"Possible or probable?," by Myles R. Allen. Nature, 18 September 2003, page 242.

Uncertainty in climate models results in a range of possible outcomes that can't all be planned for. The climate-research community is attempting to assign probabilities to climate forecasting so that preparations can be made for the more realistic scenarios. Toward that end, the community wants to assemble information from the simulations of various models. Care must be taken when searching for a representative sample of models because models can be very similar. Also the models often operate on the same data set so that assigning weights to the selected models isn't a straightforward process either. So many climate simulations are needed that climate researchers are now using idle desktop processing time (information here).
