Ben is interested in how the climate responds to radiative forcing across a wide variety of spatial and temporal scales. His primary method of investigating climate forcing and feedbacks is through simulations of geoengineering, or deliberate interventions into the climate system to counteract some of the effects of human-induced climate change. He is the coordinator of the Geoengineering Model Intercomparison Project (GeoMIP), a worldwide effort to understand common climate model responses to various geoengineering scenarios.
