Earthwatch Radio is produced by staff and students at the Sea Grant Institute at the University of Wisconsin-Madison. We cover a wide range of subjects that concern science and the environment and give special attention to global climate change, the Great Lakes and the oceans. We produce five programs every week and distribute them to more than 120 radio stations and other broadcast outlets, mostly in North America.
