Kravitz, Ben; Robock, Alan; et al. (2012): Sensitivity of stratospheric geoengineering with black carbon to aerosol size and altitude of injection

Kravitz, Ben; Robock, Alan; Shindell, Drew T.; Miller, Mark A. (2012): Sensitivity of stratospheric geoengineering with black carbon to aerosol size and altitude of injection. In: J. Geophys. Res 117 (D9), pp. 1–22. doi:10.1029/2011JD017341

"Simulations of stratospheric geoengineering with black carbon (BC) aerosols using a general circulation model with fixed sea surface temperatures show that the climate a general circulation model with fixed sea surface temperatures effects strongly depend on aerosol size and altitude of injection."

Schmidt, H.; Alterskjær, K.; et al. (2012): Solar irradiance reduction to counteract radiative forcing from a quadrupling of CO2

Schmidt, H.; Alterskjær, K.; Bou Karam, D.; Boucher, O.; Jones, A.; Kristjánsson, J. E. et al. (2012): Solar irradiance reduction to counteract radiative forcing from a quadrupling of CO2: climate responses simulated by four earth system models. In: Earth Syst. Dynam. 3 (1), pp. 63–78. doi:10.5194/esd-3-63-2012

"In this study we compare the response of four state-of-the-art Earth system models to climate engineering under scenario G1 of two model intercomparison projects: GeoMIP (Geoengineering Model Intercomparison Project) and IMPLICC (EU project "Implications and risks of engineering solar radiation to limit climate change"). [...] Precipitation responses are, however, in many regions of comparable magnitude but globally of opposite sign."
