A map of groundwater storage trends for Earth's 37 largest aquifers using GRACE data, showing depletion and replenishment in millimeters of water per year. Twenty-one aquifers have exceeded sustainability tipping points and are being depleted, and 13 of these are considered significantly distressed, threatening regional water security and resilience.
