2023 Congressional Solar Geoengineering Report Acknowledges Likely Transboundary Effects

June 27, 2023 | | The Congressional Research Service published a report in May of this year which outlines various geoengineering methods, including stratospheric aerosol injection (SAI), marine cloud brightening (MCB), and cirrus cloud thinning (CCT). Policymakers are interested establishing a governance framework for solar geoengineering (SG).

According to the paper, “The 117th Congress appropriated funds for FY2022 for activities related to SG in the Consolidated Appropriations Act of 2022…These included the preparation of a report by the Office of Science and Technology Policy (OSTP) in conjunction with the National Oceanic and Atmospheric Administration (NOAA) and the National Science Foundation (NSF)…Further, under this legislation OSTP, working with NOAA, the National Aeronautics and Space Administration (NASA), and the Department of Energy (DOE), is tasked to form an interagency working group to manage SG risk and research and to develop a governance framework for publicly funded SG research.”

In addition to acknowledging likely transboundary effects, the report cites the potential for SAI to reduce precipitation as well as potentially having a damaging effect on stratospheric ozone.

Omitted from the report is Mexico’s ban on Solar Geoengineering, health hazards, and the lack of informed public consent for weather and climate modification.
