Polar bear population in Western Hudson Bay unlikely to survive climate disruption

Here are the key notes and numbers taken from the paper:

– In Western Hudson Bay, we predict that climate warming-induced litter size declines will jeopardize population viability.
– About 28% of pregnant females failed to reproduce for energetic reasons during the early 1990s, but 40-73% could fail if spring sea ice break-up occurs one month earlier than during the 1990s, and 55-100% if break-up occurs two months earlier. Simultaneously, mean litter size would decrease by 22-67% and 44-100%, respectively.
