Briefing: Diamonds are not a geoengineer's best friend: Carbon impurities provide a reality check

Solar geoengineering, which includes strategies like stratospheric aerosol injection (SAI), aims to mitigate climate change by reflecting sunlight to cool the planet.

Recent findings indicate that carbon impurities in diamonds could impact the anticipated efficacy of SAI, suggesting a need for reevaluation of this approach.

As the field progresses, understanding the implications of these impurities will be critical for the design and implementation of effective geoengineering solutions.
