Nalam, Aditya; Bala, Govindasamy; Modak, Angshuman (2017): Effects of Arctic geoengineering on precipitation in the tropical monsoon regions. In Clim Dyn 41 (1), p.[nbsp]1738. DOI: 10.1007/s00382-017-3810-y.

„In this study, we investigate and quantify the implications of this ITCZ shift due to Arctic geoengineering for the global monsoon regions using the Community Atmosphere Model version 4 coupled to a slab ocean model. A doubling of CO₂ from pre-industrial levels leads to a warming of ~6[nbsp]K in the Arctic region and precipitation in the monsoon regions increases by up to ~15%. In our Arctic geoengineering simulation which illustrates a plausible latitudinal distribution of the reduction in sunlight, an addition of sulfate aerosols (11[nbsp]Mt) in the Arctic stratosphere nearly offsets the Arctic warming due to CO₂ doubling but this shifts the ITCZ southward by ~1.5° relative to the pre-industrial climate.“
