Seminar

Abstract

I will discuss two topics. First, some results on the relative risks of solar geoengineering and carbon removal used to achieve the same temperature reduction. Second, some results and more questions about the engineering of sulfur transport to the stratosphere including questions of which sulfur species and how the choice of species interacts with the formation of aerosols.
