Abstract. Stratospheric sulfate geoengineering could impact the terrestrial
carbon cycle by enhancing the carbon sink. With an 8 Tg yr−1 injection of SO2 to
produce a stratospheric aerosol cloud to balance anthropogenic radiative
forcing from the Representative Concentration Pathway 6.0 (RCP6.0) scenario,
we conducted climate model simulations with the Community Earth System
Model – the Community Atmospheric Model 4 fully coupled to tropospheric and
stratospheric chemistry (CAM4–chem).
