Welcome to Our Planet Earth, a podcast exploring the hidden engines of our planet Earth
We dig into the forces that shape this planet, from kimberlite volcanoes and monster waves to earthquakes that behave like pinball machines. We’ll go deep under the sea, talk about Earth’s last wilderness, and zoom way out to uncover mysteries keep scientists awake at Night
In this episode, we descend a mile below the South Dakota soil into the Sanford Underground Research Facility, the deepest underground science laboratory in the United States.
In these pitch-black, silent tunnels, researchers Moh El Naggar and Yamini Jangir went fishing for a new kind of life in a rusted pipe leaking ancient water.
What they discovered wasn't a creature that eats sugar, fat, or anything we traditionally define as food. Instead, they found microbes that feed directly on pure, streaming electrons.
We pull apart the fascinating evolutionary history of these "exoelectrogens"—bacteria that survive in oxygen-free environments by literally exhaling electrons onto solid rocks.
We trace the story back to the 1980s, when scientist Kenneth Nealson first proposed this impossible idea and met a wall of scientific skepticism.
Finally, we explore the spectacular biological machinery discovered in 2006 that makes this trick possible: conductive, metal-bearing proteins called c-type cytochromes that act like a string of pearls, forming a literal microscopic wire across cell membranes to dump or pull electricity without breaking the cell's barrier.

Race to Protect Glacier Ice Records
In this episode, we explore the high-stakes race against time to rescue the Earth's disappearing climate archives.
Deep within frozen mountain peaks, glaciers trap literal time capsules: ancient air bubbles that preserve centuries-old greenhouse gases, windblown Saharan dust, and heavy water isotopes that read like a historical thermometer.
It’s a localized record of human civilization so precise that Alpine ice cores can track the intense lead pollution from ancient Roman silver smelting, followed by a dramatic drop in atmospheric soot when the Black Death brought European industry to a grinding halt.
But this library is on the verge of self-destruction. Rising global temperatures aren't just melting the ice; they are scrambling the data.
We look at the insidious process of meltwater percolation, where warming summer seasons turn pristine firn zones into wet slush, bleeding chemical history across centuries and fusing distinct annual layers into a chaotic chronological mess.
From the Swiss Alps to the Yukon territory, we follow the glaciologists scrambling to drill and preserve these frozen pages before the climate erases them forever.

Physics of Clouds and Climate Science
In this episode, we tackle the single greatest unknown variable in climate prediction: the delicate and contradictory physics of clouds.
By the end of 2024, global surface temperatures shattered all previous records, pushing hundreds of zettajoules of extra heat energy into our oceans—a staggering reservoir of power altering weather systems worldwide.
Yet, right above our heads sits a microscopic feedback loop that could decide exactly how fast our world continues to warm.
We look inside the microphysics of cloud formation to understand how altitude changes everything.
While low-hanging marine clouds act as brilliant solar shields, high-altitude ice clouds function as planetary heaters. We dive into worrying 2024–2026 satellite data showing that our low cooling shields are actively shrinking, and that global warming is shifting when clouds form, causing daytime shields to dissipate while nighttime heat blankets remain trapped.
Finally, we confront a glaring bias uncovered by researchers in 2025 that threatens to dismantle one of meteorology's greatest hopes for a natural brake on global warming.
