The Panama Canal has been dubbed the greatest engineering feat in human history. It's also (perhaps less favorably) been called the greatest liberty mankind has ever taken with Mother Nature. But due to climate change, the Canal is drying up and fewer than half of the ships that used to pass through are now able to do so. So how did we get here? Today on the show, we're talking to Cristina Henriquez, the author of a new novel that explores the making of the Canal. It took 50,000 people from 90 different countries to carve the land in two — and the consequences of that extraordinary, nature-defying act are still echoing through our present.

President Biden has been pushing new regulations to promote electric vehicle production to combat the climate crisis — and former president Trump is using those regulations as a talking point against Biden. To break down how cars became the latest weapons in the culture wars, host Brittany Luse is joined by NPR's transportation correspondent Camila Domonoske and Dan Brekke, a reporter and editor at KQED in San Francisco who covers transit. Together, they talk about why Americans are so invested in their cars — and how cars became more than just a policy battle. Then Brittany discusses a new HBO documentary series that is making waves right now: Quiet On Set. The show alleges a pattern of sexual harassment behind the scenes at Nickelodeon, and includes interviews with several former child stars describing experiences that range from taking part in sexualized gags to facing downright sexual abuse while working for the network. Brittany looks closer at the trouble with child performers with Joan Summers and Matthew Lawson, co-hosts of the Eating for Free podcast. They discuss what makes child performers especially vulnerable to abuse — and they ask why society demands performances from children.

"A total solar eclipse is so much more than something you just see with your eyes. It's something you experience with your whole body," says science writer David Baron. Learn more about sponsor message choices: podcastchoices.com/adchoices NPR Privacy Policy

Historic numbers of animals across the globe have become endangered or pushed to extinction. But some of these species sit in limbo — not definitively extinct yet missing from the scientific record. Rediscovering a "lost" species is not easy. It can require trips to remote areas and canvassing a large area in search of only a handful of animals. But new technology and stronger partnerships with local communities have helped these hidden, "uncharismatic" creatures come to light.

Across the animal kingdom, menopause is something of an evolutionary blip. We humans are one of the few animals to experience it. But Sam Ellis, a researcher in animal behavior, argues that this isn't so surprising. "The best way to propagate your genes is to get as many offspring as possible into the next generation," says Ellis. "The best way to do that is almost always to reproduce your whole life." So how did menopause evolve? The answer may lie in whales. Ellis and his team at the University of Exeter recently published a study in the journal Nature that studies the evolution of menopause in the undersea animals most known for it. What they uncovered may even help explain menopause in humans. Curious about other animal behavior mysteries? Email us at shortwave@npr.org.

On August 6, 1945, a stone-faced President Harry Truman appeared on television and told Americans about the atomic bomb being dropped on Hiroshima. The attack on Hiroshima marked the first time nuclear power was used in war, but the atomic bomb was actually tested a month earlier in the Jornada del Muerto desert of New Mexico. At least hundreds of New Mexicans were harmed by the test's fallout. Radiation creeped into the grass their cows grazed, on the food they ate, and the water they drank. A program compensating victims of government-caused nuclear contamination has been in place since 1990, but it never included downwinders in New Mexico, the site of the very first nuclear test. This week, the Senate voted to broaden the bi-partisan legislation that could compensate people who have suffered health consequences of radiation testing. Now, the bill will go to a House vote. Generations after the Trinity Nuclear Test, will downwinders in New Mexico finally get compensation?

Why is it so complicated to save the Everglades? The Everglades is home to the largest mangrove ecosystem in the western hemisphere and a sanctuary for over three dozen endangered and threatened species. It also provides fresh water, flood control, and a buffer against hurricanes and rising seas for about 9 million Floridians. But climate change, pollution, agriculture and rapid development are causing potentially irreversible damage. In 2000, the state of Florida and the federal government struck an extraordinary deal to save the Everglades. The Comprehensive Everglades Restoration Plan was the largest ecosystem restoration project in the world. But from the moment it was signed into law, things got complicated. Now almost 25 years later, the Everglades is as endangered as ever, and the problems have become even more difficult—and expensive—to solve. Today on The Sunday Story, Ayesha Rascoe talks with WLRN's Jenny Staletovich. Jenny has a new podcast series out called Bright Lit Place that tells the dramatic story of the Everglades, what's been done to the ecosystem, and what needs to happen to save it.

