This week we're running a series of interviews called Bearing Witness: Voices of Climate Change. They're stories told by longtime Arizonans about changes they've seen in the familiar landscapes of their lives. While personal experience, in and of itself, is not scientific conclusion, many researchers believe long-term observation is a critical component to understanding how climage change affects humanity and the planet. Today, we hear from artist Shonto Begay, who paints unique landscapes of his home on the Navajo Nation. He says climate and weather patterns there used to be well-defined. But now, watering holes once brimming with rain are filled with sand, and Begay says he can no longer smell storms coming. His art reflects the changing climate of his beloved home.
