Halving warming with stratospheric aerosol geoengineering calcitestratospheric aerosols

Halving warming with stratospheric aerosol geoengineering

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 aerosol injection with calcite restores stratospheric ozone, it does not deplete it like stratospheric sulfate injection

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…

Solar Radiation Modification: A Risk-Risk Analysis, Carnegie Climate Governance Initiative Risk-Risk Analysissolar radiation modification SRM

Solar Radiation Modification: A Risk-Risk Analysis, Carnegie Climate Governance Initiative

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,…
