Green Frequency
Green Frequency Trailer
Green Frequency: Earth Radio is an environmental science podcast exploring the research, stories, and decisions shaping our planet.
Each week, we unpack emerging environmental research, hear stories from civil society and the frontlines of conservation, and follow developments in global environmental policy and climate action.
From forests and oceans to courtrooms and conference halls, Green Frequency connects science to the real-world contexts where it is applied across communities, institutions, and global systems.
Hosted by Clark Marchese, founder of Pine Forest Media, the show brings together scientists, journalists, and practitioners from around the world to share knowledge, perspectives, and solutions.
This is Earth Radio. A place to tune in, stay curious, and listen closely.

4. Science Can’t Change the World on Its Own
25:10||Ep. 4We already understand many of the world’s biggest problems. So why are they still unsolved? A lot of the science is in. We know what is driving climate change, biodiversity loss, and pressure on global food systems. But knowledge alone does not create change. Somewhere between evidence and action, people have to make decisions. This episode explores that space.Using food systems as a case study, this conversation looks at what happens when science, policy, and lived experience meet. It asks who gets to shape solutions, how decisions are actually made, and why simple answers often fall short.Featuring Amanda Harding and Sarah Glavan of Convene, the discussion introduces the idea of deliberate dialogue. Carefully designed spaces where farmers, researchers, policymakers, and communities work through complex challenges together. Not by avoiding disagreement, but by working through it.Across this conversation:Why scientific knowledge does not automatically translate into actionHow power, culture, and politics shape environmental decision makingWhat science-policy-society interfaces actually look like in practiceWhy listening may be just as important as producing evidenceAt the center of it all is a simple idea.Science can help us understand the world.But changing it requires something more human.Episode Guests: Amanda Harding and Sarah GlavanVisit the Convene Website to learn more about Deliberate DialogueExplore the Pine Forest Media digital ecosystem on our websiteFind the full-length video on YouTube @PineForestPodsFollow us on Social Media @pineforestmediaHosted by Clark Marchese and Averie GannonAudio Editing by Clark Marchese, Video Editing by Oscar PadulaVideography and Set Design by Le Studio Du PassageCover Art by Laurel WongTheme music by Nela RuizFind some more Pine Forest Media podcasts belowListen to Oceanography on Spotify or Apple PodcastsListen to Plastic Podcast on Spotify or Apple PodcastsListen to South Pole on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts
3. Drinking Water and the Complexity of Sustainability
28:14||Ep. 3Water is simple to drink, but complex to understand. Water is essential to life, yet 2 billion people lack reliable access to clean drinking water. At the same time, millions of tons of plastic waste come from single-use bottles each year. So what actually makes water “sustainable”? Environmental scientist and water sommelier Dr. Elena Berg uses drinking water as a case study to unpack the complexity of sustainability from water sources and mineral content to local infrastructure, plastic use, and global inequality. Learn why not all water is the same, how small-scale “water farmers” approach stewardship, and why simple good vs bad narratives can be misleading. A deeper look at sustainability, environmental decision-making, and the hidden systems behind everyday choices.Episode Guest: Dr. Elena BergListen to Something in the Water on Spotify or Apple PodcastsExplore the Pine Forest Media digital ecosystem on our websiteFind the full-length video on YouTube @PineForestPodsFollow us on Social Media @pineforestmediaHosted by Clark MarcheseAudio Editing by Clark Marchese, Video Editing by Oscar PadulaVideography and Set Design by Le Studio Du PassageCover Art by Laurel WongTheme music by Nela RuizFind some more Pine Forest Media podcasts belowListen to Oceanography on Spotify or Apple PodcastsListen to Plastic Podcast on Spotify or Apple PodcastsListen to South Pole on Spotify or Apple Podcasts
2. What does Climate Justice Even Mean?
26:38||Ep. 2Climate justice explained: beyond emissions and policy. What does climate justice actually mean—and why is it so hard to define? This episode of Green Frequency breaks down climate justice as both a political and ethical challenge, not just an environmental one. Political scientist Dr. Rebecca Marwege explores how climate change reflects global inequalities, from coastal communities in Senegal to post-disaster recovery in New York. The conversation highlights why reducing emissions alone isn’t enough, and how adaptation, access to resources, and decision-making power shape real-world outcomes. Learn why interdisciplinary approaches, bringing together science, policy, and lived experience, are essential, and what can go wrong when they’re ignored. A clear, accessible introduction to climate justice, sustainability, and global climate policy.Episode Guest: Dr. Rebecca MarwegeLearn more about Dr. Marwege’s research on her website Discover the recently published Climate Justice Now, edited by Dr. Rebecca Marwege, Dr. Nikhar Gaikwad and Dr. Joerg SchaeferExplore the Pine Forest Media digital ecosystem on our websiteFind the full-length video on YouTube @PineForestPodsFollow us on Social Media @pineforestmediaHosted by Clark Marchese and Allison ThompsonAudio Editing by Clark Marchese, Video Editing by Oscar PadulaVideography and Set Design by Le Studio Du PassageCover Art by Laurel WongTheme music by Nela RuizFind some more Pine Forest Media podcasts belowListen to Oceanography on Spotify or Apple PodcastsListen to Plastic Podcast on Spotify or Apple PodcastsListen to South Pole on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts
1. Climate Change | Where Are We Now?
27:57||Ep. 1Where does climate change stand in 2026? In this first episode of Green Frequency, we take a grounded look at the state of climate change today. Where progress is being made, where challenges remain, and what the data actually tells us.Featuring a conversation with climate scientist Dr. Claudio Piani and student activist Averie Gannon, this episode explores global emissions trends, the future of the Paris Agreement, and why every fraction of a degree of warming still matters. The discussion moves beyond extremes to offer a more nuanced perspective on climate science, public understanding, and the role of individual and collective action.Green Frequency is an Earth Radio Show that brings together environmental research, frontline stories, and global decision-making. Across this series, we hear from scientists, advocates, and communities around the world to better understand the systems shaping our planet and what it takes to respond to them.This is the beginning of Season 1, The Work Ongoing, a series focused on understanding where we are now and how we move forward.Episode Guest: Dr. Claudio Piani Special thanks to the American University of ParisOur World In Data - CO2 emissions, temperature, and per capita trends.The Scientific American - Global Average Temperature TargetsInternational Renewable Energy Agency - The Cost of Renewable EnergyExplore the Pine Forest Media digital ecosystem on our websiteFind the full-length video on YouTube @PineForestPodsFollow us on Social Media @pineforestmediaHosted by Clark Marchese and Averie GannonAudio Editing by Clark Marchese, Video Editing by Oscar PadulaVideography and Set Design by Le Studio Du PassageCover Art by Laurel WongTheme music by Nela RuizFind some more Pine Forest Media podcasts below:Listen to Oceanography on Spotify or Apple PodcastsListen to Plastic Podcast on Spotify or Apple PodcastsListen to South Pole on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple PodcastskVGqe9JmZjbPts6IRu3v
