How We Survive

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.

Talk to enough experts about geoengineering and the conversation eventually turns to termination shock. That’s the idea that if we were to start cooling the planet and then suddenly stop, the resulting “shock” of heat could be catastrophic. It’s also the title of a novel by bestselling sci-fi writer Neal Stephenson, who explores the science, politics, and unintended consequences of trying to engineer the earth’s climate.

In this episode, we sit down with Stephenson to talk about what sci-fi can teach us about real-world climate solutions. But first: a climate idea so ambitious it sounds like it came straight from the pages of science fiction.

Could dimming the sun be the key to cooling things down before the climate crisis worsens? Some scientists say yes, that we can cool the earth by launching tons of sulfur dioxide into the stratosphere. It’s a type of solar geoengineering that was once seen as preposterous, meant to exist only in the pages of a sci-fi novel. But now, it’s a reality.

To find out for ourselves, we travel to Northern California where two entrepreneurs are launching sulfur-filled balloons from the top of stacked shipping containers. Later, we talk with scientists on both sides of this issue to find out if solar geoengineering could help prevent catastrophic tipping points or introduce a whole new slew of cascading consequences.

The climate crisis is escalating. We have to decarbonize our economy, but we’re moving too slowly. So, what’s the backup plan?

This season of “How We Survive” is about engineering nature: large-scale interventions that could be our last hope. We’ll explore technology being developed that could alter our weather patterns, transform our planet, and possibly save us all from the worst outcomes of the climate crisis. Or lead to catastrophic, unintended consequences.

On our hunt for solutions, we tag along with entrepreneurs trying to launch sulfur into the stratosphere, venture to the Utah mountains where there’s a serious endeavor to create more rain and snow, find out how (and why) scientists are trying to resurrect extinct animals.

Join us for the new season of “How We Survive,” starting May 27.

This week, we’re sharing an episode of another podcast we like — from another journalist named Amy.

Award-winning climate journalist Amy Westervelt returns with a new season of Drilled, a true-crime podcast about the deception, disinformation, and power structures standing between us and real climate solutions.

This season is called “Carbon Cowboys,” and exposes how Republican corn ethanol mogul Bruce Rastetter sold his “sustainable aviation fuel” to world leaders, from North Dakota to Brazil.

The problem? His “clean energy” project does nothing to help climate change.

“Drilled: Carbon Cowboys” follows the land grabs, pipelines, and political power stopping real progress from being made.

Here’s episode one.
