Astrobiologist David Grinspoon visited the University of Iowa campus to deliver a lecture in the Creative Matters series sponsored by the UI Office of the Vice President for Research. Below are stories, text, video, photos, and other materials chronicling and related to the visit.

David Grinspoon describes a taxonomy of planetary catastrophes meant to illuminate the unusual nature of the “Anthropocene,” our current time of human-driven planetary changes, and reframes our environmental predicaments as part of a larger narrative of planetary evolution.
