Shrinking sea ice may be to blame for recent polar bear cannibalism incidents in Canada. Eight cases of adult polar bears eating bear cubs and other bears near Churchill, Manitoba, have been reported. Four of the cases were reported to Environment Canada and four to Manitoba Conservation.
While adult male polar bears, Ursus maritimus, have been known to kill and cannibalize cubs, most cases occur in the spring when the male can impregnate the female. Due to the timing of the incidents, some believe hunger may be the reason for this year’s incidents.
By early November, the ice in Canada’s Hudson Bay is normally solid enough for polar bears. But with December rapidly approaching, the ice is just not solid enough. Polar bears depend on annual sea ice as a platform for hunting, a place to raise young and as a habitat for mating. As the ice shrinks, starving polar bears are not only resorting to cannibalism, but are also drowning. Four polar bears drowned in 2004, trying to swim between ice and shore.
According to the US Geological Survey (USGS) and the Canadian Wildlife Service (CWS), the impact of climate change on the species in western Hudson Bay, has resulted in a 22 percent reduction in the population. 1,194 polar bears lived in western Hudson Bay in 1987. By 2004, only 935 remained.
Listed as Threatened on the IUCN Red List, oil spills, pollution and hunting threaten the species. But according to some, climate change is the most serious threat to the polar bear population.

“25 Nov 2009 … Look at the picture of that polar bear. He’s running out of ice habitat to live on because of global warming. That was checked out even with the Inuit people, they tell us there is an over population of Polar Bears as shown on TV news! of all places
If you own any shares in alternative energy companies I should start dumping them NOW. The conspiracy behind the Anthropogenic Global Warming myth (aka AGW; aka ManBearPig) has been suddenly, brutally and quite deliciously exposed after a hacker broke into the computers at the University of East Anglia’s Climate Research Unit (aka CRU) and released 61 megabytes of confidential files onto the internet. (Hat tip: Watts Up With That)
When you read some of those files – including 1079 emails and 72 documents – you realise just why the boffins at CRU might have preferred to keep them confidential. As Andrew Bolt puts it, this scandal could well be “the greatest in modern science”. These alleged emails – supposedly exchanged by some of the most prominent scientists pushing AGW theory .The Global Climate Change, Carbon Emmissions, Carbon Tax system is a comolete Fraud!

These claims are just embarrassing the cause. I keep waiting to see the claim that baldness is caused by Global Warming. If you claim to speak as a source of knowledge…please do some research first.
Kivalliqu Inuit Association president Jose Kusugak said: ‘It makes the south – southern people – look so ignorant. ‘A male polar bear eating a cub becomes a big story and they try to marry it with climate change and so on, it becomes absurd when
it’s a normal, normal occurrence.’
