Researchers say warming has pushed global soil moisture into long-term decline, raising wildfire risk and threatening aquifers and river flows worldwide.
On Thursday, August 6, 2026, a study in the journal Science concluded that global soil moisture is in "permanent" decline because of our warming climate.
Researchers warn the world has entered an era of "global water bankruptcy," in which drying continents transfer mass to oceans, altering Earth's rotation on its axis.
About 70% of major aquifers exhibit long-term declining trends, including the Ogallala Aquifer, while rivers like the Colorado, Indus, Yellow, and Tigris-Euphrates show substantial flow changes.
The National Aeronautics and Space Administration reports that human-induced climate change has more than doubled extreme wildfire activity worldwide, as hotter temperatures evaporate soil moisture.
Legislators must enact policies to cut emissions, conserve water, and protect Earth's life-support systems, as vital water and power resources will reach maximum usage sooner than later.
