A wave of new research using decades of NASA satellite data has uncovered a dramatic and accelerating loss of freshwater across the planet. Scientists have found that Earth's continents are drying out at unprecedented rates, with overpumping of groundwater, climate change, and rising temperatures driving this crisis. The depletion of underground aquifers is not only threatening water security for billions but is now contributing more to sea level rise than melting glaciers. Four major 'mega-drying' regions have been identified, all in the Northern Hemisphere, highlighting the global scale of the problem. Experts warn that urgent action is needed to manage water resources and prevent severe consequences for food security, ecosystems, and human populations.
