It’s one of the most famous, and controversial, graphs in climate science. But what does the “Hockey Stick” actually show?

In this episode of The Climate Translation, Dr. Mac unpacks the iconic temperature graph that illustrates how Earth’s climate changed slowly for centuries before accelerating dramatically in the modern era. He explains how scientists reconstruct past temperatures using natural “proxies” like tree rings, ice cores, and ocean sediments, and why multiple, independent lines of evidence all point to the same conclusion.

Along the way, Dr. Mac breaks down the controversy surrounding the graph, why claims that it was “debunked” persist, and how understanding rate of change helps explain why today’s warming is fundamentally different from the past.

If nearly all climate scientists agree, why does it still feel like a 50/50 debate?

In this episode of The Climate Translation, Dr. Mac breaks down what scientific consensus actually means, and why it’s so often misunderstood or misrepresented in public conversations about climate change. Using clear analogies and real-world examples, he explains how consensus forms in science, why outliers get outsized attention, and how a handful of “celebrity skeptics” can distort public perception.

This episode gives you the tools to recognize false balance, understand why expert agreement matters, and talk more confidently about climate science without turning the conversation into a fight.

We live in a world overflowing with climate data, so why does it still feel so hard to believe what’s happening?

In this inaugural episode of The Climate Translation, Dr. Mac explores the disconnect between overwhelming scientific evidence and our very human difficulty processing change at a planetary scale. Drawing on decades of experience as a meteorologist and educator, he breaks down why terms like “parts per million” and “global averages” fail to resonate, and how simple analogies can make the science finally click.

From ice cores to dinner-table conversations, this episode lays the foundation for understanding not just what the climate data says, but why it so often gets lost along the way.
