Some might recall that BBC did an hour-long documentary<http://news.bbc.co.uk/2/hi/programmes/6298507.stm>on Geoengineering about three years ago called *Five Ways to Save the World that had detailed discussion on five most popular techniques. * * * *Three of those were SRM methods -- sunshade, sulfur dioxide and cloud boosting -- and two were CDR methods -- ocean fertilization and synthetic trees. *
It was quite entertaining with interviews with the scientists and graphic visualisations... available on Google Video<http://video.google.com/videoplay?docid=286000425078890061> Manu On Fri, Dec 11, 2009 at 3:16 AM, John Nissen <[email protected]> wrote: > > Hi all, > > Two excellent programmes on the environment and mankind's impact: > > David Attenborough: > > http://www.bbc.co.uk/iplayer/episode/b00pdjmk/Horizon_20092010_How_Many_People_Can_Live_on_Planet_Earth/ > > > Iain Stewart: > http://www.bbc.co.uk/iplayer/episode/b00jf6md/Hot_Planet/ > > Unfortunately, although Iain had sympathetic mention of Klaus Lackner's > artificial trees, solar radiation management was represented by sulphur > being fired into the stratosphere by guns - mention of ozone disruption > - and the programme ended with punch line "geoengineering is too > expensive and too dangerous".
