Peter Kalmus is a climate scientist at NASA's Jet Propulsion Laboratory. At work, he studies the physics of clouds in a changing climate, and at home he explores how we can address climate change while living happier, more connected lives. He lives in Altadena, California with his wife and two children and uses about 1/10th the fossil fuels of the American average.
