Today is: International Polar Bear Day Staff reports International Polar Bear Day, a day organized by Polar Bears International, draws attention to the threats that polar bears face in the warming Arctic, as a result of carbon dioxide and other greenhouse gases. The day is dedicated to reflecting on what can be done to help polar bears, and how carbon emissions can be reduced. Arctic warming has already had an effect. For example, in Western Hudson Bay there were about 1,200 polar bears in 1987, but by 2012 there were only 900. Climate change has lead to lower body weights in polar bears; lower body weight in females has affected their offspring, yielding smaller litters and causing fewer cubs to survive.
