| Drinking Water: Why Sustainability Is So Complicated | 06 May 2026 | 00:28:14 | |
Drinking water reveals sustainability's complexity. Environmental scientist and water sommelier Dr. Elena Berg uses bottled water to show why environmental choices rarely divide neatly into good and bad. She traces how geology and mineral content create differences among waters, contrasts multinational bottlers with smaller single-source producers, and examines plastic waste, freshwater access, infrastructure, and environmental justice. The conversation also asks what sustainability means when every product carries an environmental cost and warns against treating it as a label or completed checklist. From tap water and water tasting to the stewardship practiced by some small water farmers, this episode offers an interdisciplinary environmental science case study in how context changes both the problem and the available response.

| What Does Climate Justice Actually Mean? | 29 Apr 2026 | 00:26:38 | |
Climate change is never socially neutral. Political scientist Dr. Rebecca Marwege explains climate justice by examining who caused the crisis, who experiences the greatest harm, and who has the resources and power to respond. Cases involving the Lebu fishing community in Senegal and Far Rockaway after Hurricane Sandy show how climate adaptation, displacement, rebuilding, and even the ability to remain at home are shaped by inequality. The episode distinguishes climate justice from environmental justice and warns against reductionism, inverse reductionism, and technological solutionism. It makes the case for interdisciplinary research that joins environmental science with political, social, and ethical analysis so that climate policy protects communities instead of reproducing existing injustice.

| Climate change | Where are we now? | 22 Apr 2026 | 00:27:57 | |
Climate progress is real, but nowhere near enough. In the first episode of Green Frequency, climate scientist Dr. Claudio Piani joins student activist Averie Gannon to assess climate change in 2026 through evidence rather than denial or catastrophe. They examine global and per-capita emissions, areas of progress in the United States and Europe, the falling cost of renewable energy, and what current national commitments mean for the Paris Agreement. The conversation explains why the 1.5-degree target is probably out of reach, why that does not make climate action futile, and why every tenth of a degree still protects lives and ecosystems. A grounded introduction to climate science, climate policy, and the difficult work still ahead.

| Science Can’t Change the World on Its Own | 13 May 2026 | 00:25:10 | |
Science alone does not make environmental change. Amanda Harding and Sarah Glavan of Convene explore the missing space between research, environmental policy, and the decisions people make inside real systems. Using food systems and the EAT-Lancet Commission as a case study, they explain deliberate dialogue and science-policy-society interfaces: structured spaces where researchers, farmers, fishers, Indigenous communities, health professionals, policymakers, and consumers can work through disagreement and power. The episode shows why ecological research cannot simply be handed down as instructions, why lived experience is also a form of knowledge, and how listening can help turn evidence into action. A practical look at what climate solutions require once the science is already available.

| Colonial Law and Deforestation: When Laws Destroy Nature | 20 May 2026 | 00:27:41 | |
Colonial law helped build modern deforestation. Legal historian Dr. Mariana Dias Paes traces how nineteenth-century property law created mechanisms for land dispossession and environmental destruction in Brazil's Atlantic Forest. Her research connects that history to the Amazon and Congo rainforests, where colonial legal systems continue to shape land disputes, court decisions, Indigenous rights, and conservation. Rather than treating environmental law only as a solution, the episode examines how law helped create the conditions for rainforest loss and why those structures persisted after independence. This is an environmental history of private property, colonialism, and the legal architecture still influencing environmental policy, environmental justice, and forest conservation today.

| How Many Species Are There on Earth? | 26 May 2026 | 00:23:27 | |
Most of Earth's species remain unknown to science. Marine biologist and taxonomist Dr. Manuel Caballero Gutierrez explains how scientists estimate global biodiversity and why humanity may currently know only about 25 percent of the species that exist. He walks through taxonomy as scientific detective work, from deep-sea expeditions and specimen collection to anatomical study, DNA analysis, museum archives, formal naming, and publication. The episode examines biodiversity loss, why the shortage of taxonomists matters, how scientific knowledge can disappear with individual specialists, and why species may go extinct before humanity knows they exist. An expansive introduction to biodiversity, ocean exploration, and the ecological research that conservation depends upon.

| Environmental Filmmaking and the Limits of Seeing | 03 Jun 2026 | 00:27:53 | |
Some environmental wonders resist the camera. Environmental filmmaker and cinematographer Dr. Isabelle Carbonell takes listeners to Bio Bay in Vieques, Puerto Rico, where dense concentrations of dinoflagellates create brilliant bioluminescence that cameras struggle to capture. That technical failure becomes a question about visibility, wonder, embodiment, and whether an imperfect image can open other ways of knowing nature. Carbonell also situates the bay within Vieques's history of colonial extraction, United States military occupation, contamination, and slow environmental violence. The result is an exploration of environmental filmmaking and visual storytelling that asks what environmental communication loses when it values only spectacular images, and what environmental justice can reveal about the things that remain unseen.

| Mountain Gorilla Conservation: The Work Ongoing | 09 Jun 2026 | 00:26:23 | |
Mountain gorilla recovery proves change is possible. Gorilla Doctors Chief Communications Officer Amy Bond joins environmental scholar Dr. Elena Berg to examine how long-term conservation succeeds and how people remain engaged when progress is slow and uncertain. Bond explains how Gorilla Doctors provides veterinary care to eastern gorillas in Rwanda, Uganda, and the Democratic Republic of the Congo while keeping animals with their families in the wild. The conversation connects ecological research, cooperation, communication, and sustained institutional work to the recovery of mountain gorillas, the only great ape whose population is increasing. It also explores climate anxiety, environmental agency, hope, and the emotional discipline required to continue working without guarantees. A conservation story about measurable progress and the work that must continue.

| What Are We Going to Do About These Heat Waves? Lessons from India | 04 Aug 2026 | 00:38:48 | |
Heat waves are arriving earlier, lasting longer, and reaching further into daily life. So what do we do before the next one arrives? Climate researcher Kartikeya Bhatotia joins Green Frequency to explain what decades of research and experimentation in India can teach a rapidly warming world. Drawing on Critical Perspectives on Extreme Heat in India, he explores why heat is more than a temperature, how housing, labor, gender, health, and access to cooling shape exposure, and why adaptation cannot be reduced to air conditioning or emergency alerts. The conversation moves through India’s pioneering heat action plans, anticipatory finance, passive cooling, parametric insurance, and the idea of a “cool economy.” India emerges not only as a country facing extreme heat, but as a source of adaptation knowledge. These strategies do not replace a fossil fuel phaseout; they show how governments can protect people from the heat already here, before the worst arrives.

| Coffee and Cocoa: Global Warming and Geoengineering Scenarios | 17 Aug 2026 | 00:48:12 | |
What would happen to coffee and cocoa if humans deliberately tried to cool the planet? Atmospheric scientist Dr. Nina Grant joins Green Frequency to explain stratospheric aerosol injection, or SAI, a proposed form of solar geoengineering that would introduce reflective particles into the upper atmosphere. Drawing on climate and crop modeling for cocoa in Ghana and coffee in Brazil, Nina explains why lowering global temperatures may not be enough. In her modeled scenarios, SAI softened projected losses but did not return either crop to present-day yields. The conversation opens the black box of climate models, explores the importance of rainfall and agricultural management, and reveals how one planetary intervention could produce very different outcomes around the world. It also confronts the much larger questions surrounding ozone loss, termination shock, climate justice, and governance. SAI would not remove carbon dioxide or replace phasing out fossil fuels. But as scientific and political interest grows, understanding what it could change, whom it might help, and who gets to decide is becoming a public question.
