Statement from Frank Keutsch, Principal Investigator of SCoPEx and Stonington Professor of Engineering and Atmospheric Science, Harvard John A. Paulson School of Engineering and Applied Sciences, Department of Chemistry and Chemical Biology and Department of Earth and Planetary Sciences:

"We understand that there are complex societal and governance issues surrounding solar geoengineering and SCoPEx. It's why we have taken extraordinary steps to try to perform the experiment in a manner that exemplifies good governance, implementing an unprecedented level of transparency and recruiting a highly qualified, independent, external committee to provide advice that we have and will continue to take very seriously.

We all realize this is a great learning process, so we and the Committee are doing everything possible to make sure there are opportunities for people to provide comments and constructive criticism. Such input will help the Committee be in the best position possible to weigh whether or not we should proceed with the experiment. We therefore encourage you to provide feedback on their proposed Societal Engagement Process.

I want to thank the SCoPEx Advisory Committee for all of their work thus far. It's exciting to see their new Societal Engagement Process released.

I am also incredibly thankful for the time, energy, wisdom, and dedication that Dr. Louise Bedsworth volunteered as Chair of the SCoPEx Advisory Committee. She has played an invaluable role in our governance process and has helped advance critical pieces of work. Their newly proposed Societal Engagement Process is one recent example, and I very much appreciate their advice on this front. The governance of SCoPEx has always been as central as the science, and we are very fortunate to have had Dr. Bedsworth's leadership and thoughtful approach in this process. I look forward to our continuing work with the Committee, and I sincerely thank all of the members for their important engagement."

Statement from Rick McCullough, Harvard Vice Provost for Research:

"I would like to sincerely thank Louise Bedsworth for leading the SCoPEx Advisory Committee. From the beginning, I have appreciated her thoughtfulness and unwavering commitment as she has worked to develop a governance process that will not only be valuable to SCoPEx, but will also be a model for others. We are grateful for her service, and are excited about the foundation that she and the Committee have already helped build. I look forward to our continuing work with the Committee, and I sincerely thank all of the members for their important engagement."
