These trends spell danger for polar bears.
In 2020, a study published in the journal Nature which studied polar bear demographics between 1979-2016 suggested that the species could vanish within a century if greenhouse gas emissions remain high.
Today, there are thought to be around 26,000 polar bears on Earth, with surveys showing that the populations in Canada’s north are declining.
“It’s Hudson Bay, Baffin Bay, and the Davis Strait, which is mostly in northern Canada. Polar bears have historically had to leave the ice in these places because of their location. They’re now required to stay off the ice for a longer period owing to climate change.” Dr. Steven C. Amstrup, Chief Scientist at Polar Bears International, said this on CTV News.
