Dr. Ralph Keeling will speak on the iconic “Keeling curve”. This is the continuous measurement record of carbon dioxide concentrations in the atmosphere, initiated at Mauna Loa, Hawaii in 1958 by his father Charles D. Keeling of the Scripps Institution of Oceanography. Dr. Keeling will show the consequences of the years of burning fossil fuels spread across the globe by the circulation of the winds. Dr. Ralph Keeling is professor of geochemistry in the Geosciences Research Division of Scripps Institution of Oceanography, University of California, San Diego. His research focuses on atmospheric composition, the carbon cycle, and climate change. He received his BS in physics, summa cum laude, from Yale University, and a PhD in applied physics from Harvard University. Dr.Keeling completed postdoctoral fellowships at Harvard and the National Center for Atmospheric Research and also served as a visiting scientist at the NCAR. He has received many awards, authored more than 65 research papers and is a member of the American Geophysical Union.
Artist Ruth Wallen will speak and present a slide show about the impact that the buildup of excess CO2 has on the “breathing” of our forests and other ecosystems. Her works, in various artistic media, are in public and virtual spaces as well as galleries. She is on the faculty at Goddard College and a lecturer at the University of California, San Diego. Ms. Wallen earned her BA (with distinction) in Environmental Science, Swarthmore College, her MFA in Visual Arts from University of California, San Diego and was a Fulbright Scholar at the Autonomous University of Baja California, Tijuana.
