Climate models can be useful, especially when you use them to predict events that have already happened (e.g you have the data to either show the model is correctly forecasting the past event, or you have the data to show the model has gone awry.) Theoretically, if your model can predict past events correctly, you can then apply it to present and future events and get reasonable results. Theoretically... PS. Weather forecasting is pretty accurate these days. I'd take bets on 7 day forecasts from the NWS. Source: Meteorology degree.
