Mann’s research focuses on climate variability and extremes, paleoclimate, tropical cyclones, and climate education and policy. In 1999, he and his colleagues produced a reconstruction of temperature changes over the past 1,000 years that demonstrated a pronounced human impact on climate. Described as the “hockey stick” graph because of its dramatic upward curve, the work was for many years a focal point for attacks by climate science skeptics.
In addition to his research, he speaks and writes extensively on climate issues for general audiences, including his most recent book, “The New Climate War”, which examines the role of fossil fuel companies in shaping attitudes on climate change. He is widely recognized for his contributions to climate science communication and is a co-founder of the award-winning science website RealClimate.org. Under his leadership, the new PCSSM will engage expertise from within and beyond Penn to improve the public conversation surrounding issues of environmental sustainability and climate.
Mann is currently Distinguished Professor of Atmospheric Science at Penn State, with joint appointments in the Department of Geosciences and the Earth and Environmental Systems Institute, and is also director of the Penn State Earth System Science Center. He is the author of more than 200 peer-reviewed and edited publications, numerous op-eds and commentaries, and five books. He has been recognized with an array of honors including being named by Scientific American as one of the 50 leading visionaries in science and technology in 2002; receiving the 2019 Tyler Prize for Environmental Achievement, frequently referred to as the Nobel prize for the environment; and being elected in 2020 to the National Academy of Sciences.
Mann is the first new faculty member to be recruited as part of the recently announced Energy and Sustainability Initiative, which is providing resources to bring in 10 new faculty working in such critical areas as diversifying energy sources and storage; enhancing energy efficiency and sustainability; and monitoring, sequestering, and transforming climate-changing pollutants. Steven J. Fluharty, dean of the School of Arts & Sciences and Thomas S. Gates, Jr. Professor of Psychology, Pharmacology, and Neuroscience, says that “Michael Mann has done groundbreaking work on the attribution of extreme weather to climate change and many other aspects of climate science that are of central importance to climate policy. He is also a gifted and fearless communicator, providing patient, clear, and informed explanations even in the most hostile media environments. His appointment will transform Penn’s growing strength in climate science and policy.”
Applying design to agriculture for a new approach to agroforestry

Future mRNA vaccines may prevent food and seasonal allergies
Early research from Penn Medicine finds a new mRNA vaccine stops allergens from causing immune reactions and life-threatening inflammation, with promise for future treatment for a variety of seasonal and food allergies.
Helping robots work together to explore the Moon and Mars
Penn Engineers, NASA, and five other universities tested robotic systems designed to help unmanned explorers cooperate in the dunes of White Sands, New Mexico, paving the way for Moon and Mars exploration.
Deepfakes, digital doubles, and the law: Jennifer Rothman on protecting identity in the AI era
The evolution of AI technology may require more robust copyright laws and guardrails that protect people’s control of their own identities, says the Penn Carey Law professor.
