Target: Al Gore and his concert extravaganza. Using detailed numbers generated by climate scientists, they positively tear Gorezilla's head off with this blistering article denouncing the rank hypocrisy of the whole affair.
No doubt to rapturous applause, Madonna will call for mass global change to reduce carbon emissions and to tackle 'climate crisis'.
Watching the veteran star lap up the adoration, her entourage could, however, be forgiven for exchanging slightly jaded glances - having witnessed her jet in for the concert from New York. For her 2006 World Tour, she flew by private jet, transporting a team of up to 100 technicians and dancers around the globe. Waiting in the garage at home, she has a Mercedes Maybach, two Range Rovers, an Audi A8 and a Mini Cooper S.
Indeed, Madonna's carbon footprint is dwarfed only by her ego - she has vowed that she will 'speak to the planet' at Wembley. In fact, an apology might be in order - for the superstar's energy consumption is only the tip of the iceberg in this epic vanity-fest.
The Live Earth event is, in the words of one commentator: 'a massive, hypocritical fraud'.
For while the organisers' commitment to save the planet is genuine, the very process of putting on such a vast event, with more than 150 performers jetting around the world to appear in concerts from Tokyo to Hamburg, is surely an exercise in hypocrisy on a grand scale.
Matt Bellamy, front man of the rock band Muse, has dubbed it 'private jets for climate change'.
A Daily Mail investigation has revealed that far from saving the planet, the extravaganza will generate a huge fuel bill, acres of garbage, thousands of tonnes of carbon emissions, and a mileage total equal to the movement of an army.
The most conservative assessment of the flights being taken by its superstars is that they are flying an extraordinary 222,623.63 miles between them to get to the various concerts - nearly nine times the circumference of the world. The true environmental cost, as they transport their technicians, dancers and support staff, is likely to be far higher.
The total carbon footprint of the event, taking into account the artists' and spectators' travel to the concert, and the energy consumption on the day, is likely to be at least 31,500 tonnes of carbon emissions, according to John Buckley of Carbonfootprint.com, who specialises in such calculations.
Throw in the television audience and it comes to a staggering 74,500 tonnes. In comparison, the average Briton produces ten tonnes in a year.
The concert will also generate some 1,025 tonnes of waste at the concert stadiums - much of which will go directly into landfill sites.
Moreover, the pop stars headlining the concerts are the absolute antithesis of the message they promote - with Madonna leading the pack of the worst individual rock star polluters in the world.
Oh, there is a LOT more. This is a long, detailed, brutal denunciation of all things Gore. The Mail is not buying the "carbon offset" fraud, either. They lay that one out - hard.
So just how does Gore claim that Live Earth will be carbon neutral? He does so by convenient use of 'carbon offsetting' - a trendy new method of absolving yourself of guilt.
Carbon offsetting involves 'neutralising' the emissions you are responsible for by buying 'credits'. A spokesperson for Live Earth says: 'This might involve buying environmentally sound lightbulbs for a Third World school, planting trees, or installing solar panels in a developing country.'
A huge industry has sprung up to provide corporations with carbon credits. However, critics say that the practice is simply a way for consumerist industries and nations to export their responsibility to developing countries. Others say it simply does not work.
Carbon-offsetting is, it turns out, how celebrities square green issues with their extravagant lifestyles and use of private jets.
Jon Bon Jovi has said: 'We wrote a cheque, we took care of our footprint and raised awareness, blah blah blah.'
This one is well worth the read. Very detailed and very, very damning.
