Andrew Dessler is a tenured professor of Atmospheric Sciences at Texas A&M and a climate scientist who studies both the science and politics of climate change. His scientific research revolves around climate feedbacks, in particular how water vapor and clouds act to amplify warming from the carbon dioxide that humans emit. In 2012, he received the American Geophysical Union’s Ascent Award from the atmospheric sciences section to reward exceptional achievement by a mid-career scientist. During the last year of the Clinton Administration, he served as a senior policy analyst in the White House Office of Science and Technology Policy. Based on his research and policy experience, he has authored two books on climate change: “The Science and Politics of Global Climate Change: A Guide to the Debate” and “Introduction to Modern Climate Change.” This latter book won the 2014 American Meteorological Society Louis J. Battan Author's Award. In recognition of his work on outreach, in 2011 he was named a Google Science Communication Fellow.
