"But discussion of carbon removal approaches must not be merely technical, but explicitly political. There are two reasons for this. First, the default approach to carbon removal under existing power structures both (a) risks further harm to frontline communities and ecosystems; and (b) probably won’t remove climate-significant amounts of carbon."

‌"Stratospheric aerosol injection (SAI) is one proposed method, reliant on lofting material into the stratosphere. Engineering reviews related to this technology approach have been sparse, with most major primary analyses now at least five years old. We attempt to bridge this gap—with a short, qualitative review of recent developments in various fields of engineering that have potential applicability to SAI."
