In the State of the Polar Bear Report 2021, published by the Global Warming Policy Foundation (GWPF) ahead of International Polar Bear Day, zoologist Dr. Susan Crockford explains that while the IUCN Polar Bear Specialist Group (PBSG) promotes the impression that polar bear population numbers are declining, the results of recent studies indicate otherwise.
Crockford further clarifies that the global population estimate used by the PBSG has not been updated since 2015, even though the results of numerous surveys have been published since then.
These additions bring the global population total to almost 32,000, up from about 26,000, albeit with a wide range of potential errors.
This modest increase is consistent with a species recovering from low numbers brought about by overhunting after focused international protection was introduced in 1973.
Dr. Crockford reports that there were three serious attacks by polar bears on people in 2021 but no fatalities.
She explains that there were no reports of widespread starvation of bears, acts of cannibalism, or drowning deaths that might suggest bears were having trouble surviving the ice-free season.
“The current health and abundance of polar bears continue to be at odds with predictions that the species is suffering serious negative impacts from reduced summer sea ice blamed on human-caused climate change.”
