A new study finds no evidence of an irreversible tipping point in Arctic sea ice. Instead, significant reductions in greenhouse gas emissions can help save polar bears.
Dr. Steven C. Amstrup explains his use of four ice eco–regions to help estimate how each of the 19 polar bear populations are faring.
Scientists who study polar bears are frequently asked whether the great white bears can adapt to life without sea ice. Biologist Evan Richardson explains.
The polar bear population in the southern Beaufort Sea has declined by about 40% in recent years. Dr. Steven Amstrup, chief scientist at Polar Bears International, talks about what this means.
Dr. Steven Amstrup, PBI Senior Scientist, discusses whether there will be any polar bears left in 50 years.
