About the Figure

Each marker in the scatter plot represents an individual GCM's future projections for the future year indicated with respect to the historical years 1971-2000 for the indicated variables in the indicated season.

The future projection is calculated by averaging the yearly values of the variable's average(or sum) over the indicated season. The average over 30 years of data gives an indication of the climate for that variable in the future period.

The scatterplot of projections from all models in the Integrated Scenarios project gives a range of projections under each future scenario. The multi-model mean from each future scenario may be useful in comparing the scenario results. It may be useful to identify individual models that are close to the multi-model mean projection or which represent extremes in the span of the projection space.
