Alan Robock, a Rutgers University professor and global climate change researcher, will speak at Northern Michigan University at 8 p.m., Tuesday, April 14, in West Science 2904. Robock's presentation is titled “Global Warming Is Real, and What You Can Do About It.” The presentation is free and open to the public. Robock was a member of the intergovernmental panel on climate change that won the Nobel Peace Prize in 2007. His current research involves several aspects of climate change: geoengineering, regional atmosphere-hydrology modeling, climatic effects of nuclear weapons, soil moisture variations, effects of volcanic eruptions on climate, detection and attribution of human effects on the climate and the impacts of climate change on human activities. Robock, who has published more than 250 articles, served as the state climatologist of Maryland from 1991-97. The NMU chapter of the Sigma XI Research Society is sponsoring the presentation.
