Study published on November 4, 2025, in Environmental Research Letters. Stratospheric aerosol injection (SAI) risks harming wine, coffee, and cacao. Luxury crops depend on stable precipitation and humidity. SAI models tested 1.0 and 1.5°C temperature targets above pre-industrial levels. Only six regions showed reliable SAI benefits. France faces $60B wine revenue loss under SAI. Brazil and Ghana show volatile outcomes. SAI remains speculative, requiring adaptation and global cooperation
