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.
FRISCO — Enacting more endangered species regulations isn’t enough to reduce global warming threats to ice-dependent marine mammals in the Arctic, scientists say.
In a new report published in the journal Conservation Biology, a research team called for better monitoring, increased cooperation and more study of how increasing human activity in the Arctic will affect ecosystems.
The report assesses the status of all circumpolar species and sub-populations of Arctic marine mammals, including seals, whales and polar bears and underscores the precarious state of those mammals.
