Late Hudson Bay ice imperils polar bears

Late Hudson Bay ice imperils polar bears 18 Nov 2010 Hundreds of polar bears in northeastern Manitoba may face an increased risk of starvation due to delayed ice formation along the western coast of Hudson Bay, conservationists say. Higher-than-normal temperatures have prevented ice from forming in the region, putting it three to four weeks behind schedule, according to the Canadian Ice Service, a division of Environment Canada. As a result, minimum ice cover there is the lowest since 1971, CIS forecaster Luc Desjardins said.
