A series of concerts "bigger than Live Aid" is being planned for July, in a bid to put the subject of climate change before an audience of a global audience of 2bn.
The event, scheduled for July 7, will feature co-ordinated film, music and television events in seven cities including London, Washington DC, Shanghai, Rio de Janeiro, Cape Town and Kyoto, with major broadcasters and media owners aiming to extend the reach of public awareness of global warming.
It is understood that former US vice-president Al Gore, whose movie An Inconvenient Truth brought climate change to cinema audiences last year, will announce the event tomorrow in London.
The organisers hope to involve up to 2.5m people in events and link-ups at the cities involved, as well as other locations.
They are promising a line-up of artists to "dwarf" that of the Live8 and Live Aid concerts, thought to be branded under the name "SOS".
One person close to the event said yesterday: "The talent involved is just exponentially bigger because the issue itself is bigger.
"Live Aid was about asking people to stump up money, this is about effecting systemic change.
"The aim is not just to drive awareness but to get people to take action."
These actions are likely to include personal pledges to reduce emissions, for instance by using energy efficient equipment or flying less.
