<br><br>why, yes, in general terms:<br><br><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><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><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><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 wastelands."<br><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><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><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><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 end.<br><br>If no winner is identified after five years the
<br>judges can decide to extend the period.<br><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."<br><br>REUTERS<br><br><br>_______________________________________________<br>extropy-chat mailing list<br><a href="mailto:extropy-chat@lists.extropy.org">extropy-chat@lists.extropy.org
