Advances in Solar Radiation Modification (SRM) Research

Session ID#: 159415

Session Description:
Persistent CO2 emission growth casts some doubt over the chance of stabilizing Earth's temperature over the next decades through emission cuts alone. Solar Radiation Modification (SRM, also known as Geoengineering or Climate Intervention) proposes to temporarily modify Earth's radiation budget to reduce the effects of climate change in the near term alongside decarbonization. Common proposed SRM methods include stratospheric aerosol injection (SAI), marine cloud brightening (MCB), cirrus cloud thinning, and surface albedo modification. Climate Intervention governance must be grounded in a solid basis of natural science and engineering research which quantifies the feasibility, risks, and benefits of each proposal. We welcome all contributions focusing on the advancements in natural science of climate engineering, including climate modeling studies, ecological impacts, engineering investigations, experimental results, and analogue observations (e.g. volcanoes, ship tracks).  We also encourage broader scope studies that connect the climatic and ecological impacts with the economic, social, political, or ethical implications of Climate Intervention, and abstracts from underrepresented communities/locations who may be disproportionately affected by climate change.
