Global Warming: What We Know and What We Don't Know
The Earth’s climate is changing. That’s both beyond dispute and nothing new. The important questions are: What’s driving this change? How fast will change occur? What does the future hold? Most public debates are carried out with misinformation and irrational exuberance in order to bend the discussion in one direction or another. So now for something completely different: a dispassionate analysis of what we actually know and what we don't yet know about the Earth's climate.
Join David J. Helfand, Chair, Dept. of Astronomy, Columbia University for an informative discussion on how a planet's temperature is controlled, factors affecting this balance and information gathered from Earth's past climatic history in order to understand Earth's future. The program's goal is to provide proven scientific facts so that the public can make a rational response to the Earth's changing climate.
