SAI option involves sulfate aerosols (scattering aerosols), not black carbon aerosols or smoke which are absorbing aerosols....I believe BC aerosols in large quantities in the stratosphere would have devastating consequences for stratospheric ozone. Also, there is no ocean fertilization effect from smoke particles. Bala
