Coral reefs are among the planet’s most beautiful treasures, hosting creatures strange and colorful. They’re more than just pretty, though. Coral reefs provide vital habitats for a vast array of marine organisms, they are an essential piece of ocean ecosystems, and they actually protect coastlines from erosion. This week on Sea Change Radio we speak to Curt Storlazzi from the US geological survey who outlines a recent study promoting the bolstering of coral reefs off of Puerto Rico and Florida. Storlazzi compares coral reefs to seawalls in terms of protecting us from rising sea levels, gives a snapshot of the study’s cost benefit analysis, and explains how the proposed reef bolstering program could help protect vulnerable coastal populations.Read the show transcript

California kicked off 2025 with some of the most devastating wildfires in the state’s history. Thousands have already lost their homes, dozens have been killed, and as of today the largest of the Los Angeles area fires is only 14% contained. This week on Sea Change Radio we speak with meteorologist Anthony Edwards of the San Francisco Chronicle to learn more about what caused the fires, how climate change is making events like these more commonplace and inevitable than ever, and what we can all do to better prepare for them. Then, we take a few minutes to look at the burgeoning industry of amateur meteorology in the ski industry and the impact that the growth in untrained meteorological professionals is having on Edwards’s job, and on the field in general.Read the show transcript

When you visit the World Wildlife Fund’s list of critically endangered species, the first animals named are large, beloved mammals like the African Forest Elephant and the Eastern Lowland Gorilla. While these majestic creatures tug at our heartstrings, there are also a lot of smaller, more unsung organisms that are in grave risk of extinction, like the lowly freshwater mussel. This week on Sea Change Radio, we speak to environmental writer, John Platt, the editor of The Revelator to talk about some of the less glamorous animals that have recently been declared extinct or are on the brink of extinction. First, we take a deep dive into the plight of the ivory-billed woodpecker, a regal swamp-dwelling bird whose demise may or may not have been premature. Then we discuss why Hawaii is referred to by some naturalists as the extinction capital of the world, and look at the ethical quandaries presented by the emerging field of resurrection biology, also known as de-extinction.

This week on Sea Change Radio we speak to Lisa Song of ProPublica about her recent work spotlighting efforts by the plastics industry to make its fossil fuel-based products seem benign. We examine how plastic recycling falls short in many areas, look at the problems surrounding a relatively new plastic recycling process called pyrolysis, and then discuss her trip to Ottawa, Canada where she attended a UN conference which purported to be plastic-free.

This week on Sea Change Radio, a conversation about the vast and varied coastline of the great state of Maine with Peter Slovinsky, a marine geologist with the Maine Geological Survey. We learn about living coastlines, efforts to protect Maine’s coast from rising seas and more frequent storms – and get a bit of a geography lesson at the same time.

When we think about the transition to renewable energy sources, many of us imagine rooftop solar panels and wind turbine-dotted hills. But it’s not just about capturing energy, it’s also about keeping it. This week on Sea Change Radio we speak with Matt Simon, a Grist senior staff writer, to discuss long-duration energy storage. The transition to renewables for utilities is still very much evolving — efficiency, intermittency, and storage are among the issues scientists have yet to perfect. Simon shares some ideas for how we can build upon existing technologies to store solar and wind power, with longer capacity than lithium-ion batteries, ranging from reservoirs and caverns to our existing fleet of electric vehicles.Read the show transcript

Since 1973, the Tyler Prize for Environmental Achievement has been bestowed upon people who have made a significant impact in the fight for a sustainable planet. In 2019, we spoke with that year’s Tyler Prize Laureate, Warren Washington, to learn about the beginnings of his groundbreaking career as an atmospheric scientist. This week on Sea Change Radio, we pay tribute to Dr. Washington, who recently passed away at the age of 88. He was the second African American to receive a PhD in meteorology, a former chair of the National Science Board, and a senior scientist at the National Center for Atmospheric Research in Boulder, Colorado. Then, we revisit part of our conversation with physicist Hattie Carwell to learn about her long, illustrious career in the atomic energy space as well as her work at the Museum of African American Technology.

In the wake of the recent U.S. election which was beyond disappointing to those of us who care about the planet, Sea Change Radio will not be closely covering political issues and the machinations of the incoming administration simply because it will be too depressing. Instead, we will continue to cover the shift to sustainability. Rather than focusing on humans this week on Sea Change Radio, we dig into the archives and turn our gaze to the insect world. First, we speak to two scientists, Dylan Gaeta and Scot Miller, from Johns Hopkins University, who share their research on the effects that termite pesticides are having on the climate. Then, we hear from Anne Carlson, the CEO of Jiminy’s, who talks about the benefits of her company’s insect-based dog food.

It seems fitting this week, as millions of Americans sit down to an enormous feast, that we discuss the topic of over-indulgence — and we are not just talking about turkey and pie. This week on Sea Change Radio, we speak with Canadian environmental journalist Lloyd Alter about sufficiency. We discuss the need to develop sufficiency measures in the sustainability space, talk about examples of sufficiency from the corporate world, and look at Paul Brannen’s recent book “Timber!” which makes the case that wood is a more sustainable building material as compared to mined or manufactured compounds.

Egypt, the United Arab Emirates and Azerbaijan. For three years in a row now, the United Nations has chosen to hold its flagship environmental meeting – the UN Conference of the Parties, or COP – in a country largely dependent on oil revenues for its economic well-being. This week on Sea Change Radio, we speak with Bob Berwyn of Inside Climate News, currently in Baku, Azerbaijan covering COP29. We examine the problems associated with holding this ever-expanding event in a petro-state, discuss the logistics behind the selection, and consider the key takeaway policies from the conference.Read the show transcript
