New map reveals where humans are adding and removing fresh water

A study using GRACE and GRACE-FO satellite data from 2002 to 2025 identified 94 regions with abnormal changes in freshwater storage. Losses averaged 45% higher than previous estimates, and 40 of the 94 regions are driven mainly by human activity.

• GRACE and GRACE-FO data cover 2002 to 2025
• Freshwater losses average 45% above earlier estimates
• 40 of 94 regions are driven mainly by human activity
• Northern India, southern Iran and the U.S. High Plains lose the most
