Description:

This paper briefly discusses how climate change has directly affected polar bears due to their dependence on ice and cold as means for survival. The paper argues that if we do not change our current daily actions, polar bears have a high probability of facing extinction and how expected changes affecting polar bears due to climate change include increased interaction with humans and polar bears, reduced access to food supplies, reduction in population size, reduced body composition and lower adult survival rates.

From the Paper:

"Polar bears are categorized as "indicator" species because their welfare reveals the general state of an ecosystem. The increasing reduction rate of polar bears indicates the poor conditions of the Arctic. "Decreasing sea ice negatively impacts population growth. Climate change models predict that, as global temperatures rise, periods of reduced sea ice will occur more frequently" (Cole). Although climate change varies and episodes of reduced ice increase, polar bear populations "can't recover in between bad years, so they end up declining over time," stated Hal Caswell, a senior scientist at Woods Hole Oceanographic Institution (Cole). Recorded evidence projects findings of a decreased polar bear population. In the Hudson Bay area in Canada, there has been a twenty five percent reduction in the amount of polar bears than there were twenty five years ago (Cole)."
