Former Vice President Al Gore, co-winner of the 2007 Nobel Peace Prize for his work on global warming, will speak at Carnegie Mellon University's 111th commencement ceremony at 11 a.m. Sunday, May 18, in Gesling Stadium on the university's Oakland campus.

Carnegie Mellon President Jared L. Cohon described Mr. Gore as the nation's leading advocate for the environment and said he is pleased the university's graduates will have an opportunity to hear from him.

"He is an inspiring and committed leader, whose beliefs fit well with our university, an institution committed to sustainable, green practices," Dr. Cohon said. "His impassioned campaigns have led him to some of the world's greatest honors. And we are greatly honored to have him at Carnegie Mellon."

In addition to sharing the Nobel with the United Nations' Intergovernmental Panel on Climate Change, Mr. Gore is an author of the best-sellers "Earth in the Balance" and "An Inconvenient Truth," which was the subject of an Oscar-winning documentary.
