In the humid rainforests of northern and eastern Madagascar reside seven newly described frog species. They often hang out near fast, flowing rivers. These treefrogs' high-pitched, "futuristic" sounds may help male frogs attract females over the sound of nearby rushing water. They also are what inspired their Star Trek-themed names.

Norway is the largest exporter of salmon in the world. And while some of those fish are wild-caught, many are raised in "fish farms"- large cylindrical pens made of nylon in the open water. Sometimes these farmed fish escape, mixing with the local population and causing ecological issues. We see farmed fish in a Norwegian fjord and hear about potential solutions to the problem.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Even though there are more than 10,000 rock glaciers in the western United States, most people would look at one without knowing it. Unlike the snowy glaciers we're more familiar with, rock glaciers are under-researched and hiding in plain sight. But inside these glaciers covered with rocks is a little bit of climate hope.Read more of science correspondent Nell Greenfieldboyce's reporting here.

Recently, the state of Washington embarked on an ambitious new plan to combat climate change. Taking a page from economics textbooks, the state instituted a statewide "cap and trade" system for carbon emissions. The state establishes a cap on the total amount of carbon pollution it is willing to allow each year, and then gives away or auctions off carbon emission permits that add up to that total. Companies can then trade those permits on the open market.Economists love cap and trade plans because they establish a limit on carbon emissions while letting the market find the most efficient way for decarbonization to occur. But cap and trade has had a hard time catching on, especially in the U.S.The stakes are high for Washington's new plan. If it succeeds, it could convince other states to implement their own versions, but if it fails, it might serve as a cautionary tale. On today's show, we take a look at how Washington's grand experiment with cap and trade is faring.This episode was hosted by Keith Romer and Kenny Malone.

Lightning: It happens all the time, and yet the exact details of how it's made has long eluded scientists. That is, until now. New research out this week in the journal Nature holds new insights into the precursor to lightning. To figure it out, researchers flew a NASA ER-2 – essentially the research version of a spy plane – over several tropical thunderstorms. What they found: The same high energy radiation is found in places like neutron stars and around black holes. Want to hear more stories about the science behind natural phenomena?

Governors across the southeastern United States have declared statewide states of emergency as Hurricane Helene continues its ascent. After forming in the northwestern Caribbean Sea Tuesday, Helene escalated from a tropical storm, then to a cyclone, and finally to a Category 4 hurricane by the time it made landfall late Thursday night. We talk to hurricane climatologist Jill Trepanier about how a storm tropical storm system rapidly intensifies into a major hurricane, the impact of a changing climate on future storms — and why the devastation doesn't stop at the shore.Follow local updates on Hurricane Helene.Want to know more about the scientific underpinning of serious weather events?

In California's Napa Valley, the nation's unofficial wine capital, one varietal reigns supreme: cabernet sauvignon. But climate change is threatening the small blue-black grapes for which cabernet sauvignon is named. Increasingly severe heat waves are taking a toll on the grape variety, especially in late summer during ripening.To kick off NPR's Climate Solutions Week, climate correspondent Lauren Sommer joins host Regina G. Barber for a deep dive into the innovations wineries are actualizing — and the ways that cabernet farmers and fans alike could learn to adapt.Climate change is affecting our food, and our food is affecting the climate. NPR is dedicating a week to stories and conversations about the search for solutions.Read more of Lauren's reporting on how climate change is affecting wine.

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. They sat down with Raj Fadadu, a dermatologist at UC 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!

What does it mean to do the greatest good for the greatest number? When the Los Angeles Aqueduct opened in 1913, it rerouted the Owens River from its natural path through an Eastern California valley hundreds of miles south to LA, enabling a dusty town to grow into a global city. But of course, there was a price.Today on the show: Greed, glory, and obsession; what the water made possible, and at what cost.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

The U.S. is the largest exporter of natural gas in the world. And Louisiana's Gulf Coast is where much of America's natural gas is piped in to be liquified for export.Over the last twenty years, liquified natural gas (LNG) has been heralded as a clean and efficient "bridge fuel" for nations transitioning away from coal and oil, towards a future of renewable energy. But the promise of LNG has not reflected reality. In today's episode of The Sunday Story, WWNO reporters Halle Parker and Carlyle Calhoun talk about the impact of the LNG export industry on Louisiana's Gulf Coast. And they follow the supply chain of LNG all the way to Germany and Japan.To hear more of Halle and Carlyle's reporting on LNG, listen to their three-part series, "All Gassed Up," on the podcast Sea Change from member stations WWNO and WRKF.Part One: The Carbon CoastPart Two: The German ConnectionPart Three: The Sugar Daddy of LNGLearn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

More than a hundred years ago, a British engineer proposed linking two rivers in India to better irrigate the area and cheaply move goods. The link never happened, but the idea survived. Today, due to extreme flooding in some parts of the country mirrored by debilitating drought in others, India's National Water Development Agency plans to dig thirty links between rivers across the country. It's the largest project of its kind and will take decades to complete. But scientists are worried what moving that much water could do to the land, the people — and even the weather. Host Emily Kwong talks to journalist Sushmita Pathak about her recent story on the project. Read Sushmita's full story here.Interested in more science stories like this?

Every year for two weeks between mid-May and mid-June, Congaree National Park in South Carolina is home to a fairy-tale-like display of flashing lights. These rhythmic performances happen all because of thousands of fireflies, flashing their belly lanterns at exactly the same time. According to the National Park Service, there are just three types of these synchronous fireflies in North America, making the experience all the more magical for the lucky visitors who get the chance to see them. Firefly scientists and enthusiasts hope these displays in places like Congaree will inspire people to care about other kinds of fireflies, also known as lightning bugs, in the U.S., which are not as well-studied – or well-protected – as synchronous ones. Some community scientists are already taking on this mission with projects like the Firefly Atlas, where volunteers can help survey for fireflies and report sightings.This story was originally reported for NPR by science correspondent Pien Huang.

About ten years ago, science writer Ferris Jabr started contemplating Earth as a living planet rather than a planet with life on it. It began when he learned that the Amazon rainforest doesn't simply receive the rain that defines it; rather, it helps generate that rain. The Amazon does that by launching bits of biological confetti into the atmosphere that, in turn, seed clouds. After learning this, he began looking for other ways life changes its environment. That led to his new book Becoming Earth: How Our Planet Came to Life. He talks to host Regina G. Barber about examples of life transforming the planet — from changing the color of the sky to altering the weather. Have a story about the environment you'd like us to cover?

The National Oceanic and Atmospheric Administration is predicting a record number of hurricanes this season, which began on June 1 and runs through Nov. They're forecasting anywhere from 17 to 25 storms in the Atlantic basin, including at least four major hurricanes. Scientists think this storm activity could be due to strong winds, warmer ocean temperatures and a scientific mystery unfolding in the Atlantic. Questions about hurricanes or other weather disasters?
