I don't understand all the negative comments. Because it seems indeed to be the case that Polar bears are not doing that bad over the last 20 years [1]. Is climate warming a problem for Polar bears? Yes, definitely! But much less than we think. By far the biggest cause of the decline of Polar bears in the last century has been hunting. Only when Polar bears were put on the endangered list, and hunting was reduced, the Population have been increasing again. [3] Now that Polar bears are not hunted anymore, the melting ice becomes their prime problem. But Polar bears have survived warming climates in the past [4]. They are smart animals that have adapted to many different climates in the past and one could, arguably, assume that they could survive this one as well [5]. I'm not saying that it doesn't matter if the North pole melts. But it seems not to be as big of a treat for Polar bears as we believe it is.
