Changing Water Cycle
Changes in the hydrological cycle as a consequence of climate and land use drivers are expected to play a central role in governing a vast range of environmental impacts. At the same time, predictions of water-related variables show very high uncertainty; for example, as shown in the recent Intergovernmental Panel on Climate Change fourth assessment report (IPCC AR4).
The Changing Water Cycle programme will develop an integrated, quantitative understanding of the changes taking place in the global water cycle, involving all components of the earth system, improving predictions for the next few decades of regional precipitation, evapotranspiration, soil moisture, hydrological storage and fluxes.
