Modeling Our Climate

Climate change is a term we often hear. But what is it and how is it modeled?

When we need to study something in science that is too large or complex to easily work with, we’ll often make a model of it in order to recreate it in a simpler way.

You might not realize it, but we actually use models all the time in our everyday life. They can be static and representational, like the New York City subway map – or they can be used to make predictions of dynamic systems, like a weather forecast or the ups-and-downs of the stock market.

Even our understanding of climate change, a phenomenon on the tip of everyone’s tongues, is based on predictions made by a model.

The Global Climate Model, otherwise known as the GCM, is a hugely complex system. It’s so complicated that its calculations require the work of multiple supercomputers located all around the world.
