Figure TS-3: The pattern
of changes in runoff largely follows the pattern of simulated changes in precipitation,
which varies between climate models. The modeled increases in runoff shown in
both maps [(a) HadCM2 ensemble mean and (b) HadCM3; see Section
4.3.6.2 of Chapter 4 for discussion of models and scenarios
used] for high latitudes and southeast Asia, and decreases in central Asia, the
area around the Mediterranean, southern Africa, and Australia are broadly consistent—in
terms of direction of change—across most climate models. In other parts of
the world, changes in precipitation and runoff vary between climate change scenarios.
