Let's fact check this nonsense with the figures on polar bears put together by the United States government. Oh, the population of polar bears at least doubled since 1970. Well that puts to rest this BS. http://www.factcheck.org/2008/06/polar-bear-population/
The most important point is that whatever happened in the past is really irrelevant. Polar bear habitat is disappearing due to global warming. Even the most careful on-the-ground management doesn't matter if polar bears don't have the required habitat.
And yet polar beats are thriving better than ever during the past decade... While you post nonsense claiming their numbers did not increase. Is there any depth that your absurd fabrications will not sink to?
Do you even understand the feeding habits of polar bears. They are best fed in summer when the ice breaks up and they have easy access to food. They have a much rougher time surviving in winter when everything is iced over and access to food is a significant problem. Their population declined in the 1970s when there was much more ice and it was colder. The primary cause of this was that the polar bears were starving to death due to the harsh, cold climate.
Another goofy warmist prediction: ----------------------------------------- BRRRR… 12.13.13 5:45 AM ET The End of the Arctic? Ocean Could be Ice Free by 2015 http://www.thedailybeast.com/articl...e-arctic-ocean-could-be-ice-free-by-2015.html
Polar bears survived (and thrived during) the Medieval Warm Period. A time which was warmer than today and it is likely a northern passage above Canada was ice free and navigable during.
