Peter Kalmus

Peter Kalmus is a climate scientist working at NASA’s Jet Propulsion Laboratory (he speaks here on his own behalf, not on behalf of NASA, JPL, or Caltech). 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. His new book, “Being the Change: Live Well and Spark a Climate Revolution” is now available (New Society Publishers, 2017). Peter volunteers with Citizens’ Climate Lobby, a group focused on implementing carbon fee and dividend.
