In the 24 June issue of New Scientist, Ed Hawkins, University of Reading, UK, and Alan Robock, Rutgers University, New Jersey, USA, both are quoted as observing that we really do need, urgently, to invent a way to remove Carbon dioxide from the atmosphere on a huge scale.
The classic way of solving a problem is to find a mirror image problem and put the two together. Link farming (globally we need more food) and urban waste production (as global population and wealth rise, we get more unban waste) in the right way and that could deliver the invention. Well, we already have it and it has been done and on a scale that could be applied globally.
