Summary
Today, you’ll learn about a potentially risky new idea to geoengineer our way out of extreme heat, bad news for fans of artificially sweetened drinks, and an incredible new discovery about butterflies.
Geoengineering

Artificial Sweeteners
- “Artificially sweetened drinks linked to risk of irregular heartbeat, study finds.” by Erum Salam. 2024.
- “Sweetened Beverages, GEnetic Susceptibility, and Incident Atrial Fibrillation: A Prospective Cohort Study.” by Ying Sun, et al. 2024.

| 0:22.0 | Some bad news for fans of artificially |
| 0:25.2 | sweetened drinks, and an incredible new discovery about butterflies. |
| 0:30.3 | Ooh butterflies! Let's jump in. |
| 0:33.0 | In the race to solve climate change, we talk a lot about carbon dioxide and methane. |
| 0:39.0 | You know, as anyone who listens to the show already knows, these are greenhouse gases. |
| 0:42.0 | When they are released into |
| 0:43.7 | the atmosphere they act like the glass covering a greenhouse. Right they trap heat |
| 0:48.7 | within our little earthly air bubble and cause the temperatures to slowly slowly, |
| 0:52.8 | and in some cases not so slowly, especially considering geologic time. |
| 0:57.2 | So we all know these gases are important drivers of climate change, |
| 1:00.8 | but did you know there's another significant greenhouse gas that often |
| 1:04.6 | gets overlooked? That's right, it's called water. |
| 1:07.8 | Okay, no, water's not a gas. Okay, yeah, not all. We're talking water vapor here. |
| 1:17.0 | Sure. |
| 1:18.0 | Chemically water. |
| 1:19.0 | The water moisture that reaches the high atmosphere |
| 1:22.0 | has a very similar heat trapping quality. |
