Global warming is an issue that affects the whole world. In the polar lands global warming raises temperature which melts the polar caps, this means that the melting ice will raise ocean levels and eventually flood the world. Around the Arctic Peninsula they have risen 2.5 degrees in 50 years. This source is reliable, but I would not trust the source 100% as it is not a government run site.
The Polar lands is home to an average temperature of minus 22 degrees Fahrenheit. The Arctic is inhabited, which means it has people living there. It also has a variety of animals that call the Arctic home. Some of the mammals that live here include polar bears, arctic foxes, arctic wolves, narwhals, sea lions, orcas, walrus, seals, and other types of whales. This source is on the border o being reliable, it is not government run and the websites name doesn't seem legit but the information provided seems legitimate.
