A photo of a mass walrus haulout at Point Lay, Alaska taken a few days ago from a distance show thousands of animals. But no one’s counting because apparently, no one’s interested.
The picture on the left (above, courtesy Alaska Dispatch News) was taken 23 August by global warming activist photographer Gary Braasch, the day after a news report appeared about the US Fish & Wildlife Service and aviation authorities asking the media to approach USFWS about walrus photos and information that gave no hint that a large haulout of walruses was already in place (22 August 2015, “Federal agencies, Point Lay seek to minimize walrus disturbances” ):
“Federal agencies are stepping in to shield a North Slope village from the possibility of a deluge of international attention should a large walrus haulout develop nearby, as it has in years past — agreeing to act as an information clearinghouse on behalf of the Native Village of Point Lay.” [my bold]
Here is what the global warming activist site that published the pictures says about the haulout:
“Thousands of Pacific walrus are coming ashore near Point Lay, NW Arctic coast of Alaska. The huge sea mammals and young began coming up on this barrier island along Kasegaluk Lagoon about August 20, according to local natives. This is one of the earliest known summer haul outs of the walrus along the Alaska coast of the Chukchi Sea, according to wildlife biologists.” [my bold]
They say “thousands.” But the photos taken, reproduced in the Alaska Dispatch News story I read, were taken from a greater distance than the famous photo of ~35,000 animals released by government officials last year and looks like the total could be as large, or larger, than the 2014 haulout.
Said a Washington Post story (27 August 2015):
“The U.S. Fish and Wildlife Service confirmed to the Post Wednesday evening that a mass of walruses had “hauled out,” or gathered on shore, near the remote community of Point Lay. The service did not estimate the number or provide images. But photojournalist Gary Braasch has posted dramatic photographs, taken during an Aug. 23 flyover, of what appear to be at least several thousand walruses crowding onto a barrier island.” [my bold]

Overall, the situation is better than many recent years – lower than average but higher than even 2012 and 2007, when all the polar bears didn’t die despite record-low extents for September. In several areas of the Eastern Arctic, sea ice levels continue to run higher than average. There is plenty of ice in the Arctic Basin for polar bears spending the summer under the midnight sun.
According to NSIDC MASIE (see map above):
2007 at 25 August – 5.2 mkm2
2012 at 25 August – 4.9 mkm2
2015 at 25 August – 5.3 mkm2
Researchers in the Arctic Basin yesterday spotted a hugely fat pregnant polar bear female on broken ice over water about 2,500 meters deep. Some people seem to find this surprising but it’s what I discussed last week.

Now, not so much. Here is a 16- year old CBC TV special on Churchill polar bears – listen to Ian Stirling and reporter Eve Savory use the early breakup of sea ice on Hudson Bay in 1999 to hype the alarm about Western Hudson Bay polar bears. Watch Stirling in action darting and measuring bears and bemoaning the good old days of the 1980s, claiming the “bears are sending a signal from the ecosystem.”
Watch this archived copy of “The Shrinking Bears of Hudson Bay” and compare his claims to what has actually happened in the 16 years since then. It runs just over 15 minutes.
“Just as the ice is shrinking in Hudson Bay, so are its polar bears. Climate change has shortened the season for winter ice, a crucial period for the bears to feast on seals and build up their fat reserves. And so, over the 18 years that wildlife biologist Ian Stirling has been studying them, the polar bears have become skinnier and their offspring fewer. In this 1999 report for CBC-TV’s The National, Stirling says once their habitat is gone, there’s nowhere else the Hudson Bay polar bears can go.” [my bold – see notes below]

• Broadcast Date: Sept. 23, 1999
• Duration: 16:39
Stirling has continue to make these claims since 1999, yet no updated evidence has been provided. There is no plausible evidence that the decline of polar bear numbers in Western Hudson Bay was due to sea ice changes caused by human-caused global warming (Crockford 2015) or that continued declines in condition of bears or litter size have occurred. Note that the latest survey of Western Hudson Bay polar bears found no trend in either breakup or freeze-up dates since 2001 (Lunn et al. 2013) and that the population is now stable.

At this time of year, sea ice extent numbers are meaningless for polar bears. The extreme low September minimum of 2012 – when masses of polar bears didn’t die – showed rational people that this is true. Even the low 2007 summer extent, which hit earlier in the season than 2012, had little to no negative impact.
In late summer, bears outside the Canadian Archipelago either retreat to shore or stay on the sea ice as it retreats north into the Arctic Basin (see image below, click to enlarge). Most bears in the Archipelago have ice year round, so life doesn’t change much. This means that it does not matter to polar bears how much area the Arctic Basin ice covers in September – for their needs, 1.0 mkm2 would be plenty.
Still, Southern Hudson Bay polar bears had extended hunting opportunities in July this year (whether or not they hunted successfully) and for this date, Hudson Bay had more ice remaining than any year on record. Yes, more than even 1992 but only by a few percent. See charts and maps below.

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.

Since 1971, there has been no year when there was as much ice left on Hudson Bay as there is this year at August 13th, except 1992 – the year when Mt. Pinatubo seemingly affected Hudson Bay ice levels but not any other region in Eastern Canada or the Beaufort Sea. Odd, that – see the graphs below.
Doesn’t mean that much to polar bears, since they will mostly be fasting whether they are onshore for the summer or riding the ice – they primarily live off their fat this time of year. Still, the relative ice levels are interesting because it could impact freeze-up dates later this fall, which will influence the bears’ ability to hunt before the winter fast sets in.
