On today’s Your Call One Planet Series, I’ll be guest hosting and talking to University of Pennsylvania renowned climate scientist Dr. Michael Mann, presidential distinguished professor in the Department of Earth and Environmental Science and director of the Penn Center for Science, Sustainability, and the Media.

He will discuss his new book, Our Fragile Moment: How Lessons from Earth’s Past Can Help Us Survive the Climate Crisis. In this sweeping work of science and history, Mann shows us the conditions on Earth that allowed humans not only to exist but to thrive, and how they are imperiled if we veer off course.

Then we’ll discuss Water for Life, a documentary film that tells the story of three Indigenous activists in Central and South America, fighting to protect their ancestral lands and water rights.

The film follows Alberto Curamil, a Mapuche chief in Chile; Francisco Pineda, a corn-grower in El Salvador; and the late Berta Cáceres, of the Lenca in Honduras, as they face jail and murder while leading movements to safeguard their drinking water and irrigation water from multinational corporations and corrupt governments. Joining us will be:

• Will Parrinello, award-winning documentary filmmaker and the director of Water for Life
• Sarah Kass, award-winning storyteller specializing in long- and short-form documentaries and non-fiction television, and producer of Water for Life
