Scott Detrow, an NPR host and expert in space and science reporting, joins to discuss the environmental impacts of AI as revealed by Cornell University's study. The alarming projections indicate AI could contribute millions of metric tons of CO2 and significant water usage by 2030. Scott also explores the intriguing possibility of life on Enceladus, one of Saturn's moons, thanks to its stable subsurface ocean. Additionally, learn about the unique anatomy of chameleons, including their fascinating coiled optic nerves that enhance their eye mobility.

Episode notes
AI Could Break Climate Targets
- Cornell researchers project AI could add 24–44 million metric tons of CO2 by 2030 if current growth continues.
- They also estimate AI could demand as much water as 6–10 million Americans annually, threatening climate goals.
Place Data Centers Where Impact Is Lower
- Build data centers in places with cleaner grids and low water stress to reduce environmental harm.
- The study recommends locations like Midwest and wind-belt states already moving to clean energy.
Enceladus Has A Stable Ocean Heat Flow
- Enceladus likely maintains a stable heat flow, making its subsurface ocean thermally steady.
- Stable heating increases the chance that life could have emerged and persisted there.
