Renewability of fossil groundwaters affected by present-day climate conditions

Key Points

• Fossil groundwaters show significant changes due to current climate conditions, affecting their renewability.
• About a 30% decline in usable aquifer water was observed over a decade in regions with extreme climate shifts.
• Observational analysis across various regions highlights the urgent need for sustainable aquifer management practices.
• Findings emphasize the importance of adapting water resource strategies to changing climate patterns for future sustainability.
