Green Frequency – Détails, épisodes et analyse

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.

Water 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.

Climate 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.

Where 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.

We 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 action
• How power, culture, and politics shape environmental decision making
• What science-policy-society interfaces actually look like in practice
• Why listening may be just as important as producing evidence

At the center of it all is a simple idea: Science can help us understand the world, But changing it requires something more human.

Colonial law helped shape modern deforestation. Legal historian Mariana Dias Paes explains how 19th-century property law, land dispossession, and colonial legal systems accelerated rainforest destruction in Brazil’s Atlantic Forest and continue to influence environmental conflicts today. This episode of Green Frequency explores colonialism, Indigenous land rights, private property, environmental history, and the legal foundations behind modern climate and conservation crises across the Atlantic world, including the Amazon and Congo rainforests. Recorded live at The American University of Paris, the conversation connects legal history to present-day environmental governance, climate justice, and biodiversity loss. Full video version with presentation slides and maps available on YouTube.

How many species are there on Earth? Marine biologist and taxonomist Manuel Caballero Gutierrez explains how scientists estimate global biodiversity, discover new species, and why humanity may currently know only around 25% of the life forms that exist on this planet. This episode of Green Frequency explores taxonomy, ocean exploration, extinction, climate change, and the long scientific process of naming and cataloguing species. From deep-sea expeditions and DNA analysis to museum archives and biodiversity conservation, the conversation reveals why understanding life on Earth is essential for protecting ecosystems and human society alike. Recorded live at The American University of Paris, with the full presentation video and slides available on YouTube.

Bioluminescent water that cameras can barely capture.

Environmental filmmaker and researcher Dr. Isabelle Carbonell explores Bio Bay in Vieques, Puerto Rico, one of the brightest bioluminescent bays on Earth, to ask a bigger question: what happens when nature resists visibility? This episode examines environmental filmmaking, underwater cinema, ocean representation, bioluminescence, and the limits of visual storytelling. The conversation also explores wonder, environmental justice, colonial history, military contamination in Vieques, and how artists help shape the way we emotionally encounter the natural world. From deep sea cameras to experimental film theory, this is a thoughtful exploration of perception, ecology, and what it means to experience something that cannot be fully captured on screen.

Mountain gorillas were once on the brink of extinction. Today, they are the only great ape whose population is increasing. In this season finale of Green Frequency, Gorilla Doctors Chief Communications Officer Amy Bond joins Dr. Elena Berg for a conversation about conservation, climate anxiety, cooperation, and environmental agency. Recorded live at The American University of Paris, the discussion explores what gorilla conservation can teach us about long-term change, uncertainty, and how humans respond to overwhelming global challenges. The episode also reflects on themes from across the season, including biodiversity, environmental storytelling, interdisciplinary thinking, and the importance of staying engaged in the face of ecological crisis. A thoughtful conversation about fear, hope, and the possibility of meaningful environmental action.
