The Polar Bear "species" is 100% safe from global warming
Environmental "scientists", I believe have been guilty of Species Inflation with regards to polar bears. One of the things that evolutionary and genetic science has given us is a "tight" definition of a species. Ignoring the look, habitat and lifestyle and just concentrating on the genetics, polar bears are a sub-species of the brown bear. Focusing on the plight of the white bears is just racism.
