Alicia Keys performed in Olso, Norway, last night at a concert honoring Nobel Laureate Al Gore. The purpose of the concert was to raise global warming awareness among young people.

Keys said the Nobel Peace Prize underscores how the efforts of one person, such as civil-rights leader the Rev. Martin Luther King Jr., can make a difference.

"For me, the Nobel Peace Prize is an extremely distinguished award for people who truly do serious work to make major change in the world," the 26-year-old singer said, according to the Associated Press.

Don Cheadle and George Clooney have been chosen to receive the Peace Summit Award, which is an honor doled out at the annual world summit of Nobel Peace Prize laureates. The co-stars in the infamous Ocean's films are being honored for their work to bring peace to Darfur.

Over the past two years Clooney and Cheadle have both traveled to the African nation to bring attention to the plight of war refugees there, spoken to government leaders about the ongoing ethnic and tribal conflict in the region and appeared in the 2007 documentary Darfur Now.
