Science in Perspective
🌌 Science in Perspective
Science in Perspective examines what research actually shows, not what headlines say it shows. Each episode starts from real work and asks what patterns remain when the hype is stripped away. The focus is on the organizing principles that recur across various domains of science, and on why those principles so rarely survive the journey from journal to public conversation.

Cool the World, Wreck the System: The Illusion of Control

In this episode I discuss geoengineering, focusing on the UK’s proposed aerosol project to reflect sunlight and reduce global temperatures. I explain the greenhouse effect and why gases like CO₂ and methane trap heat, before turning to the deeper issue of naive intervention—our tendency to assume linear, one-to-one outcomes in inherently complex systems. I discuss the concept of causal opacity, where true causes in interconnected systems are inaccessible, and emphasize nonlinear dynamics as the universal mechanism driving unpredictable side effects and potential collapse. The larger point is that policy and science must respect complexity rather than oversimplify it.