In the last few years, a new trend has emerged on social media: de-influencing. Instead of selling, de-influencers encourage their followers to stop buying things they don't need. De-influencers are also using this trend as an opportunity to raise awareness about the negative impact of overconsumption on the environment. From plastic packaging to useless gadgets that end up in landfills, overconsumption doesn't just have a negative effect on our wallets, but also on our planet and climate change. We look at what role de-influencers can play in helping to address climate change and spreading the message of sustainable living.

Lately, paleoecologist Audrey Rowe has been a bit preoccupied with a girl named Elma. That's because Elma is ... a woolly mammoth. And 14,000 years ago, when Elma was alive, her habitat in interior Alaska was rapidly changing. The Ice Age was coming to a close and human hunters were starting early settlements. Which leads to an intriguing question: Who, or what, killed her? In the search for answers, Audrey traces Elma's life and journey through — get this — a single tusk. Today, she shares her insights on what the mammoth extinction from thousands of years ago can teach us about megafauna extinctions today with guest host Nate Rott.

It was a year ago this month that a Norfolk Southern freight train with 38 cars derailed in East Palestine, Ohio. Twenty of those train cars carried hazardous materials. In the days after the crash officials, decided to burn off one of those hazardous materials, vinyl chloride. The burn and massive plume of smoke it created caused environmental problems and concerns about the health and safety of residents. A year after that devastating derailment and chemical burn the train company Norfolk Southern and the EPA say the air and water are safe. The people who have to go on living there aren't so sure.

In 1986 the Chernobyl nuclear power plant exploded, releasing radioactive material into northern Ukraine and Belarus. It was the most serious nuclear accident in history. Over one hundred thousand people were evacuated from the surrounding area. But local gray wolves never left — and their population has grown over the years. It's seven times denser than populations in protected lands elsewhere in Belarus. This fact has led scientists to wonder whether the wolves are genetically either resistant or resilient to cancer — or if the wolves are simply thriving because humans aren't interfering with them. This episode, researchers Shane Campbell-Staton and Cara Love talk through what might be causing this population boom. Plus, why researchers in the field of human cancer are eager to collaborate with them. Want to hear about other ways humans are impacting the planet? Email us at shortwave@npr.org.

Every year world leaders gather at the Conference of the Parties, or COP, to devise solutions to what amounts to a growing existential crisis for humankind: our rapidly heating planet. The United Arab Emirates is hosting COP28 this year. The goal of the conference is to decrease emissions and protect the planet. But leading the climate talks is the head of one of the biggest oil companies in the world, in a nation that derives much of its wealth from oil. Are the goals of this meeting truly in sync with the goals of the hosts? NPR's Miles Parks speaks with NPR international correspondent Aya Batrawy from COP28.

Pope Francis says he will attend the COP28 climate conference in Dubai next month, which would make him the first pontiff to attend the annual UN gathering. The pope has made addressing the climate crisis an important focus since 2015, when he published an encyclical on climate change and the environment. Last month, he doubled down on his stance with a new document – Laudate Deum. It's a scathing rebuke of the inaction by world leaders over the last eight years. As Francis takes on an even bigger role in climate activism. What does he hope to achieve? And how does this all fit into his broader legacy as leader of the world's 1.3 billion Roman Catholics. NPR's Scott Detrow spoke with Fordham professor Christiana Zenner, and Associated Press Vatican correspondent Nicole Winfield, about Pope Francis and his role in advocating for action on climate change.

Saturday, the entire coastal town of Grindavik, Iceland was evacuated. That's because over the weekend, the country experienced nearly 2,000 earthquakes within 48 hours. And they've kept coming since then – in swarms. Scientists think the quakes are indicative of magma moving closer to the surface in the country's southwestern peninsula and that a local volcano could erupt at any moment. Today on the show, host Regina G. Barber talks to volcanologist Diana Roman about the science behind these earthquakes. Got science to share? Email us at shortwave@npr.org.

Some people keep dogs in their backyards. In the Florida Keys, some residents have deer the size of a golden retriever in their yards. As sea levels rise and salt water climbs higher on the islands, it's shrinking habitat for this deer — which already has an estimated population of at most 1,000. Today, host Regina G. Barber hears from reporters Nate Rott and Ryan Kellman about the Key deer, and how rising sea levels are forcing wildlife managers to ask big questions about the future of the subspecies. In this episode, we incorrectly stated that Valerie Preziosi is the founder of Key Deer Alliance. In fact, she is the founder and director of the organization Save Our Key Deer.
