Colorado Drought Conference (start time 4:35): Experts are meeting at a conference in Denver this week to discuss the implications of prolonged drought conditions here in Colorado. How On Earth’ Susan Moran speaks with biologist Dr. Chad McNutt of the NOAA’s National Integrated Drought Information Center about wthe drought means for the ecosystem, and for Western cities — and how we can start to address the problem.

A More Perfect Heaven (start time 11:50): Joel Parker speaks with Dava Sobel, a science journalist and author who tells the stories of the science and the scientists from the past and how they connect to the present. Those stories reveal that the course of scientific progress is far from orderly — it often takes unplanned twists, has failures that require going back and starting over, and can be driven by the quirks of the personalities of individual scientists.

Today we hear about Sobel’s most recent book, A More Perfect Heaven: How Copernicus Revolutionized the Cosmos.  This book also contains the play And The Sun Stood Still, which will be presented in a free staged reading by the Boulder Ensemble Theatre Company this Thursday, September 20th at 6:30 at the Dairy Center for the Arts.

Hosts: Ted Burnham, Joel Parker
