Pharrell steers Live Earth concerts
Pop superstar Pharrell Williams is to oversee a series of Live Earth concerts around the world to draw attention to climate change.
The concerts were last staged in 2007 and included a major show at Wembley Stadium, although this year's events do not include a UK performance.
US vice president Al Gore teamed up with Williams and producer Kevin Wall to announce six Live Earth: Road to Paris concerts which are designed to focus attention on the United Nations Climate Change Conference in the French capital in November.
The concerts will take place on June 18 with more than 100 major stars taking part at shows in Paris and New York, as well as locations in Brazil, South Africa, China and Australia.
Announcing the shows at the World Economic Forum in Davos, Switzerland, organisers said they expected the shows to be seen by a global audience of two billion people.
The aim is to encourage world leaders to adopt a new climate accord at the Paris talks.
The 2007 Wembley concert attracted the likes of Madonna, Foo Fighters, Kasabian and The Black Eyed Peas. Williams also took part back then, at Copacabana Beach in Rio De Janeiro in Brazil.
