Hi All

Jonathan Marshall writes about the cost of geoengineering proposals that  'Nearly all of them require massive tax-payer subsidies . . ',    Other people have written that they are so cheap that some private individuals could afford them.

We only need one cost-effective technology to remove the objection.  I hope that it will be possible to have one with the annual costs of reversing warming to date below those of international climate conferences. If anyone wants a paper  giving the supporting arguments, please contact me.
