Climate change is real and is having an impact on one of the most treasured resources in the United States: our National Parks. Park Service Director Jon Jarvis talks about how the environment is changing, and what we can do about it.

National Park Service Director Jonathan B. Jarvis began his career in 1976 as a seasonal interpreter in Washington, D.C. Today, he manages that agency whose mission is to preserve America’s most treasured landscapes and cultural icons.
