Pollution endangering Arctic oceans

Scientists warn pollution could emerge as climate change's "evil twin".

    Though there are few places colder on Earth than the Canadian Arctic, scientists have warned that increasing levels of pollution are not only threatening the polar icecaps, but the world's oceans.

    They say that could mean everything from the smallest fish to the largest sharks are in danger.

    In the second of a three-part series on the Arctic, Al Jazeera's Steve Chao reports on how he spent two weeks with scientists as they investigated what as known as climate change's "evil twin".
