Global polar bear population size is about 28,500 when updates are included

Yet another fake climate scare fails to materialise. But don’t expect DiCaprio, CNN, BBC, ABC or their chums at Greenpeace and WWF to be celebrating this one. Their guaranteed silence telling.


Polar bear numbers have risen since 2005, no matter how you look at it:

Svalbard polar bear Jon Aars_Norsk PolarinstituttUSGS estimated 24,500 (average) polar bears in 2005.

IUCN estimated 26,500 (average of 22,000-31,000) in 2015
(assessment completed in July, released in November).

Subpopulation surveys completed or reported after July 2015 (Baffin Bay, Kane Basin, Barents Sea) added ~2,000 bears.

This brings the adjusted average total at 2015 to ~28,500.
