2050 A Grim Deadline.

Two-thirds of the world's polar bear population could be gone by midcentury if predictions of melting sea ice hold true, the U.S. Geological Survey reported on Friday.
The fate of polar bears could be even bleaker than that estimate, because sea ice in the Arctic might be vanishing faster than the available computer models predict, the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species.
"There is a definite link between changes in the sea ice and the welfare of polar bears," said Steve Amstrup, who led the research team. Arctic sea ice is already at an all-time low this year and is expected to retreat farther this month, according to the U.S. National Snow and Ice Data Center.
That means that polar bears -- some 16,000 of them -- will disappear by 2050 from parts of the Arctic where sea ice is melting most rapidly, along the north coasts of Alaska and Russia, researchers said in a telephone briefing.
Other polar bear populations could survive beyond that date but many of those could be gone by 2100, Amstrup said. By century's end, the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland.

sian... ppl in the world cant even be bothered abt global warming, then how to save polar bear?
-
awareness is the keyword. taking action is another.

hahaha.. knew this will happen some time later.. alps will also be gone by 2050 sia.. humans can't make it in time to save the polar bears or reverse the effect.. this is because we are already too late sia..Originally posted by oOprinceOo:Two-thirds of the world's polar bear population could be gone by midcentury if predictions of melting sea ice hold true, the U.S. Geological Survey reported on Friday.
