Down To Earth: A podcast for Geoscientists by Geoscientist

Welcome to “Down to Earth”, a 30-minute podcast about innovative geoscience and the incredible people behind it. Each week, we host a different guest to talk about science, careers, and passions. From stories about meeting their idols, to investigating their science superpowers, and all the fascinating research and engineering projects in between, Down to Earth is sure to become your quick and compelling catch-up on the people and the work in geoscience. This podcast is presented by the IEEE Geoscience and Remote Sensing Society.

  1. SEASON 6 TRAILER

    Down to Earth Season 6: AI4EO Trailer

    Imagine a world where scientists can predict natural disasters before they strike, where we can monitor the health of our planet in real-time, and where we can uncover the secrets of Earth's hidden resources. Welcome to the future of geoscience, where AI is revolutionizing our understanding of the planet! In this season of Down to Earth, we’re exploring the uncharted territories of AI in geoscience, from the groundbreaking capabilities of supercomputing to the revelatory insights of Geospatial Foundation Models. As AI challenges and reshapes our understanding of Earth's systems, it also presents some complex, and sometimes unexpected, cultural and social implications. Through deep conversations with visionaries, innovators, and researchers, we'll explore the promises and pitfalls of this technological revolution and we’ll dare to ask the ultimate question: Will AI unlock the secrets of our planet, or, will it lead us down a precarious rabbit hole, we have yet to imagine? Find out this fall on season 6 of Down to Earth: A Podcast FOR Geoscientists BY Geoscientists!

    S05E08 Down to Earth: Food Security

    From its role in sustaining and nurturing our bodies to its cultural and social significance, food is a key component of human life. It’s also in serious jeopardy due to climate change. In this episode, we speak with Dr. Inbal Becker-Reshef about her work in the field of food security. Together, we delve into the critical role of geospatial technologies in monitoring agricultural systems, assessing crop health, and predicting yield fluctuations through programs including the GEOGLAM Crop Monitor for Early Warning initiative. Through our discussion, Dr. Becker-Reshef teaches us how geoscientific approaches can shape the future of food security and sustainability.

    S05E07 Down to Earth: Water Resources

    According to the UNU Institute for Water, Environment and Health, water-related disasters (WRDs), including floods and droughts, account for 90% of natural disasters. These disasters result in significant loss of life each year, not to mention the billions spent on managing and rebuilding afterwards. As the global water crisis continues to grow, so too does our need for tools, techniques, and policy that will help us more effectively predict, respond to, and prevent WRDs. In this episode, we speak to Dr. Hamid Mehmood, Economic Affairs Officer with United Nations ESCAP to find out how we can address WRDs with technology.

    S05E06 Down to Earth: Sea Ice

    What’s the difference between glaciers and sea ice and why do we need to be studying sea ice to better understand climate change? In this episode, we speak to two experts who study sea ice in the arctic and antarctic respectively. Dr. Anja Frost and Dr. Sven Jacobsen share their concerns about the pressing issue of the Arctic’s vanishing sea ice, the need to understand the relationship between ocean waves and sea ice depletion, and how remote sensing techniques are improving our understanding of Arctic sea ice changes. Together, both Anja and Sven use their expertise to support ships travelling through the arctic. Their research helps to optimise ship navigation, reduce emissions, and improve the technologies and processes for studying sea ice using remote sensing.

    S05E05 Down to Earth: Glaciers

    As far back as 2014, Dr. Eric Rignot, specialist in glaciology, has been informing us that some of our glaciers are melting faster than we can save them. Yet, this knowledgeable and passionate scientist continues to advocate for hope. In this episode we’ll dive deep into the meltwater to not only understand glacier behaviour, but how we can proactively deal with the results.

    S05E04 Down to Earth: Aerosols

    Methane is a dangerous gas has more than 80 times the warming power of carbon dioxide over a 20-year period. Methane is a major contributor to global warming. But the good news is, unlike CO2, methane has a very short atmospheric lifespan – around 10 years to be exact. In this episode, we speak with Dr. Ritesh Gautam who is an expert in atmospheric sciences, explores the impact of methane as a potent greenhouse gas and shares news of a new satellite mission that will help us cut methane emissions in half by 2030!

    S05E03 Down to Earth: Permafrost

    Whenever we think of greenhouse gases, carbon dioxide is top of mind. But a more nefarious gas is gaining notoriety: Methane. Not just restricted to agricultural emissions, methane is also found in the Earth’s permafrost, which is melting at an increased rate due to climate change. It’s a vicious cycle that we seriously need to interrupt. So in this episode, we delve into the critical issue of permafrost thaw and its implications for methane release with Dr. Annett Bartsch. Dr. Bartsch, a leading researcher of permafrost, shares the satellite observations and modeling techniques used to track permafrost thaw and highlights the consequences of methane emissions on our climate system.

    S5E02 Down to Earth: Wetlands

    Wetlands are the Earth’s greatest natural carbon stores, however, since 1900, we have lost 64% of our wetlands due to both human activity and climate change. Coastal wetlands and deltas–wetlands that form as rivers–are particularly vulnerable due to their position at the land-sea interface and many are, in fact, sinking. In this episode, we speak to Dr. Marc Simard about the crucial role of wetlands in climate regulation and adaptation. We also dig into his Delta-X project to look at how he and his team are combining remote sensing and in situ measurements to understand how the Mississippi River Delta is growing and sinking, and how we can apply this research to protecting deltas around the world.
