THE ECONOMIC DIPLOMACY OF GEOENGINEERING

'Geoengineering' is a new term, still seeking a definition. It seems t o imply something global, intentional, and unnatural. For the radiatio n balance, geoengineering may be fifty years in the future; today's me ans may be out of date then, and the future means are not yet known. I t might immensely simplify greenhouse policy, transforming it from an exceedingly complicated regulatory regime to a problem in internationa l cost sharing, a problem that we are familiar with. Putting things in the stratosphere or in orbit can probably be done by 'exo-national' p rograms, not depending on the behavior of populations, not requiring n ational regulations or incentives, not dependent on universal particip ation. It will involve merely deciding what to do, how much to do, and who is to pay for it.
