View the recorded webcast of the March 23, 2017 lecture—“How do we tell facts from myths about climate change?” featuring University of Minnesota College of Science and Engineering Dean and world-renowned geochemist Samuel B. Mukasa.

About the lecture

In this lecture, Mukasa demonstrated the differences between natural cycles of climate change and the out-of-cycle changes increasingly being attributed to anthropogenic factors. He provided examples of recent changes observed in both equatorial and polar regions and finished with a sober assessment of what the responsible citizen can do to minimize anthropogenic forcing of climate change.

About the speaker

Samuel B. Mukasa is highly regarded for his research in geochemistry, geochronology and petrology. His work on the origin and evolution of rocks in the Bering Sea and Arctic Ocean regions has helped to shed new light on the evolution of continents and has relevance to issues of climate change. He has served as president of the Geochemical Society and in leadership positions for programs at the National Science Foundation and National Academy of Sciences focused on polar climate issues, among many other scientific and professional leadership roles. He is a Fellow of the American Association for the Advancement of Science and the Geological Society of America.


Samuel Mukasa visited the South Pole during a research trip.

Mukasa holds a Ph.D. in geochemistry from the University of California, Santa Barbara, an M.S. in geology from Ohio State University and a B.S. in geology from UNH. He completed a postdoctoral fellowship at Lamont-Doherty Earth Observatory of Columbia University in New York. He also received a D.Sc. honorary degree from Nkumba University, Entebbe, Uganda, in 2008.
