Arthur Obst

Obst received his PhD in Philosophy from the University of Washington, Seattle, in the Spring of 2023. His research lies at the intersection of traditional environmental philosophy and the ethics of the ongoing climate crisis.

Obst's dissertation clarified the conceptual underpinnings of classical US preservation thought to establish its pressing social and political relevance today. From 2023 to 2025, he served as a Postdoctoral Associate for the Climate Futures Initiative at the High Meadows Environmental Institute and the University Center for Human Values at Princeton University. In this capacity, he served as the primary organizer of "Geoengineering in Crisis: The Princeton Workshop on Geoengineering Ethics and Governance." 

As of September 2025, he is a research fellow at the Climate Systems Engineering initiative at the University of Chicago under the mentorship of Professor Sarah Fredericks. He has been published in Environmental Values and Environmental Ethics, and other journals. He is co-author of Dialogues on Climate Justice with Stephen Gardiner (Routledge, 2023) and co-editor of Environmental Ethics Evolves: A Collaborative Introduction with Linde De Vroey (Routledge, 2027).
