Alicia Keys was to join fellow artist Kylie Minogue, Annie Lennox and Melissa Etheridge Tuesday night at a concert honoring Nobel Peace laureates Al Gore and the United Nations climate panel.

Gore and the U.N. Intergovernmental Panel on Climate Change shared the Nobel Peace Prize for their efforts to document and spread the word about what the former vice president calls the “planetary emergency” of global warming.

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.
