LU Sigma Xi scientific research society chapter hosts climate expert

The Lamar University chapter of Sigma Xi, the Scientific Research Society, will host Bette Otto-Bliesner, a climate expert with the American Meterological Society, in a free public lecture April 19.

Otto-Bliesner is a senior scientist in the Paleoclimate Group in the Climate and Global Dynamics Division at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. She will discuss “Climate Change: What Could Happen and What Can Earth’s Past Tell Us?” at 7:30 p.m. in Room 101 of the Geology Building on the LU campus.

She holds a doctorate in meteorology from the University of Wisconsin-Madison. She worked at the National Center for Atmospheric Research from 1974-1976 and rejoined the center in 1995 after serving on the faculty of the geology department at the University of Texas at Arlington.

Her research interests include using computer-based models of Earth's climate to investigate past climate change and climate variability across a wide range of time. She is particularly interested in climate change forced naturally over the glacial-interglacial cycles of the last million years.

Otto-Bliesner serves on the scientific steering committees for the International Geosphere-Biosphere Programme’s Past Global Changes project and the Paleoclimate Modeling Intercomparison Project. She is a lead author on the chapter on paleoclimate in the United Nations Intergovernmental Panel on Climate Change report issued in 2007. She is a prolific researcher and author of scholarly works on climate modeling.

Founded in 1886 at Cornell University, Sigma Xi has more than 500 chapters in North America and around the world at colleges and universities, industrial research centers and government laboratories. The society has more than 60,000 members worldwide.
