LATEST: Former US Vice President Al Gore has hit back at Bob Geldof's criticisms of his forthcoming Live 8 concerts, insisting the super gigs will be a "wake-up call for the world".
Gore's Live Earth gigs followed Geldof's Live Aid and Live 8 concerts in 1985 and 2005 respectively, which raised awareness of poverty in developing countries.
The Live Earth gigs, which will take place in cities across all the continents, aim to spread the word of the damage global warming is doing to the planet.
Geldof questioned the need for the gigs recently, saying, "Why is (Gore) actually organising them? To make us aware of the greenhouse effect? Everybody's known about that problem for years. We are all f**king conscious of global warming."
In response, Gore replies, "We will have very specific goals that will be very significant and hard-hitting. We will announce those before the concert then empathise them heavily during the concert.
"What Bob Geldof did with Live Aid and Live 8 was fantastic and he has followed up very diligently, as many of the others involved with Live Aid and Live 8 have. I've nothing but good things to say about them.
"These concerts would not be possible in any way without the pioneering and creativity of Geldof and those who helped him.
"But he said in the aftermath of those efforts how important it is to have specific goals and a continuing follow-on effort and we have designed the Live Earth concerts in just that way."
