Global water availability and its distribution under the Coupled Model Intercomparison Project Phase Six scenarios

Abstract Changes in the hydrological cycle have widespread consequences and remain uncertain under climate change. We analyse the changes in major water components of the hydrological cycle, that is, precipitation ( P ), runoff ( Q ), evapotranspiration ( E ), precipitation minus evapotranspiration ( P  − E ), and terrestrial water storage ( S ), and quantify the uncertainties across the 21 st century with Phase Six of the Coupled Model …
