Simplified results from the numerical simulation of Coupe et al. (2019) showing the predicted consequences of injecting 150 million tons (150 Tg) of black-carbon aerosol (soot) into the stratosphere. (A) Soot concentration over time. hPa—hectoPascal. (B) Depression of global average temperature and precipitation due to solar radiation absorption above the troposphere. (C) Map showing approximate duration of growing season (without frost) following soot injection for the growing season in the year following soot injection.
