Raymond Pierrehumbert

Raymond T. Pierrehumbert is the Professor of Planetary Physics at the University of Oxford, having previously served on the faculties of University of Chicago, Princeton, and M.I.T. His work embraces both theoretical fluid dynamics and physics of planetary climate, with the latter including work on global change, deep-time Earth paleoclimate, climate of Solar System planets and climate of exoplanets. He was a lead author of the IPCC Third Assessment report, and has been a co-author of numerous U.S. National Research Council reports, including reports on abrupt climate change, climate stabilization targets, and climate interventions. He is a Fellow of the American Academy of Arts and Sciences, the American Geophysical Union, and the Royal Society. He was awarded an honorary doctorate in environmental science by Stockholm University, and has been named Chevalier de l’Ordre des Palmes Academiques by the Republic of France for his work on climate physics. He was awarded the 2022 Royal Society Rumford medal and the 2025 Jean Dominique Cassini Medal of the European Geoscience Union. Pierrehumbert is the author of the highly regarded textbook, Principles of Planetary Climate (Cambridge University Press), and recently published Planetary Systems: A Very Short Introduction (Oxford University Press).
