Park Williams Discovers History and Science in a Tree Ring


Park Williams studies trees and climate, in particular the causes of drought and the effects of climate change on forests. An assistant research professor at the Lamont-Doherty Earth Observatory, he travels all over—across the western United States, to the Ozark Mountains, to Ethiopia—and drills into trees to discover their past. Using tree rings and other data, he maps out past climate and the trees’ responses. Some of his recent work helped establish a strong connection between warming climate and the increase in wildfires out West.

In this latest in a series of Earth Institute videos, we spoke to him about what he does, what’s important about it, and how his interest in history and environmental science blended into a career. For more in the series, look here.

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
