Daniele Visioni

Daniele Visioni, Ph.D., is an Assistant Professor of Earth and Atmospheric Sciences at Cornell University. His scientific interest is in the interactions between stratospheric aerosols, chemistry and dynamics in the stratosphere and surface climate, including biosphere interactions: he mostly researches this in the context of explosive volcanic eruptions and of Sunlight Reflection Methods (SRM, geoengineering or Climate Intervention). His research interest in SRM has led him to be involved in multiple research endeavors that connect climate modeling with societal, political and ethical issues around this topic, in particular related to the perceived legitimacy of climate scenarios as used to assess SRM, reliability of climate models and how to improve diversity in the field. He also has strong ties with research groups in developing countries through the DEGREES initiative for which he is a volunteer scientific advisor, with the aim of strengthening the voice of scientists in the Global South in discussions around the topic of Climate Intervention.

He uses a wide range of climate models of different complexities to better understand how well the current generation of Earth System Models used in international assessments are at reproducing the complex interactions between middle atmosphere and surface climate. He is also the co-chair of the Whole Atmosphere Working Group for the Community Earth System Model (CESM), which allows him to explore CESM aerosol-climate interaction in depth, and is involved in projects aiming to improve aerosol microphysics in CESM and other models. His role as the GeoMIP cochair also allows him the opportunity to work with multiple groups around the world interested to understand downstream impacts of climate change and of SRM, such as on fisheries, biodiversity and human health.
