<div>Also, personally I'd be building a *lot* of nuclear reactors, and shutting down coal power stations. Especially here in good-ole uranium rich, tectonically inert Australia. Build a few more than we need to power some bitchin' desalination plants, and we just might be able to keep living on this denuded dirtwad for a coupla more years. But that's just me...

<br>> >Any though as to how one might show something to Richard Branson?<br>> why, yes, in general terms:<br>> Airline tycoon Richard Branson has announced a<br>> $US25 million ($A32m) prize for the first person
<br>> to come up with a way of scrubbing greenhouse<br>> gases out of the atmosphere in the battle to beat global warming.<br>> Flanked by climate campaigners former US<br>> vice-president Al Gore and British ex-diplomat
<br>> Crispin Tickell, Sir Richard said he hoped the<br>> Virgin Earth Challenge would spur innovative and<br>> creative thought to save mankind from self-destruction.<br>> The prize will initially be open for five years,
<br>> with ideas assessed by a panel of judges<br>> including Sir Richard, Mr Gore and Mr Tickell as<br>> well as Australian environmentalist Tim Flannery,<br>> US climate scientist James Hansen and Briton
<br>> James Lovelock. "Man created the problem and<br>> therefore man should solve the problem," he said.<br>> "Unless we can devise a way of removing CO 2<br>> (carbon dioxide) from the Earth's atmosphere we
<br>> will lose half of all species on Earth, all the<br>> coral reefs, 100 million people will be<br>> displaced, farmlands will become deserts and rainforests<br>> wastelands."<br>> Sir Richard rejected suggestions that he, as an
<br>> airline owner, was being hypocritical in offering<br>> the prize. "I could ground my airline today, but<br>> British Airways would simply take its place," he<br>> said, noting that he was investing in cleaner engines and fuels.
<br>> Top scientists predict that global average<br>> temperatures will rise by between 1.8 and four<br>> degrees this century due to human activities such<br>> as burning fossil fuels, putting millions at risk
<br>> from rising sea levels, floods, famines and storms.<br>> Mr Gore, whose campaign film An Inconvenient<br>> Truth has helped spread the message, said all<br>> science showed something was drastically wrong
<br>> but that Armageddon was not inevitable.<br>> The winner must devise a way of removing 1<br>> billion tonnes of carbon gases a year from the<br>> atmosphere for 10 years with $US5 million
<br>> ($AS6.4m) of the prize being paid at the start and the rest at the<br>> end.<br>> If no winner is identified after five years the<br>> judges can decide to extend the period.<br>> "This is the world's first deliberate attempt at
<br>> planetary engineering," Dr Flannery said via<br>> video-link from Sydney. "We are at the last<br>> moment. Once we reach the tipping point it will<br>> have been taken out of our hands."
