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.”
