B-roll, captioned photos, or further information, please info@pbears.org Polar bears will probably die in minutes if they are bred in warm habitats. Sci… Scientists have developed a new study, showing the impact of climate change on polar bears. Over 97% of climate scientists agree that human activities are causing the current warming and related climate disruption. The female polar bear, also known as a sow, weighs about half the weight of the male. The first involves the decline in Arctic ice coverage over the past three years, and the second involves the official listing of the polar bear as a threatened species in May 2008. The laws of physics dictate that the world will grow warmer and warmer as greenhouse gas concentrations rise. Sea ice loss is affecting the polar bear’s way of life. Speculation that polar bears are facing imminent demise defy polar bear evolution, polar bear history, and the present state of polar bear populations. Polar bears have quite many adaptations to survive in extreme cold weather. Many researchers have predicted a wide range of impacts of climate change on polar bear demography and conditions. Furthermore, polar bears can sometimes get overheated even in Arctic weather if they run for a few minutes continuously. Not at all. It’s more than just polar bears being affected.
