Kristina Dahl is a senior climate scientist for the Climate & Energy program at the Union of Concerned Scientists. In her role, she designs, executes, and communicates scientific analyses to make climate change more tangible to the general public, and to policymakers. Her research focuses on the impact of climate change, particularly sea level rise and extreme heat, on people and places. Much of Kristy's work involves spatial analyses and products, reflecting her lifelong passion for maps.

Prior to joining UCS, Dr. Dahl was the associate director of a school-wide climate change initiative at Rutgers University, and provided scientific guidance as a course scientist for the American Museum of Natural History’s Seminars on Science program, a set of online courses geared toward K-12 educators. She also served as a science communicator for Al Gore’s Climate Project, delivering presentations on global warming for K-12 students and adult learners.

Dr. Dahl earned a PhD in paleoclimate from the MIT/Woods Hole Oceanographic Institution Joint Program, and a BA in Earth sciences from Boston University. She has been quoted in BloombergThe Guardian, National Geographic, The New York TimesThe New Republic, San Francisco Chronicle, The Weather Channel, and local news outlets.
