Climate change may cause taps to run dry in parts of North America, the Mediterranean, southern Africa, and Asia within a decade.
A new study in Nature Communications warns that “day-zero droughts”—where taps run dry—could hit parts of North America, the Mediterranean, southern Africa, and Asia within the next decade due to climate change and rising water demand.
Using multiple climate models, researchers found that continued fossil fuel use could lead to severe, long-lasting droughts in nearly three-quarters of drought-prone regions by 2100, with some areas like the western U.S. at risk by the 2030s.
These events stem from prolonged dry spells, falling reservoir and river levels, and growing urban and agricultural demand.
Cities including Cape Town, Chennai, and Los Angeles have already faced near-crisis conditions, with low-income communities most vulnerable.
The study stresses urgent action is needed to shift to clean energy, improve water management, and limit water-intensive industries in vulnerable zones, though it did not fully account for groundwater.
Experts call the findings a critical warning of mounting global water stress, even if exact timing remains uncertain.
Dentro de una década, el cambio climático podría hacer que los grifos se sequen en algunas partes de América del Norte, el Mediterráneo, el sur de África y Asia.
