Stratospheric Aerosol Injection: Should We Reflect More Sunlight?

Reflecting sunlight would also change the ocean. Dr. Kelsey Roberts explores stratospheric aerosol injection through ocean and marine ecosystem models. The conversation examines possible changes to sea surface temperature, ocean chemistry, net primary production, fisheries, and food webs under different scenarios. It also explains why modeling is useful at this early stage and why the uneven ecological, economic, and social trade-offs belong inside any discussion of solar radiation modification.
