An IUCN report has estimated that between 22,000 and 31,000 polar bears in Arctic are increasingly vulnerable to extinction as their habitat shrinks. Polar bear population will lower by more than 30% by mid century following the thawing of Arctic sea ice due to global warming. Climate change will threaten polar bear survival in the future as well. This study was based on updated counts and new projections of sea ice following a 2008 review.
