Talking Points

Recent interactions between the hosts and their guests.

SAI: Should We Reflect More Sunlight to Cool the Earth? with Dr. Kelsey Roberts

Q: What exactly is Stratospheric Aerosol Injection and how is it modeled in climate systems?

SAI is a deliberate, continuous injection of reflective aerosols into the stratosphere to cool the planet, modeled using climate and Earth system models that perturb the atmosphere with aerosols and assess temperature, precipitation, and ocean responses, including ecosystem implications.

SAI: Should We Reflect More Sunlight to Cool the Earth? with Dr. Kelsey Roberts

Q: Could you introduce yourself and tell us a little about your research?

Dr. Roberts describes her background as a marine ecologist, with work spanning marine protected areas, fisheries bycatch, climate-ready fisheries management, and now studying climate interventions and their ecological implications.

mCDR: Can the Ocean Store Our Carbon for Centuries? with Dr. Morgan Raven

Q: What are the main categories or strategies within marine CDR, and how does nature-based MCDR fit into that framework?

The guest explains that MCDR can be divided into inorganic and organic strategies. Inorganic methods accelerate rock weathering and alkalinity processes, while organic methods rely on photosynthesizers to fix CO2 and store it long-term. Nature-based MCDR focuses on protecting and enhancing blue carbon ecosystems to improve their carbon burial function, especially in anoxic environments where storage can be more stable.

mCDR: Can the Ocean Store Our Carbon for Centuries? with Dr. Morgan Raven

Q: Could you introduce yourself and tell us about your work and how you became interested in this field?

Morgan Raven describes herself as an oceanographer and biogeochemist at UC Santa Barbara, with a background in sulfur isotopes and carbon burial, and notes her role as chief science officer for a startup while keeping her professorial duties. She highlights that her curiosity about Earth's carbon cycle and feedbacks led her into marine CDR research and emphasizes the importance of transparency about potential industry ties.

Biocultural Coastal Conservation | Ancestral Tides with Juan Carlos Cruz

Q: Which sea turtle species does the program focus on and why were they chosen?

The program focuses on olive ridley, leatherback, loggerhead, hawksbill, and green turtles due to their ecological importance, cultural significance to Indigenous communities, and because they nest across the working coast from Mexico to Colombia and Suriname.
