Global climate change, which is almost universally accepted in the scientific community, may have profound effects on this planet's civilizations. Dr. Charles F. Kennel, a member of the National Academy of Sciences, directed NASA's "Mission to Planet Earth," a study of natural and human-induced changes to the planet. The experience led him to dedicate his research to environmental science, and he subsequently served as the Director of the Scripps Institution of Oceanography and as the Vice Chancellor of Marine Sciences at the University of California, San Diego. He is the founding director of the UCSD Environment and Sustainability Initiative and leads the University of Cambridge/UCSD Global Water Initiative. He will discuss the most current timelines and predictions for a changing climate, and explain actions and adaptations necessary to confront this truly global crisis on Wednesday, September 18 at the University of Maryland. All are welcome, and students are particularly encouraged to attend. Refreshments will be served at 4 pm in the Physics Lecture Hall (1412). The talk will begin at 4:30 pm.
