Abstract
Aquifer residence times are commonly used to make inferences about groundwater renewability. However, the link between aquifer residence times and hydraulic response times, which control groundwater storage changes, remains unclear. Here we show that water levels in many aquifers containing fossil groundwater are controlled by modern climates. Evaluation of the renewability of fossil groundwaters should include hydraulic analysis that consider their responses to abstraction and shifts in climate.
