Figure 8. Differences between mid-Holocene and present-day mean annual precipitation (MAP) [mm/y] in North Africa. The line in each box depicts the median value, the box shows the 25 to 75 percent range, and the whiskers show the total range of values. The light blue box indicates reconstructed MAP differences; the purple, dark-blue, and green boxes depict simulated MAP differences from atmosphere-only models in which present-day SST were prescribed: atmosphere-ocean models, and atmosphere-ocean-vegetation models, respectively.
