The Weather Network – On the ground in Churchill: Polar bears fight for survival as ice disappears

Sunday, February twenty seventh 2022, 9:00 am – Polar bears are hardy creatures—they will quick for upward of 180 days and swim a whole lot of miles with no break—however consensus amongst scientists is that the animals gained’t be capable of discover new meals sources as soon as they will not hunt seals.

On the bay this fall morning, there’s a wind-carved rim of ice and a gathering of floes. One male polar bear, bony after a season with out seal blubber, struggles alongside the slushy edge, haunches soaked, practically slipping into the ocean.

We’re on Gordon Level, in northern Manitoba, the place Hudson Bay widens into its northwest crescent. Polar winds make it colder than at comparable latitudes, and the shallow waters of the bay freeze early. Having handed the summer time months within the subarctic wild of Wapusk Nationwide Park to the south, polar bears now congregate right here, ready for the ice to come back in.

The air is harsh, dry, frigid. We huddle on the deck of Tundra Buggy One, a big-wheeled bus retrofitted for travelling over frozen floor and viewing polar bears. Geoff York, senior director of conservation for Polar Bears International (PBI), makes use of Buggy One as a roving analysis station. It’s geared up with GPS, Wi-Fi and polar bear cams that beam stay footage to lecture rooms all over the world.

PBI screens polar bears throughout the Arctic partly to find out the impacts of local weather change on the habits and bodily situation of the animals in addition to inhabitants traits. One program has tracked polar bears outfitted with GPS ear tags or collars that transmit places to researchers to realize perception into the animals’ actions. York says, “Our understanding of polar bear biology, ecology and habits is important for long-term conservation and may inform on-the-ground efforts like human-bear battle administration.”

From the deck of Buggy One, there are a number of bears in sight, largely massive males. Invisible in an Arctic blizzard, their double-layer coats, not stark white however golden like sheep’s wool, stand out faintly within the distance on a transparent day comparable to this. They tussle playfully or sleep among the many twiggy willow stands on shore. One immense bear sits humanlike on its haunches, blades of grass in its tooth. Others wander the ice rim with a lazy gait that belies their deadly quickness.

York has warned us of the risk the bears pose. “The massive bears have doubtless scared off the household teams,” York says, explaining that at this determined time of yr, when adults are near-starving earlier than the sealing season, males usually tend to cannibalize cubs and assault people. Regardless of the hazards, York has centered his 22-year profession on stewardship of the polar bear. He and his spouse, Rachel, are planning to maneuver from Montana to Manitoba so he will be near them.

The polar bear has change into maybe the pre-eminent image of the implications of local weather change as a result of it wants sea ice to outlive. From November, when the ice fastens to shore, to Might, when it breaks up, the ice is polar bear territory throughout the Arctic. The bears sleep on the ice at night time, and pregnant females may even hibernate there through the winter. Males and non-pregnant females keep energetic via the winter days, and the ice is their searching floor. Laying ambush behind a stress ridge of ice fragments, the bears stalk seals. “On the ice, they’re gradual,” York says of the seals. “The bears are explosive as they run them down.”

There are between 16,000 and 31,000 polar bears on the earth as we speak, congregating in 19 populations throughout the Arctic. In some areas the place the bears have been closely impacted by searching, bans helped their numbers resurge. However the shrinking of their Arctic habitat is making the species increasingly fragile worldwide. In Greenland and Norway, the World Wildlife Basis lists polar bears as weak. In Russia, they’re uncommon or recovering, relying on the situation, and in Alaska (the one place in america the place they’re discovered), polar bears are threatened. In Canada, the place 60 to 80 p.c of polar bears stay, they’re a species of particular concern, a click on of the dial beneath threatened or endangered.

The inhabitants within the Western Hudson is especially in danger, having fallen from 1,200 polar bears within the Nineties to about 800 as we speak. Local weather change has shrunk the expanse of sea ice that when unfold from the North Pole to southern Hudson Bay. In 2020, the ice space was the second smallest since measuring started within the Seventies, and it’s thinner than ever.

Throughout our go to in early November, the bay’s newly shaped ice, having warmed, started to shatter like a teacup. Days later, a south wind pushed all of it ashore. “We want north winds bringing cool air and some days at minus 20 Celsius,” York mentioned, a be aware of concern in his voice.

