The article is mostly about global warming and contains a wealth of citations / references / relevant links. They provided their evidence as to why it's not a jump to link it to global warming -- where is your evidence that it is, in fact, a jump?

The polar bear situation really doesn't look like good evidence to me, they state the bear's lameness is assumed to be due to starvation-based atrophy but it seems as likely that this is just an injured bear that can't hunt effectively. I'm certainly not denying climate change is wiping out polar bears, just that this shows good evidence of that. The article states bears starve through summer until sea ice forms on which they catch seals .. but the image is from Summer, when the sea ice presumably is yet to form. I guess it could be cumulative from the previous Summer being too warm; again it's not good, clear evidence as it's presented. Could someone answer where the seals go? I'd have expected if they weren't resting/mating on sea-ice that they'd rest on land and actually be easier to catch? Do they instead stay at sea?

  In the winter seals have to use holes in the ice to breath, which makes them very vulnerable. Without ice it is much more difficult for bears to catch them. http://www.athropolis.com/arctic-facts/fact-seal-breathing.htm http://www.athropolis.com/arctic-facts/fact-seal-breathing.h...

    Yes, but it's the late Summer period I'm asking about, can the bears not feed at all until the sea is completely frozen over?

Well the argument in the article is "By telling the story of one polar bear, Nicklen hopes to convey a larger message about how a warming climate has deadly consequences." But that particular bear is probably old and sick and its problems likely not caused by warming such. I guess you can use it as an illustration of how you think warming may be bad.
