Peter Kalmus is a climate scientist working at NASA’s Jet Propulsion Laboratory. He has a PhD in physics from Columbia University and a BA in physics from Harvard.

At work, Peter uses satellite data, in situ data, and models to study the rapidly changing Earth, with a focus on boundary layer clouds. At home, he explores how dramatically reducing carbon emissions can lead to a happier, more connected life. He enjoys orcharding, beekeeping, and backpacking with his family.
