Fig. 2. Runoff and economic impact uncertainty.

Uncertainty over time plots of the four chosen basins. Values are taken relative to the 2015 baseline. Uncertainty prior to 2015 is illustrative only. The scenario group shown in A–D has the lowest mean climate-induced economic impact uncertainty over time out of the 600 groups. The scenario group shown in E–H has the highest mean climate-induced economic impact uncertainty over time. In most scenarios, runoff uncertainty is amplified by the human system, leading to higher uncertainty in economic impact.
