FIGURE 2.16
Projected changes in the total global precipitation from 2000 to 2100 relative to (1980–1999)
average. Colored lines represent different climate models and the black line represents the
average for all the models. These projections were made using three IPCC scenarios A2 (top),
A1B (middle), and B1 (bottom).
