Dr. Steve Amstrup, a polar bear specialist, emphasizes that global warming is the single biggest threat to polar bears. The decline in their habitat is directly linked to the increase in greenhouse gas concentrations. Dr. Amstrup describes the process of global warming and talks about the relationship between climate and weather. Despite some uncertainties, scientific consensus supports the understanding that a warmer world will lead to less sea ice, posing dire consequences for polar bears.
