Climate model

Climate models are like special computers that help scientists understand how the weather and the Earth's climate might change in the future.

Let's say you're baking some cookies and you want to know how long they'll take to cook. You might look at the recipe and think about the heat of your oven, the size of your cookies, and how many you're baking, right? That's kind of what climate models do – they take in lots of information about different parts of the Earth's systems (like the atmosphere, oceans, and land) to figure out what might happen to the climate in the future.

Scientists put lots of data into the climate models – things like temperature measurements, air pressure readings, how much sunlight is coming in, and even how the Earth's surface looks (like cities, forests, and oceans). These models use equations and math to simulate how all these different pieces will interact with each other over time.

But, just like how you might not always make perfect cookies, the climate models aren't always perfect either. They're just predictions, and so scientists use them to get a general idea of what could happen to the climate in the future.

By using these climate models, scientists can help us understand how climate change might affect the planet, like how much sea levels might rise or how hot it might get in certain areas. They can also help us figure out ways we can try to stop climate change from getting worse.
