A Simple Model To Account For Regional Inequalities In The Effectiveness Of Solar Radiation Management, Juan B. Moreno-Cruz, Katharine L. Ricke, David W. Keith
A Simple Model To Account For Regional Inequalities In The Effectiveness Of Solar Radiation Management, Juan B. Moreno-Cruz, Katharine L. Ricke, David W. Keith
Juan B. Moreno-Cruz
We develop a simple measure of the potential effectiveness of solar radiation management (SRM) in compensating for anthropogenic climate change and test this measure using data from an ensemble of modeling experiments conducted with a general circulation model (GCM). Assuming a linear relationship between the amounts of SRM implemented globally and the regional temperature and precipitation responses to that change, we calculate the amount of SRM that minimizes impacts using three different social objectives: egalitarian, utilitarian and ecocentric. While inequalities in the effectiveness of SRM between regions are important, they may not be as severe as is often assumed. When …
Climate Policy Under Uncertainty: A Case For Solar Geoengineering, Juan B. Moreno-Cruz, David W. Keith
Climate Policy Under Uncertainty: A Case For Solar Geoengineering, Juan B. Moreno-Cruz, David W. Keith

It appears to be technically feasible to engineer an increase in albedo, a planetary brightening, as a means to offset the warming caused by carbon dioxide (CO2) and other greenhouse gases through Solar Radiation Management (SRM). This option has two characteristics that make it attractive for managing climate risk: it is quick and cheap. However, SRM cannot exactly compensate for the CO2-driven climate change. Moreover, SRM introduces risks in the climate system that are unique to this type of intervention.We introduce SRM in a model of climate change economics and analyze the optimal policy under uncertainty. We find that the …
Mitigation And The Geoengineering Threat, Juan B. Moreno-Cruz
Mitigation And The Geoengineering Threat, Juan B. Moreno-Cruz
Juan B. Moreno-Cruz
Recent scientific advances have introduced the possibility of engineering the climate system to lower ambient temperatures without lowering greenhouse gas concentrations. This possibility has created an intense debate given the ethical, moral and scientific questions it raises. In this paper I examine the economic issues introduced when geoengineering becomes available in a standard two-period two-country model where strategic interaction leads to suboptimal mitigation. Geoengineering introduces the possibility of technical substitution away from mitigation, but it also affects the strategic interaction across countries: mitigation decisions made in the first period directly affect the geoengineering decisions made in the second period. With …
