 Hi students, welcome to module three on climate models. I grew up in London back in the 1960s and weather forecasts were always wrong. They would predict a storm, it would be perfectly sunny. They would predict sunny weather and there would be a storm. They were always wrong. Now we're at a time when weather prediction is really good and that's because the computer side of the models is very strong and very advanced and we're getting much better at predicting climate in the future as well. So in this module you'll learn about how CO2 levels and forecasted levels of CO2 drives climate models. The amount of CO2 in the atmosphere will definitely be related to the temperature in the future as well as the global rainfall in the future, storm tracks and storm intensity in the future, fire forecasts in the future and sea level rise. And what we're going to learn about in this module is how different levels of CO2 that are controlled by human activity in the future will definitely be able to be will definitely be used to predict temperature, rainfall, hurricane intensity as well as sea level rise. I think you're going to learn a lot about this module, how it's important for your future and I hope you enjoy it.
