What are the impacts of Global Warming in the Arctic Region?

Global warming has resulted in the melting of ice which in turn effects Polar Bears. These bears hunt seals on ice, and the reduced amount of ice has led to shorter hunting sessions. The bears rely on body fat to ensure their survival during the summer, however in the present each bear loses 80kg of fat during the summer, making diseases easier to spread to them. This will then effect the reproduction of cubs and the feeding of them, meaning fewer cubs will be born leading to an eventual extinction. Furthermore, 155000 people live in the Arctic region, and their lifestyles are being affected due to global warming. Weaker ice means every winter when the Inuit Tribe head off for fishing they are in more danger of the ice collapsing,causing deaths and injuries. Settlers have also been forced to move further inland due to the amount of ice decreasing around the villages which normally acts a protection from waves and storms, leaving them vulnerable now. As the number of fish decreases, the villagers will suffer from a decrease in protein and nutrients, leaving them to buy imported food which is very expensive.
