Nat Geo reported in 200 that the Sun was getting warmer and that 4.5 billion years ago the earth's orbit around the sun was in the "habitable zone". As of the year 2000 the earth was on the verge of crossing into the "uninhabitable zone". Astronomers and physicists say that the earth will get hotter and more humid as the sun continues to get hotter. This is a multi billion year process and don't think it will reverse itself as the sun finishes out its life-cycle.

Kassie Siegel is a lawyer, not a scientist. You would think they wold at least have a biologist do the doom saying from their organization. I guess they want to maintain credibility...

"They also like to point out that hes a signatory of the Manhattan Declaration, which questions the very existence of climate change." Ah yes, the tolerance of the intellectual left who claims the "science is settled" - so long as they are able to silence everyone who disagrees with them.

Great article. I go up to Western Hudson Bay to photograph the moms and babies yearly. Some years we have great sightings and other years the sightings are tough to come by. It seems to go in cycles and no one seems to know why.
This is from one of our better years: http://www.harveywildlifephotography.ca/#/north-american-wildlife/north-american-bears/polar-bear-moms-and-cubs-2013/Wapusk_Polar_Bear_home_page

@Cris:" Seals and such go to the ice to breed. When the ice is not there, where do they go? To the land to wait for the ice. Where are the bears? On the land of course. Think about it."
Seals can swim as far as they have to, to find ice. Polar bears can`t (they`re good swimmers, but not as good as seals). Most importantly, females with cubs are less mobile (and more vulnerable) than males. If other species than the mostly too big to catch walruses give birth on land, the pups will be sitting ducks: Harp seal pups f.ex. are not able to swim until they are about two months old. Great for the bears for a while, but hardly a sustainable situation in the long run. As long as there is an ice sheet in March and April when the pups need it the most, the seals will reach it. The bears might not. Think about it some more.

Thank you for a balanced article on a truly ravel'd topic.

so guess what the human population is thriving.. but by 2050 there is going to be a serious collapse due mainly to GHG emissions impacts.

Polar collapse will probably proceed human collapse.

Excellent Article, if only our lives were beautiful as a polar bear's soft crystal white fur :)

This is a different story to the exaggerated one told by Andy Derocher in 2010, when he said polar bear population in western Hudson Bay could die out in approximately 25 to 30 years.

Yes a nice balanced article and really highlights overall we really don't know what is going on. Those interested in what is happening to the sea ice can go to the NSIDC website. It seems that the ice is actually doing OK too so the polar bear should be safe for a while yet.
