The profound and intensifying effects of climate change will likely bring significant harm to those vulnerable to the harsher environment to come, human or otherwise. Yet climate debates have so far been dominated by scientists and policymakers, with limited effectiveness in terms of either public communication or political action. Where and how should the humanities and social sciences intervene in order to place the science-policy nexus on more ethically, epistemically, and politically responsible foundations? This project brought together internationally renowned scholars of the philosophy of science and environmental politics with their counterparts at the University of Chicago in order to open up the science-policy relationship. Through a series of workshops, reading groups, roundtable discussions, and public symposia, the project bridged divides and foster interdisciplinary dialogue on a range of issues, from climate modeling to ethical decision-making and democratic participation.
