(Conversation recorded on September 25th, 2024)   There has been much discussion lately of Planetary Boundaries – the 9 biophysical systems and processes that regulate the functioning of life support systems on Earth, and ultimately the stability and resilience of the Earth system as a whole. But how close are we, today, to pushing these systems past their ability to function and recover?  In this special release episode, Nate is joined by Kari Stoever, Chief of Strategic Partnerships & Policy at the Planetary Boundary Initiative, to explore the answer to this difficult but vital question. They delve into the Planetary Health Check, an annual analysis of Earth's nine Planetary Boundaries, exploring the science behind the metrics as well as aspirations for the project's future in guiding us back toward a safe operating space for Earth.  How could a real-time assessment of the health of our planetary home help us prioritize taking care of it? What are we able to measure, and what do we still need to learn to best inform our policies and actions for the future? What would it take for each of us to act as Planetary Guardians to safeguard our planetary home before it’s too late?   About Kari Stoever: Kari Stoever is a seasoned social entrepreneur and strategist with extensive experience in global health, development, international relations, and planetary health.
