Satellite images reveal shocking groundwater loss in California

he severity of California’s drought continues to shock, with the latest example coming courtesy of NASA.

The space agency’s two Gravity Recovery and Climate Experiment, or GRACE, satellites have been been in orbit since 2002, making highly sensitive measurements of Earth’s gravity field. Variations in the gravity field can be caused by a number of factors, including the amount of water stored underground in soil and rocks.

This week, scientists working on the GRACE mission released a series of images that reflect the drastic loss of groundwater over the last dozen years.
