LEWISBURG, Pa. — Stephen Pacala, professor of ecology at Princeton University, will give the lecture, "Global Warming and Climate Change: The Reality? The Consequences? The Challenges?" April 6 at 7:30 p.m. in the Rooke Chemistry Auditorium at Bucknell University.

As co-director of the National Oceanic and Atmospheric Administration's Carbon Modeling Consortium and director of Princeton's Environmental Institute, Pacala has explored the problems in a wide variety of ecological and mathematical topics including biodiversity, the mathematics of scaling, ecosystem modeling and ecological statistics.

Most recently he has researched the problems of global climate change with an emphasis on the biological regulation of greenhouse gases and climate.

His work with the NOAA's Carbon Modeling Consortium is to develop a model of the global biosphere that will be used to assess the storage of fossil fuel-derived gases by the atmosphere.

He is the author of more than 120 publications, 27 book chapters, a book, and numerous articles in Nature, Science, PNAS, and Ecology.

This talk is particularly timely given the cover story in this week's Time magazine, "Special Report on Global Warming: Be Worried … Be Very Worried," which talks about tipping points and thresholds in the global climate system.

The lecture, which is open to the public without charge, is the second in the Sustainability Lecture Series sponsored by the Bucknell Environmental Center.

The third speaker in the series will be John Ikerd, professor emeritus of economics with the University of Missouri, who will discuss "Is Capitalism Sustainable?" April 13. Ikerd also will participate in a faculty seminar on April 14 at Bucknell.
