Global Warming Expert And UI Alumnus Hansen To Speak Oct. 26

James E. Hansen, one of the foremost proponents of the science of global warming and a University of Iowa alumnus, will speak on "Dangerous Anthropogenic Interference," how man-made activities are competing with natural effects on climate, at 7:30 p.m. Tuesday, Oct. 26, in Lecture Room 1, Van Allen Hall, Linn St. and Iowa Ave.

The free, public talk is the first lecture in the University of Iowa College of Liberal Arts and Sciences Department of Physics and Astronomy 2004-2005 Distinguished Public Lecture Series.

Hansen, currently heads the NASA Goddard Institute for Space Studies in New York City, a division of Goddard Space Flight Center's Earth Sciences Directorate, Greenbelt, Md. He is best known for his 1980s testimony on climate change before congressional committees that helped raise broad awareness of the global warming issue.

Hansen, who earned a bachelor's degree in physics and mathematics in 1963, a master's degree in astronomy in 1965 and a doctorate in physics in 1967, all from the UI, trained in the Department of Physics and Astronomy in the space science program of Dr. James A. Van Allen. His early research on the properties of clouds of Venus contributed to their identification as sulfuric acid clouds. Since the late 1970s, he has worked on studies and computer simulations of the Earth's climate, for the purpose of understanding the human impact on global climate.

He was elected to the National Academy of Sciences in 1995 and, in 2001, received both the Heinz Award for environment as well as the American Geophysical Union's Roger Revelle Medal.

The Distinguished Public Lecture Series is aimed at providing an introduction to the frontiers of physics and astronomy for non-specialists, including the general public, and will feature prominent speakers from the University of Iowa and other institutions. Future lectures in the series will be announced periodically throughout the 2004-2005 academic year. The series is presented by the Department of Physics and Astronomy, the College of Liberal Arts and Sciences and the Office of the Vice President for Research.

Individuals with disabilities are encouraged to attend all UI-sponsored events. People requiring an accommodation in order to participate in this program are asked to contact in advance the UI College of Liberal Arts and Sciences Department of Physics and Astronomy at 319-335-1686.
