In environmental news, a new study on climate change in the Arctic shows that polar bears may go extinct by the end of the century due to global warming. The study is the work of over 300 scientists who have conducted the most comprehensive assessment of Arctic climate change over the past four years. The scientists determined the Arctic has warmed 10 times as fast as the world as a whole. Robert Corell, a senior fellow at the American Meteorological Society, said, “The Arctic is really warming now. These areas provide a bellwether of what’s coming to planet Earth.”
