Thomas Murphy: “Physics and Planetary Ambitions”

For centuries, modern science has relied on the scientific method to better understand the world around us. While helpful in many contexts, the scientific method is also objective, controlled, and reductionist – often breaking down complex systems into smaller parts for analysis and isolating subjects to test hypotheses. In contrast, indigenous wisdom is deeply contextual, rooted in lived experience, and emphasizes a reciprocal, integrated relationship with the rest of the natural world, viewing all parts of the system as interconnected. What becomes possible when we combine the strengths of each of these knowledge systems as we navigate humanity’s biggest challenges? 

In this episode, Nate interviews Professor Ted Parson about solar geoengineering (specifically stratospheric aerosol injection) as a potential response to severe climate risks. They explore why humanity may need to consider deliberately cooling Earth by spraying reflective particles in the upper atmosphere, how the technology would work, as well as the risks and enormous governance challenges involved. Ted emphasizes the importance of having these difficult conversations now, so that we’re prepared for the wide range of climate possibilities in the future.

Many of us wrestle with the unsettling truth that everyone – including ourselves and those we love – will one day die. Though this awareness is uncomfortable, research suggests that the human capacity to contemplate death is a byproduct of consciousness itself. In fact, our efforts to cope with mortality are at the core of culture, religion, the desire for wealth, and even many of today’s societal crises. How might a deeper understanding of our implicit reactions to mortality help us turn towards responses that are more supportive of our species and planet?
