Once a climate model is set up, it can be tested via a process known as “hind-casting.” This process runs the model from the present time backwards into the past. The model results are then compared with observed climate and weather conditions to see how well they match. This testing allows scientists to check … Ver mais Models help us to work through complicated problems and understand complex systems. They also allow us to test theories and solutions.
