• How growing up in suburban New Jersey with a science teacher mother shaped his connection to nature and science.
• His move from ecology to forest remote sensing, and how it gives him a unique perspective on forests.
• His passion for paleobotany and early plant evolution.
• His realization that carbon market challenges stem primarily from human factors rather than technical limitations.
• How direct observation of carbon market projects revealed both transformative community benefits and serious human rights violations.
• His pragmatic view of carbon markets as a flawed but necessary climate solution given human nature.

In this episode I speak with Ross Kenyon, former VP of Strategy at Nori, a carbon removal marketplace that recently shut down. We discuss:
• How his humanities background shaped his approach to climate work, bringing a generalist perspective focused on questioning assumptions.
• His engagement with Christianity through Tolstoy's radical interpretation of the Sermon on the Mount.
• Why attributing ecological degradation to Christianity's concept of "dominion" oversimplifies both religious teaching and historical causation.
