One approach is to multiply historical extrapolation of global emissions by a factor with a decline from 1 to a smaller multiple, e.g. on a timescale of about 30 years. *Another allows for solar radiation management via anthropogenic stratospheric sulfur injection by one or more of sixteen geographic regions, in order to limit global average temperature to a chosen target level. An economic measure of impacts on human welfare is compared for different versions of these two approaches. *That measure is time-integrated discounted utility of per capita consumption. That measure is computed with and without empathy, which involves geographical regions counting part of others’ welfare as part of their own. Inter-regional fund transfers that cover all or part of a region’s expenditures used for limiting carbon emissions can be used to encourage broader inter-regional cooperation. These exercises pose interesting questions about how choices will ultimately be made between use of one or both of carbon emissions limitations and solar radiation management. *Source: Research Square * -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
