Alaska polar bear researchers claim poor sea ice limited spring field work in 2021 more than 2019

The reporter tries to paint a picture of polar bears suffering harm from these recent conditions but in fact there is no published data from the Southern Beaufort after 2016, and any effects claimed to have been documented in bears up to that year have not been conclusively demonstrated to have been caused by sea ice loss (Crockford 2021) because a correlation is not evidence of causation.
