"This raises the specter of geoengineering : issues like seeding the stratosphere with sulfur, or utilizing ice crystals to dissolve heat-trapping clouds. However geoengineering is a grimy phrase many local weather scientists and local weather coverage specialists keep away from, as a result of people meddling with nature does not have one of the best observe document. Which is why they are saying world leaders have to give you some guidelines about geoengineering ASAP, earlier than desperation over the approaching local weather disaster forces humanity to do one thing it’d properly remorse."

Nalam, Aditya; Bala, Govindasamy; Modak, Angshuman (2017): Effects of Arctic geoengineering on precipitation in the tropical monsoon regions. In Clim Dyn 41 (1), p. 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 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 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."

"The Carnegie Climate Geoengineering Governance Initiative is trying to start the debate around geoengineering now so we're ready if and when we need to deploy it."
