What happens when nature’s recycling system slows almost to a stop? In this episode of The Climate Translation , Dr. Mac explores the hidden science of peatlands, the waterlogged landscapes where dead plants can remain only partially decomposed for thousands of years. Listeners will learn how oxygen, microbes, moss, and water interact to create peat, preserving ancient pollen, wildfire records, an...

If the rest of the oceans are warming, why isn't the Antarctic Ocean? In this episode of The Climate Translation , Dr. Mac steps back from individual studies and headlines to explore one of the most perplexing climate mysteries of the modern era. Using decades of satellite observations, ocean measurements, and advanced computer modeling as a real-world case study, he explains how an atmospheric ch...

How do scientists know the climate is changing? In this episode of The Climate Translation , Dr. Mac steps back from individual studies and headlines to explore how researchers monitor the health of our planet. Using the latest global climate report from June 2026 as a real-world case study, he explains how organizations like NOAA and the Copernicus Climate Change Service build a comprehensive pic...

Can humans build a forest, or can we only plant trees? In this episode of The Climate Translation , Dr. Mac explores one of the largest ecological restoration projects in history: China's Great Green Wall. Stretching thousands of miles across northern China, this ambitious effort was designed to slow the spread of desertification, reduce dust storms, and restore degraded landscapes. Drawing on sat...

If the Earth is getting warmer, why can’t we simply cool it back down? In this episode of The Climate Translation , Dr. Mac examines a recent climate modeling study that explored two different approaches to solar geoengineering. While both methods cooled the planet in computer simulations, they produced surprisingly different effects on one of Earth’s most important climate systems: El Niño. From...

If your summer has felt fairly normal, even pleasant, does that mean climate change has somehow taken a year off? In this episode of The Climate Translation , Dr. Mac uses the contrasting weather of the summer of 2026 to explore one of the most misunderstood ideas in climate science: the difference between weather and climate. From a rainy, green summer in Georgia to dangerous heat waves across Eu...

Earth may be the Blue Planet, but surprisingly little of its water is available for human use. Much of the world's freshwater is stored in glaciers, mountain snowpack, and underground aquifers that act like natural savings accounts when rivers, farms, cities, and ecosystems need it most. In this episode of The Climate Translation , Dr. Mac explores where Earth's freshwater actually comes from, how...

Most of us think of hail as one of nature’s simpler weather hazards. But the science behind hail is surprisingly complex, and new research suggests that a warming atmosphere may be changing where and when some of the world’s most severe hailstorms occur. In this episode of The Climate Translation , Dr. Mac explores how powerful thunderstorms create hailstones that can grow from tiny ice pellets in...
