Mongolia from the Ground Up: COP17 Desertification
What is desertification, why is land degrading around the world, and what can Mongolia teach us about the causes? In Part 1 of Green Frequency’s coverage of UNCCD COP17 in Ulaanbaatar, host Clark Marchese explores the science and politics of land degradation, from the origins of the UN Convention to Combat Desertification and Land Degradation Neutrality to the pressures facing Mongolia’s vast grasslands.Featuring audio from inside COP17 and reporting from Mongolian journalist Turmunkh Gongorjav, the episode examines climate change, drought, overgrazing, mining, urbanization, coal and the growing demand for critical minerals. It also asks a deeper question: whose knowledge counts when governments decide why land is degrading?From Fiji’s coastal farmland to Mongolia’s rangelands, this episode explores how land degradation looks different around the world, why local and Indigenous knowledge matters, and how the way we diagnose environmental problems shapes the solutions we pursue. Part 2 turns to sustainable land management, science and technology, finance, and the political outcomes of COP17.Episode Guest: Turmunkh GongorjavRead Turmunkh Gongorjav’s article hereInterview translated and recorded by Nomin Byambatsogt Explore the Pine Forest Media digital ecosystem on our websiteFollow us on Social Media @pineforestmediaCover 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 Hosted on Acast.

What Does Ocean Technology Need From Us?
Ocean technology cannot operate alone. Nicolas Pade, executive director of the European Marine Biological Resource Centre, joins Green Frequency to unpack five policy recommendations emerging from Blue Tech Europe 2026. We explore technological sovereignty, strategic procurement, collaboration between academia and industry, usable ocean data, market demand and the skills needed to sustain ocean-observation systems. Although developed for Europe, many of these questions apply wherever science must become lasting public infrastructure. And we ask what happens when what markets consider viable is not necessarily what society considers valuable.This is a companion to the Oceanography episode, What Do We Need From Ocean Technology?Episode Guest: Nicolas PadeVisit the EMBRC website or follow the EMBRC on LinkedInListen to Oceanography on Spotify or Apple PodcastsExplore the Pine Forest Media digital ecosystem on our websiteFollow us on Social Media @pineforestmediaCover 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 Hosted on Acast.

Night at the Natural History Museum
What happens behind the exhibits at a natural history museum? At Te Papa Tongarewa, the Museum of New Zealand, millions of specimens form a scientific record stretching across species, ecosystems, and generations. In this episode of Green Frequency, Clark is joined by deep-sea researcher and curator of fishes Dr. Thom Linley to explore what those collections are actually for.We find out why researchers sometimes need to borrow a shark, how curators decide what to preserve for scientists a hundred years from now, and how technologies like micro-CT scanning, hyperspectral imaging, and machine learning are changing what we can learn from specimens collected decades ago. Along the way, we encounter snailfish, bioluminescence, colossal squid, the world's friendliest "meat library," and a much bigger question: what does it mean for a museum to preserve the memory of a changing natural world?Episode Guest: Dr. Thom Linley Listen to the Deep Sea PodcastAnd Dr. Linley’s episode on Oceanography, What is the Deep Sea Even Like?Visit the Te Papa Tongewera Museum website Review Dr. Linley’s publications on Google ScholarExplore the Pine Forest Media digital ecosystem on our websiteFollow us on Social Media @pineforestmediaCover 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 Hosted on Acast.

Coffee and Cocoa: Global Warming and Geoengineering Scenarios
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.Episode Guest: Dr. Nina GrantRead Dr. Grant’s dissertation and watch a short video explainer Review Dr. Grant’s other publication on Google ScholarConnect with Dr. Grant on LinkedIn or visit Dr. Grant’s websiteLearn more about SAI at solargeo.org Green Frequency Ep. 1: Climate change | Where are we now?5 episode of Oceanography on marine climate intervention: mCDR: Can the Ocean Store Our Carbon for Centuries?Marine Cloud Brightening: Can Brighter Clouds Cool the Planet?Stratospheric Aerosol Injection: Should We Reflect More Sunlight?A Natural Experiment in the Sky: Shipping, Clouds, and ClimateSolar Geoengineering: Who Gets to Decide?Explore the Pine Forest Media digital ecosystem on our websiteFollow us on Social Media @pineforestmediaCover 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 Podcast

What Are We Going to Do About These Heat Waves? Lessons from India
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.
