Raymond Pierrehumbert

Raymond Thomas Pierrehumbert is the Halley Professor of Physics at the University of Oxford and previously served as the Louis Block Professor in Geophysical Sciences at the University of Chicago. He has contributed significantly to climate science, including serving as a lead author on the Third Assessment Report of the IPCC and co-authoring the National Research Council report on abrupt climate change.

Pierrehumbert earned a B.A. in physics from Harvard College and a Ph.D. in aeronautics and astronautics from MIT. He has received several honors, including a John Simon Guggenheim Fellowship in 1996, which supported his research on the climate of early Mars. He is a Fellow of the American Geophysical Union, Chevalier de l'Ordre des Palmes Académiques from France, and was elected to the American Academy of Arts and Sciences in 2015. In 2020, he became a Fellow of the Royal Society.

His research focuses on understanding climate systems through mathematical models, including work on the faint young sun paradox. He is also known for his critiques of solar geoengineering and his contributions to studying exoplanet climates. Pierrehumbert is married to Janet Pierrehumbert, a professor of Language Modeling at Oxford University.

Pierrehumbert has authored numerous papers on topics such as climate dynamics, glacial flow, and planetary energy balance. His work has been published in journals like *Nature* and *Science*, addressing key questions in climate science.
