Polar Opposite: Polar Bears Require Thin Ice Or Open Water To Survive
By Kenneth Richard on 5. September 2022

 
Abundant polar bear remains dating to 8000 to 9000 years ago have been found on Zhokhov Island, which is today surrounded by year-round sea ice (even in summer). This Arctic latitude (76°N) is too cold and thus too ice-covered for polar bears to inhabit today.

During the Early Holocene CO2 concentrations ranged between 255 to 265 ppm, and yet the Arctic was 5-7°C warmer than it is today and many regions that are now sea ice-covered were sea ice-free.

For example, Zhokhov Island is tundra and treeless today. It’s surrounded by permanent sea ice, making it inaccessible to wildlife.
 
But during the Early Holocene Zhokhov was so warm that water fowl, birch forests, humans and their domesticated dogs, polar bears, reindeer…all inhabited this terrain. Today’s northern boundary for birch is located 600 km south of Zhokhov Island.

Great post!

So, there was Global Climate Change before Al Gore discovered it?

Has anyone asked the polar bears what they need?

So, the polar bears adapted to the change?

Maybe that Charles Darwin guy was on to something.

I am old enough to remember these scares.......



And please notice that 2006, was about the time the climate scam alarmist changed the name of their scam from "global warming" to "climate change".  That was not an accident.
