Earth’s Soil Is Drying Up. It Could Be Irreversible

The amount of water stored on lands across Earth’s continents has declined at such staggering levels that changes are likely irreversible while humans are alive, a study published Thursday found. The losses in soil moisture — a result of the planet’s climate conditions and prolonged droughts — already pose issues for farming, irrigation systems and critical water resources for humans. But it also affects sea-level rise and Earth’s rotation — datasets the research team used to better track water storage for decades longer than previous studies.
