➡️ Most private funders made their money in the tech sector ➡️ Private money supports awareness and advocacy groups, whereas public funds almost exclusively support research This raises important questions about whose interests are shaping the field of solar geoengineering and its research agenda.

📊 Their study identifies eight recurring rationales for rejecting the development and potential future use of these technologies and shows how this opposition is increasingly coalescing around the language of “non-use”.
