Nathaniel Tarshish

Nathaniel is a climate scientist with broad interests in understanding historical and future global warming.

He received a Ph.D. in Earth and Planetary Science from UC Berkeley in 2024 and earned a B.Sc. in Mathematical Physics from Brown University. As a fellow, he studied the processes behind ocean heat uptake, as well as how past and future emissions shape warming. On future warming, his research demonstrated that net-zero greenhouse gas emissions yield cooling rather than a flat temperature response. On past warming, his work showed that fossil fuels caused net cooling until the 1980s because of the sulfur co-emitted with greenhouse gases. Read more about this work at www.nathanieltarshish.com.

In addition to his research, Nathaniel is invested in outreach and works with Climate Up Close to engage the public through tours and discussions about climate change.