Polar bears are hardy creatures—they will quick for upward of 180 days and swim a whole lot of miles with no break—however consensus amongst scientists is the animals gained’t be capable of discover new meals sources as soon as they will not hunt seals. If a warming local weather shrinks sea ice at projected charges, most polar bear populations will probably be too nutrient-starved to breed by the top of the twenty first century.

In the meantime, shrinking sea ice appears to be main bears to wander into human settlements from Russia to Norway, Greenland to Alaska. Issues ensue. In Alaska, an offshoot of a Russian polar bear patrol program trains communities to make use of instruments like bear spray, flashlights, air horns and rubber bullets to discourage bears and shield themselves, whereas Canada’s Nunavut Territory administers related efforts via a polar bear battle supervisor primarily based in Igloolik. Right here in northern Manitoba, a comparable program operates in Churchill, “The Polar Bear Capital of the World.”

Churchill is a city totally of the north. Its gridded blocks of aluminum-sided homes sit between miles of cratered tundra and the icy mouth of the Churchill River. This chilly flank of Hudson Bay was as soon as a gathering place for Inuit hunters and the Cree and Dene First Nations. In the present day, about three-quarters of Churchill’s virtually 900 residents determine as Indigenous. The city boasts one of many solely film theaters inside a thousand miles, in addition to entry to Canada’s solely deep-water port within the Arctic.

Because the local weather warms, extra bears wander into Churchill to scavenge—or moon round in backyards, or chew the seat off a snowmobile. Mayor Michael Spence, a member of the Cree First Nation, says bear sightings have been a novelty when he was a boy within the early Sixties—he remembers taking part in in a recreation of street hockey that was interrupted by a mom and two cubs—however as we speak they’re extra widespread.

On Halloween 2013, a 30-year-old girl named Erin Greene, who had moved to Churchill from Montreal the earlier yr, was leaving a celebration with buddies when she regarded over her shoulder. “There’s this bear that’s already full-speed working at us,” Greene says. Whereas her buddies ran for assist, the bear started carrying her off. “I noticed that this was a combat I couldn’t win by myself and simply accepted that that is the best way I used to be going to die,” she says.

Simply in time, a neighbor appeared, hanging the bear’s head with a shovel. The bear dropped her and she or he was airlifted to the hospital to deal with her life-threatening accidents. Regardless of the terrifying ordeal Greene suffered, and the scars and occasional pains she nonetheless bears, she returned to Churchill. The explanation, she says, is a high quality specific to the north. “The chilly burns your face, the sky is gorgeous, the animals might be round each nook. It’s so actual, it’s so uncooked,” she says. She feels a distinct connection to polar bears now—“a distinct understanding.” Her medical payments added as much as hundreds of {dollars}, however the area people paid all of them.

About 10,000 folks arrive in Churchill each fall to see polar bears. Guests collect on the Tundra Buggy Lodge, a analysis and tourism outpost constructed from conjoined buggies. It’s additionally residence to PBI’s latest expertise, the SpotterRF—a compact surveillance gadget designed to take care of threats like drone assaults. Right here, it’s used to identify polar bears.

In essentially the most primary sense, the SpotterRF is a movement detector—very similar to these used to show porch lights on. As bears transfer on the tundra, they set off the sensors. Their places pulsate on a digital map, which will be analyzed by York and different scientists. The software program performs effectively at night time and in snowstorms, and should in the future function an early warning system for Churchill.

To maintain us protected, Buggy One has backed right into a fenced platform on the Tundra Buggy Lodge, like a spaceship docking into port. Contained in the Lodge, the SpotterRF radar beeps to sign the method of a trio of bears. One among them, precocious and curious, toddles close to sufficient that we may poke a finger via the bars and contact its nostril. York has informed us about “bear jail,” an enclosure that captures bears on the town to allow them to be relocated. However right here, he says with an approving smile, “we’re those within the cage.”

The subsequent afternoon, again out on the tundra, we watch skinny bears tempo the shore. Some hunker down in kelp beds, chewing on the seaweed. An enormous male stomps the snow with each entrance paws. One other lies encircled in a snowdrift.

When the tide is available in, daylight escapes the patchy financial institution of clouds and brightens the mosaic of ice floes on the bay. From the willows, a mom approaches with a cub, their tempo slowing as they absorb two massive bears skulking the place the ice meets the water. The mom appears previous them, and from the deck of the car we comply with her gaze, out to the bay’s churn. York hopes the ice will probably be strong quickly. “In the event that they go too early, and the ice breaks up, they’d have an extended swim again to shore.”
