Stratospheric Aerosol Injection: A Geoengineering Strategy's Uncertain Future Amidst Carbon Impurities and Volcanic Precedents
Original framing: “Diamonds are not a geoengineer's best friend: Carbon impurities provide a reality check” — Phys.org
The article grounds its argument in scientific uncertainty, citing the role of carbon impurities in diamonds and the complex chemistry of stratospheric aerosols. It references peer‑reviewed modeling of volcanic analogues and highlights gaps in climate‑system feedback knowledge. The reliance on empirical data and methodological critique gives this dimension a strong footing.
The article’s scientific focus on aerosol chemistry and volcanic analogues reveals both the promise and the profound uncertainty of SAI, while its omission of Indigenous, artistic, and marginalized perspectives underscores a systemic blind spot.
Historical and trickster lenses expose how past natural events and ironic metaphors can both inform and destabilize techno‑optimism. By weaving together cross‑cultural humility, future scenario planning, and equity‑centered governance, a more resilient pathway emerges—one that treats climate engineering not as a solitary technical fix but as a socially negotiated, reversible experiment grounded in diverse knowledge systems.
