Climate modeling 101: Explanations without equations

Richard B. Rood, Andrew Gettelman | January 1, 2016
Summary

Climate scientists tell us it’s going to get hotter. How much it rains and where it rains is likely to shift. Sea level rise is apt to accelerate. Oceans are on their way to becoming more acidic and less oxygenated. Floods, droughts, storms, and other extreme weather events are projected to change in frequency or intensity.

But how do they know what they know?

For climate scientists, numerical models are the tools of the trade. But for the layperson — and even for scientists in other fields — climate models can seem mysterious. What does “numerical” even mean? Do climate models take other things besides the atmosphere into account? How do scientists know if a model is any good? *

Two experts in climate modeling, Andrew Gettelman of the National Center for Atmospheric Research and Richard Rood of the University of Michigan, have your answers and more, free of charge. In a new open-access book, “Demystifying Climate Models,” the pair lay out the fundamentals. In 282 pages, the scientists explain the basics of climate science, how that science is translated into a climate model, and what those models can tell us (as well as what they can’t) — all without using a single equation.

*Find the answers on pages 8, 13, and 161, respectively, of the book.
