The Glaciogenic Effect of Aerosols and Its Potential for Mixed-Phase Cloud Thinning

This 25-minute talk explores how aerosols affect ice formation in clouds and their potential application in climate intervention strategies. Learn about the relationship between dust aerosols and cloud phase, as Diego Villanueva presents research findings from 35 years of satellite data showing strong correlations between dust aerosol and ice-to-total frequency in Northern Hemisphere clouds. Understand how this relationship aligns with laboratory measurements of droplet freezing and how immersion freezing of dust aerosol contributes to cloud phase variability. Discover the implications for mixed-phase cloud thinning as a potential climate intervention technique through artificial aerosol injections. Part of the Solar Radiation Management Annual Meeting 2025 hosted by the Simons Foundation.
