Your geoengineering questions, answered!
01/07/2026 | 17 min
This season, we explored large-scale climate interventions that could be our last hope. One intervention in particular, solar geoengineering, made a lot of listeners’ heads spin. (We’re right there with you.)

This episode, we answer some of your most pressing questions about solar geoengineering. We get into whether solar sunshades could harm crops, what international efforts around solar geoengineering look like, and what would happen if a powerful country went rogue and put sulfur dioxide into the stratosphere. Plus, we look at a solution to some of these more extreme solutions: decarbonizing.
Should we mess with nature?
24/06/2026 | 22 min
All season, we’ve been unpacking the controversial ways we’re messing with nature to save the planet. In this episode, we explore the wildest intervention to date: de-extinction. We take a tour of Colossal Labs, the $10 billion Dallas startup betting it can reverse-engineer extinction itself, to see how they plan to turn pigeons into dodos and Asian elephants into woolly mammoths.

But whether it’s bringing back the woolly mammoth from extinction or shooting sulfur dioxide into the stratosphere, just because we can mess with nature, does that mean we should? After the tour, host Amy Scott chats with Pulitzer Prize-winning environmental journalist Elizabeth Kolbert to find out.
A Carbon Burial at Sea
17/06/2026 | 28 min
We can't avoid catastrophic warming without also capturing and storing carbon dioxide — both the carbon we've already emitted and the carbon we continue to emit through industries that are tough to decarbonize, like steel, petrochemicals, and cement.

Europe is a leader in Carbon Capture and Storage (CCS), with a goal of storing at least 50 million tons of captured CO2 a year by the end of this decade.

So this episode, we team up with Germany-based reporter Sam Baker from the DW podcast “Living Planet.” We follow carbon dioxide from its source at a cement plant, all the way to its final resting place under the North Sea. And we look beyond the hype to see if Carbon Capture and Storage could be a real climate solution. Or just another way for the fossil fuel industry to keep on drilling.
How conspiracy theories impact geoengineering efforts
15/06/2026 | 24 min
Across the country, anti-geoengineering bills are being proposed in state legislatures. These bills would ban the intentional release of chemicals into the atmosphere for the purpose of affecting sunlight or weather, and could impact future research into stratospheric aerosol injection — or even cloud seeding.

But, unlike environmentalists that are advocating against the potential use of geoengineering as a climate solution, the bills’ proponents think that it’s already happening. Their proof? You can see it in the sky, they say: just look up.

In this episode of “How We Survive,” Amy Scott talks with producer Rachel Kahn about how a once-fringe conspiracy theory could impact the future of geoengineering.
Make It Rain
10/06/2026 | 32 min
Can a technology used for war help prevent an environmental catastrophe in the making?

Cloud seeding is a technique where particles, usually silver iodide, gets dispersed into clouds to help generate more rain or snow and it’s been around for 80 years. During the Vietnam War, the U.S. used cloud seeding in a top secret mission called Operation Popeye, to prolong the monsoon season in Vietnam. It’s since been deployed by state governments and private companies to bring more water to arid places. The only problem? It was hard to verify just how well it worked, which meant it was hard to make any money doing it. Until now.

We tag along with a team of cloud seeders in Utah as they race to try to save the Great Salt Lake, and build a rainmaking empire.

Acerca de How We Survive

“How We Survive” is an award-winning podcast from Marketplace about the messy business of climate solutions. From the glitz and glam of Miami to the punishing Arizona desert, to a sinking island that our national security depends on, every season, we take listeners on an adventure. We explore the innovative, surprising, and occasionally disturbing ways that people are navigating solutions to a changing climate. Previous seasons explored the underbelly of the lithium extraction economy with Tech expert Molly Wood; investigated the red-hot Miami real estate market that’s increasingly vulnerable to storms and sea level rise with journalist Amy Scott; and examined the world’s biggest emitter of greenhouse gases — the U..S military — with Marketplace host and former Navy pilot Kai Ryssdal. In addition to long-form deep dive seasons, “How We Survive” has a spin-off series called “Burning Questions” that empowers listeners with information they can implement in their lives. We answer questions about climate-safe places to live, the best and worst foods to eat for the environment, maintaining hope when all you want to do is doom-scroll, and tips to climate-proof your house.
