Odoulami, Romaric C.; et al. (2020): Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town

Odoulami, Romaric C.; New, Mark; Wolski, Piotr; Guillemet, Gregory; Pinto, Izidine; Lennard, Christopher et al. (2020): Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town. In Environ. Res. Lett. 15 (12), p. 124007. DOI: 10.1088/1748-9326/abbf13.

"Here, we assess the potential for geoengineering using stratospheric aerosols injection (SAI) to offset the risk of 'Day Zero' level droughts in a high emission future climate using climate model simulations from the Stratospheric Aerosol Geoengineering Large Ensemble Project."

The Conversation: Dimming the sun could reduce future drought risk in Cape Town – but there’s a catch

"Despite a recent slight decline due to the COVID-19 pandemic, greenhouse gas emissions continue to accumulate in the atmosphere. They are projected to rise again once the economy recovers."

Odoulami, Romaric C.; et al. (2020): Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town

Odoulami, Romaric C.; New, Mark; Wolski, Piotr; Guillemet, Gregory; Pinto, Izidine; Lennard, Christopher et al. (2020): Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town. In Environ. Res. Lett. 15 (12), p. 124007. DOI: 10.1088/1748-9326/abbf13.

"Here, we assess the potential for geoengineering using stratospheric aerosols injection (SAI) to offset the risk of 'Day Zero' level droughts in a high emission future climate using climate model simulations from the Stratospheric Aerosol Geoengineering Large Ensemble Project. Our findings suggest that keeping the global mean temperature at 2020 levels through SAI would offset the projected end century risk of 'Day Zero' level droughts by approximately 90%, keeping the risk of such droughts similar to today's level."

Banerjee, Antara; et al. (2020): Robust winter warming over Eurasia under stratospheric sulfate geoengineering – the role of stratospheric dynamics

Banerjee, Antara; Butler, Amy H.; Polvani, Lorenzo M.; Robock, Alan; Simpson, Isla R.; Sun, Lantao (2020): Robust winter warming over Eurasia under stratospheric sulfate geoengineering – the role of stratospheric dynamics. In Atmos. Chem. Phys. Discuss. (in review). DOI: 10.5194/acp-2020-965.

"It has been suggested that increased stratospheric sulfate aerosol loadings following large, low latitude volcanic eruptions can lead to wintertime warming over Eurasia through dynamical stratosphere-troposphere coupling. We here investigate the proposed connection in the context of hypothetical future stratospheric sulfate geoengineering in the Geoengineering Large Ensemble simulations."
