    Daniel Swain does more than Predict the Weather

    In the latest episode of Rising Tide the Ocean Podcast David and Vicki talk with Boulder- based weather and climate scientist Dr. Daniel Swain about the emerging El Nino that’s predicted to become a major, perhaps historic one this fall on top of a new marine heatwave already impacting the Pacific coast. Along with working with the University of California and National Science Foundation’s Center for Atmospheric Research, Daniel also shares his knowledge of weather and climate across our blue world through his popular Weather West blog and Weather West YouTube channel. So, he’s the right informed communicator in this summer of climate disasters to talk about what we can expect and why in the coming months. Let’s find out what might happen along our coasts and rolling onto our shores with the Rising Tide.

    Aaron Eger is yes, Eager to Help the Kelp

    In the latest episode of Rising Tide the Ocean Podcast Oceanographer and Blue Frontier board member Joy Leilei Shih and David Helvarg talk with Australian based scientist Dr. Aaron Eger, one of the world’s top kelp researchers. Based at the University of New South Wales in Sydney, he is the founder and program director of the global ‘Kelp Forest Alliance,’ also the lead author of 3 major scientific kelp reports that have come out over the last 4 years. These include one that identifies the value of kelp forests at roughly half a trillion dollars a year. Aaron discusses food and biodiversity, coastal protection, nutrient and carbon reduction and other values of kelp. He’ll also talk about growing up in coastal British Columbia and the fun of being in on and around macro-algae as the other great fast-growing world forest that is less known because it thrives underwater. Also, he’ll say what threatens it and what we can do about that. So, dive in with us.

    Youth Ambassadors Crash Washington

    An inside look at the determined youth ambassadors advocating for oceanic policy reform. In the latest episode of Rising Tide the Ocean Podcast David and oceanographer and Blue Frontier board member Joy LeiLei Shih talk about our Youth Ambassador program before interviewing our 2026 ambassadors – Avery, age 13, Jack, 13, Liam, 14 and Kianna 16 on their return from an Ocean Week trip to Washington DC. We discuss their impressions after having worked the halls of Congress taking a dozen meetings over 3 days to educate their elected officials and staff members on the issues they are involved in from plastic waste to sea turtle protection. We also discuss the direct meetings they held with Senators Padilla, Schiff and Schatz and Representatives Raskin, Huffman and Liccardo. It’s a great conversation and reminder that our ocean youth – even those in middle school - are not necessarily our leaders of the future - but can be leaders today if we work with and mentor them.

    Paul Greenberg on Fishing, Writing and Semiotics

    Louie Psihoyos on Dolphins, Plastics and More

    Unraveling the Threads of Change: From Photography to Global Environmental Advocacy Academy Award-winning director Louie Psihoyos returned to the Rising Tide Ocean Podcast for a conversation as wide-ranging and urgent as his films. Host David Helvarg sat down with Psihoyos before a live audience during SF Climate Week at the downtown San Francisco studios of KALW public radio — and the exchange didn't disappoint. Psihoyos traces his unlikely path to ocean advocacy: a kid from Iowa, drawn early to photography and the sea, who eventually landed at National Geographic — beginning, as origin stories often do, at the bottom, sifting through a garbage dig. From there he rose to become one of the most consequential documentary filmmakers working today, a man who doesn't just point a camera at environmental catastrophe but builds covert operations around it. He recounts the making of The Cove, his shattering exposé of the dolphin slaughter in Taiji, Japan — a film that required as much tradecraft as filmmaking — and discusses his latest work, Plastic Detox, now streaming on Netflix, which takes a hard look at microplastics and their alarming effects on human fertility. The two also range across a broader landscape: adventures, causes for concern, and — perhaps most valuably in these grinding times — reasons for optimism. It's a talk worth diving into. Additional Resources The Plastic Detox — an eye-opening journey into the hidden dangers of plastic in our homes. When six couples embark on a plastic detox within their homes, it changes their families forever. This eye-opening documentary explains what microplastics and their chemicals are doing to our health and how we can take matters into our own hands. From hormone disruption that’s fueling a worldwide fertility crisis, to growing rates of cancer, and early heart attack and stroke, this powerful documentary reveals the shocking science behind plastic’s impact on human life.
