Time-variable gravity measurements from the Gravity Recovery and Climate Experiment
(GRACE) and GRACE Follow-On (GRACE-FO) missions have opened up a new avenue of …

Freshwater availability is changing worldwide. Here we quantify 34 trends in terrestrial water
storage observed by the Gravity Recovery and Climate Experiment (GRACE) satellites …

Groundwater resources are vital to ecosystems and livelihoods. Excessive groundwater
withdrawals can cause groundwater levels to decline,,,,,,,,–, resulting in seawater intrusion …

The rate of global-mean sea-level rise since 1900 has varied over time, but the contributing
factors are still poorly understood. Previous assessments found that the summed …

Abstract Changes in evapotranspiration (ET) affect water availability and ecosystem health.
Higher evaporative demand during drought acts to increase ET, but droughts also reduce …

Abstract The Greenland Ice Sheet has been a major contributor to global sea-level rise in
recent decades,, and it is expected to continue to be so. Although increases in glacier flow …

Ice losses from the Greenland and Antarctic Ice Sheets have accelerated since the 1990s,
accounting for a significant increase in global mean sea level. Here, we present a new 29 …

Accurate quantification of global land evapotranspiration is necessary for understanding
variability in the global water cycle, which is expected to intensify under climate change …

Groundwater provides nearly half of irrigation water supply, and it enables resilience during
drought, but in many regions of the world, it remains poorly, if at all managed. In heavily …

WaterGAP is a global hydrological model that quantifies human use of groundwater and
surface water as well as water flows and water storage and thus water resources on all land …
