Call for Participation: Ocean Visions working groups to advance ocean-based carbon dioxide removal

Deadline: 21. August 2020 "We are looking for motivated individuals from diverse backgrounds to contribute to multi-stakeholder virtual working groups in Fall 2020. These working groups will be oriented around key ocean-based CDR pathways, as well as cross-cutting issues that affect all ocean-based CDR pathways. If you are interested in participating in one or more working groups, please sign up with the survey below by August 21." LINK

Lee, Walker; MacMartin, Douglas; Visioni, Daniele; Kravitz, Ben (2020): Expanding the Design Space of Stratospheric Aerosol Geoengineering to Include Precipitation-Based Objectives and Explore Trade-offs. In Earth Syst. Dynam. DOI: 10.5194/esd-2020-58. "In this study, we first introduce a new method of visualizing the design space in which desired climate outcomes are represented by 2-D surfaces on a 3-D graph." LINK

Janssens, M.; et al. (2020): A specialised delivery system for stratospheric sulphate aerosols: design and operation

Janssens, M.; Vries, I. E. de; Hulshoff, S. J. (2020): A specialised delivery system for stratospheric sulphate aerosols: design and operation. In Climatic Change. DOI: 10.1007/s10584-020-02740-3. "Yet, their technical design characteristics, financial cost of deployment, and emissions have yet to be studied in detail. Therefore, these topics are examined in this two- part study. This first part outlines a set of injection scenarios and proposes a detailed, feasible aircraft design. Part 2 considers the resulting financial cost and equivalent CO2 emissions spanned by the scenarios and aircraft. " LINK
