Don't see how denigrating Gore makes climate change anymore of a hoax. At best, he had just made far more people aware of it, and persuade more scientists study its causes and effects.
As far as so-called increase in total polar bear population, their estimations vary widely and wildly, b/c they are being counted in groups in remote and nearly inaccessible locations. So while one group could be estimated as an increase. another could be seen as stability maintained, and yet another as having decreased in number.
Under current estimates of further loss of sea ice under climate change studies, ~2/3rds could be gone by mid-century.
