Global warming seen as main threat to Arctic predators
Endangered Species Act protection for polar bears will remain in place following a U.S. Supreme Court decision late last week to reject an attempt by the fossil fuel industry to overturn the 2010 listing.
A federal recovery plan for endangered polar bears won’t halt the threat of climate change, but it could help dwindling populations of the great Arctic predators persist in the small patches of habitat that will remain after global warming melts most of the polar sea ice.
The plan, released Jan. 9, calls for reducing human-bear conflicts, collaboratively managing subsistence harvest, protecting denning habitat, and minimizing the risk of contamination from oil spills. Most of these actions are already underway, in partnership with Alaska Native communities, nonprofit groups, and industry representatives who participated in the plan’s creation. The plan also calls for increased monitoring and research. Continue reading “Feds finalize polar bear conservation plan”→
New study suggests land-based food sources may help polar bears stave off starvation as sea ice melts
FRISCO — Scientific discussions over the fate of polar bears in the global warming may heat up as a new study found that some of the Arctic predators may be able to survive by eating caribou and snow geese instead of eggs.
‘Polar bear conservation requires a global commitment to curb the release of greenhouse gases into the atmosphere …’
FRISCO — The only thing that will save polar bears in the long run is a big cut in global greenhouse gas emissions, federal biologists said last week as the rolled out a draft recovery plan for the Arctic predators.
‘Addressing sea ice loss will require global policy solutions …’
FRISCO — Loss of Arctic sea ice caused by increasing concentrations of greenhouse gases remains as the primary threat to polar bears, U.S. Geological Survey researchers said after updating their research models.
