Scientific advisory for Solar Radiation Modification 

 

The University is engaging with Stardust, an organisation developing sunlight reflection technology. Beginning in early 2026, the project aims to advance modelling capability on stratospheric aerosol injection.

Academics, Professors Piers Forster and Dan Marsh, supported by a wider research team, will work with Stardust on a study to quantify how particle choice and injection strategy influence stratospheric chemistry, transport, radiative forcing and climate response, using the Whole Atmosphere Community Climate Model (WACCM) to simulate these processes. 

The goal of this project is to rigorously test hypotheses and generate evidence on the effectiveness and impacts of sunlight reflection technology. 

 Data and findings from the project will be made openly available including publishing both positive and negative results

The research aims to support policymakers by providing evidence for future governance discussions associated with development of Solar Radiation Modification (SRM) technology. The scientific community, including assessments by the Intergovernmental Panel on Climate Change (IPCC), is clear that Solar Radiation Modification  is not a substitute for reducing emissions.

While some SRM approaches may have the potential to limit warming, they are associated with significant uncertainties, risks, and wider social and governance challenges. This research project looks to explore these uncertainties and provide more informed and transparent scientific evidence to guide future thinking.
