We broadly oppose commercial development solar geoengineering. In our view, a central objective of solar geoengineering research is to develop credible assessments of its risks and efficacy. Credibility depends, in part, on confidence that the risks of solar geoengineering are not concealed, that its effectiveness is not exaggerated. Such credibility can, in our view, be best generated by a transparent multipolar research effort. Where, “transparent,” means open access to the full research process, including raw data, dead ends, and experimental failures. Where “multipolar” means the research is conducted by a diversity of independent entities including research by groups that focus on finding the ways that it will fail....
