Narwhals more at risk than polar bears:?Study

The polar bear has become an icon of global warming vulnerability, but a new study has found an Arctic mammal that may be even more at risk to climate change: The narwhal.

The narwhal, a whale with a long spiral tusk that inspired the myth of the unicorn, edged out the polar bear for the ranking of most potentially vulnerable in a climate change risk analysis of Arctic marine mammals.

The study was published last week in the peer-reviewed journal Ecological Applications. Polar bears are considered marine mammals because they are dependent on the water and are included as a species in the U.S. Marine Mammal Protection Act.

Scientists from three countries quantified the vulnerabilities that 11 year-round Arctic sea mammals have as the world warms.
