Technical information on long-range forecasting

In contrast to weather forecasts, long-range prognoses on climatic evolution are naturally beset by a high degree of uncertainty. Nevertheless, predictions can be made with regard to average values. This is done by running model simulations on high performance computers in order to quantify the range and probability of possible climatic conditions.
