 Episode notes 
Wildfire Smoke Sparked The Book
- During the pandemic Park and his wife in Los Angeles experienced record wildfires and pervasive smoke while stuck in apartments.
- That personal helplessness partly motivated him to write Slow Burn and study practical, local climate impacts.
Small Climate Shifts Stack Into Big Harms
- Moderate increases in hot days (high 20s–low 30s °C) add up and reduce productivity, health, and learning.
- Wildfire smoke downwind can cause far more mortality cumulatively than flames themselves.
Add A 'Slow Burn' Mental Heuristic
- People use fast, emotional heuristics that favor dramatic climate narratives over statistical nuance.
- Park urges adding a 'slow burn' heuristic to judge incremental harms and policy trade-offs.
