Under the joint leadership of the United Nations Environment Programme (UNEP) and the World Metrological Organization (WMO) a hybrid Consultative Workshop and Science Policy Dialogue on Solar Radiation Modification (SRM) will be hosted in Geneva in May 2025. The aim is to foster a shared understanding of the status of SRM science and research and to facilitate Science-Policy dialogues for a collective inquiry on this topic based on the updated science information. The two-day workshop supported by the International Science Council (ISC) and World Climate Research Programme (WCRP) will therefore include knowledge sharing sessions followed by a facilitated Science-Policy Dialogue. The Workshop will bring together key experts, researchers and practitioners working on SRM as well as UNEP Member States and Major Groups of Stakeholders.
