Climate models are presumed to be far too complicated for the layman to understand so they are left to the experts. However, the models save lives and valuable infrastructure. The complicated lines of code make predictions about future weather patterns. Just a few decades ago weather could not be forecast for two days ahead. Currently, five day forecasts are common and they are reliable. Even seasonal outlooks are treated as valid. For examples, we have been told in Queensland that there will be a wet summer. The all-seeing weather bureau is counted on to provide information about strong winds, hailstorms, cyclones and even the direction of forest fires. To get an accurate prediction, up to date and correct data must be fed into the models. Computers are getting larger all the time and more complex models are being formulated. This is a complex job. Scientists need to draw on many specialized fields in physics, mathematics and computer science. No university offers a course te...
