Anthony D. Barnosky is a paleobiologist and global change scientist. His work combines paleontology, biology, and conservation biology in ways that have helped define how people have triggered the onset of the Anthropocene. Currently at Stanford University he is the Executive Director Jasper Ridge Biological Preserve and a Professor of Biology. Prior to that he was on the faculty in Integrative Biology at the University of California Berkeley, where he is a Professor (Emeritus). Author of numerous scientific publications, op eds, blog posts, and books, he has spent more than three decades conducting research related to past planetary changes, and what they mean for forecasting the changes to come on Planet Earth in the next few years. He has worked in South America, India, China, Africa, Europe, and the western USA in a quest to learn how past species reacted to major environmental changes, the state of our planet today, and how we can guide it toward a future we want, rather than one that inadvertently happens to us.
