U.S. Geological Survey scientists do not hold out much hope that carbon dioxide can be turned around in time to help the polar bears...
Report: Most polar bears to die out by 2050 Two-thirds of the world’s polar bears will be killed off by 2050 — and the entire population gone from Alaska — because of thinning sea ice from global warming in the Arctic, U.S. government scientists forecast Friday.
Only in the northern Canadian Arctic islands and the west coast of Greenland are any of the world’s 16,000 polar bears expected to survive through the end of the century, said the U.S. Geological Survey, which is the scientific arm of the Interior Department.
USGS projects that polar bears during the next half-century will disappear along the north coasts of Alaska and Russia and lose 42 percent of the Arctic range they need to live in during summer in the Polar Basin when they hunt and breed. A polar bear’s life usually lasts about 30 years.

Do you know why we don't implement more aggressive rules about hunting Polar Bears? My understanding is that habitat declines have less impact (currently) than hunting, though from this it appears maybe the system won't sustain any bears at all in future.
Also this raises the big question -if we can't reverse CO2 to have much affect on pending GW problems like this, what are the smartest actions.
