Hi All

James Fleming writes that we cannot test geo-engineering on smaller than planetary scale.

There is a description of a small practical test at

http://www.see.ed.ac.uk/~shs/Climate%20change/Field%20trial%20simulation.doc

and an idea for a larger-scale computer experiment to locate good and bad places at

http://www.see.ed.ac.uk/~shs/Climate%20change/Pseudo%20random%20explanation2.pdf

The first would improve accuracy and increase add confidence in the predictions of the second. Criticism and suggestions for improvements would be welcome.

Ken has pointed out that we are already carrying out an dangerous planetary test which we do not understand. Lowell says that we started it thousands of years ago.
