This interview was recorded on December 16, 2022. Solar radiation modification may one day be needed to reduce climate risks, but great uncertainties remain, and more research and inclusive governance is needed to assess it, says Maarten Van Aalst, during a  C2GTalk. That requires discussions at all levels with people from a range of political and ethical backgrounds, in ways which respect different perspectives. Van Aalst is director general and chief science officer at the Royal Netherlands Meteorological Institute (KNMI), having assumed that role on February 1, 2023. Before that, and at the time of this recording, he was director of the International Red Cross Red Crescent Climate Centre, the reference center on climate risk management for the international Red Cross Red Crescent movement. Van Aalst is also coordinating lead author for the Intergovernmental Panel on Climate Change (IPCC WGII) and member of the European Advisory Board on Climate Change under the European Climate Law.
