An eight-ton concrete ball and a 32,000-year-old needle collection. What's all this got to do with the Arctic? Find out on this episode of Threshold.
Each season, Threshold explores one story from the natural world, and what it says about us. Season two is all about the Arctic: what it is, what's changing there, and why that matters for everybody.
Tune in on Wyoming Public Radio Sundays at 6:00 p.m. to hear the broadcast of Threshold season two.
