Geoengineering - a part of climate change policies Kjetil Gramstad and Sigve Tjøtta Abstract International efforts on abating climate change, focusing on reductions of greenhouse gas emissions, have thus far proved unsuccessful. This naturally motivates exploration of other strategies. We present a framework for analyzing stratospheric sulphur injections. We adopt and modify the Dynamic Integrated model of Climate and the Economy (DICE), to utilize a cost-benefit analyze of this geoengineering option. Both benefits and costs of stratospheric sulphur injections are highly uncertain. Our model simulations suggest that stratospheric sulfur injections may have a substantial beneficial effect on overall welfare. For this effort to fail a cost-benefit test, the ratio of cost to benefit must be—what we consider—very large. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
