The History of Climate Cycles (and the Woolly Rhino) Explained
Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

Is an Ice Age Coming?
We're living in a brief window of time where our planet isn't frozen underneath a giant layer of glaciers. How much longer will the moderate climate that we've come to know as "normal" continue? This episode looks at how the changes in...

Understanding Climate Part 1: Orbital Variations and the Sun
With the scale of ecology now understood, we can start to look at one of the most important concepts in ecology, climate. What is climate? How does it differ from weather? How does climate change over time and why? Let's do a deep dive now!
