The Paris accord (December 2015) signals an international effort to hold global temperature change below 2°C above pre-industrial levels. Since it is unlikely that we can achieve this goal by cutting emissions of greenhouse gases, we are led to ask what role solar climate engineering (SCE) might play in reducing global warming. This presentation briefly reviews the science and available options for reducing absorbed solar radiation in the Earth climate system. It then provides additional detail on marine cloud brightening (MCB) which seeks to reduce absorption by enhancing the reflectivity of low clouds over the ocean. The presentation concludes with an overview of some of the ethical and policy questions associated with climate engineering.
