ON HUDSON BAY (AP) — Searching for polar bears where the Churchill River dumps into Canada’s massive Hudson Bay, biologist Geoff York scans a region that’s on a low fat, low ice diet because ofAnd it’s getting lower on polar bears.

There are now about 600 polar bears in the Western Hudson Bay, one of the most threatened of the 20 populations of the white beasts. That’s about half the number of 40 years ago, says York, senior director of research and policy at Polar Bears International. His latest study, with a team of scientists from various fields, shows that if the world doesn’t cut back more on emissions of heat-trapping gases “we could lose this population entirely by the end of the century,” he says.Water from the Churchill River, left, drains into the Hudson Bay, top right, Thursday, Aug. 8, 2024, in Churchill, Canada.

More than polar bears are threatened in this changing gateway to the Arctic, where warmer waters melt sea ice earlier in the year and the open ocean lingers longer. For what grows, lives and especially eats in this region, it’s like a house’s foundation shifting. “The whole marine ecosystem is tied to the seasonality of that sea ice cover,” University of Manitoba sea ice scientist Julienne Stroeve said.

When the sea ice melts earlier it warms the overall water temperature and it changes algae that blooms, which changes the plankton that feed on the algae, which changes the fish, all the way up the food web to beluga whales, seals and polar bears, scientists say.on Saturday followed their civic duty by eating what’s become known as a democracy sausage, a cultural tradition as Aussie as koalas and Vegemite, and for some just as important as casting their vote.

The grilled sausage wrapped in a slice of white bread and often topped with onions and ketchup is a regular fixture of Antipodean public life. But when offered at polling places on, the humble treat is elevated to a democracy sausage — a national, if light-heated, symbol for electoral participation.

Or, as a website tracking real-time, crowd-sourced democracy sausage locations on polling day notes: “It’s practically part of the Australian Constitution.”But the tradition is far from political. Cooking and selling the snacks outside polling places is the most lucrative fundraising event of the year for many school and community groups.
