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

“Dehydrate the stratosphere to curb global warming? Scientists float new risky strategy.” by Paul Voosen. 2024.
“Contributions of Stratospheric Water Vapor to Decadal Changes in the Rate of Global Warming.” by Susan Solomon, et al. 2010.
“Considering intentional stratospheric dehydration for climate benefits.” by Joshua P. Schwarz. 2024.

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.
“Atrial Fibrillation.” CDC. 2022.

Butterfly Mimicry

“Butterflies mimic each other’s flight behaviour to avoid predators.” University of York. 2024.
“Butterfly Mimicry.” by Karin Kjernsmo. 2021.
“Mimicry in viceroy butterflies is dependent on abundance of the model queen butterfly.” by Kathleen L. Prudic, et al. 2019.

0:07.0	I'm Nate.
0:11.0	And I'm Callie. We're so excited to have you here with us at Curiosity.
0:14.0	If you're loyal listener, welcome back.
0:17.0	Today you'll learn about a potentially risky new idea to geoengineer our way out of extreme heat.
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.
