Winnipeg zoo unashamedly frightens children about polar bear extinction, for a price

The Assiniboine Park Zoo in Winnipeg is selling Polar Bears International-style1 “save our sea ice” global warming propaganda to children, which it calls “messaging.”

“The centre is deliberately targeting children, fully aware that there is a magical connection between the cuddly, entertaining orphan cubs and young visitors.”

Labrador polar bears face a longer ice-free season than Hudson Bay bears, but do well

Funny thing is, the Davis Strait subpopulation may still be increasing despite a longer ice-free season than Western Hudson Bay. And bears in the south of that region – who spend the summer onshore in Labrador – have the longest ice-free season of all1 yet according to the latest survey they were even doing better than bears in northern Davis Strait.

That apparent paradox has an easy explanation – sea ice extent in late summer/early fall (length of the ice-free season) has much less of an impact on polar bear health and abundance than the state of the food supply in the spring. More seals in spring, polar bears do well; few seals in spring, polar bears starve.
