Last year, we reported how extreme weather events may be dwindling the future of chocolate. Just last week, we saw an inkling of that: The Hershey Company announced it would significantly raise the cost of its candy in the face of historically high cocoa prices. So, we're revisiting host Emily Kwong's conversation with Yasmin Tayag, a food, health and science writer at The Atlantic. They get into the cocoa shortage: What's causing it, how it's linked to weather and poor farming conditions and what potential solutions exist. Plus, they enjoy a chocolate alternative taste test.

Much of the country is deep in the middle of a heat wave right now. And every summer, Duane Stilwell's town in Arizona seems to get hotter. It has him worried — and he's not the only one. Since 1980, the average number of heat waves in the U.S has doubled and the average length of a heat wave season has increased from 40 days to 70. Future summers, experts say, will be even hotter. But why exactly is that happening, and what can people do to protect themselves from the heat? This episode is part of Nature Quest, a monthly segment that answers listeners' questions about their local environment.

The twilight zone of the ocean is a mysterious place. At 200-1000 meters below the surface, it's a tough place to study. That's why, during World War II, people reading sonograms from this zone were perplexed when it looked as if the ocean floor was moving up. Every day. And then back down again before dawn. In this latest installment of Sea Camp, we explore what this historical mystery has to do with the Earth's ability to cycle and store carbon in the ocean's watery depths.

China has nearly cornered the market in rare earth minerals, which are a necessary component to much of our technology today. But China sources some of those rare earths and other heavy metals from neighboring Myanmar. And the ramped up in production there is causing downstream environmental concerns in Thailand. We go to Thailand to understand the issue. Learn more about sponsor message choices: podcastchoices.com/adchoices NPR Privacy Policy

For this second installment of the Sea Camp series, we explore the Great Pacific Garbage Patch. It's the largest of five gigantic garbage patches in the sea. These patches hang out at the nexus of the world's ocean currents, changing shape with the waves. These areas were long thought to have been uninhabited, the plastics and fishing gear too harmful to marine life. But researchers have uncovered a whole ecosystem of life in this largest collection of trash. Today, with the help of marine biologist Fiona Chong, we meet the tiny marine life that calls this place home. Also, exciting news!! WE HAVE A NEWSLETTER!

All across the U.S., there are aging oil and natural gas wells no longer in use. A lot of them don't have anyone on the hook to seal them up. Some estimate over a million such "orphan wells" still exist. Because they haven't been plugged, they're still leaking greenhouse gases and other chemicals into the atmosphere and into the land around them. What would it take to plug them — or even just one of them? For sponsor-free episodes of Consider This, sign up for Consider This+ via Apple Podcasts or at plus.npr.org.

Short Wave producer Hannah Chinn has adult-onset eczema. They're not the only one. Up to ten percent of people in the United States have it, according to the National Eczema Association — and its prevalence is increasing. Despite its ubiquity, a lot about this skin condition remains a mystery. So today, Hannah's getting answers. In this encore episode, they sat down with Raj Fadadu, a dermatologist at the University of California, San Diego, to ask: What is eczema? What triggers it in the first place? And might climate change make it worse sometimes? If you liked this episode, check out our episode on the science of itchiness. Also, follow us! That way you never miss another episode.

A warming climate doesn't just affect dry land — it affects the ocean, too. For years, Earth's ocean has acted as a heat sink for climate change: A large part of the heat generated by human use of fossil fuels is being absorbed by the ocean. And while the deep sea is largely unaffected by this heat absorption, oceanographers have discovered that the upper ocean currents are accelerating. That acceleration has the potential for huge knock-on effects, including sea level rise, changing fish migration cycles, shifting storm patterns, and more. This is the first episode of Sea Camp, Short Wave's summer series exploring the intriguing and otherworldly depths of the ocean. Follow us every Monday through August as we travel from the sunlit zone to the sea floor. Interested in more stories about the ocean? Email us your question at shortwave@npr.org.

Mosquitoes are the deadliest animal on the planet, and some of them may be on the rise. At least in listener Abigail Krich-Starr's area, that's due to warmer, wetter weather — which, yes, is linked to climate change. But it doesn't stop there: Ecologists and entomologists say increased heat could also alter mosquito behavior, shift their natural habitat, and even change how pathogens incubate and spread inside their bodies. So how do you protect yourself against the (mosquito) masses? Our experts suggested several things: - Assess your risk by checking local mosquito surveillance efforts, like this one for the state of Massachusetts - Consider rescheduling outdoor events happening between dusk and dawn, which is peak biting time for multiple mosquito species - Wear long-sleeved shirts and pants, weather-permitting, to limit exposed skin - Use an EPA-approved DEET repellent, and/or a permethrin spray for clothing and outdoor gear This episode is part of Nature Quest, a monthly Short Wave segment that answers listener questions about the local environment.

Homeowners' insurance isn't just getting more expensive ... it's also getting harder to secure in the first place. Across the country, an increase in climate-related disasters like heat waves, wildfires and hurricanes is creating challenges for both insurers and their customers. One successful strategy taking hold in Alabama and other states: Climate-proofing houses — and incentivizing it with insurance discounts. Still, not all states or homeowners face similar risks. And insurers aren't legally required to take climate-proofing into account when assessing the insurability of a home. That's why states are experimenting with different programs — and insurance legislation — to find a solution. This episode is part of NPR's Climate Solutions Week: a series of stories covering real world solutions for building, and living, on a hotter planet.

Whether it was her history making win in 2017. Or the history she made as only the second woman elected to lead a country to give birth while IN office. Or her decision to step away from power after leading New Zealand through crisis after crisis. Jacinda Ardern could never be described as a TYPICAL politician. But perhaps the most norm-busting feature of her time as Prime Minister was her rejection of the old ways of leadership. Now as she reflects on her time as Prime Minister of New Zealand Ardern is emphasizing the need to lead with kindness and empathy.

By 2028, Lawrence Berkeley National Laboratory forecasts that U.S. data centers could use as much as 12% of the nation's electricity. The reason: generative AI. Since 2022, AI innovation by four leading tech companies — Google, Microsoft, Meta and Amazon — has led to annual increases in both energy and water consumption. So, in this episode, Short Wave co-host Emily Kwong probes huge water footprint of AI. We begin with the rise of data centers, then look at how computers came to need so much water and, finally, what tech companies are doing to try to turn the ship around. P.S. Part 2 talks about the leading solutions in the green AI movement. So don't miss our Friday episode! Curious about tech and the environment?

A fish walks into a pharmacy ... well, not exactly. Fish aren't being prescribed anti-anxiety drugs. But they are experiencing the effects. Researchers have found more than 900 different pharmaceutical ingredients in rivers and streams around the world, though they're not yet sure how this could change the behavior of fish and other aquatic animals in the wild. "We can't, you know, dump a bunch of pharmaceuticals into the river," says Jack Brand, biologist at the Swedish University of Agricultural Sciences. Instead, Jack's team did the next best thing – with some surprising results. This episode was reported by NPR science correspondent Jon Lambert. Check out more of his reporting.
