Tipping point

Biologists predict Manitoba’s polar bears will disappear within thirty years.

The increasing length of the ice-free season on Hudson Bay will soon reach a tipping point where 20 to 30 per cent of Manitoba’s polar bears will begin dying off every year, according to a mathematical analysis released by Stirling’s colleague, University of Alberta biologist Andrew Derocher, who has studied polar bears for 28 years.

The predictions mean the province that calls itself the polar bear capital of the world may no longer be able to count the iconic Arctic animal as a resident species within a generation.
