Tipping Points: The Geochemistry of the Earth
Talking about feedbacks and interactions that sustain the global aquatic ecosystem including the tipping points towards aquatic ecosystem collapse, including the chemistry and mechanics of the Earth’s underground geology. We will explore Catherine’s research into the Earth’s mantle and crust. What can we learn from the intersection of geology and chemistry?

Aired Saturday, May 6, 2023
The Anthropocene: The Complex Co-evolution of Climate and Life on Earth
Talking about the long view of climate change and evolution while also focusing on defining moments in Earth history where critical thresholds and events have occurred. We will look at the pressures on the hydrologic cycle due to human activity, the effects of industrialization on water availability, quality, and scarcity.

Rivers in the Anthropocene: The History and Current State of Our Nations Rivers
Aired Saturday, April 29, 2023
Rivers in the Anthropocene: The History and Current State of Our Nations Rivers
Talking about the history of the current epoch: the Anthropocene and why we should care about our rivers and streams. We will provide a starting point for a series of conversations about water and the ways in which humans have had an impact as well as ways they can restore, repair, and protect our rivers.
