Solar Radiation Management (SRM) refers to climate intervention technologies which propose to temporarily modify Earth’s radiative budget to offset climate risks associated with climate change. These include stratospheric aerosol injection (SAI), marine cloud brightening (MCB), and cirrus cloud thinning (CCT), among others. In all cases, the tightly coupled complex interplay between chemistry, radiation and dynamics especially with respect to aerosol-cloud interactions, make the regional and global impacts of these proposals highly uncertain. These uncertainties cascade into assessment of human and ecosystem relevant impacts, including but not limited to our understanding of the agricultural, ecological, or socio-political ramifications of large-scale adoption.

This session focuses on advances in the natural science of climate intervention which seeks to identify or reduce sources of uncertainty related to SRM. This may include climate modeling studies, idealized process investigations, experimental results, or observations of natural analogues. We welcome submissions from across the natural sciences as well as the social sciences, including impacts assessment or governance related to SRM strategies. We are particularly interested in work which focuses on understanding and constraining uncertainty related to regions or communities that are especially vulnerable to climate change, and we encourage early career or new members of the research community to consider applying.
