Limiting warming to levels that avoid extreme risk (1.5 - 2°C) will require removing multiple gigatons of carbon dioxide from the atmosphere each year, on top of immediate and substantial reductions of greenhouse emissions (SR1.5: IPCC, 2018).
Two linked OCB activities designed to marshal the ocean biogeochemistry community to set priorities in marine carbon dioxide removal (mCDR): a workshop designed to both educate and challenge our colleagues to engage mCDR research and and a working group to begin setting benchmarks for problem-solving.
Overall, the aim of the paired workshop and working group is to move beyond calls for more research that identifies unknowns, and transition to solutions-based blueprints and best practices to resolve key issues. One benefit will be a networked international community of practice that can work together to address important interdisciplinary questions in CDR research. Second, this community should go beyond scientific researchers, to include agency and governance voices from the beginning. Ultimately, our research outputs should inform evidence-based decision making, so it will be essential to understand decision points and needs to scale research projects. Including those voices and needs from the outset will help the OCB community accelerate the transition of scientific research to public benefit, an especially important factor given the urgency of this problem.
