Daniel Merson Kammen is a Distinguished Professor of Energy in the Energy and Resources Group at the University of California, Berkeley and a former Science Envoy for the State Department.[1][2] He holds a dual appointment at the University's Energy and Resources Group (part of the College of Natural Resources) and the Goldman School of Public Policy. He is also a coordinating lead author for the Intergovernmental Panel on Climate Change, which won the 2007 Nobel Peace Prize for their report, Climate Change 2007, assessing man-made global warming.[3] Kammen was elected a permanent fellow of the African Academy of Sciences in 1998 and, in 2007, received the Distinguished Citizen Award from the Commonwealth Club of California.[3]

On September 9, 2010, Kammen was appointed chief technical specialist for renewable energy and energy efficiency at the World Bank.[4]

In 2016, he was selected as a U.S. Science Envoy by the United States State Department.[5] He resigned from this position in 2017, citing what he believed to be President Trump's failure to denounce white supremacists and neo-Nazis.[2] His August 23, 2017, resignation letter went viral, as netizens noticed that the first letter of each paragraph spelled out I-M-P-E-A-C-H.[6]

Early life and education[edit]

Originally from Ithaca, New York, Kammen is the son of Pulitzer Prize-winning historian and Cornell University professor Michael Kammen.[7] He received his bachelor's degree in physics from Cornell University and his master's degree and PhD in physics from Harvard University.[8] As a postdoctoral researcher at Caltech, Kammen began to transition to energy research, with a focus on the role of energy in developing economies.[9]
