SAM webinar - Solar radiation modification: What are the technologies, and what are the risks?

This webinar, held on 11th March, considered the options on SRM technologies and potential impacts. Following the Scientific Advice Mechanism’s recent reports on Solar radiation modification, we have held a series of webinars considering the issues around SRM. In the third webinar of the series, we examined the options on SRM technologies, the potential risks and impacts, and the prerequisites for possible deployment. It was attended by nearly 100 participants. Key points Dr Simone Tilmes provided background by looking into why SRM is being researched, what the proposed technologies are, along with potential scenarios and strategies for the use of SRM Dr Gabriel Chiodo looked at one SRM technology option, stratospheric injection (SAI), its potential effects and limitations Professor Johannes Quaas examined another option, cloud brightening, as well as limited-area SRM. He considered the prerequisites related to modelling, detection and monitoring. The Deputy Chair of the Group of Chief Scientific Advisors, Professor Naki Nakicenovic, outlined the policy recommendations made by the Group in its Scientific Opinion, particularly as they relate to technologies and possible deployment. Dušan Chrenek, Principal Adviser at DG CLIMA at the European Commission, gave his response to the presentations. There was very lively discussion through the online ‘Chat’ between a highly engaged audience and members of the panel.
