the opinion of polar bear specialists who examined the vague information available at the time and decided that in 45 years the bears might be in serious trouble. This decision changed the way the IUCN assessed species risk and led to mass confusion for the general public, who falsely assumed polar bear numbers had already declined by a huge amount.

Death of prominent Canadian polar bear biologist a tragic loss to science

Markus Dyck, a renowned Canadian polar bear biologist, died in a helicopter crash near Resolute Bay, Nunavut, along with two crew members on Sunday 25 April 2021. Dyck and the crew were beginning this year’s survey of the Lancaster Sound polar bear subpopulation (Crockford 2021), which hasn’t had a population count since 1997.

From the initial CBC News report on Monday 26 April:

Three people are dead after a helicopter crash near Resolute Bay, Nunavut, during a trip to survey the Lancaster Sound polar bear population, the premier says.

It happened near Griffith Island and involved a Great Slave Helicopters AS350-B2.

A news release on Monday morning from Yellowknife-based Great Slave Helicopters said there were two flight crew and one wildlife biologist on board. No one survived, the company says.

Crash site of helicopter was near Griffith Island, near Resolute in the Central Canadian Arctic.

The wildlife biologist was identified on Wednesday as Igloolik resident Markus Dyck, CBC News reported yesterday:

Dyck was surveying bear populations in Lancaster Sound for the Nunavut government on the day the helicopter crashed. Two other air crew also died.

Lemelin said Dyck was outspoken in his advocacy for community-based polar bear management.

“Markus was one of those individuals that fell in love with the bears and highly respected them and dedicated his life to them,” he said.

Lemelin said Dyck told him two weeks ago that he was heading out for field work.

“He was working for Nunavut and working with incorporating traditional knowledge and scientific knowledge and examining all types of research and doing those very important sample counts that are necessary.”

The Igloolik-based scientist challenged environmental groups that said the bears were disappearing. He also championed including traditional knowledge in research, Lemelin said.

“What he was concerned with is the ability of Inuit people and Cree people to live with the polar bears to continue traditional harvesting practices and to manage polar bears sustainably and respectfully, in the long-term,” Lemelin said.

The accident is a strong reminder of the dangers of Arctic research, which almost always now involve the use of fossil fuel powered helicopters (Nunatsiaq News 27 April 2021):

As a current member of the international Polar Bear Specialist Group, which looks at polar bear population management worldwide, Dyck remained an “outspoken” force for community-based polar bear management in the highly political world of polar bear research, Lemelin said.

Dyck, who held a master’s degree from the University of Manitoba, was certified wildlife biologist with the Wildlife Society, according to his LinkedIn profile.

Before working at the GN, he was senior instructor with the Environmental Technology Program at Nunavut Arctic College in Iqaluit.

Polar bear surveys — and the sometimes dangerous conditions that come with them — were nothing new to Dyck.

In 2014, he told Nunatsiaq News that the M’Clintock polar bear survey’s first year was plagued by fog in an area thick with heavy ice.

“Blizzards, we had fog — we had to sleep in the helicopter, on the sea ice one night, because we couldn’t fly anywhere,” Dyck said.

Mark Mallory, a seabird biologist who knew Dyck well, said working in helicopters in the High Arctic is “dangerous stuff.”

“Working in helicopters in this time of year when things are changing, and you’re starting to get moisture in the air, and the wind is picking up, and you’re out in that interchange between the land … that’s a terrible time to be working there,” Mallory said.

“A lot of people think when you are out doing surveys, that it looks so fun. You’re out in an aircraft counting animals. But it’s actually pretty dangerous. There’s no way around it: when you do this work in harsh conditions, you take risks.” Mallory and Lemelin said Sunday’s crash brought back memories of other helicopter crashes which killed researchers in the High Arctic: in 2000, when two wildlife biologists died near Resolute Bay, and in 2013, when a pilot, scientist and CCGS Amundsen’s commanding officer died near Banks Island

Earth Day 2021: celebrate abundant sea ice habitat for polar bear feeding and mating

Late April is the height of the most important polar bear feeding and mating season and there is abundant sea ice habitat across the Arctic for doing both.

Sea ice charts below. Compare to 2018 conditions here; 2015 here; and 2014 here. Sea ice maximum this year was apparently “uneventful” according to the folks at the NSDIC because it didn’t even come close to setting a new low record.

Less than usual ice conditions off Labrador have meant very few polar bear sightings

I’ve been wondering ever since last year why reports of polar bears onshore in Labrador especially and also the north coast of Newfoundland, have been virtually non-existent. This year there has been little ice off Newfoundland except for the Northern Peninsula but relatively abundant ice off the south coast of Labrador.

Yesterday, Canadian Ranger and polar bear guard Jefferey Keefe of Black Tickle (which is on an island off the Labrador coast) said on a CBC radio interview (13 April 2021) that while in 2019 they had 72 sightings around the community over the season, last year they had 7 and so far this year they have had only 2 sets of tracks – but no actual sightings of bears. He estimated the average number of sightings per year is about 20, and that he had talked to his colleagues in Makkovik (north of Rigolet on the map below) and their experience is similar. It appears that numbers are down throughout southern Labrador, although one bear was seen in Charlottetown last week (south of Black Tickle).

