Workshop Report on Solar Radiation Modification Research

This document is a workshop report detailing discussions from an EDF-sponsored workshop held in Washington, DC, on February 5-6, 2025, focused on solar radiation modification (SRM) and its potential impacts. The workshop brought together 22 scientists from various fields, including agriculture and hydrology, to explore empirical datasets that could inform SRM impact research. The report outlines the motivation behind SRM, which aims to lower global temperatures by reducing incoming radiation, while also addressing the need for empirical data to understand its broader effects on precipitation, ecosystems, and agriculture. Participants discussed historical analogs, such as volcanic eruptions, to provide context for SRM impacts. Key themes included the importance of agricultural impacts, the effects of stratospheric aerosol injection on light ratios, and the limitations of historical analogs. The report summarizes the discussions and identifies research priorities to enhance understanding of SRM's implications for climate change and agricultural productivity.
