Thesis Title Risks to global water resources from geoengineering the climate with solar radiation management
Thesis Abstract Global warming poses grave risks for society and ecosystems. To date, mitigation efforts have been insufficient to prevent greenhouse gas emissions from continuing to rise. Solar radiation management geoengineering has been proposed as a means to slow or reverse global warming by reflecting incoming sunlight back to space. Solar radiation management is receiving growing attention as a potential response to global warming, however its risks are currently unknown. For example, lowering global temperatures with solar radiation management would significantly reduce rainfall in some regions, potentially pushing them into water stress. A global-scale assessment is urgently needed to quantify the risks and opportunities that solar radiation management poses to global water resources. This project will explore this by applying simulations from the latest geoengineering climate model experiments run in the Geoengineering Model Intercomparison Project (GeoMIP) to a global hydrological model. Spatial patterns of rainfall, flood risk, drought, and water stress, across the globe, will be investigated under a set of scenarios of solar radiation management deployment. Uncertainty in model projections will also be examined. The project will answer policy-relevant research questions such as: which parts of the globe will benefit/suffer from solar radiation management; which regions would be better off with global warming than with a cooler climate achieved by geoengineering; and how long would it take for such changes to occur; all within the context of global water resources.
