The geographical patterns of local agreement/disagreement in projected precipitation change remain broadly similar with increased global warming, but the range of uncertainty generally increases . For example, in northeastern Amazonia, the driest projections increase from a 10% decrease at 1.5℃ global warming to a 40% decrease at 4℃ global warming. In comparison, the wettest projections remain at up to a 10% increase. In the far north of North America and Asia, the higher end of projected increases in precipitation extends to approximately 40-60%. A few regions are projected to see a shift in the consensus on the sign of the change. These include parts of the Indian sub-continent where at 4℃ global warming, the projected changes shift to a consensus on increased precipitation ranging between a few percent to over 70%.
