Andrew Dessler is a climate scientist who studies both the science and politics of climate change. He is a Professor of Atmospheric Sciences and director of Texas A&M’s Texas Center for Climate Studies.

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. He is also interested in the intersection of climate change and human society, with the goal of helping us better cope with the impacts of climate change. This includes work quantifying climate extremes and how climate change can alter them, as well as analyzing how climate change will stress crucial energy, water, and other infrastructure and human systems.
