This presentation is designed to give middle and high school students a basic understanding of what climate models are and how they function. The evolution of the resolution and complexity of climate models from the mid 1970's to the present is discussed, as are the changes in data set size. Methods for testing climate models against a variety of benchmarks such as historical climate changes or seasonal changes are explained. The presentation shows that various climate models have different strengths and weaknesses and that the average of a number of models produces the best results. Several key issues arising from global climate change are highlighted followed by suggestions for student actions that will help them limit their carbon dioxide emissions.
