Results from spring Norwegian fieldwork in the Svalbard region of the Barents Sea are in and they show that despite having to deal with the most extreme loss of summer sea ice in the Arctic, polar bears in this region continue to thrive.
Svalbard polar bear territory (managed by Norway) includes sea ice to the Russian boarder to the east as well as the area around the Svalbard archipelago: the map below is from Aars et al. 2017.
Observations were collected around Svalbard by a team lead by Jon Aars and Magnus Andersen of the Norwegian Polar Institute between March and May this year, and posted online 4 June 2019. Kudos to them for making their on-going observations and analysis available, in a timely manner for all to see.
Note that Svalbard is the western half of the ‘Barents Sea’ polar bear subpopulation: in recent years, most of the region’s polar bears have been living around Franz Josef Land in the eastern (Russian) sector where Norwegian researchers are not permitted to work.

Here we are at the middle of June, when most polar bears are pretty much done with hunting seals for the season. And despite hand-wringing from some quarters, sea ice extent is down only marginally from average at this time of year and certainly not enough to impact polar bear survival.
Given the large expanse of open water in the Southern Beaufort so early in the season, one resident pessimist insists those polar bears are “challenged” by the lack of ice. If he is right, there should be reports of dozens upon dozens of skinny and dying bears along the coast of Alaska this summer. If not, he will pretend he never suggested any such thing.
So far, despite the early loss of ice in some regions, there have been no reports of polar bears ashore unusually early. Hudson Bay still has lots of thick first year ice, so despite the overall reduced Arctic ice coverage, none of the three Hudson Bay polar bear populations are facing the earlier-than-usual sea ice breakup this year as we keep being promised will show up. In fact, there hasn’t been a significantly early breakup in Western Hudson Bay since 2010 (see previous posts here and here).

Abundant ice in Svalbard, East Greenland and the Labrador Sea is excellent news for the spring feeding season ahead because this is when bears truly need the presence of ice for hunting and mating. As far as I can tell, sea ice has not reached Bear Island, Norway at this time of year since 2010 but this year ice moved down to the island on 3 March and has been there ever since. This may mean we’ll be getting reports of polar bear sightings from the meteorological station there, so stay tuned.
Sea ice extent as of 11 March 2019, from NSIDC Masie:
Much of the ice that was blown out of the Bering Sea early in the month has returned and ice in the Gulf of St. Lawrence on the East Coast of Canada is the highest its been in years, threatening to impede ferry traffic between Nova Scotia and Newfoundland, as it did in 2015 and again in 2017. The fishing season off Newfoundland might also be delayed by the heavy ice, as it was in 2017.

The state of emergency in Belushya Guba on Novaya Zemlya is over, according to a report yesterday from the Russian news agency TASS (18 February 2019), as no bears had been spotted over the previous 24 hours.

Since early December, a group of 52 polar bears have terrorized the Russian village of Belushaya Guba on southern Novaya Zemlya. The aggressiveness of some of the bears, their boldness in entering local buildings and fearlessness in the face of the usual deterrents has caused the local government to call a state of emergency to help the town residents. Global warming is blamed for the problem but as is so often the case, that claim does not stand up to scrutiny.

Belushaya Guba is located on the southwest coast of Novaya Zemlya in the eastern Barents Sea. It is a town of mostly military personnel and their families:
The predictable claims that this situation is due to global warming are confounded by the fact that the region has not had abundant sea ice by December in more than 30 years, yet this is the first time the town has had such a problem with polar bears. Polar bears in winter can be very dangerous, as they are often lean and desperately hungry. [except these ones are not, see update below]
UPDATE 11 February 2019: The international media have gone mad for this story and some photos are now available. Best series of photos and video is at The Daily Mail, UK (11 Feb 2019: State of emergency is declared after more than 50 polar bears invade Russian town and ‘chase terrified residents’). No new information is available on the story itself but plenty of hyperbole has been added. The photos show how fat and healthy these so-called ‘desperate’ bears are, which makes the claims that global warming is to blame for the crisis even more ludicrous (see the ice charts below). So far, the most over-the-top take on this goes to the Washington Post (11 Feb 2019: A ‘mass invasion’ of polar bears is terrorizing an island town. Climate change is to blame): they went to the most trouble to make the link to climate change and bring up the vilified ‘starving polar bear’ video that National Geographic was forced to apologize for last August and the debunked 2007 prediction that 2/3 of the world’s bears would be gone by 2050 (Crockford 2017). The Guardian‘s effort is weak by comparison, as is CNN‘s. The news outlet (not a blog) Daily Caller has some quotes from this page. Competition amongst bears for scarce natural resources in winter makes dump sites and stored food available around Arctic communities all the more attractive. When polar bear numbers are high, as they are now, this competition can get fierce. It’s no wonder the bears don’t want to leave.

January is the first month of the Arctic winter, the season when most polar bears really struggle to find enough to eat.
Here is what the sea ice looked like around the Arctic at the end of this month.
Compare to last year:

“…despite the loss of good denning areas and a shrinking habitat for hunting, Svalbard’s bears seem to be doing fine.…The sea ice season is now several months shorter, and the ice edge typically lies several degrees further north than what was normal 20-40 years ago….Polar bears can survive long periods without food, provided they have accumulated a good fat reserve during the few months in spring and summer when sea ice is present, and seals are abundant.” [Jon Aars, Norwegian Polar Institute, 2018]
Jon Aars from the Norwegian Polar Institute has written an update on the status of Svalbard polar bears for the general public (The Barents Observer, 8 January 2019, republished from a story published by The Fram Centre in their newsletter: Population changes in polar bears: protected, but quickly losing habitat).
