The talk will begin with a broad overview of climate science, including the history of the science itself, and what we have learned about the Earth’s climate system through analysis of paleoclimate data, the instrumental record, and, most importantly, the fundamental physics, chemistry, and biology underlying the climate system. Projections of future climates, made using both simple and complex models, will be discussed, with an emphasis on sources of uncertainty together with an assessment of whether and to what extent the level of uncertainty can be reduced. Toward the end of the talk, I will frame the problem of global warming as a problem of risk assessment and management, including the difficulties in dealing with low probability but very high impact events, and I will describe various technical and policy options for dealing with climate change will be described. These include important and exciting opportunities in carbon-free energy sources.
Short biography of the speaker:
Dr. Kerry Emanuel is a professor of meteorology currently working at the Massachusetts Institute of Technology, where he also serves as the co-founding director of the MIT Lorenz Center. He is an elected member of the U.S. National Academy of Sciences, the American Academy of Arts and Sciences, an elected fellow of the American Geophysical Union, and the American Meteorological Society. He is also the recipient of the Carl-Gustaf Rossby Research Medal, the highest scientific achievement award bestowed by the American Meteorological Society. In 2006, he was named one of the Time 100 influential people. His research interests include tropical meteorology and climate, hurricane physics, cumulus convection, the role of clouds, water vapor, and upper-ocean mixing in regulation of climate, and advanced methods of sampling the atmosphere in aid of numerical weather prediction.
Coffee and snacks will be served after the lecture.