Keefe said that the sea has been very rough around the island this year, effectively breaking up the young sea ice almost as soon as it forms. They have no ice in their harbour right now, which is unusual. He thinks this lack of nearshore ice is keeping the bears further out on the pack ice: the bears are still out there but just taking different routes this year. Given the current ice conditions locally, he’s not really expecting any more visits this season.

Below is a detailed ice chart of the region from this year: Black Tickle is south of Cartwright, which is marked on the chart.

In 2019, I kept track of published polar bear sightings in Labrador, not all of which were in Black Tickle. I’m pretty sure I didn’t miss any (Crockford 2020), but there was nowhere near 72 reports overall, let alone 72 just in Black Tickle. See here (mid-Feb); here (late Feb); here (mid-April); here (late May).

However, I was also pretty sure that every single sighting wasn’t making the news, which this information confirms. A total of 72 sightings in 2019 in Black Tickle alone is impressive! In Newfoundland, there were an impressive number of sightings in 2017.

The ice came early to Labrador in 2019 and continued to be be relatively heavy throughout the spring. There was lighter ice in 2020 but not as late and light as this year. From the comments of Sgt. Keefe, it seems the wind and sea conditions very close to shore have had more of an impact on potential polar bear visits in southern Labrador than the ice conditions well offshore. Although a population collapse would also explain the dramatic decline in sightings, there is no evidence I’ve heard about that Davis Strait numbers are way down, as some have predicted.

Listen to the whole thing at 13:30-18:00 on the tape.

Polar bear problems onshore in Svalbard before prime feeding season

At the end of March there were two polar bear incidents on the same day in Svalbard, where one bear trashed a holiday cabin. Think a door or a window can keep out a polar bear? Think again!

Choose verifiable facts over emotional narratives on polar bear conservation

Polar bears continue to be described as ‘canaries in the coal mine’ for the effects of human-caused climate change, but the evidence shows they are far from being a highly-sensitive indicator species.” Susan Crockford, 24 February 2021

You’ll find the evidence I allude to above – backed up by references to the peer-reviewed literature – in my many publications (Crockford 2015; 2017; 2019, 2020, 2021). My open-access research paper from 2017 has been downloaded more than 6,000 times and despite this being an online forum for legitimate scientific critique, none has been offered. My comprehensive polar bear science book released just two years ago (see below) has a 4.7/5.0 star rating on Amazon, with 132 reviews so far.

For recent blog post examples of the evidence that polar bears are thriving despite profound summer sea ice loss, see this discussion about the many contradictions that exist for claims that sea ice declines have caused harm to polar bear health and survival and this review of the evidence that less summer sea ice has meant more food for polar bears.

For those who haven’t seen it, I’ve copied below the preface from The Polar Bear Catastrophe That Never Happened. This book is an antidote to the emotional blackmail coming at the public from all sides by journalists, polar bear specialists, and elite influencers like David Attenborough.

Polar bears are an environmental success story: short video from ICSC Canada

From Tom Harris at ICSC Canada: In ‘State of the Polar Bear Report 2020’, zoologist Dr. Susan Crockford writes, “in 2020, even though summer sea ice declined to the second lowest levels since 1979, there were no reports of widespread starvation of bears, acts of cannibalism, or drowning deaths that might suggest bears were having trouble surviving the ice-free season.

Polar bears are thriving: an ICSC Canada short video

From Tom Harris at ICSC Canada: Polar bears are nowhere near as sensitive to declining sea ice than originally thought. In fact, their population is now three times higher than in the 1960s. 17 March 2021 [1:28]

 

Will low sea ice threaten harp seals & polar bears on Canada’s East Coast this year?

In early February this year, sea ice was much lower than usual along the Labrador coast and virtually non-existent in the Gulf of St. Lawrence, which are two important pupping habitats for North Atlantic harp seals. The picture would have been very bleak for harp seal pups and the Davis Strait polar bears that depend on them for food if ice hadn’t expanded and thickened by early March – but it did. Past experience suggests that harp seals that usually whelp in the Gulf of St. Lawrence, where ice is still well below average this year, will move to ice off Southern Labrador (‘the Front’) to have their pups.

Polar bear attack in Svalbard: victim survives, polar bear does not

A man was attacked from behind this morning by a small male polar bear on the east coast of Svalbard, Norway, where there is abundant sea ice. His companion shot the bear and the victim escaped with minor head injuries. Most bears are very hungry at this time of year because the seal pupping season has not yet begun.

Young bears are extremely dangerous and the most likely to attack people (Crockford 2019; Wilder et al. 2017): a three year old male fatally attacked a camper in August 2020 just outside Longyearbyen, Svalbard, an incident unfairly blamed on lack of sea ice (Crockford 2021).

UPDATE 3 March 2021: Results of an autopsy conducted on the polar bear killed yesterday revealed it was a 6 year old male that weighed only 231 kg, which is less than usual for an adult bear later in the season but likely typical for a relatively young bear at the end of winter before seal pups are born. See quote from a Norwegian polar bear specialist below [my bold]:

Jon Aars, an institute researcher who has spent many years studying bears in Svalbard, told Svalbardposten the vast majority of bears ages six to 15 will weigh between 350 and 450 kilograms in April, when the spring hunting season is typically at its peak.

“It may have been aggressive because it was thin,” he said. “It is likely. The thinner they are, the greater the chance that they are dangerous. He is at an age where he is not frequently considered as a problem bear – it is mostly among the younger or the very old who have problems.”
