Andrew Dessler
Andrew Emory Dessler (born 1964) is a climate scientist. He is Professor of Atmospheric Sciences and Director of the Texas Center for Extreme Weather. His research subject areas include climate impacts, global climate physics, atmospheric chemistry, climate change and climate change policy.
Dessler was born in 1964, in Houston, Texas.[citation needed] He received a B.A. in physics from Rice University in 1986 and an M.A. and Ph.D. in chemistry from Harvard University in 1990 and 1994. His doctoral thesis was titled In situ stratospheric ozone measurements.
After receiving a Ph.D. in 1994 from Rice University, Dessler did two years of Postdoctoral research at NASA's Goddard Space Flight Center and then spent nine years on the research faculty of the University of Maryland from 1996 to 2005. Dessler went on to become an Associate Professor of Atmospheric Sciences at Texas A&M University from 2005 to 2007 and has been a tenured Professor of Atmospheric Sciences there since 2007. Since 2022, he has been the Director of the Texas Center Extreme Weather, formerly the Texas Center for Climate Studies.
In 2004, The New York Times said the results of his 2004 article in the Journal of Climate written with Ken Minschwaner placed them, "in the middle between the skeptics and those who argue that warming caused by burning of fossil fuels could be extremely severe." The authors subsequently wrote a joint letter to the editor in response objecting to the impression given by the article that their "research goes against the consensus scientific view that global warming is a serious concern."
Later research, published in a 2009 article in Science showed "warming from rising carbon dioxide should also lead to increased water vapor and additional warming, doubling the warming effect of the carbon dioxide." according to Kenneth Chang of The New York Times.
In 2011, an article in The New York Times examining the theory that clouds might offset the effects of increased greenhouse gasses found that his analysis in a 2011 article in Geophysical Research Letters "offered some evidence that clouds will exacerbate the long-term planetary warming" Following the publication of the article "Dessler became a target of climate science critics" and was interviewed on the PBS show Frontline for the episode "Climate of Doubt" which explored "the massive shift in public opinion on climate change." As a visiting fellow at the Cooperative Institute for Research in Environmental Sciences in 2013 and 2014 he is undertaking a project titled, "Understanding long-term variations in stratospheric water vapor." In a November 2013 article in the Proceedings of the National Academy of Sciences of the United States of America Dessler and colleagues provide observational evidence of a positive feedback effect of stratospheric water vapor and global warming.
Dessler was a policy analyst in the White House Office of Science and Technology Policy for the final year of the Clinton administration. On January 16, 2014 he testified before the US Senate Committee on Environment and Public Works. Dessler has written op-eds on climate change, and has been consulted by newspapers and has given talks on climate change and government policy.
On July 29, 2025, the United States Department of Energy (DOE) released a report entitled A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate prepared by its newly-formed Climate Working Group, which consisted of five scientists hand-picked by the Trump administration for their longstanding and vocal contrarian views of climate change. On the same day it was released, the report was cited in the Environmental Protection Agency's (EPA) announcement that was seeking to rescind its 2009 Endangerment Finding, which had concluded that greenhouse gas emissions pose a threat to public health, and which underpins the U.S. government's legal authority to combat climate change.
