This is the science podcast for April 4th, 2025.

I'm Sarah Crespi.

First on the show, climate engineers face tough conversations with the public when it comes to testing things like changing the atmosphere to reflect more sunlight.

We're altering the ocean to suck up more carbon dioxide.

Breelian science writer Rebecca White joins me to discuss the questions people have about these

experiments and how to get collaboration and buy-in for their testing.

Next on the show, hyper-emesis gravidarmum, severe nausea, and vomiting during pregnancy,

is common in so many pregnant people and can have lasting maternal and infant health effects. This week, Marlena Faso wrote about

her path from suffering HG to finding linked genes and treatments for this debilitating complication.

I'm going to be honest that I actually am skeptical about climate engineering, changing, like,

the whole Earth system in order to reverse something that we've done accidentally.

And this is something that we've published in the new section on.

We've published in our policy section in science. I've read about it. I've

talked to people. Actually, asked our policy editor, Brad Weibel, why are we trying to test these things

when sci-fi movies tell us that it is a bad idea to try to intervene at this scale? And the

public does seem pretty averse. And to the best of my memory, what he said was someday,

some country or some international organization is going to have to possibly decide to do one of

these things. There is no better choice but to add this to the arsenal of our climate change

weapons. So we should probably know which one is the most likely to work and have the least side effects in

case that time comes to pass. But even getting basic data on geoengineering, testing out

deployments, the basic processes you would need to do, has been very controversial. This week in

science, freelance science writer Rebecca White wrote about where the rubber meets the road, where the science meets the people, and how bumpy it has been.
