The Ridgefield Library and The Discovery Center of Ridgefield present Global Warming: What We Know and What We Don’t Know with Dr. David J. Helfand, from the Department of Astronomy at Columbia University. The program takes place at the library on Thursday, Oct. 5 at 7 p.m.
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? Few public debates are carried out with so much misinformation and irrational exuberance. So now for something completely different: a dispassionate analysis of what we actually know and what we don’t yet know about climate change.
