1. The most charitable way to describe the result is complete and utter nonsense. I do not want to exaggerate, but this paper is not even a mess.
2. (T)hat study on the polar bear numbers. The problem is that it’s not based on counts of polar bears. It’s based on computer models. So where they have counted the polar bears, as I understand it, all but one sub-population of polar bears are increasing. And there’s one in which a small, and as I remember it, statistically insignificant decrease in numbers. Al the rest of it is computer simulations, based on ice-declines therefore the populations must have gone down. Again, this is a hypothesis, it’s not science.
