In this step you'll learn about the climate models used to understand the impact of climate change. These models divide the Earth's atmosphere into a grid of hundreds of thousands of cells and stacks like a skyscraper. The models then calculate how energy, air, and water vapor flow through each cell over a given time period. They also consider the atmosphere's behavior over years and years, simulating either the world as it is or the world as it might be."
