*Abstract* Stratospheric aerosol intervention (SAI) is a proposed strategy to reduce the effects of anthropogenic climate change. There are many temperature targets that could be chosen for a SAI implementation, which would regionally modify climatically relevant variables such as surface temperature, precipitation, humidity, total solar radiation and diffuse radiation. In this work, we analyse impacts on national maize, rice, soybean and wheat production by looking at output from 11 different SAI scenarios carried out with a fully coupled Earth system model coupled to a crop model. Higher-latitude nations tend to produce the most calories under unabated climate change, while midlatitude nations maximize calories under moderate SAI implementation and equatorial nations produce the most calories from crops under high levels of SAI. Our results highlight the challenges in defining ‘globally optimal’ SAI strategies, even if such definitions are based on just one metric. -- Alan Robock Alan Robock, Distinguished Professor Editor, Reviews of Geophysics (Impact Factor 25.2) Chair, AGU College of Fellows Department of Environmental Sciences Phone: +1-848-932-5751 Rutgers University E-mail:[email protected] 14 College Farm Roadhttp://people.envsci.rutgers.edu/robock New Brunswick, NJ 08901-8551 USA ☮https://twitter.com/AlanRobock -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
