Oct 19, 2021
Heat waves are often overlooked, yet they pose a significant threat, claiming more lives than any other natural disaster in the U.S. With climate change, these extreme temperatures are projected to become even longer and hotter. The hosts discuss the mechanics behind heat waves, including the impact of humidity on our bodies. They also explore the heat index and its health implications, particularly for vulnerable populations. Personal anecdotes and humor weave through a serious exploration of climate change and its mounting challenges.

Episode notes
High-Pressure Systems
- High-pressure systems force hot air downwards, preventing rising air and breezes.
- The trapped surface air continually warms, becoming dangerous to breathe.
Humidity's Role
- Humidity worsens heat waves by hindering sweat evaporation, the body's cooling mechanism.
- High humidity combined with high temperatures makes it feel even hotter.
Heat Index
- The heat index, or 'feels-like' temperature, considers humidity's effect on perceived heat.
- It provides a more accurate measure of how hot your body feels, not just air temperature.
