Polar bears will have a loss of access to denning areas (BIO, 2015). Polar bears will have an increase in drowning (BIO, 2015). Less ice are there for polar bears (BIO, 2015). More water means more heat and less ice (BIO, 2015). Warmer temperature that thaw ancient permafrost (frozen soils), releasing more green house gases (BIO, 2015). Polar bears will have drop in body condition (BIO, 2015). Polar bears will have an increase in cannibalism (BIO, 2015). There will be lower cub survival rates (BIO, 2015).
