The problem with what common person feel as obvious is that is based in common person knowledge. People is often unable to see (or refuse to see) the whole picture about a field that they don't master. It does not mean if is informatics, or ecology. To start, the title in HN is misleading. Without access to the full article, I can't really discuss the job, but I have a few mental questions to myself that would need to be addressed. Maybe they are discussed in the article, maybe not. If all known populations of bears appear in areas with at least a little of sea ice, and none in areas without sea ice; I think that the answer to the question "would polar bears survive if the sea ice vanishes?" is not difficult to deduce. In any case the last lines of the link: "correction, we didn't mean to say that polar bears can survive without sea-ice" are self-explanatory.
