| Sunday, March 26  David Walker, Ph.D. Professor, Earth and Environmental Sciences Is the Earth’s Core Leaking? Against probability, the Earth’s liquid metal outer core may be leaking. How this happens is not yet clear. Maybe cooling upsets chemical balances. Perhaps activity in the biosphere produces materials that are corrosive to the core. How do we understand what goes on thousands of miles deeper than any mine? High-pressure chemistry laboratory experiments provide some answers. |
Sunday, April 9  Juerg Matter, Ph.D. Doherty Associate Research Scientist Climate Change Problem: A Permanent Underground Carbon Storage Solution? Enhanced global warming as a result of carbon dioxide emissions from fossil fuel combustion is one of the most significant environmental problems of this century. Juerg Matter will discuss the potential of carbon sequestration as a climate mitigation technology, and will show how rocks in the deep underground can be used to convert carbon dioxide to a stable mineral form. |

| Sunday, April 30  Lynn Sykes, Ph.D. Higgins Professor Emeritus The 100th Anniversary of the San Francisco Earthquake of 1906: What Have We Learned Since Then About the Earth-Quake Process and Prospects for Earthquake Prediction? The Sumatra and Pakistani earthquakes and Hurricane Katrina are reminders of the great damage and loss of life that can accompany natural disasters. The anniversary of the damaging San Francisco shock of April 1906 is an opportunity to examine progress that has been made in understanding earthquakes and what critical knowledge is still elusive. |
Sunday, May 21  John Mutter, Ph.D. Professor, Earth and Environmental Sciences The Katrina Disaster: A Poor World Tragedy in a Rich Country The impact of natural disasters varies considerably between rich and poor countries with greater numbers of fatalities associated with the latter. These disparities are a result of the interplay between natural and socialfactors. The ensuing devastation caused by Hurricane Katrina in the U.S., however, bears the tragic hallmarks of a “poor world” disaster. John Mutter explains why. This lecture is sponsored by the Lamont-Doherty Alumni Association. |
