More research and better governance is needed to help developing countries make decisions about solar radiation modification (SRM), says Thelma Krug, vice-chair of the Intergovernmental Panel on Climate Change (IPCC), during a C2GTalk. SRM has come into focus due to a likely overshoot of the 1.5C warming goal, which would bring increasing risks to people and natural ecosystems, and—depending on the length and extent of overshoot—potentially irreversible impacts. Thelma Krug is a former researcher at the Earth Observation Coordination at the National Institute for Space Research in Brazil, under the Ministry of Science, Technology, Innovation and Communication (MCTIC). She was elected vice-chair of the Intergovernmental Panel on Climate Change (IPCC) for the Sixth Cycle of Panel (October 2015 – October 2022), after having been co-chair of the IPCC Task Force on National Greenhouse Gas Inventories from 2002 until 2015.
