Polar bears no longer on 'thin ice': researchers say polar bears could face brighter future
Date:12/21/2010

LI> Even under relatively stringent mitigation reductions in future greenhouse gas concentration, polar bears in two of the four eco-regions, constituting about 2/3 of all current polar bear numbers, will still incur at least reductions in numbers and distribution. However, the best future outcome for these populations would result from a combination of mitigation control of greenhouse gas concentration with best on-the-ground management practices to control hunting and human activities such as levels of shipping, oil and gas activities, etc.

  • There will still be significant uncertainty as to the future of polar bear populations from the combination of all sources of stressors from climate change, direct human disruption, and other biological factors.

    The team's study is significant. "It demonstrates for the first time thatand howa combination of greenhouse gas mitigation and control of adverse human activities in the Arctic can lead to a more promising future for polar bear populations and their sea ice habitat," says Marcot. "It also provides specific predictions of the future, couched in terms of probabilities of polar bear population response that decision-makers could use in risk management."
