Nathaniel is a graduate student studying the physics of climate in the Earth and Planetary Science department at UC Berkeley. Prior to graduate school, he earned a B.Sc. in Mathematical Physics from Brown University and investigated ocean fluid dynamics as a researcher in Princeton University’s Department of Geosciences. He has broad interests in understanding how the climate changes from human activity, including carbon emissions and nuclear war. He is researching if historical carbon emissions commit us to future warming, and if firestorms ignited by acts of nuclear war could trigger severe global cooling.
