Ian Stirling Adjunct Professor, University of Alberta Expertise: Polar bears Misleading Climate Posted on: 2020-10-29 Sea ice loss due to climate change is the biggest threat to polar bear survival and has already led to declines in some polar bear subpopulations, contrary to “Climate Realism” video message Claim: “In 1950, there were around 10,000 polar bears globally. Today, polar bear populations are near 39,000. Polar bear populations are increasing dramatically as the planet has warmed.” Source: Climate Realism, Heartland Institute, Andy Singer, 2020-10-23 Correct Climate Posted on: 2020-07-27 The long-term survival of polar bears is threatened by loss of sea-ice due to global warming, new study confirms Claim: "Global warming is driving polar bears toward extinction" Source: The New York Times, Henry Fountain, 2020-07-20 Incorrect Climate Posted on: 2020-05-18 The global polar bear population is threatened by loss of sea ice, contrary to PragerU's video claim Claim: The polar bear population has been growing. Polar bears are thriving even where sea ice is diminishing. Source: PragerU, Anonymous, 2020-05-05
