Claim reviews
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.”

Climate scientists agree that human-caused greenhouse gas emissions are primarily responsible for climate change, contrary to claims in Clear Energy Alliance video
