Hey smarties! We’re on a break for the holidays and revisiting some favorite episodes from 2022. We want to say a big thank-you for being part of the “Make Me Smart” family this year — every voicemail, question and donation made a huge difference. None of us is as smart as all of us, and we couldn’t do this show without you. There’s still time to help Marketplace reach its end-of-year fundraising goal. If you can, please donate here. Thanks, happy holidays and we’ll see you in the new year.

As the threat of climate change grows, expect to hear more about solar geoengineering.

It came up during our recent episode with sci-fi author Neal Stephenson, and it involves spraying tiny particles into the stratosphere to deflect the sun’s rays away from the Earth and cool the planet.

“It’s a pretty old idea and it has run into such opposition, in terms of research, that we have yet to have any rigorous tests of whether it is even, you know, remotely possible,” said Elizabeth Kolbert, a climate journalist and author of “Under a White Sky: The Nature of the Future.”

Critics still believe the risks outweigh potential benefits, but that hasn’t stopped others from supporting the idea as a potential solution to our climate woes.

On the show today, the promise and peril of solar geoengineering.

In the News Fix, we’ll discuss a historic settlement between Sandy Hook families and gun manufacturer Remington Arms. Also, we’ll explain why billionaire philanthropists are a social policy issue.

Then we’ll hear from listeners about last week’s episode on the NFL racial discrimination lawsuit, and we’ll have an answer to the Make Me Smart question that will teach you something about weather forecasting!

Here’s everything we talked about today:
