Al Gore has recruited Australian-based Cathy Zoi to run the Alliance for Climate Protection he set up six months ago.

"It will be the first great note in a worldwide song demanding change that will be heard on every continent in every time zone," Zoi says of the concerts.

"Post Live Earth, the Alliance for Climate Protection is undertaking a three- to five-year campaign to educate people from all walks of life that the climate crisis is both critically urgent and something we can solve."

One such action is the Live Earth's outreach program, called Friends of Live Earth. Some 6000 people have applied for kits to run their own events simultaneously with the concerts.

A key part of Live Earth will be to get people around the world to sign a seven-part pledge that commits them to lobby their governments.

This is much more than a feel-good exercise: the event organisers plan to capture a massive database of people who can be mobilised in future campaigns - and be asked to do

They just multiply CO2 emissions by the actions like this. Hypocrisy.
