Bullet-Point Summary:
Polar bear populations are increasing dramatically during recent decades as the planet has warmed.
The estimated polar bear population has quadrupled since 1950, rising from 10,000 bears in 1950 to 39,000 bears today.
Polar bears evolved between 6 million years ago and 350,000 years ago, surviving and thriving in much warmer climate than today.
Speculation that polar bears are facing imminent demise defy polar bear evolution, polar bear history, and the present state of polar bear populations.
Short Summary:
Polar bears evolved hundreds of thousands of years ago and have thrived during much warmer global climate than today. After dropping to a low of 10,000 bears in 1950, during the middle of a global cooling period, polar bear numbers have quadrupled to 39,000 today.
