Abstract/Summary

Weather is something that we all experience and when weather is averaged over a long time, it is called climate. The climate is changing and it is because of us. Climate change is already being experienced around the world and will affect everyone. Some scientists and politicians are now calling this a time of climate crisis [1]. For example, communities living close to coastlines may have to move due to sea-level rise. We will have to work together in our communities to understand the problem and to try to minimize its effects on the natural world. As the climate changes, it is not just the air that changes, but other parts of the world, too. In this article we will explore how and why we use computers to build model worlds. We call these climate models. You can help us experiment with climate models and I will tell you how.
