David Spratt joins hosts Arjana and Kathy to talk climate risk, tipping points, and the case for surface-based, reversible cooling alongside deep decarbonization. Practical, people-first strategies to cut heat stress now—no silver bullets, just grounded engineering.

Synopsis

Why mainstream assessments underplay systemic risk; how optimism bias shapes policy; and a practical framework for surface reflectors & passive cooling as an urgent complement to decarbonization.

Key points:

Risk realism and cascading tipping points

Overshoot: managing near-term heat

Surface-based cooling: scalable, reversible, community-level

Equity, governance, and measurement
