From Reuters:
Polar bear populations are likely to fall by more than 30 percent by around mid-century as global warming thaws Arctic sea ice, experts said on Thursday in the most detailed review of the predators to date.
The report, by the IUCN (International Union for Conservation of Nature), estimated there are between 22,000 and 31,000 polar bears in the Arctic and said they will be increasingly vulnerable as their habitat shrinks.
