As per my earlier email seeking a new definition of "geoengineering", what is the point of lumping all SRM and CDR techniques together and not considering the entire range of mitigation (and possibly adaptation) proposals?
Many CDR techniques (e.g., BECCS, DAC) have far greater similarity with conventional mitigation approaches than they do with spraying aerosols in the stratosphere. see: https://groups.google.com/forum/#!topic/geoengineering/xsD3wqMahbc _______________ Ken Caldeira Carnegie Institution for Science Dept of Global Ecology 260 Panama Street, Stanford, CA 94305 USA +1 650 704 7212 [email protected] http://dge.stanford.edu/labs/caldeiralab @kencaldeira On Tue, Sep 24, 2013 at 3:57 PM, Andrew Lockley <[email protected]>wrote: > Fred > > John Shepherd (cc) did a graphical analysis of this issue, which I found > very helpful. > > I've cc'd him, and maybe he can provide the graph. > > A > On Sep 24, 2013 2:54 PM, "Fred Zimmerman" <[email protected]> > wrote: > >> We spend a lot of time discussing the merits of individual approaches to >> geoengineering and arguing for prioritizing one or the other. >> >> Assuming hypothetically that >> >> 1) all methods, all flavors of SRM/CDR are "approved" by a governance >> authority >> 2) all methods, all flavors are assigned values for "years to deployment" >> and "RF per year" and "cost per unit of RF" >> >> has anyone done an exercise modeling the optimum mix across all >> methods/all flavors? if some methods/flavors are disapproved? if values >> are modified? >> >> >> --- >> Fred Zimmerman >> Geoengineering IT! >> Bringing together the worlds of geoengineering and information technology >> GE NewsFilter: http://geoengineeringIT.net:8080 >> >> -- >> You received this message because you are subscribed to the Google Groups >> "geoengineering" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to [email protected]. >> To post to this group, send email to [email protected]. >> Visit this group at http://groups.google.com/group/geoengineering. >> For more options, visit https://groups.google.com/groups/opt_out. >> > -- > You received this message because you are subscribed to the Google Groups > "geoengineering" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > Visit this group at http://groups.google.com/group/geoengineering. > For more options, visit https://groups.google.com/groups/opt_out. > -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
