Are We Losing Earth's Groundwater?
The latest data, unfortunately, has warned that much of the Earth’s groundwater is drying up. NASA recently reported that 21 out of the world’s 37 biggest aquifers (rock or sediment holding groundwater) have lost groundwater.

Recent data collected via satellite and analyzed at the Institute of Geodesy at TU Graz found that Europe severely needs groundwater. It was already understood that the continent had suffered a drought since 2018. Data has confirmed that groundwater levels have been consistently low since this year despite extreme weather such as flooding.

The data was collected and analyzed by a team of scientists at the Institute of Geodesy at the Graz University of Technology as part of the EU’s Global Gravity-based Groundwater Product (G3P) project. The team used cutting-edge technology that leverages data from two satellites named Tom and Jerry, which orbit the Earth at a distance of around 200 km apart and a polar orbit of 490 km in altitude.

The distance between the two satellites is vital to understanding changes in groundwater. This is because land mass increases the speed of the preceding satellite, with the following satellite lagging. These changes in distance between the satellites over large land masses are used to determine precise changes in the Earth’s gravitational fields.
