Scientists recently discovered new evidence of the trend toward global warming. Blue mussels, which normally favor warm water, were found 800 miles from the North Pole, where they have not been recorded for a thousand years. In Canada, Inuit reported seeing robins for the first time. “The climate is changing fast,” said Geir Johnsen of the Norwegian University for Science and Technology. Mollusks are a “very good indicator that the climate is warming.” (Yahoo September 18)

According to U.N. scientists, the Arctic is the fastest-warming region in the world. As higher temperatures melt snow, the dark ground beneath it is exposed, accelerating warming trends and increasing climatic changes.
