Episode notes
Dwayne's Harrowing Arizona Heat
- Dwayne Stilwell experienced 113 days above 100°F consecutively in Arizona, killing his fig trees and neighbour from heat stroke.
- He feared staying due to the forbiddingly hot summers, signaling extreme heat's devastating local impact.
Physics Behind Earth's Warming
- Earth's warming stems from an imbalance in energy absorption and emission due to trapped greenhouse gases.
- The planet heats up to restore radiative balance, explaining rising global temperatures and longer heatwaves.
Humidity Amplifies Heat Risk
- Higher humidity worsens heat danger by reducing body sweat evaporation efficiency.
- When sweat can't evaporate, the body's cooling fails, raising risks of heat exhaustion and death.
