Reviewer 2 and Walker Lee get into the guts of this paper in a lively discussion. Walker's research breaks new ground in stratospheric aerosol geoengineering, raising interesting questions about a more refined technique that potentially creates surprising socio-economic effects.  The paper is in review, full citation is:
