"We take a systemic and synthesizing view of some of the (inter)disciplinary methods by which these futures are derived: climate and integrated assessment modeling, ‘deductive’ modes of social science inquiry, deliberative stakeholder engagement, and foresight-based scenarios. We speak to the epistemologies, objectives, and user communities surrounding these research practices, highlighting that different modes of constructing and interpreting evidence about an unformed future yield different kinds of results and signals for actions to be taken. We show how different methods for exploring ‘futures’ form an evolving history of how the risks of CE have been assessed (or constructed), and conclude by echoing calls for a stronger shared understanding of the practices and politics that underpin future-oriented research."

"While solar geoengineering could limit some harmful climate impacts, these approaches could also have adverse impacts and would not address the root cause of climate change: rising emissions of heat-trapping gases from burning fossil fuels – or some of the resulting impacts, such as ocean acidification. We also know very little about how it could impact regional weather patterns, global politics, and efforts to curb global warming emissions."
