Draft title: the historical and biological affect of climate change on polar bears. Polar bears across the arctic face shorter sea ice season by michelle ma. Polar bears rely on sea ice to catch their main prey which are seals. This article is an important asset to answering the question of what the correlation between the evolution of polar bears and climate change is. Conducting a research project on this topic will lead to a better understanding about the consequences of polar bears having longer or changing ice-free periods. The research states that over the past 35 years, polar bears have lost a total of seven weeks of sea ice habitat (ma, 2016). It also states that if global warming continues at the same rate, another six or seven weeks of no sea ice habitat will affect the lives of polar bears by mid-century (ma, 2016).
