Dr. Henry Pollack, a 1954 graduate of Central, has enjoyed a distinguished academic career in the Department of Geological Sciences at the University of Michigan for over four decades. His undergraduate work was at Cornell University, but he returned to Nebraska for a Master’s degree, went on to Michigan for his PhD, and then to Harvard for post-doctoral research. He has also conducted research at universities in Canada, England and Africa. Dr. Pollack and his colleagues on the Intergovernmental Panel on Climate Change shared the 2007 Nobel Peace Prize with former Vice President Al Gore, and he now serves as a science advisor for Gore’s Climate Project. Other honors include fellowship in the American Association for the Advancement of Science, the Geological Society of America, and the American Geophysical Union, as well as several teaching awards and lectureships in the USA and abroad. His recent book, “Uncertain Science…Uncertain World,” written for a non-scientific audience, addresses current issues such as global climate change in the context of scientific uncertainty. In this book he points out that although uncertainty always obscures understanding, waiting for clarification is often just an excuse for maintaining a dangerous status quo. He argues that policy must be made in an environment of uncertainty, but that mid-course corrections can later accommodate new developments. He believes that uncertainty, rather than hampering problem-solving, actually stimulates creativity and promotes progress.
