Polar bears make for false idols

being similarly portrayed as effects of global warming.

One reason that the 2007 predictions of future polar bear survival were so far off base is that the model developed by American biologist Steven Amstrup (now at Polar Bears International, an NGO) assumed any polar bear population decline would be caused by less summer open-water season, which is particularly conducive to fishing: These seals do most of their feeding in summer. More food for seals in summer means more fat seal pups for polar bears to eat the following spring, a result that’s probably true throughout the Arctic.

As long as polar bears have lots of baby seals to eat injury, tooth decay and illness. Some cancers induce a muscle-wasting syndrome that leads to faster-thanusual weight loss. This is likely what happened to the emaciated Baffin Island bear captured on video in July 2017 and promoted by National Geographic late last year. The videographers claimed it showed what starvation due to sea-ice loss looked like — an implausible conclusion given the time of year, the isolated nature of the incident, and the fact that sea ice that year was no more reduced than previously.

That starving-bear video may have convinced a few more gullible people that only hundreds of polar bears are left in the world. But it also motivated others to locate the International Union for Conservation of Nature (IUCN) Red List report for 2015 that estimated global polar bear numbers at somewhere between 22,00031,000, or about 26,000, up slightly from 20,000-25,000, or about 22,500, in 2005. Newer counts not included in the 2015 assessment potentially add another 2,500 or so to the total. This increase may not be statistically significant, but it is decidedly not the 67-per-cent decline that was predicted given the ice conditions that prevailed.

The failure of the 2007 polar bear survival model is a simple fact that explodes the myth that polar bears are on their way to extinction. Although starving-bear videos and scientifically insignificant research papers still make the news, they don’t alter the facts: Polar bears are thriving, making them phoney icons, and false idols, for global warming alarmists.
