AGU 100 Fall Meeting 9-13 December 2019: Geoengineering

GC33G - Solar Geoengineering Benefits and Risks: Modeling, Impacts, Analogues, Engineering, Ethics, and Governance II Posters

With continued unabated increase of greenhouse gas emissions, it is increasingly unlikely that climate change can be limited to prevent significant impacts on society and the ecosystem. Therefore, interest in potential geoengineering schemes is increasing, including solar radiation management (SRM) methods. In this session, we invite abstracts that analyze benefits and side effects of different SRM approaches from global to local scales. We encourage studies that explore results from the Geoengineering Model Intercomparison Project, the Geoengineering Large Ensemble project, in particular abstracts from underrepresented groups and developing countries, including studies by the Developing Country Impacts Modelling Analysis for SRM (DECIMALS) project. We further invite studies of analogs such as volcanic eruptions and ship tracks, presentations on process scale models, including effects on agriculture, ecosystems and the economy; development of technology; and governance and ethical aspects of SRM applications.
