Cloud Chamber bench experiment and modeling, (abstract) “Experimental and modeling results suggest particles will act as the nucleation sites for polar stratospheric cloud ice and, after sedimentation into the troposphere, impact cirrus clouds in the absence of other efficient ice nucleating particles. These results show that an overly…
Summary – “From the geoengineering large ensemble (GLENS). Using a linearized scaling of GLENS we find that halving warming with stratospheric aerosols moderates important climate hazards in almost all regions.” (Abstract) “Here, we test if this result holds for a more realistic representation of stratospheric aerosol geoengineering using…
Stratospheric calcite injection uses micro ground limestone and has similar reflectivity and longevity to sulfate aerosols, but does not deplete stratospheric ozone like sulfates. It actually helps to restore lost stratospheric ozone. from the abstract, ” Injecting sulfate aerosol into the stratosphere, the most frequently analyzed proposal for…
Summary – “If solar geoengineering were used to hold radiative forcing constant under RCP8.5, the carbon burden may be reduced by ~100 GTC, equivalent to 12–26% of twenty-first-century emissions at a cost of under US$0.5 per tCO.” It is also important to note that all other warming related responses…
Report Framework In this paper, a risk-risk tradeoff framework is used to compare a world with SRM and a world without SRM in addressing climate change. The risk-risk tradeoff framework considers the full portfolio or scope of important consequences that may arise from a decision. In this framework,…
