We do not want to be in a situation where a solar geoengineering system is used to enable continued increases in CO2 emissions.
Therefore, a reasonable demand is that no new smokestacks or tailpipes be built after a solar geoengineering system is deployed. Another way of phrasing this is to demand that new construction of all new CO2-emitting devices cease prior to any solar geoengineering system deployment. This would help address the concern that solar geoengineering could provide cover for continued expansion of CO2-emitting industries. Norms that would prevent simultaneous solar geoengineering deployment and increasing CO2 emissions would help diminish the likelihood of bad outcomes and could help broaden political support for solar geoengineering research. -- This would limit deployment of solar geoengineering systems to the case of "catastrophic" outcomes and would not permit use of solar geoengineering for "peak shaving" amid promises of future reductions in CO2 emissions. Thus, this proposal does have a substantive implications for "peak shaving" strategies. -- *I am floating this idea without being certain that the formulation presented here is the best possible formulation.* _______________ Ken Caldeira Carnegie Institution for Science Dept of Global Ecology 260 Panama Street, Stanford, CA 94305 USA +1 650 704 7212 kcalde...@carnegiescience.edu http://dge.stanford.edu/labs/caldeiralab @kencaldeira -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
