Abstract

Solar climate intervention using stratospheric aerosol injection is a proposed method of reducing global mean temperatures in order to avoid the worst consequences of climate change. A detailed assessment of responses and impacts of such an intervention is needed in order to aid society in decision-making around this topic. We present here a small ensemble of simulations with one of the most comprehensive Earth system models that aims at simulating a plausible deployment of stratospheric aerosol injection to enable community assessment of responses of the Earth system to solar climate intervention. The Assessing Responses and Impacts of Solar climate intervention on the Earth system with stratospheric aerosol injection (ARISE-SAI) simulations utilize a moderate emission scenario, introduce stratospheric aerosol injection at ~ 21 km starting in year 2035, and keep global mean surface air temperature near 1.5 C above the pre-industrial value. We present here the detailed simulation set-up, aerosol injection strategy, and mean surface climate changes associated with this type of intervention, discuss data availability, and ways for the community to get involved in the evaluation of these simulations.
