Instead of creating new carbon sinks maybe we can try and preserve our existing carbon sinks - like our rainforests -

I have seen the views of a commercial group (Planktos) and also a report by people working with an Indian scientific survey in the Southern Ocean. People seem to be mainly interested in whether a lot of carbon is sequestered. What about the other side? There are vast areas of the oceans where no fish can be caught, and other places where over fishing goes on. How about a bit of careful fish farming, fertilizing places just a bit outside the present fishing grounds so that increased amounts of plankton become available? A little more carbon sequestered and a few more fish to eat would still be a step forward.

Thanks for your clear summary about this interesting, rather scary idea. I’ll look forward to hearing more from Law and Boyd on Our Changing World.

This carbon pickle has generated all number of wild ideas. I think my favourite is the idea of realeasing an orbiting dust cloud into the atmosphere to shade us from the sun’s rays. http://www.newscientist.com/blog/environment/2007/02/far-out-schemes-to-stop-climate-change.html?feedId=earth_rss20

Frankly, I think we need to concentrate our energies on looking at how we can reduce our energy consumption. I’m open to geo-engineering ideas but given our record I think we’re better off to look at carbon-reduction solutions.

Otherwise we may find ourselves in a situation that resembles a science fiction film…..
