Scientists say shrinking Arctic sea ice may be forcing some polar bears into cannibalizing young cubs.

Bears lose up to 30 per cent of their body mass in summer and autumn waiting on land for the sea ice to refreeze so they can use it as a platform to hunt seals.

They used to be able to get out on the ice of Hudson Bay by early November, but freeze-up is now weeks later. This year, as December approaches, it still isn't solid enough for the bears.

So far this fall, tour operators and scientists have reported at least four and up to eight cases of mature males eating cubs and other bears in the population around Churchill, Man. Four cases were reported to Manitoba Conservation and four to Environment Canada.
