Salt Lake City Mayor Rocky Anderson has been asked to help Newsweek plan an upcoming magazine issue on the environment.

Anderson was named with about 40 others to the magazine's Global Environmental Leadership Advisory Committee, the mayor's office said Friday. The committee will help the magazine come up with ideas, angles and perspectives for an April cover story on environmental issues.

Other mayors on the committee are Albuquerque's Martin Chavez and Seattle's Gregory Nickels. The committee also includes California Gov. Arnold Schwarzenegger's chief of staff Susan Kennedy, and Wendy Schmidt of the Natural Resources Defense Council.

Anderson has become a prominent national spokesman on environmental issues, especially global warming. In September, he spoke in a panel discussion in New York City on global warming, sponsored by former President Bill Clinton. In November, he hosted his second annual Sundance Summit at Robert Redford's Sundance resort, which brings together mayors from across the country to address climate change.
