In this second e-seminar in a series of nine, professor of geological sciences Paul Olsen explores the beginning of the age of the dinosaurs, the Triassic Period. Discover the kinds of animals that eventually gave rise to the dinosaurs, the earliest dinosaurs, and the organisms that shared the Earth with them—including fierce rivals that dominated the land until a mass extinction cleared the way for dinosaur domination.
In this e-seminar, the first in a series of four, Professor Kelley gives a tour of brain anatomy and shows how nerve cells communicate with one other. She then explores how the fascinating signals of pheromones are used and sensed in the animal kingdom, and whether there is any likelihood that we, too, are lured to one another by odors we can't "smell."
In this second e-seminar of an eight part series, The Normal Environment: The Way Things Are Now, Professor Despommier describes the producer-consumer interactions that drive ecosystems, the types and characteristics of ecoregions of the world, and the often undervalued "free" services (to which he attempts to assign a value) that ecosystems provide for us.
Professor Mark Levy leads an exploration of the many facets of environmental sustainability in this e-seminar, which is taught in conference-style format and features the perspectives of nine Columbia University faculty members associated with the Center International Earth Science Information Network.
A comprehensive searchable database of climate data. It contains a large number of climate models.
At the World Summit on Sustainable Development in Johannesburg in 2002, Columbia University researchers presented scientific advances in critical areas where immediate investment is required to relieve extreme poverty and get ahead of global climate change risks.
Science Learning Tools
At an event sponsored by Columbia's Center for the Study of Science & Religion on April 3, 2002, Manuela Veloso, computer science professor at Carnegie Mellon Universtiy, offers the example of a robotics soccer competition to demonstrate that robots can collaborate and learn.
Leading scientists from Columbia and research universities in Quebec came together for the Quebec-Columbia Nanotechnology Symposium on April 11, 2002, with the intention of forming collaborations on the frontier of nanoscale research in many disciplines and to learn about initiatives and funding in New York and Quebec.
Columbia scientist Surabi Menon says that large amounts of black carbon (soot) particles and other pollutants are causing changes in precipitation and temperatures over China and may be at least partially responsible for the tendency toward increased floods and droughts in those regions over the last several decades.
Lewis Gilbert, executive director for integration and implementation in the Columbia Earth Institute, says that to address its contribution to climate change, the United States must set more aggressive carbon dioxide reduction goals.
